Volatily Scalp

Daylight Saving Time (DST) and Changes in the Trading Time

2011-03-18T01:03:00.008+08:00

Finally after 3 months, today EA Pipscola_Y02 again suffered big losses. And once again this happens when the DST on / off is applied. In accordance with the schedule, began on March 13, 2011 the United States to apply the Daylight Saving Time (DST)and then to be followed by European countries on the last Monday in March.
I do not want to blame the time as the cause of this loss. Because even if I change the trading time 1 hour earlier, it's still could not prevent me from the loss. But at least I already have a conclusion about what to do when there is change in time zones.
Adjust Trading Time with the U.S. Time Zone
When the application of Daylight Saving Time (DST)ends, I have an opinion about what should be done. And I think that right now I have to do the same. We must adjust the time trading with the time zone used on the American market. Actually the logic is very simple, because we transact after closing the American market. It's only natural if we follow the time zone used by the U.S. market.
It is different if you run a trading system that deal only in the European Market. Either simultaneously with the Asian market or not, but before the U.S. markets open. In this case, you do not need to change trading time.
Finally, for the moment I change the trading time of Pipscola EA to 22-0 (GMT +1).

Variations of Range Breakout Strategy

2011-03-08T15:22:00.006+08:00

N-Bar Range Breakout
Range breakout is a very simple trading system that is very easy to learn for beginner traders. Observe the highest/lowest in 1 or more bars. Put a limit order a few pips away from that highest/lowest. This is the classic N-bar breakout strategy.
Session Range Breakout
This is just a variation of classic N-Bar range breakout strategy. The main difference of this system with N-Bar range breakout is the bar(s) that was observed to be static and associated with the time. Although the session in the forex is often associated with time zones (Asia, Europe and America), but in this case does not always mean that. Because they are static, the rules of this system : "Observe the highest/lowest of the HH:MM to HH:MM".
Opening Range Breakout
I think this system is still a variation of classic N-Bar range breakout. This system is an adaptation of the stock trading system called the Early Morning Breakout System.
This term is actually less suitable in Forex. This is because every Forex broker uses a different time zone.
Bar 0(GMT +1) Range Breakout
Now it's up to you want to call what this breakout kind of. Observations made on H1 timeframe. And probably only suitable for the USDJPY pair. I didn't test it yet on other pair.
For more details, I make an EA to test this system. I arranged to take buy position when price penetrates the high (bar 0 gmt +1) + 10 pips. And vice versa on the sell position. I do not use a limit order and let the EA work in stop and reversal mode. But I do not restrict to just open a trade position. If yesterday's EA took a buy position, and if today prices penetrate the high (bar 0 gmt +1)+10 pips, EA will add a new buy position.

My Backtest is Running Slowly

2011-02-15T11:11:00.002+08:00

I think there is something very disturbing in the development of EA Pipscola. EA is running very slow in backtest mode. There are several possibilities that be the cause. I read some suggestions for upgrading a PC that I use. Others suggested to optimize the program code on Indicator and Expert Advisor.
But the problems that I experienced only occur in the period 2009-2010. Weird is not it? For more details, as I do backtest using data from the period 2005-2008, the time needed to complete this process faster than the period 2009-2010. This is very annoying. To be honest until now I can not explain why this could occur. But from this incident I could learn a few things.
Processor
Processor is the core of a computer. The speed and performance of a PC can be seen from the processor it uses. Processor that we usually use today are no longer using a core, but consists of several cores. Okay, it allows us to open several applications at once (multitasking). It's nice when we're optimizing an EA and at the same time still be able to enjoy High Definition video.
Maybe you think if I let Metatrader run alone then the optimization process will run faster. Unfortunately what you think only happens if my computer is still using single core processor. If my computer uses dual-core processor, then there is a unused core practically by Metatrader. EA only runs on a single thread. Even all the EA that are running on a Metatrader share the same thread.
Optimizing the code
In the end I found a way to increase the performance of EA Pipscola during backtest. Apparently myscreen function () which I use to display some information on the chart causes backtest process becomes very slow. So I modify the code to be executed only during live trading. You do this by adding the code

if (! IsTesting ())

just before calling

myscreen ();

. So the complete code is now

if (! IsTesting ()) myscreen ();

this code can be applied to all versions of Pipscola. This optimization can improve the performance of EA Pipscola more than 20% during backtest.

PipsCola_Y02

2011-01-02T12:26:00.008+08:00

Happy New Year 2011. Hopefully this year to be better than last year. I want to tell you that Pipscola Y version will soon be updated. Similarly, the version of D. But time will not be the same, because I still need a little time to complete the version of D. And I'll send this update to your mail box tonight.
Changes to the version of Y only occurs in an exit rule. In version PipsCola_Y01 exit only determined by the value of ATR (Average True Range) and MaxProfit. So in version PipsCola_Y02 just reinforces that EXIT must be done above and below the Moving Average on the time frame H1.
External Variable PipsCola_Y02
MaTP
To adapt the new exit strategy, I added a new External Variable. The default value of this (MaTP) parameter is 5.
If you want EA always close the all position above / below the MA, then you can set the parameters MaxTP in value as much as possible, say 100.
MinLevel
This parameter set a filter that is owned by PipsCola_Y02. In previous versions, this parameter is hidden. Now you can optimize it. The default value is 0.4.
VS_Pipscola_Y02 use charlotte3.dll library version 1.0.0.2. You have to rename the previous library to make it work on the same terminal.
Backtest result (Spread is 2.8, and some missing historical data in October 2010):

MaTP 5, MaxProfit 10, January 2009 - October 2010

MaTP 5, MaxProfit 10, November 2010 - December 2010

MaTP 5, MaxProfit 100, January 2009 - October 2010

MaTP 5, MaxProfit 100, November 2010 - December 2010

MaTP 10, MaxProfit 100, January 2009 - October 2010

MaTP 10, MaxProfit 100, November 2010 - December 2010

VS_PipsCola_Y01 Backtest Result

2010-12-06T12:13:00.004+08:00

This is the backtest result of VS_PipsCola_Y01 EA. I use historical data from Alpari broker. Backtest period is January 2009 to October 2010, while spreads in this backtest is 2.8.
I think between all my EA, then this VS_PipsCola_Y01 that gives the best backtest result on USDJPY pair. Unfortunately the filter which is used by this EA may not work well when tested using historical data from other brokers.
Actually I have some variety in this EA, only because of time constraints I did not get to test everything. So I thought I'd better release a version of Y01 to have time to test all such strategy.

VS_PipsCola_Y01 Trading System Parameter

2010-12-05T18:21:00.003+08:00

Here is an explanation of the parameters relating to the trading system. For parameters associated with Money Management you can see into VS_PipsCola_D01 Money Management Parameters. Similarly, the parameters associated with the Trading Time, you may refer to VS_PipsCola_D01 Trading Time Parameters.
MaxProfit = 10, this parameter is similar with vs_eurocross has. This parameter serves to set the maximum profit in pip value.
MasterPeriod = 3; this parameter set period of keltner channel on the Time Frame H1.
SignalPeriod = 12;
ChannelPeriod = 11;
I think if you want to optimize VS_PipsCola_Y01, then just just optimize these two parameters. However for a complete optimization, you can also optimize the MinRangePerTrade and MasterPeriod parameter.
PipAfterFractal = 2; VS_PipsCola_Y01 using fractal trailing stop. This parameter controls how many pips pips from the fractal the stop losses is placed. And You need to know trailing stop is activated only after trading hours passed.
I think it's just that I need to explain. Since all other parameters similar to those in VS_PipsCola_D01.

I Thank You

2010-12-02T14:06:00.003+08:00

Actually I hope today I can send VS_PipsCola_Y01 to all of the users of PipsCola EA. However, because of one thing, I can not do that today. But I'm still trying to get it done this weekend.
I also want to thank the blogger who has written reviews about Volatily-Scalp EA. Whether it be in the form of forward test or also doing translation into Japanese. That's why I've put these links on this blog. And I try to always update it, or contact me if you want to place your link.
And specifically if you are in Japan, you can visit this blog. I thanked him for his efforts that translate PipsCola EA manual into Japanese.

Trading Result November 30, 2010

2010-11-30T14:10:00.003+08:00

Today's trading results are positive. Charlotte produced 3 pips while VS_PipsCola_D01 produced 12 pips. Although the profit gained less than a week ago, but at least VS_PipsCola_D01 always give more than 10 pips profit. Not only that, the average holding time is relatively short. You can analyze it through my myfxbook.
As I have often expressed that there would be Pipscola new version to work in pair except for EURUSD. And it seems it is the USDJPY pair. But unfortunately this new version is not in the form of an upgrade from older version. However, this is a new EA. I'm very difficult when trying to combine them, so I thought its better to separate them. And its name is VS_PipsCola_Y01.
I think 1 or 2 days ahead, this EA will arrive in your paypal mailbox.

Channel Trading, Scalping With Keltner Channel

2010-11-26T00:57:00.005+08:00

One of the most complicated thing that I feel when making Volatily Scalp system is anticipating a drastic decline of Average True Range (ATR) in record time. As a scalping system based on the trading channel, determining the length of the period Keltner Channel is very important. This is because the channel width of the Keltner Channel indicator can change over time depending on market volatility.
In the Channel trading, generally upper channel and lower channel act as overbought and oversold levels. Buy position is taken when the price hits or below the lower channel and sell position taken when price hit or above the upper channel. No matter with indicators that used to create the channel. As for an exit strategy there are many options but generally is the opposite of the entry signal itself.
Now let us look at the chart below. On this chart I put a Keltner Channel indicator (20.2). Red vertical line to mark the beginning of the transaction (at 21 GMT 1). I also placed an indicator CK_Speed (20.50) and ATR. (20).
It should VS_Eurocross can get sell signal as I describe in the chart above. Although the position of an exit may be slightly different. But what I want to show is how the system with the Keltner channel (20.2) miss a couple of profitable trades. Therefore, I draw 2 horizontal lines that act as a channel to clarify what I mean.
I've been plagued with this problem. And it seems impossible to know what is the optimal length of Keltner Channel Period at any time. But when I'm working on EA's Charlotte, I always strive to capture this pattern. I use the High / Low of the last 2 bars when the entry signal occurs as a place of exit. The results with the same chart as above, charlote EA is more aggressive.

Trading Result November 19, 2010

2010-11-19T11:46:00.004+08:00

I do not know what happened with my Mt4stats. Detailed statement was not published correctly. So I will publish my trading results today. But because today is the last day in this week's for EA to work, then I will post the results of trading in a week.
Today VS_PipsCola_D01 EA gives very good results where the EA makes profit of 15 pips. That means a quarter of the stop losses. In contrast to yesterday where the EA deal when liquidity is very low, today EA deal while liquidity is still high. All transactions are made when Average True Range ATR (5) is still above 10 points and the transaction can be closed quickly. And I think this is in conformity with what I expected. Stay ahead we see whether such results could be more frequently obtained.
For the trading results in a week then the results remain positive. This is because charlotte2 more aggressive this week so it can cover the losses suffered by VS_PipsCola_D01. It seems they are the right partner.
Regarding the development of VS_PipsCola, right now I still focus on the pair USDCHF and USDJPY. There is a good improvement of the USDCHF pair. But on the other hand Charlotte integration into PipsCola also went smoothly. Hopefully PipsCola update can be released as soon as possible . If its possible in the beginning of December or at least before the new year. I'll be working on it

A Loss Trade

2010-11-18T12:46:00.005+08:00

VS_PipsCola suffered a loss today. Although at first could make profit by 8 pips, but a sell position made at 23 (GMT 1) ended with a loss of 60 pips. So for this week, VS_PipsCola has suffered a loss of 44 Pips. This is because yesterday VS_PipsCola make profit as much as 8 Pips.
But I do not think to change the settings to be used. In my opinion, Sell position made at 23 (GMT 1) it is appropriate. Only after that liquidity is very low. I calculate the range (High-Low) at 23 only by 5.8 pips. So very hard to close the trade with a profit at that hour. Unfortunately after at 0 (GMT 1) price moves up and finally touched the stop loss position.
Currently I have a focus to develop PipsCola on another pair. And I have a target to release it before the New Year. But I'm working on it to be released early December, so that there is a chance to do forward test. I have 2 alternatives at this time. Developing PipsCola for USDCHF pair or modify Charlotte2 for including into PipsCola family. I got many requests for the second alternative. But it is very difficult to integrate with VS_PipsCola_D01. And even if eventually PipsCola for USDJPY pair was released, most likely in the form of a separate EA. Maybe I'll give its own version to distinguish it with the version of EURUSD.
I hope you guys have the patience to wait. Because after losses in the EURUSD pair, it is a little distracting me. But I still think that this loss does not deviate from the backtest. So I do not need to change anything, either setting or system. Just you know, I use h_pipscola_alpari setting in My Account, and this is an aggressive setting.

VS_PipsCola_D01 Trading Time On ForexCoJpy

2010-11-14T15:26:00.006+08:00

I want to explain in more detail how to configure VS_PipsCola_D01 trading time. This is to avoid mistakes as there are different time zones held by the broker. I will give examples of how to set the trading time on the broker Forex.Co.Jpy.
And again I would like to emphasize that VS_PipsCola_D01 not transact at weekend and in the beginning of the week. If you are still confused how to set RestrictionDay parameters, then you should just remember the rules. I created RestrictionDay Parameters to prevent the EA deal over the weekend and the beginning of market opening.
To set the trading time on ForexCoJpy then we need to know the time zone used by the broker. Currently, the time zone used by ForexCoJpy are GMT 9. And if I look at this broker does not implement Daylight Saving Time. I know it after seeing the losses that occurred in Charlotte, where the EA deal 1 hour early. At first I thought ForexCoJpy will switch their timezone to GMT 8 when DST ends. And apparently not, so I had to change the trading time.
Let the following parameters of the trading time to brokers ForexCoJpy VS_PipsCola_D01.
OpenHour = 5;
OpenMinute = 0;
CloseHour = 7;
CloseMinute = 59;
EnableXtraTime = False; Unless you want to use it, then adjust the position of True;
XtraCloseHour = 9;
XtraCloseMinute = 59;
For RestrictedDay settings, we can use DAY_OF_WEEK parameter to prevent the EA deal at the weekend. While we use Day_Of_Week2 parameter to prevent the EA deal in the beginning of week. You can just swap it. Furthermore, you can use it to prevent the EA deal on Days and hours you specify yourself. For example, if there is a major event that coincided with the trading time, then you can set this parameter to prevent the EA deal at the time the event occurred. Of course, after the event is finished you have to set it again to prevent EA transact at weekends and in the beginning of the week.
Market closure on forex.co.jpy happen on Saturday. For that the settings are:
DAY_OF_WEEK = 6;
Begin = 0;
End = 23;
To prevent the EA deal in Market Opening on Forex.Co.Jpy Broker:
DAY_OF_WEEK = 1;
Begin2 = 5;
End2 = 8;
Actually, if you fill with Begin2 = 0 and End2 = 23 then the result remains the same. I'm using Begin2 = 5 and End2 = 8 to clarify its usefulness, that preventing the EA deal in the beginning of the week.

VS_PipsCola Installation Guide

2010-11-13T21:20:00.006+08:00

Actually the installation process of an EA is very easy, because you just need to put it in the Experts (folder) directory of your Metatrader platform. But sometimes an EA uses the indicators that are not available on metatrader. And this will be a problem if you can not distinguish between indicators with EA. Not to mention if EA has the library files and include file. All these files should you place it on each folder.
Generally if you install Metatrader on your computer, then they have the same directory structure no matter with your broker. The difference is the name of the root directory. As in the following figure is from Metatrader directory structure of Alpari Broker.

Installing VS_PipsCola
There are four files that you need to put in the proper directory to make EA vs_PipsCola working. The four files are composed of an EA, 2 custom indicator and a library file. Actually there are an others file which are also used by EA vs_PipsCola_D01, but you do not need to worry because the files are already available in your Metatrader.

VS_PIPSCOLA_D01.Mq4, it is the EA. This file must be located at: C:\Program Files\Your MetaTrader \experts
Keltner Channels. Mq4, it is indicator. This file must be located at: C:\Program Files\Your MetaTrader \experts\ indicators
CK_Spee.Mq4, it is indicator. This file must be located at: C:\Program Files\Your MetaTrader \experts\ indicators
Pipscola.dll. This file must be located at: C:\Program Files\ Your MetaTrader \experts\libraries

Because the EA uses external library which is made from C++, then you need to configure your Metatrader platform to allow DLL import. You can do it by pressing Ctrl+O in your chart window, and then the option window will appear. Just click on Expert Advisors tab and you have to check the Allow Dll Import.

Update on Sunday, December 5, 2010.
To install VS_PipsCola_Y01 then do the same as above. What you should know, both use the same indicators. The difference VS_PipsCola_Y01 uses the library named "Charlotte3.dll" while EA file named "VS_PipsCola_Y01.mq4".

VS_PipsCola_D01 Trading System Parameter

2010-11-12T00:28:00.004+08:00

In this section I will explain the parameters of the indicators that are used by VS_Pipscola. So, if you want to optimize the parameters of vs_pipscola, hopefully this explanation can help you.
VS_PipsCola is an EA that works on 15 Minutes Chart. However, it actually observe H1 Time Frame to determine market conditions. Market conditions are determined based on the observations on CK_Speed, ATR, Keltner Channel and parabolic sar indicator. As for putting a more precise entry, EA observe a smaller time frame. Although the observe several time frames, but it use the same length period of CK_Speed, ATR, and Keltner Channel in all time frames observed by the EA. Besides, the EA also allows averaging system.
Here is an explanation of the parameters of VS_PipsCola associated with trading system.
double MasterPeriod = 5; This is the length period used by ATR, Keltner Channel and CK_Speed Indicator on all time frames observed by EA. The use of a single parameter is to facilitate you in doing optimization.
Because EA observes H1 Time Frame, I think this value should not be too big. If you want to do the optimization, I think the minimum value is 3 and the maximum value is 8.
double MaximumAtr = 45; This is similar to filter MaxDayAtr on vs_eurchf. Only VS_Eurchf using D1 Time Frame while VS_PipsCola use H1 Time Frame . The lower you set this parameter value, then a few transactions that may occur. We recommend that you set the value of this parameter refers to the stop losses you want to use. This means that the value of your stop losses should not be below the value of this parameter.
double H1InitialDev = 0.1; This parameter is used to adjust the deviation of Keltner Channel on H1 time frame. The larger the value of this variable the more difficult to place a trade.
double M15InitialDev1 = 0.8;
double M15InitialDev2 = 0.8;
The two variables above are used to adjust the deviation of Keltner Channel on the 15 Time Frame. PipsCola EA actually can be arranged to use a different deviation based on market condition. But if you want EA always uses the same deviation, then the two variables must be equal. Since these variables set the deviation of the Keltner Channel, so the smaller the value of these variables will make EA more aggressive.
If you optimize these variables, then the maximum possible results would be obtained if you set a value of M15InitialDev1 less than M15InitialDev2. While the optimal value of the two variables is likely to lie between 0.5 to 1
int MinRange = 5; parameter is similar to the one owned by vs_eurocross. It set the minimum distance between price and moving average. And the rule is clear, the value of this parameter is greater than the Spread + 1.
double MinRangePerTrade = 10; If EA is allowed to take more than 1 same position, then this parameter will set the minimum distance between the same trade position.
int MaxTradePerBar = 1; this parameter to set how many open positions that may be taken on every bar. I said open position, because although the value of this parameter is 1, the EA may transact more than 1 per bar. Suppose that EA took a position and then close the position in the same bar, so if there is a new signal EA will continue to execute the signal.
But despite it all, this parameter can make EA become more aggressive even if you do not optimize the other parameters.
bool AllowHedging = true; this parameter to set whether the EA could take 2 opposite positions (buy and sell). Of course this is closely related to the regulation that is used by each broker.
bool UseSecondaryPeriod = false;
double SecondaryPeriod = 3;
I deliberately wanted to explain these variables just in the last section. This is because you can ignore these two variables. But if you are curious, then this is actually the second Keltnert channel observed by the EA in the H1 time frame. You can optimize this parameter. But you have to adjust the UseSecondaryPeriod with True.And another thing if you manage to set SecondariPeriod at 5, means not to change anything, because it has the same length period of MasterPeriod. It is highly experimental, so please try it yourself. Although in my opinion the value of this parameter is only optimal if less than MasterPeriod, but I never optimize it.

VS_PipsCola_D01 Money Management Parameter

2010-11-11T16:49:00.002+08:00

I think VS_PipsCola_D01 was ready for distribution. But before that I better explain its parameters first. I probably will not include the manual, so I'll publish them all online via this blog. And for simplicity I will divide these parameters into several sections. And this section will explain the parameters associated with Money Management or any parameter that affect in your risk. For Trading Time section, you can see in the VS_PipsCola Trading Time Parameter.
It could be said that all of my previous EA will fail to calculate Lot size correctly on non Dollars account. Therefore, I try to change it in order to accurately calculate the lot size for all types of deposits. Hopefully, this formula works, but if not you should be forced to perform calculations manually.
The following parameters are used by VS_PipsCola_D01 related to Money Management.
MM bool = true. This parameter is telling the EA whether to calculate the lots base on the available margin. If this parameter is set with True value, means that EA will calculate the number of lots based on the Free Margin. Otherwise the EA will look to the other parameter to determine the lot size.
Double RiskPerTrade = 5; parameter is only meaningful if you set the MM parameter with True. RiskPerTrade means the amount of margin that will be used for 1 transaction. RiskPerTrade = 5 means that the margin for each transaction is 5 percent. However, the total margin that may be used by the EA is also influenced by other variables namely MaxTradePerPosisition.
MaxTradePerPosition = 3; this parameter to set the number of transactions allowed for each position (Buy / Sell). However, this parameter will affect your risk, because the larger the value of this parameter, the more margin to be used. If you set RiskPerTrade with 5, and your MaxTradePerPosition is 3, meaning the amount of margin that is used to open the three transactions are 5 x 3 = 15.
Double Lots = 0.1; parameter is only meaningful if you set MM parameters with the False value. Regardless of the value that you fill in this parameter, over the free margin is sufficient, then this parameter will be used to determine lot size for every 1 transaction.
int StopLoss = 60; I think this is very clear parameters. You must determine how many stop losses are used for each transaction. You do not need to worry if your broker uses 4 digits or 5 digits. 60 always means 60 pips does not matter with your broker digits.
int MaxLossesToStopTrading = 1; Although this parameter does not affect the calculation MoneyManagement, but this is to adjust your risk management. This parameter will tell the EA to stop to take a position if EA had suffered losses at the value of this parameter. Yet EA will continue to maintain any position that is still open.

VS_PipsCola_D01 Trading Time Parameter

2010-11-11T14:52:00.003+08:00

I think VS_PipsCola_D01 was ready for distribution. But before that I better explain its parameters or external variable first. I probably will not include the manual, so I'll publish them all online via this blog. And for simplicity I will divide these parameters into several sections. And this section will explain the parameters associated with Trading Time setting. For the Money Management section, you can find in VS_PipsCola_d01 Money Management Parameter.
Default trading time is 21-23GMT+1. So please adjust your trading time if your broker time zone is not GMT+1. The following parameters are related to trading hours:
Opening
OpenHour = 21;
OpenMinute = 0;
Two variables above are used to set when to start trading. Their combination will tell the EA what time to begin to trade. OpenHour=12 and OpenMinue=0 means that EA will start to trade at 21.00.
Closing
CloseHour = 23;
CloseMinute = 59;
Just like the opening, CloseHour and CloseMinute are used to set when to stop trading. Combination of CloseHour and CloseMinute will tell the EA what time to stop to trade. CloseHour=23 and CloseMinute=59 means EA will stop to trade at 23.59.
Extra Time
bool EnableXtraTime = true;
int XtraCloseHour = 1;
int XtraCloseMinute = 59;
The three parameters above may be rarely used by EA. I add this parameter to increase the trading hours. But this only applies if EA still has an open position. And EA is just going to take the same position with the open position. For example if the EA still hold a Long position and the trading hour has been passed, if extra time is enable then the EA will only take a Long position and never take the opposite position.
To enable the extra time you have to adjust the EnableXtraTime parameter with True. The rest it just like to set closing hour. So XtraCloseHour=1 and XtraCloseMinute=59 means the extra time will end at 1.59.
Restricted Day
int DAY_OF_WEEK = 5;
int Begin = 0;
int End = 23;
Day_of_Week2 int = 1;
Begin2 int = 0;
End2 int = 5;
In general I do not allow the EA to trade at the Beginning and Closing market. And to arrange for the EA does not trade on these days, I am providing as much as 6 parameters.
Parameters Day_of_Week2 and DAY_OF_WEEK can be filled between 0 to 6 that represents the days from Sunday to Saturday. While the Begin, End, Begin2 and End2 parameters represent the hour for the day.
So DAY_OF_WEEK = 5, Begin = 0 and End = 23, mean EA is not allowed to transact on Friday from 0 to 23 o'clock. While DAY_OF_WEEK = 1, Begin2 = 0, and End2 = 5 means that the EA should not trade on Monday from at 0 to 5 o'clock.
All you have to note that this is a configuration for Alpari server which their Time Zone is GMT+1. And you should also remember, that the trade in Alpari Server starts Monday at 0 GMT+1, while the actual Forex Market is open on the Sunday at 23 GMT+1. So if even if your broker time zone is the same with Alpari, you also need to find out if they start trading at 23 or 0. If your broker start to trade on Sunday at 23 GMT+1 o'clock, prevent ea to trade at this time.

VS_PipsCola Backtest Result in 2009

2010-11-07T20:32:00.005+08:00

Although at the moment VS_PipsCola has the best result on EURUSD pair, but seeing the results of the backtest on the other pair, it could be in the future VS_PipsCola will support several pairs at once. There are actually an interesting thing from backtest result on FOREX Major Pairs (USD-JPY, GBP-USD, USD-CHF and EUR-USD). In general VS_PipsCola gave results that did not disappoint during the year 2009. Moreover, I only use the same settings on all of these pairs.
Settings that I use on all of these backtest are:
Trading Hour: 21-23
Lot: 1
MaxTradePerBar: 1
MaxTradePerPosition: 3
STOP LOSS: 60
Spread for each pair on the backtest:
USDJPY: 2.8
EURUSD: 1.7
GBPUSD: 2.8
USDCHF: 3.2

PipsCola USDJPY 2009

it looks better then Charlotte at the same periode.

PipsCola USDCHF 2009

It seems somewhat promising although tested with a high spread conditions.

PipsCola GBPUSD 2009

Next post i'll show you the backtest result in 2010 and so we can see what pair that possible to be supported by VS_PipsCola.

VS_PipsCola is EA Donation

2010-11-06T21:01:00.004+08:00

It seems VS_PipsCola will become a new family of Volatily Scalp. I am targeting to be published this month, or no later than early December. But I apologize, I'm not going to save VS_PipsCola in my 4shared folder for downloaded for free. I'm just going to give it through donation or the trader who is registered under my affiliate program at the Alpari Broker.
A little hard for me to apply this rule, and I've tagged to this Blog as a place of free EA. But I must say that I need a rather large financial support at the end of this year. But I also do not want to sell this EA to someone to be sold in bulk. I think Charlotte just enough. I also avoid what is called hype. I publish the Forward Test of Charlotte in order to avoid things like this. So you can judge for yourself how the ability of Charlotte, when someday you find this EA in the market. I'm not saying that all commercial EA is hype, but you should listen Pipturbo case if you are newbie on the EA.
When I published EA and showing the results of backtest or forward test, then the decision is in your hands as the investor. There is no guarantee that the backtest results, even a forward test that is running, will remain similar in the future. But I still think that as an investor you still need a backtest results. How big is the difference between the backtest and real trade that you get, could be a measure to stop or continue using the system. Even just by looking at the Risk / Reward, you may be able to assess whether the EA or trading system is suitable with your profile. And I always put myself as an Expert Advisor Developer, and not as people who are already successful with a trading system, then make it into an EA. Sure, I'm not asking donation if am a successful trader.
About what features you want from VS_PipsCola, please give feedback via this post or via email, hopefully I can apply them.

PipsCola, EURUSD Scalping EA

2010-11-04T15:50:00.003+08:00

Although lately I'm busy working on Charlotte, I am taking the time to continue making my other EA. Actually since a long time I want to make scalping EA that work on the EURUSD pair. Even you should know that my first EA (VS_EURCHF), I initially created to work on the EURUSD pair. As the most liquid pairs in FOREX, with low spreads, should be easier to apply scalping method on EURUSD pair.
And if you watch my demo account, there you will see the transactions on the EURUSD pair. Although not yet fully finished, but I still do forward test. A bit disappointing, because it already suffered two losses within 1 week. But I still continue to maintain continuity between the backtest and forward testing. The loss occurred because I have not had time to optimize the target profit and also have not had time to optimize the variable stop losses.
And finally I have a special time to fix it, and I think EA is completed.
I feel very thirsty when finished working on this EA. But just remember if I have not given a name. Because I work on this EA based on VS_EURCHF. If you enjoyed dessert Charlotte, then you may be interested to drinking PipsCola. But I hope you do not try this one, MarginCola!

Day Light Saving Time (DST) and Trading Time

2010-11-03T11:49:00.005+08:00

Alpari switch their Server Time Zone in relation to the completion of Daylight Saving Time (DST), which was from GMT+2 to GMT+1. The change is interesting because many Expert Advisors that work only at certain hours. Are the settings on expert advisor must follow this change? Suppose if you previously used 21-23 on VS_Eurocross EA, whether now have to use 20-22 or remain at 21-23?
Maybe if the change is simultaneously carried out by countries that implement it, then it's not too complicated. But what happened today, where the U.S. and other countries will change their Time Zone next week. And brokers are likely to apply the Time Zone to follow regulations in their respective countries. But despite the changes made at the same, the question of trading hours arrangements may not be answered.
I think for the moment, we should remain based on the DST before all nations use standard time again. So if your trading time 21-23, means you have to change to 20-22 with the assumption that your broker turn off Daylight Saving Time (DST) . If DST is disabled entirely, then we go back to Trading time 21-23. But if you are confused determine your trading time associated with the change, then the safest way is reducing the duration of your trading time. The trick is to change your Closing Time an hour earlier. So if your trading time is 21-23 then you change it to 21-22, and you do not have to worry about whether your broker to apply the Daylight Saving Time (DST) or not.

Parabolic SAR and Fibonacci Lines

2010-10-24T21:36:00.005+08:00

It could be said that I include the Parabolic Sar indicator in all the EA that I made today. And although generally parabolic sar is used as trailing stop as well as stop and reversal system, we actually can use it in another perspective. This is what I get when I learned about Fibonacci lines. I am very confused where to place the swing high and swing low. To make it a mechanical system, there must be clarity where to put those lines.
If we observe any signal change indicated by the Parabolic Sar, then it could be a clue where we put the Swing High / Low Swing of the Fibonacci lines. If you set the parabolic step with the value 0.002, then you will get a good starting point for putting your Fibonacci lines. Place the Swing High / Swing Low right at the signal changes of the Parabolic Sar. If the Parabolic Sar change it’s direction from sell signal to buy signal, it means you should place swing low at the first dot of Parabolic Sar. Actually it is the same whether you place it at the lowest prices that occurred in the previous signal. Now to put the swing high is easy, you just follow the price movements while the Parabolic Sar is still giving buy signals.

But that's just my way to reinforce where to put Fibonacci lines. As a tool, anyone can use an indicator with a variety of ways and interpretation. So, how about to scalp using these indicators? I have no idea.

Forward Test Result and Manage Account

2010-10-17T12:15:00.005+08:00

This week I was able to publish the results of Charlotte2 forward test. Actually you can already see the results since a few days ago. Since I've put a link to the publisher the right of this blog. But it's running on the Demo Account at Alpari. While I should post it manually what running on real accounts. In the next few days, I will publish automatically statement of real account with respect to the performance of my VPS.
On average, each account has only 2 deals on this week. But at least this is better than earlier versions. Especially if you see that EA is only working 3 hours a day and 4 days a week. Yes, just 4 days a week, because EA does not work at the opening of trade and the end of the week. But configuration error occurs on account of real trade, I forgot that trade on forex.com broker starts an hour earlier than Alpari. And I forgot to adjust the parameters that govern it. This allows the EA to trade for 1 hour in early trading. But fortunately the transaction is not fatal although almost touching the position of stop losses.
You can see the results of forward test of the demo accounts on my MT4 stats. And for a real account you can see in the picture below. You can compare it to the results of last week.

Professional Account

Standard Account

I also want to give the opportunity for some people who want to invest in FOREX using charlotte to contact me at ch1qho@gmail.com. Before I could decide when and how charlotte later published, then Manage Account only alternative I can give at this time.
And for traders who have registered in the broker Alpari through my affiliate link, I will give a free service Manage Account of any type of account you have.
Happy weekend

Trailing Stop

2010-10-13T13:28:00.004+08:00

Do not let a profit turn into losses. This is a principal in trading system that we often hear from the master trading. If prices move in accordance with our position, use a trailing stop or put our stop losses in the break event point. So if you already have a profit of 10 pips, quickly activate the trailing stop. What happens then prices turned direction and touches your stop losses kicking you out, then turned again in accordance with your position and this time the price moves fast. Ho .. ho .. ho. if I were near you that time, believe me I would also go as fast as possible.
Trailing Stop With Fractal and Bar High-Low
There is a change from a trailing stop method that I use this time(Charlotte). Previously I used the Keltner Channel, so this time I use 2 Fractal and the latest 2 Bar as stop losses. But I still use Keltner Channel as a guide to do the trailing, only the position of stop losses are no longer on the Keltner Channel itself.
In order to obtain the position of stop losses I compare the highest / lowest price of the last two fractal. I compare this price again with the last 2 bars. I use the last 2 Bar considering the highest / lowest price could be in one of this Bar. Trailing stop itself is activated when the price penetrates the Upper / Lower channel of Keltner Channel indicator.
The principle I want to reduce the risk in trading. While difficult to make a profit, then we better think about how to reduce losses. And trailing stop this is one way to reduce the risk of each transaction.

The Forward Test Result

2010-10-10T00:28:00.004+08:00

This weekend I had time to post my EA performance in a forward test. Previously I just post my backtest and some ideas of my EA. Forward Test carried out since August 18, 2010 and use 3 accounts, 1 demo account on Alpari as well as 2 live accounts on ForexCom. But this is an early version of my project, which later I improve it as an intermediate term system EA. In the process, EA is already upgraded once. And there is one advantage of this EA, it was able to transact from at 19 to 23. But the problem with the ability to work longer, not followed by an adequate amount of transactions. So it makes sense to change the system from scalping system to intermediate system.
I would not be surprised if later on a lot of scalping system that works on USD JPY pair. Moreover, if the system only works after the closing of European and American markets. My test showed at least my EA to make profit in the last 3 years. And here's a surprise, I did not use a filter other than limiting the time to trade. So I just rely on the accuracy of the trading signal. To anticipate the worst conditions, I apply a rigorous risk management. Yes .. I have to regulate how much of losses suffered by the system may in a day. Try to open your MetaTrader, then observe the movement of USDJPY after the closure of European markets in the last 2 years!
I'm hoping one of the variants of this EA can be used for free via this blog. But it really depends on the outcome of our conversation later. Because maybe if you are interested to try this EA, I am afraid you will be hard to get it.
Well here I show the Detailed statement of my forward test:

Have a Nice Weekend

Combining 2 Expert Advisor

2010-10-06T22:52:00.007+08:00

I'm making an expert advisor. I call this project Charlotte. Initially I was asked to modify vs_eurocross to work on USDJPY pair. I accept the job, and I began to modify vs_eurocross. In the end, with various modifications I get a pretty good backtest results. Unfortunately, the number of transactions carried out very little. Even stop losses should be set at 100 pips. However, Forward test remain to be done both on demo and live accounts. And the result, just like the backtest, the number of transactions is very small but for the average profit per transaction a little better than vs_eurocross.
Since seeing the results of the first backtest, I already have ideas for changing the character of this EA from scalping system to intermediate term system. The problem I was asked to create a scalping system, but I also do not want to forget this idea. Finally, I trace my code from scratch, and marks the point where I have to separate between scalping system and intermediate system. And finally I was satisfied, because I get 2 pieces of EA as well. And the last step I need to do is merge them back into an EA.
Actually I have shown my backtest results for the scalping system. This time I will show it again, and also compare it with the intermediate term system. I did a backtest from the period January 2009 to August 2010. The spread in my backtest is 2.8, this is the highest spread is given by Alpari for USDJPY pair. While the risk during the backtest period is 10 percent and 60 pip stop losses.

Especially for the intermediate term system, I do backtest 2 times. This is to show the scaling out method that I provide on this system. With the scaling out method, EA will take half of the profit when it has reached half of the target. So let's suppose the profit target is 20 pips, while EA have got profits of 10 pips, then EA would liquidate half of these profits. Both scalping system as well as intermediate-term trading system, just take a position on certain hours. For scalping system I chose to work at 21 to 23. As for the intermediate term, I arranged to work from at 19 to 1. Time zone is not defined, but refers to the broker Alpari.

without scaling out

Using Scaling Out

Scalping System

There is strong interest for me to combine this system. For the both EA can perform transactions at the same time. Maybe not in the precise timing, but at least still in the same bar. Thus the new strategy can be applied to select the system which would take precedence. Maybe it could produce more, but I myself can not confirm, because until this post I made, the process of merging the two EA has not yet been completed.

Finding Optimal Value without Optimization (Part 2 of 2)

2010-10-04T18:32:00.010+08:00

In my opinion, lack of MetaTrader is a lack of information we get from the Detailed Statement. Perhaps because of the Detailed Statement of MetaTrader is also used by the broker to send to its customers. Clearly it is enough of the investors, but not for trading system developers. As an illustration, you can observe the MQL championship. At the end of the championship, you can see how they analyze the performance of a trading system. I wish such that report will be in the detailed statement.
I will show the detailed statement of the results of my test on my previous post.

Detailed Statement 19 - 4

You can notice that the detailed statement only provides general information about the profit / loss. But consider the following picture. This journal is a place where an EA can write down it's activities.

Profit hari 4: 82 Los hari 4: 15 sumprofit: -138.42
What does it mean? EA to report profit / loss based on the Day(Hari). Profitable trades on the 4th day (Thursday) is 82 (trades), while losses is 15 (trades). And Net Profit is -138.42 ($).
Profit Jam 23: 37 Los Jam 23: 0 sumprofit: 190.39
What does it mean? EA to report profit / loss hourly. Profit for all trading at 23 is 37(trades). And losses for all trading at 23(trades) is 0. And net profit for all trading at 23 is 190.39 ($).
So just based on the above information I could find out that I will get optimal results if I restrict trading time at around 21 to 1. But you are wrong if you guessed that the backtest results from 21 to 1 will be the same if you add up the net profit from 21 to 1. From the reports mentioned above, only one is for sure, that I was not allowed to start trading at 19! For more details, let you see the following picture:
n backtest I did, I set the EA only took one trade for each position. While EA could have produced more than a signal at a certain period. From the above picture there are 5 trades that generate profit (1 trade per hour), but on my backtest, the EA is only allowed to take a trade for each position.
But anyway, for me the above approach is sufficient for my EA. Based on reports from my journal, i perform 3 backtest with different periods, but all of them lie between 21 and 1.

trading time 21-0

Trading Time 21-23

Trading Time 23-1

You can download the function that i used to create hourly/daily detailed statement. There are only 2 functions in text file, deinit() and Analyze().Moreover it just loop from 19 to 6.
Maybe you can make it better, and have a more brilliant idea. Every trading system has a different characteristics. What I would like to make is how to get the optimal value of a variable without any optimization. Or at least when designing an EA, we can create a report that is more detailed and rich information on trading results.

Finding Optimal Value without Optimization (Part 1 of 2)

2010-10-03T21:16:00.006+08:00

When a trading system suffered a drawdown phase, mostly what we do is performing optimization on a few variables to make adjustment to market condition. I do not want to debate whether the optimization will guarantee profitability or not. But one thing is for sure, do the optimization would take its own time in making trading system. But depending on a trading system that we make, sometimes there are some variables that we can actually know their optimal value without performing optimization.
In recent months I forced myself to complete an EA who worked on the USDJPY pair. This is based on several requests from my friends who came from Japan, and in general most of the visitors of this blog in recent months came from Japan.
I also get some input on the settings used on my EA, both vs_eurocross or on vs_eurchf. Actually I was a little worried about seeing their courage to use my EA on USDJPY pair, especially if they use vs_eurocross. But despite it all, what my concern is how they do the optimization in several variables, especially the trading time.
Finally I got the idea to create a function that analyzes the trading results as a whole when we make the process of backtesting. I think this should be better if the developer of MetaTrader include this report in a detailed statement. What I want from MetaTrader developer, as appropriate, we can get a detailed statement of profit / loss based on the hours or days. Isn't it interesting one?
Now to see how the script / functions work, I insert this function in the EA that I have just created. Then the functions / scripts will work right when EA completes an backtest. Or in other words, this function will be called from deinit functions in MQL4. As an experiment, I arranged for this EA to work from 19 o'clock until 4 o'clock. I do not want to mention the time zone, but for the record I always use data from Alpari broker. Apart from all the other variables, I do backtest from the period January 2010 to August 2010 and it's equity curve looks like the picture on the following image:
Ah .. I do not think anyone wants to invest his money in the system like this. But maybe the person will change his mind after seeing the optimal value of the trading time that obtained without optimization.

Again a Commercial EA Sell Volatily Scalp Expert Advisor

2009-10-08T15:09:00.003+08:00

A few days ago I received an email containing an attachment of a commercial expert advisor. Ea was named CaspianEA CHF. The sender suggests that the EA is very similar to VS_EuroCross. After watching the entire of Caspian code, then obviously it is a copy of VS_EuroCross.
I must admit it seller is smart to hide his cunning. Unlike the Pip Turbo EA, CaspianEA do some things to hide that EA is just an imitation.
Changing DLL File Name
The first thing done by CaspianEA to deceive buyers is to replace Volatily Dll file be CaspianEA.CHF name. This is not a difficult thing to change the name because I also recommend if you want to run vs_eurocross on several pairs in a terminal. But look at the function used, it is clear that the version used is version before d05. But fortunately they can not change the name of the function names are used. So they actually just change the file name. And so far, although I've sold some vs_eurocross source, but for the DLL source code itself, I never give it to someone.
Changing Volatily Period Variable with Caspian Factor
This is just a trick. In principle, this variable is the period of the Moving Average, Standard Deviation and Average True Range Indicator. CaspianEA using a smaller value such as 3. However, in the code, this value will be multiplied by 10. So to use volatily period = 20, then the value Caspian Factor must use 2.
Putting indicators that are not used in any trading decisions
This is exactly the trick that fooled many traders, especially for those who do not understand the MQL language. EA sellers will say they add some indicators. But in fact, their EA does not use these indicators in any trading decisions.

Volatily Scalp, USDJPY Expert Advisor

2009-09-15T23:41:00.004+08:00

This is the result of optimization that I did on USDJPY pair using VS_EURCHF_D01 or Pipturbo EA. When I published Volatily Scalp EA, this pair is not included in my recommendation. I prefer to the USDCAD pair, because it backtest results from the period 2004 until February 2009 gives better result.
What's interesting about this backtest results are not used daily filter. So I set the MaxDayAtr to the greater value. I also let TradeLowRangeDay and TradeOutSideBand value with True. However, it has a limited trading time. EA will only work in 22-23 GMT +2. But in practice, based on the logic contained in EA, this means that EA work at 22-0 GMT +2. So don’t expect a lot of number of trades will be executed. And unfortunately, this is just a short back test period, which begins January 2008 until February 2009.

Variations of the Period, Entry and Exit

2009-09-14T23:28:00.005+08:00

So far, all Volatily Scalp EA that I created is using the Moving Average as a target for the exit. In vs_eurchf and vs_eurocross I use 20 Period Moving Average while vs_eurgbp I use 50 Period Moving Average. This system will provide maximum results if the price moves only among the Upper / Lower channel and Moving Average ..
Actually, with 20 Period Moving average, we could impose the use of Upper / Lower channel as the exit. But unfortunately, it is very often if we wait for prices to penetrate Upper / lower channel, instead of profit that would come less. So when doing testing, I found an exit on the moving average is more profitable than the exit on the Upper / Lower of Keltner Channel.
10 Period Moving Average
This is slightly different if we use a shorter period, in this case 10 Period Moving Average. With a shorter period, this will increase the sensitivity of the moving average. This allows us to no longer put the Moving Average as a place of exit. However, the place for entry can be used as the exit for the opposite position.
I found the use of a shorter period would be very beneficial if used in the major pair. This is what I try to apply on USDCAD pair. Especially since I only use the shorter trading time (22-23) GMT +2, so I think it is wise to maximize the profit from each trade.
Combinations 10 and 20 Period Moving Average
Actually I was a bit hesitant to use this combination. For the first time I tried to use 2 Keltner Channels Indicator simultaneously. This provides 2 variations to place the entry.
The first variation, entry can be done if the price penetrates both Upper / Lower channel. To exit, we have 3 places, 10 Period Moving Average, Upper / Lower of Keltner Channel (10.1) and 20 period Moving Average.
The second variation, entry can be done if the price through the channel up / down Keltner Channel (10.1) while the distance between price and 20 Period Moving Averages is greater than 10 Period ATR. For the exit we can use as the first variation.
This method I use to pair USDCHF and USDJPY and You can see the back test results on my previous post.

Trading results, is there a dependency present?

2009-09-13T22:38:00.004+08:00

This week begins with the loss derived from Eurgpb pair. But in the end these losses can be covered and still make a profit, although not as the previous week. The question whether any good results will be followed by the opposite result?
Apart from that, EA's performance was good overall, including new EA that run on USDCAD this week.
Determining Lot size
Along with the increasing number of pairs that use, the determination of risk for each pair and the EA becomes a problem. For the moment I tend to use fixed lot for EA that run on the major pairs. As for cross pair I use a fixed ratio. But from my observation, it is rarely a pair makes big profits for 2 successive days. Exceptions occur in 2 weeks ago in which a constant EURGBP pair produce a better profit than the other pair. But generally, every day the pair will produce more profit will be different.
Change lot size every day based on the performance of previous day might be an interesting idea. Since I tried VS_EurChf these characteristics have become my thought.
At the end, maybe we should learn about the z score, a statistical method to determine if there are dependencies or correlation among all our trades.

Breakout System

2009-09-07T22:38:00.005+08:00

I want to share about breakout technique which I am trying to do, so can be used as automatic trading or EA. Maybe coincidence or not, what I'm talking about here has been discussed elsewhere either in private or open in somewhere. And anyway, the contents of this post is not intended as recommendation to your daily trading. But at least this may be useful for traders who have similar interests to explore technical breakout.
Breakout Problem
A common problem encountered in making the trend following system is to avoid what is often called a whipsaw. If the entry technique is using a breakout system, the main problem of course is a false breakout. Even today generally it is easier and more common system against the entire breakout, like all of EA I share here.
Generally, to avoid the whipsaw, the developers of trading system to add various kinds of indicators that serves as a filter. For trend filter, a commonly used indicators such as the Average Directional Movement Index or ADX. Besides, the used period and Time Frame is also determining the number of whipsaw. The shorter the period and Time Frame that we used the more whipsaw, and vice versa.
There is also a breakout system developed using the European session as a filter. And as I recall one of popular EA that using this technique is Hans123. In this case it use a trading time as a filter instead of mathematical indicator.
King Keltner Strategy
Chester Keltner introduces King Keltner trading system in 1960. Chester Keltner creates a channel based on MovingAverage and added / subtracted with the Average True Range as an upper and lower channel. Specify a period of Moving Average and Average True Range. To create an Upper Channel, you add the Moving Average value with the Average True Range. To create Lower Channel subtracts the value of moving averages with the Average True Range.
This system is very simple, a buy signal occurs when prices penetrate the upper channel and sell signal occurs when prices penetrate the lower channel. Even with optimization, it is possible to make a stop Reversal System. But in general with this system, we will close all positions when prices turned back into Moving Average. One possible variation is the close only breakout. The buy and sell signals occur if the price closed above/below the channel.
Become an Automatic Trading System
With no specific rule to use the same period between the Moving Average and Average True Range, we can perform optimization on both these variables. Also we can try to optimize the deviation that we use. To reduce whipsaw, can be added ADX, and is also can be optimized. But as I said from the beginning I was not going to make this EA. Anyway you can search for this EA on the Internet; I think many are available for free.
This is just an introduction; in the next post I will explain what my observation is.

6% Profit During a Week

2009-09-04T21:24:00.004+08:00

A week has passed and all my EA produces 6% profit from the Initial Balance. Of the total profit is 1 / 3 resulting from EURGBP pair. And pull it constant obtained every day for a week. Maybe if you run Scalping EA on several pairs at once, usually you will find that every day pair producing more profit will be different every day. And I think it was a good thing, because then diversification is working properly.
What about the EURCHF pair? I still think you can rely. It's just that maybe next week it my open time will shift from 19 to 20 GMT+2. This is based on the fact that often at the end of the UK session was already very low volatility and tend to increase until the closing of the American market. In the last week recorded frequently executed trading at 19 GMT +2, it gives a negative result. But I have not thought of to stop it because after all the great profit potential is still there at this hour.
For USDCHF and USDJPY pair I thought I would still use the trading time 22-23 GMT +2. Although the latest optimization shows that both pair can be traded (scalp) until 4 GMT+2. But I think in the medium term will be very volatile. But instead I will add a new pair of USDCAD. Recently I tried to add the VS_EUROCROSS Fractal indicator, and the results are good for USDCAD pair. Thus I will add this pair in my account next week.

A good performance in 3 days

2009-09-02T22:36:00.005+08:00

A good start is in early September. Apart from the losses at the end of last month, eventually most of the loss can be offset by profits earned in the last 3 days. This can not be separated from the good performance of the 2 pair I have just used, the USDCHF and USDJPY.
3 days detailed statement
Also impressive performance was obtained from the EURGBP pair. So that it can be said that the worst results obtained from the EURCHF pair, although still positive in the end.
I give a special note to the EURGBP pair. This pair can be said to not give a meaningful contribution in the last month. But when I noticed lately, EURGBP pair is slightly more volatile than the EURCHF pair. This can be noticed before the closing session of the UK. Even the early Asian session that EURGBP volatility is still possible to get a few pips profit.
This will become more evident if we compare the daily chart for the both pair. For the EURGBP, its ATR (5) is above level 60, while EURCHF is still under level 60.
But maybe that interest is to compare the condition of the daily trend in the both pair. A question whether this is the difference? rd3etifapw

Scalping And Volatility

2009-09-01T21:38:00.004+08:00

I think August is the month that EA is not profitable for me. Right in the last week in August was EA I experienced considerable Drawdown. As a result the loss of 75% of the profits that have been obtained from the beginning of the month.
Perhaps this is the accumulation of the low volatility of current. When the market was in a low volatility, the possibility for a change (increasing) to the greater volatility. Actually I've noticed this situation since the beginning. As the UK towards the end of the session, the market does not show impulsive movement. Finally, Impulsive movements result in the end it started the American session. Fortunately the price corrected more than half, so that greater losses can be avoided.
Shock Trade
I personally hope this is a sign will be a change in Day-to-day volatility of the next. Although not in the short term, at least those changes may be seen in this month. Ideally for scalping system in the Asian session, at least ATR (20) are not under 6. And to achieve that level condition, at least daily range should be above 75 pips.

New Expert Advisor

2009-09-01T20:14:00.005+08:00

I've made an EA. Still incomplete, but at least my backtest results do quite encouraging, at least for the last 1 year. EA is working on the USDCHF pair and just do trading at 22-23 hours GMT +2. Nevertheless my backtest results on USDJPY pair also gives good results although there is a greater drawdown.
New EA
And it turned out with little change in my vs_eurocross can also get a satisfactory result on the both pairs. I change volatility period to 10, and set a maximum trade per position to be 2 and maximum trades per bar to 1. As for the use of indicators ck_speed speed is limited to 1. (Yellow).
VS_eurocross backtest on usdchf
VS_EuroCross on USDJPY
Especially for USDJPY pair, my backtest results using vs_eurchf_d01 or pipturbo, by limiting the trading hours of time at 22-23 GMT +2 also gives good results.
Thus, at this point I added 4 EA and into my account using 3 difference EA.

Finding Best Time to Scalp Major Pair

2009-08-25T21:27:00.005+08:00

I start my job again making trading system for major pair. This system is still working on a particular clock hour. For that I tried to dig up from some other popular EA, see the tendency at any hour they work.
I find generally brief EA is working on a range of time shorter than the EA is working on Cross Pair. This makes the number of trades executed may be very little. This coupled with the fact that they generally only work 4 days a week. The effect recovery factor will be a long time, when the EA suffering draw down.
Interestingly most of the EA is able to work in more than one pair at a time, either by using the same variable or different. Unfortunately one of the fundamental weaknesses that are owned by the Meta Trader is that we can not do backtest on more than one pair. So we can not determine whether it is more profitable or not. Diversification effects may not work properly as expected.
As a preliminary conclusion, I see that most of us will get a good backtest results if we restrict the EA to work on the 21-23 or 20-23 hours GMT +2. This is not foreign to me, because when I make VS_EurCHF, for the pair EURUSD, the profit factor increases if the trading time is limited to 20-1 GMT +2.
I tend to wish to make my EA is able to work as well as with the Cross pair. However, until now, I must admit, that forced to work like that cause suffering Account large draw down. Until now I was thinking to try some exit strategy. With a small amount of trade, should be made to maximize any existing trade instead of just scalp it.

Expert Advisor Performance Hourly

2009-08-19T13:36:00.006+08:00

I think we should be grateful to Mt4stats which has developed a variety of features it has, so we get a better picture of how the performance of an expert advisor. The entire feature is currently not possible we will get in the Meta Trader Detailed Statement. The most concrete example is we can analyze the performance of expert advisor hourly. This is very useful for us to run the expert advisor who works only on at certain hours. Here is current performance on Alpari Russia demo server.

Pips vs Hours

If we consider the graph above, then we will have a picture of what hours on the expert advisors that produce more profit than the other hours. For plasticity at this time that most of the profit obtained on days 18 and 22 (19 and 23 GMT +2). Based on this information, we can see that the open hours for the best at this time are 19 and 23 or 19 and 22(GMT +2). But back at any time that this condition could be changed. However, this is the most close to the current market condition.

Keltner Channel and Bollinger Band

2009-08-17T20:51:00.004+08:00

When I learn about Average True Range and Standard Deviation indicator, I find it interesting when put Keltner Channel and Bollinger Band together on a chart. As we know, that the Keltner Channel is made from a combination of Moving Average and Average True Range. And Bollinger Band is combination of Moving Average and Standard Deviation.
What's interesting my attention when Bollinger Band (20.2) is located inside the Keltner Channel. (20.1). This is a technical condition which is very appropriate to describe the market conditions are in the sideway. Moving Average is located right in the middle chart. Support and resistance are on the right Bollinger Band. Unfortunately, often in a situation like this, the price Range doesn’t allow us to make profitable trades. Especially with the wide spread condition plus the possibility of getting slippage when taking and liquidating a position.
However, the longer market in the situation likes this, and then will be going to the big new trend. Possibility of profit that we get, can be lost quickly when the breakout occurred.

Lose by slippage

2009-08-12T11:11:00.007+08:00

Since the possibility to set the minimum range for executing trade, we must realize that in real live trading we will fight with slippage. Forcing expert adivisor to close profitable trade with just one pip may look amazing in back test result. Unfortunately we can't perform slippage simulation during backtest. Generally each backtest result should be recalculated by reducing all profitable trade with slippage, as well adding losing trades by slippage.
Now let we make backtest using fixed lot. At the end of backtest we could see average profit in pips by converting average profit in money with pips value. How many pips our average profit in pips?
Scalping definition by brokers
Mostly in the Term of Service and Term of Condition every brokers tell about scalping method. Generally its about time and profit. No closing trade before x minutes or no closing trade less then x pips. Violate this rule can cancel all our winning trade and of course not for losing trade. We can still follow this rule however. In the other hand some broker will warn us if we executed xx trades in short period. For this kind of rule, we should consider finding another broker.

Exploiting Low Volatility

2009-08-10T21:26:00.005+08:00

At the decent time most of trades executed during 19-23 GMT+2 only. After that time often just one trade can be executed. With the possibility to set the minimum range we can exploit this low volatility. I change my set for 22-05 trading time. For the last 2 days, I don't use spread filter during this time. I set my min range to 1 and let my min profit to 2.
VS_EurChf Optimization
Actually optimizing VS_EurChf is more simple then vs_eurocross. Mostly you just need to optimize the trading time and stoploss. To get higher profit ratio then reduce maxtrade value. If you are optimizing on Mayor pair then you should always set TradeLowRangeDay to False as well tradeoutsideband. On the other hand, you set both variables to True on cross pair. rd3etifapw
Keep the robustness of your optimization. Every time you get satisfaction result on mayor pair, then test it on other mayor pair and it should be profitable. The result should be also profitable on cross pair.

VS_EuroCross_D05 Update

2009-08-09T19:47:00.014+08:00

I have fixed the wrong statement as my previous post. Now you can update your VS_EuroCross_D05. However it's not including the new FFCAL indicator.
I also expect if your are newbies to Meta Trader platform, then find guidance from other site. Although in the next future i will post about MQL4 programming and EA installation guide. And if you are newbies to use my Expert Advisor, then please read my old post if you don't find any answer in the manual.
My Recent Activities
At the moment I still build the VS_EuroCross without using ActiveX. May be is sound weird, but its true. Since publishing my VS_EuroCross with using ActiveX, I never update it original source, and all my demo test also using what you download from my 4shared folder.
Preparing for Market Change
On my own observation, every year during August to December, the volatility will increase, and often market in trending way. Refer to last year performance, during this period is a heaven for any scalper EA that work in Asian Session. Will be repeated? No one can answer it. However during high volatility my EA will trade often. Thus if this happen reduce your risk, and expect bigger profit from more pips that EA earn instead of increasing your trade size.

Difference formula for buy and sell signal

2009-08-07T23:29:00.010+08:00

There is a single line in my VS_EuroCross_D05 that should be corrected. I forget to link it with the external variable. It make your optimization will not work on long position. However in the short position it work well, as well if your broker offer 3 fixed spread and you use default setting.
It is located on the line 419 setFilter2(currange,3,1,0,0), all these parameter should be linked in the external variable. It is over optimization. Because the entry formula for long position is different with short position. To fix it, just go to the line 398, or find this statement setFilter2(currange,MinRange,MinProfit,UseRange,UseTradeRange) then replace it. This is the correct one. For a system, the Sell signal and Buy signal should be symmetrical.

VS_EuroCross_D05 Will Become The Last Version

2009-08-06T21:29:00.003+08:00

Although the VS_EuroCross_D05 is the last version of VS_EuroCross, but still it has some problems that I can't fix it.
The Trading Time
Unfortunately until now the trading time problem in VS_EuroCross_D05 is not fixed yet. This problem is regarding to the rule no trade in the first 2 hours at weekly opening. In simple world no trade before Monday 0 GMT+0 every weekly opening. Thus if you can't match this rule with your broker, then it is better just avoid trading during this time.
Running more then one VS_EuroCross_d05 in a platform
According to Mq4 reference, that all Dynamic Link Library file is shared to all EA in the platform. Unfortunately this is make VS_EuroCross unstable if your run it on several chart at once. However you can do little trick if you keep going to run it on several charts at your MetaTrader Platform. If you already copy the volatily.dll in your library folder, then simply copy again that file and give it difference name, such as volatily1.dll; Next you need to change the import statement in the mq4 source file. Just find this statement #impor volatily.dll and rename the volatily.dll with volatily1.dll; You can do this step as much as you want. However you have to be wise regarding the performance. You should only do this thing in your demo account.
The FFCal Indicator
Regarding the FFCal version which is included in my package file,please visit fx-knight.com to get the latest version.
Because of scalping is a high cost game, you may need to find such rebate program to minimize your cost. However you may not always get rebate by the Term of Service or Term of Condition from the broker. But the end it would be better to try it.

Entry Setup

2009-08-06T11:42:00.006+08:00

I grab the picture today that showing how VS_EuroCross_D05 trigger the trade with new entry rule (UseTradeRange=true). As common rule in my Volatily Scalp EA that to trigger entry the distance between price and MA must be equal or more then signal filter. The signal filter itself is comparable the maximum between double spread and current 20 Average True Range. Applying this rule will guarantee if price hit the MA at the same bar when it triggered, we will make profit as much as current spread or even more, in case the current ATR is bigger then double spread.
Back to new entry rule, it is now calculate the current range. If the current range is bigger then Signal Filter, the entry will be triggered if the distance between price and MA is equal or bigger then spread + 1 pip. But still it must penetrate upper/lower Keltner Channel. Mostly during low volatility, if the price penetrate upper/lower channel while current range is bigger then double 20 Period ATR, price will back to Moving Average.

Variable Optimization

2009-08-05T19:31:00.009+08:00

What make me enjoy with VS_EuroCross_D05 that it is more profitable with any previous version just using single trade per position. If you would like to optimize this VS_EuroCross_D05, try to optimize the MinRange and MinProfit variable. In this case you should set the SpreadFilter to false. You can apply UseTradeRange and UseRange after finding suitable result, other way you can directly to optimize those variables.
I made 2 back test before releasing VS_EuroCross_D05. The first back test just to set UseTradeRange Variable with True, and the second I set the MinProfit with 2.
UseTradeRange True
MinTarget True

FFCAL Indicator Setup

2009-08-04T14:31:00.002+08:00

Since VS_EuroCross_D05 come with FFCAL Indicator, I add some external variables to use FFCAL Indicator. In VS_EuroCross_D05, the use of FFCAL indicator is integrated in the trading time function. As the news filter, the main thing that you have to do is deciding minutes for news before and after.
Below the list of external variable that you have to set to use FFCAL indicator. However please remember that VS_EuroCross_D05 comes with 2 MQ4 files, VS_EuroCross_D05.Mq4 and VS_EuroCross_D05_NonFFCal.Mq4.
extern bool NewsFilter =false;
It is the first thing that you have to change. Set its value to True to use FFCAL indicator.
extern int MinBeforeNewsCloseAction=15;
Set the minutes before news for closing all open positions. Default value is 15 minutes.
extern int MinBeforeNewsNoTrade=60;
Set the minutes before news to tell expert stop executing any trade.
extern int MinAfterNewsToTrade=120;
Set the minutes after news to allow expert execute a trade.
extern bool IncludeMediumImpact=false;
Including medium impact news or not.
However you can't filter out the news by its Country.

VS_EuroCross_d05 External Variables

2009-08-03T17:20:00.004+08:00

Below the list of new external variables that are used in VS_EuroCross_D05.
extern double MinRange =3
Unlike any previous version, now we can use flexible range (distance from MA) to execute the trade. Inside the code, this value will be added with current spread. Thus this is just equal with double spread (Spread on my backtest is 3).
extern bool SpreadFilter=true
If you want to keep using double spread filter, then just set this variable to True.
extern double MinProfit =1
It doesn't mean if you set this variable with 1, then expert will close any orders with 1 pip profit. But since most profitable trades are closed when price hits MA, then the expert will see this variable when price hit MA. Thus if you pay for commission, set this value with 2.
extern bool UseRange =false
Basically it just calculate current range. Set this value to True. My backtest shows better result by using this filter.
extern bool UseTradeRange=false;
I set this value to True, when posting VS_EuroCross_D05 backtest result. Just compare between with FixedTP, the profit factor is equal but VS_EuroCross_D05 has bigger profit then FixedTP.

VS_EuroCross_D05 Now Available

2009-08-02T22:55:00.006+08:00

Finally, its done. You can download my VS_EuroCross_D05 which is coming without expiration time. This version also including FFCal news indicator that use ForexFactory calendar event. It also back to previous version setting, that VS_EuroCross_D02, except the VisibleTP.
As usual every updating will be followed by new external variable, you will find much more in this version. It is just not because the new FFCal Indicator, but also some internal variable in the previous version become external variable right now. Thus I expect you refer to VS_EuroCross_D03,VS_EuroCross_D04,FixedTP to track the change.
You will find 2 mq4 files in the package, one use FFCal indicator and the other doesn't. It will help you to make backtest, because if you use FFCal in your backtest, may be you will find a huge error message in your journal. It may occur if you make backtest while offline, or the indicator didn't get yet its data from ForexFactory.
Backtest Result
Every Backtest that I post here is using Apari historical data, with spread condition is 3. Mostly I use January 01, 2007 as beginning period and February, 2009 as ending period. However you can visit Vrtrader blog, that provide backtest result year by year since 1999, and thanks for his great job.
Anyway I will provide any new variable in the next post, and hope you can test it by your self at the moment. Also please read in the source code, I give some notes for your guidance for optimization.

VS_EuroCross_D05 Available on August 2, 2009

2009-07-31T17:52:00.015+08:00

I have to apologize because you have to wait until August 2, 2009 for downloading VS_EuroCross_D05. I just finished to build this version, but still little modification is needed. However I have already made backtest, and you can compare with my previous backtest. It is same result with FixedTP version. Only there is a significant difference with previous version, at this version I use spread + n pips formula instead of double spread, and the last it become external variable.
This change make incompatibility with any previous mql version. But seem it still possible to make flexibility using spread + n pips formula or double spread.

VS_EuroCross_D05 will be available before August

2009-07-28T21:58:00.003+08:00

I have lose my latest work, but seem I can start again and complete it before August. However if I fail to complete this version, then the FixedTP version become VS_EuroCross_D05 just it will come without time expiration.

How to Choose a Broker

2009-07-22T18:20:00.004+08:00

I run my demo again today rd3etifapw. I decide to use NordMarkets to run VS_EuroCross (FixedTP). I use the same setting with my previous forward test on Tadawul. There is a significant difference in EurGbp Spread at NordMarkets. It offer 2 fixed pip spread.
It doesn't mean i give a recomendation to use this broker to run my EA. Its only cause I see that seem it price movement close to real feed.
However if you are looking for a good broker to run my EA, then just look their liquidity in the Asian Session. Compare several broker real feed, your first attention to find the highest true range (20 Period ATR). Mostly you will find the broker with 5 digits has higher range then 4 digit broker. Next look their spread. Its good if you can find a fixed spread broker that their spread is less then 5.
ECN Broker
It seem a hard one to find low fixed spread broker and looking ECN broker is the best one. ECN offer floating spread (low) according to market liquidity and mostly give another transaction cost. Thus we pay for commission and spread. If you decide to use ECN broker then make sure their commission is less then 1 pip value per trade size. This is important because my EA calculates the profit in pip. I ever find a broker with really good feed and execution. It has higher liquidity then others broker during trading time. But I forget to calculate their stupid commission. Its equal to 5 pip! Sick. My EA can make 7 positive transactions, but all become negative, because it just 4 pips profit per trade.
Requote
Requote is another aspect that you must think before using a broker. Unfortunately we must trade in real to know it. There is no other way to know how good their execution except to test it directly.

I Stop My Test

2009-07-21T19:29:00.012+08:00

I already stop my forward test on TadawulFX. The data feed on EurGbp is very difference with actual price and unacceptable. However it show us the useful of showing our target. But if you want to compare between your demo on other broker with Tadawul, then here the login 999333047 and password bxr3kqr of demo account.
I run 3 vs_eurocross on this demo account, 2 on EURCHF pair and the rest on EURGBP. Since last week I use the FixedTP version.
Set 1:EURCHF
OpenHour=19;
CloseHour=23;
Risk=25;
UseAtrMod=true;
MyOwnTarget=5;
VisibleTP=True;

Set 2:EURCHF
OpenHour=22;
CloseHour=05;
Risk=25;
UseAtrMod=true;
MyOwnTarget=5;
VisibleTP=True;

set 3: EURGBP
OpenHour=19;
CloseHour=23;
Risk=25;
UseAtrMod=true;
MyOwnTarget=5;
VisibleTP=True;

Others setting is default for all sets. Trading hour is GMT+2.

A week before updating

2009-07-20T22:25:00.003+08:00

As I have stated before that the next version (D05) will be unlimited one, and may be in the short period there is no more any change after that. The version will be release as usual on 27 July or before 1s August 2009.
The FixedTP version is the base of D05 version. Also as I stated before about possibility to use new Indicator, but seem i will not use it the next version. Right now i just think to add news filter because this task is always appear every month.
About Selling My Source Code
I think there is a misunderstanding regarding this issue. It seem i will force you to buy (donate) to get the next version. No, absolutely its a wrong perception. In fact I will release D05 without time expiration as usual in previous version.
What I sell is my VS_EUROCROSS without using activex file. I give you a choice to use unexpired VS_EuroCross with activex version, or to buy the source vs_eurocross without using dll. GPL license will guarantee you can modify my source and resell it, but you have also give your source to your buyer. Term Free is the freedom to get and modify the source code. Other wise you can modify and never sharing your modification if you don't want to share your source.
Anyway if you have another option then you can also contact me to see if we can make agreement.

VS_EuroCross_D05 will be unlimited

2009-07-19T20:18:00.009+08:00

After more then 4 months forward testing, may be the next release of my VS_EUROCROSS will be unlimited version. I will stop for a while any improvement of this version. As exchanged I will finish my others EA or begin migrating this version to another platform, such as Dukascopy.
I Will Sell The (MQL4) Source of VS_EUROCROSS
I have stated in my VS_EurChf that my main business is selling the source code. I just shared the compiled version of my EA with or without time expiration and expecting donation from your profit that made by my EA. May be this is my general answer for all who ever asking me about sharing the mql4 version instead of using the Activex. It make me more confidence to state selling source code instead of saying selling Expert Advisor.
If you can accept the GPL licenses and want to pay for 500$ to get the copy, I will wait a minimum 100 offers before accepting all your offers. Thus mail me at volatily@gmail.com if you want to purchase it, and do not send any money to my PayPal account before i give you notification to send your payment.
Perhaps from this income can improve this blog, and may be next time all forward test in this blog will use real account, and therefore will give more confidence before using my EA in your real account.
However if you use my Activex version, i still expecting donation if you made profit as my general term in sharing my EA.

Redownload My FixedTP Version

2009-07-16T21:18:00.004+08:00

There are two wrong statement in the previous:
double sf=MathMax(sf,arratr[0]/mypoint);//line 751
It should be double sf=MathMax(sp,arratr[0]/mypoint);

isModBuy=OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice()+StopLoss*mypoint,GetOptimalTP(Magic,OP_SELL),0,Red);//line 797

It should be:
isModSell=OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice()+StopLoss*mypoint,GetOptimalTP(Magic,OP_SELL),0,Red);//line 797

Best Performance

2009-07-16T11:46:00.005+08:00

I think this is the best performance from VS_EUROCROSS since d01.

Showing The Target (New Update)

2009-07-15T11:34:00.005+08:00

I add another feature to VS_EUROCROSS that allowing EA to show its target. On my experience during last two weeks, it seems the Expert suffered too much slippage. This is especially when Expert holds more then 1 positions and tries to close all position at once.
What I see if price make up down move within 6 pips will make EA react and often EA will get requote. After make several test finally I can add this feature to VS_EUROCROSS without affecting all the exit rules.
POSSIBLE PROBLEM IN LIVE TRADE
Although backtest show there is no much difference when using fixed target (I am not sure but its looked better), but something difference may occur in live trade. All broker can rise their stoplevel and if the stoplevel become the highest then our signal filter or MyOwnTarget, then the target become meaningless. But still it is useful when somehow you loose connection to your Server. Although it is possible to tell EA to set the target every tick or bar, but I decide to let EA doing this thing just when new position is taken. But still the EA will force to give fixed target when it failed in the first attempt. Therefore each position will has difference fixed target.
Another possible problem is the freeze level. This is happened when the expert tries to close an open position while its target is very close with market’s price.
To disabled this feature, then you can set the VISIBLETP variable with FALSE, because I let the default value with TRUE.
You can see my MT4stats; the trades on EURGBP have a fixed target and one of them get hit.
Showing the Target

May be I Will Add New Indicator

2009-07-13T20:17:00.004+08:00

I get an indicator that may be i will use it in all my Volatily Scalp EA. Actually I have tested this indicator at the same time with ATR Mod indicator. But i decide not including this indicator in VS_EUROCROSS_D04 and only introducing the use of ATR Mod indicator.
If using ATR Mod tend to trade earlier, in the other hand using this indicator will make our trades will be triggered later. Probably by using this indicator will reduce the dependency of making averaging. But its still earlier to take conclusion because i still make some backtest before deciding to use it or not.

The Idea Behind VS_EURCHF

2009-07-08T19:50:00.006+08:00

I try to trace back my VS_EURCHF_D01source including any note during developing this EA. One you should know, that my first time I made Volatily-Scalp EA to trade EURUSD pair. And VS_EURCHF_D01 is an improvement of Volatily-Scalp General Version.
Early I don't use Keltner Channel, but I use an envelop indicator. I switch from using fixed envelop to use Keltner channel because it has a flexibility to switch to any time frame.
But i get surprised when I test it on several pair, it can make profit without any modification in the code. You can see the screenshot on the manual. But the best result is coming from EURCHF, and for this reason i give the version name VS_EURCHF_d01. And because during developing this EA, the spread on Cross pair is widen, I get the idea to use double spread filter as minimum range to execute a trade. First time I don't use this filter because on EURUSD pair spread is not a problem.
I have compare 3 source, PIPTURBO, VS_EURCHF_D01 crack, and I think the link above is the source that I compiled in VS_EURCHF_D01 package file.

PIPTURBO, SELLING FREE EXPERT ADVISOR TO PUBLIC

2009-07-07T18:59:00.005+08:00

I receive an email from someone who sell PIPTURBO. Here said in his email:

I am the one selling Pipturbo. Unfortunately it seems an incident has come up, please let me clarify and offer you some gratification.

I paid an EA developer to build me a solid EA that could backtest and forward test well on atleast 5 popular currency pairs. I wanted it to have lots of features and customization opportunity. Well, what he gave me seems to have been either sourced extremely well off your ea VS_EURCHF or he basically just copied it and changed a few things here and there.

Regardless, it is clearly a big mistake and I am trying to get a hold of the guy that did this to me, but so far no answer from him.

But I am willing to offer you a donation in exchange for selling this slightly modified version of your EA and removing all negative posts about Pipturbo being a clone.

If you agree, I would be willing to donate you $xxx.

Again, I apologize for this, I should have done better background checks before hiring someone to do this kind of work. I hope we can make an agreement about this.

My answer, "I am sorry we can't make that agreement".

I receive donation and letting people buy that something they can get it for free? No thanks. You don't have to apologize. But let people know what PIPTURBO is.

PIPTURBO, IS A CLONING OF VS_EURCHF_D01 ?

2009-07-05T21:15:00.002+08:00

A new commercial Expert Advisor is releasing during this week and its name PIPTURBO. It is really new, because when I visit their official site and there is nothing out there except their home page. But I find something an interesting when I visited a site that reviews about PIPTURBO http://forex-naked-truth.com/pipturbo_review.html. Here is their statement:

PipTurbo also offers many trading filters that will prevent the ea from trading if certain conditions are or are not met. Some of these are very important and most users will wish they were implemented in ever EA they try.
Time Based Filters:
- Because most of the conditions occur at the closing of American’s Market to Asian’s Session, PipTurbo will include a Time Based Filter.
- Trade time only 21-0 GMT general for all pair. A larger time frame can be used like 21-4 but backtests will show fewer losses if kept at the 21-0 timeframe.
- No trades during the first 2 hours on Mondays. Many surprise moves here.
- No trades on Friday after 8 GMT.
- No trades from 20th of December to the end of the first week of the new year as this is one of the worst periods to trade.

Daily filters:
- No trades if the previous Daily close was above/below 2 deviations of Bollinger Bands.
You can avoid this rule to set TradeOutSideBand’s value to TRUE.
- No trades if current 5 Period of Daily Chart showing above MaxDayAtr.
- No trades if the previous days range is too low. Too low is defined as (yesterday high – yesterday low) is less than the current 5 day ATR. You can avoid this rule by setting TradeLowRangeDay value to TRUE.

I don’t mind if they create this expert from the scratch. It’s possible because all VS_EURCHF logic is explained in the manual. If really they make it from the scratch, and state that it is an EA that base on VS_EURCHF manual, then I am glad to recommend any my visitor to buy this Expert as an improvement of VS_EURCHF. But it’s sad if they just crack any free ea, repackage and then sell it to public.

Trade in the right time and the right size

2009-07-03T22:03:00.003+08:00

Since d04 I make forward test with 2 instances of VS_Eurocross on EUR/CHF pair with difference time trading set. It is just another way to optimize my system instead of changing any possible variable. I still try to build a version that can run with several time set at once with difference risk, Money Management and maximum trade. What the lack of Meta Trader platform that we can perform a back test with more then 1 system in single account. So we must combine all system in a single EA to perform such test.
Perhaps by doing this test, it can help us to decide when to put our risk at maximum value, and when we must trade with low risk. Putting risk on the right size is not easy task. Although there are some money management strategy but not every system can match with those formulas.
I post the trades of the trading from last night and seem if trading time 19-05 is worse in this case, it hold trade longer and get less pip.
Open Hour 19
Open Hour 22
On both picture you see also why I am not recomending to run more then 1 expert at a terminal. You can see the spike, once expert can get 2 trades while the other just a single trade. No matter how good your PC and the realibility of your internet connectivity, all expert advisor that run in a terminal, is executed in a single Thread. You can search in google what the term of Thread meaning in programming. But what I know that if an EA is executing its order, then the other's expert on the same terminal must wait to execute their order.

VS_EUROCROSS_D04 Now Available

2009-06-28T23:16:00.004+08:00

A month has been passed, and it is time for VS_EUROCROSS_D04. Again there is no any change in the main system, except adding expiration as usual. But since this version I decide to allow the EA using built in ATR or custom ATR. And other thing it is now using ECN style.
There are new External Variables in this version:
int Margin = 100;
This is Money Management feature that allow you to set the percentage of your balance in case you run several EA at the same time. For example if you have 10 K in your balance, you can tell the EA just to use 20 percent from your balance before calculating the risk.
Bool UseAtrMod = false;
This is the variable that you have to try. If you set it false then it just like previous version. But make sure you use the historical data from your broker before testing this variable.

As my last post before, I try to optimize this EA to work earlier then its default trading time. What the setting that I use with D03 version in the backtest are:
OpenHour=19;
CloseHour=23;
UseAtrMod=true;
MyOwnTarget=5;

IMPROVING VS_EUROCROSS

2009-06-27T21:21:00.003+08:00

I make a lot experiment during this week with VS_EUROCROSS before updating its expiration time. I try to change the Simple Moving Average with another MA type such as Exponential MA and Linear Weighted MA for building Keltner Channel Indicator. I also change the Average True Range calculation by using same averaging method. Thus I have Keltner Channel indicator with more flexibility in averaging mode. I put both indicators in the same chart and you can see the difference even with the new Indicator I use Simple Moving Average to calculate the Average True Range. The blue channel is 20 period Keltner Channel using customs ATR.
BUILT IN INDICATOR VERSUS CUSTOM INDICATOR

This chart is using Tadawul platform. If we look the chart should be more trade if we use new Keltner Channel Indicator then previous one. In Alpari, using this new Indicator doesn’t make any improvement (worse) with default trading time. But if I change trading time with open Hour 19 and close Hour 23, Using VS_EUROCROSS_D03 you can see the result.

VS_EUROCROSS_D03 with custom ATR
But it is still worse. Because my experiment it made more profit with less trades.
Less trades with bigger profit
And with same setting on EurGbp
Perhaps next time we can have 2 trading time set and give difference risk, other thing that mostly spread during 19-23 time is still low.

Profit Calculation

2009-06-18T18:45:00.007+08:00

I make backtest today since I don't run my demo, and find something that I can't explain why it can be happened even in the back test. At the first time I guess that maybe there is something wrong, and then using my MQL version, I made back test in visual mode, and tell EA to show current pip profit in chart window.This is just calling my TotalProfit function in MQL4.
Take a look at the left corner, even price at 1.5063/5066, but the total profit (pip) is 0.

Let see the last 3 trades. The first trade is executed at 1.5067. Then the second trade is triggered at 1.5075. The second trade is closed at 1.5069 and made profit about 6 pips (as much current ATR). The first trade still in the market until the third trade is triggered at 1.5077. When price (ask) hit 1.5071 (at this point our sum profit from 2 orders is 1, 1.5077-1.5071=5 and 1.5067-1.5071= -4), the EA close the profitable trade (3rd trade) and made profit 5 pips.
Unfortunately, when price (ask) hit 1.5066 the total profit (pip) that EA record is 0. And the EA didn’t close the first trade, then there is a spike after this, and hit 1st trade stop loss.
Correct
I don’t know if it also happened at live trade not just in the back test. At the other picture the EA show current profit calculation correctly.

I try to close with 0 pips profit at this point by changing the target, and then I get slippage 2 pips. The order is closed at 1.5065/1.5068.
Slippage

What I can say, this is always happen in our real trade. If you watch your trade carefully, then you may find sometimes your profit doesn’t change while market has been move for a pip.

2 Hours Delay on Weekly Opening

2009-06-15T15:31:00.004+08:00

I still don’t know how to react about difference opening time for each broker. Since my work using Alpari historical and I never test it with other Broker’s data. So far on forward test in Tadawul give good result if the expert trade in the first hour, but I don’t know how the performance in the past. There is no special exit strategy for any trade during this time. It’s fine if our trade become profitable during this hour too. How if it doesn’t make profit? This is important because the EA will enter to non trading time, and the EA never find this case in the back test.
Managing Your Risk
Although it is not covered in my EA, but truly there is a difference in potential gain in the first trade. Normally after trending market in American season the first trade tend to be above 2nd deviation Keltner Channel or even more. It is not always happened at 20 (GMT), it may be later. But the point is our potential profit will be higher. You can make a back test, and you will find that the higher profit almost in the first trade.
And if we look to back test result, during 20-22 (GMT) trading time is the most profitable area. This is not meaning that we never getting loss during this time, but this is because our profit during this time is bigger then after 22 GMT. It is because the ATR value is still high during this time.
What an idea that may we apply in this situation is optimizing our Money Management. We can set our MM to give more risk during bigger profit time or trade, and start reducing our risk after that.

Working with Slippage

2009-06-09T21:17:00.001+08:00

I try to optimize the closing trade function by forcing to close our trades with our price. What I do is checking the last known market price before sending to closing trade function. So the EA will always compare our last known price with current market price.
If the EA wants to close Long position than it must be happen if current price is higher or equal with the last known market price and vice versa. The expert will force to complete this action before new bar is coming. Once new bar is coming then the EA will wait an others logic for closing trade.
It might to be a compromise decision, because we have to decide to allow EA working with its logic at any price (no matter slippage), or forcing EA to close with exact price while allowing another logic to be waiting (back test will be differ after live trade).

Tight Stop

2009-06-03T12:42:00.003+08:00

I think you have to know my idea behind using 60 pips stoploss, what a huge stoploss for scalper system. I aggree with tight stop, but actually there is a danger behind using tight stop on my system. The 20 period of CK_Speed Indicators is a lag indicator. And color changing in this indicator is very depending on current market Volatility. The color changing is not coming from a fixed value.
Therefore if You use tight stop may be you will find the expert keep going opening trade just after your stop was hit, because the indicator is still allowing to trade.
I use 60 pip stoploss because backtest showing that this value is enough to protect EA to make continues trade and finding suitable price before doing cutloss.
Right know Only VS_EURGB that has ability to protect itself doing continues trade. I just suggest that You should have a plan about this condition. Market volatility can change in any time. I think you should test your stop in high volatility period. You can test it during August-December 2008, because during this period most pairs record it's higher volatility since they traded. And surprisingly, this period is the most profitable period for all scalper system that work during Asian Session only, even with wide spread.

Introducing My VS_EURGBP

2009-06-02T01:19:00.004+08:00

Personally I have tried several method to scalp this pair, but the end I realize that the most working idea is just the trading time. I just use 20 period WPR to trigger the entry and make sure the distance between current price and MA (50) is not less then N + Spread where N can be our minimum target. Of course in fact our trade could be placed higher/lower because it must executed while WPR showing Overbought/Oversold value.
The last filter is 50 Period CK_Speed indicator,same period with MA. You can test to use any other indicator, but may be you can start without using any indicator, and show the result.

Here are the list of external variables that EA use, mostly it has the same variables with EUROCROSS Version, except the list below:

To protect us going to deep hole we can tell the EA to stop working and close any open position
extern int NumberOfLoss =2;
extern bool TradeAfterLoss=false;
extern bool CloseAllPositionAfterLoss=true;

extern bool Turbo=falseThis is usefull if you set your MaxTradePerPosition = 4.
extern bool ContinuesTrade=false Not repeating same trade that make a loss.

extern int MaDinstance=2; Try Optimize this value

Mostly the list variable below is working if MaxTradePerPosition is 4
extern int AveragingStyle=0;
extern int SpreadMultiplyer=1;
extern int FixedAveraging=6;
extern int AtrPeriod=5;

VS_EUROCROSS_D03 Now Available

2009-05-27T16:16:00.003+08:00

I just updated the expiration date for this release (July, 05 2009). The new fiture only allowing EA to disable hedge ability, following American regulation. Also fixing a bug in MQL4 (Thanks to Max). You dont have to change the ck_speed indicator.
About security, make sure you scan the Activex file, and please remember it will never prompt you to enter anything and will not make connection to any address. This expert will work without any activation.

VS_EURGBP DONE

2009-05-24T19:19:00.002+08:00

I am not really sure you are interesting with this version. There are a lot of popular EA that scalp this pair at Asian session. And the most probably reason, that spread in this pair is higher during Asian session.
Actually if you see my MT4 stat, I am not using VS_EUROCROSS to trade EURGBP. It my uncomplete VS_EURGBP execute that trades.
But seem I stil need for a week to build the Activex, perhaps it will be available at the same time with VS_EUROCROS expiration update.

Back test Problem

2009-05-19T15:15:00.001+08:00

So far the common problem that rises when doing back test is digit difference between brokers. But the fact that I never find that problem when running in mode even real account. However I realize that the closing function in the expert is not normalized as it must. Therefore I make an update of MQL to solve this problem. But again if you make backtesting then historical data should come from the related broker or the backtesting become meaningless when using different broker with different data.
Although I give a code “4digits” in the file’s name, but it does not mean it can’t work with 5 digit broker. The difference between previous update, that this update normalize all closing function with broker’s digit. Therefore I am still keeping the previous update, if current update can fix digit problem then I will delete the previous one.

What new in the latest update (5-17-2009)

2009-05-17T18:56:00.003+08:00

I try to solve some problems that rise when using this expert on different brokers.
Fixing error number 131, this is Order Send Error caused by invalid trade volume size. This is happened on broker that their Lot Step others than 0.1 or 0.001.
Add new external variable Monday Start. You should give this value buy adding your Open Hour variable with 2.
Add sound alert. Yeah, the expert will play alert.mid when it open a trade.

VS_EURGBP 90% COMPLETE

2009-05-03T23:14:00.003+08:00

There is a different between this version and previous one. I decide to design this version for working on 5 Minutes time frame. There is a promising back testing result using spread 3, and perhaps until 5. Actually I want to apply correlation indicator, and see the difference. But it needs synchronizing 3 historical pair’s data at the same time. And it makes slower back testing. And even last time I try to download GBPUSD historical data at Alpari server, it’s unavailable. I hope this version available this month, it still need some exit strategies and may be a filter for better improvements.

Time Frame Problem

2009-05-03T22:03:00.003+08:00

For several days I make stress testing to VS_EUROCROSS_D02 to catch any potential bug. I run VS_EUROCROSS_D02 on 5 pairs at a terminal. It seems working well as long all EA run in the same time frame (15 minutes).
But there is a problem when the EA is running then I change the time frame. After changing the time frame, the EA will not work well. Therefore I keep suggesting running one expert each terminal and not changing the time frame. If you change the timeframe, then you should restart your terminal.
If you still want to run 2 EA on a terminal, then use the same time frame.
Time Trading Problem
By default the expert will work from 22-5 GMT. Actually this is related to Alpari UK server time. No matter if Alpari apply DST policy, then this time trading should not change.
To remove the ambiguity I take the Sunday opening as zero hour. Now you can match your trading time by following this rule. Mark your broker’s opening time at Sunday, and then subtract with 2, and this is your Open Hour. The difference between Open Hour and Close Hour is 7.
There is a problem if your broker has not the same time with Alpari server. There is a filter “No Trade at first 2 hour on Sunday”. You can solve this problem by changing MQL code. Just find the statement

if (DayOfWeek()==1&&Hour()<2)TradingTime=0;.

If you have match your trading time, then just change number

2

by adding your Open Hour with 4.
NormalSpread Variable
Basically I use this variable to simulate whenever the Market Spread is changing. Do a back testing on EurChf and change this variable with 4. You will see at the end of your back test, the number of trade will reduce dramatically (if current spread is 3). Therefore if you run this EA in demo account or real account, if current spread is 4, and you keep the NormalSpread is 3, it’s mean the EA work under 5 spread condition. To make EA work with current spread condition set NormalSpread Variable equal to current market spread or give a big number such as 100 and let EA work no matter with spread.

Correlation Indicator

2009-05-02T17:45:00.003+08:00

Another popular method to scalp cross pair is using correlation technique. I get some suggestion to use correlation indicator to improve my EA performance. But first I have to make correlation indicator that match with my system.
And I get idea to make correlation indicator based on market volatility. The main principle of this indicator to compare the mayor pairs volatility. And therefore the formula that I use is so simple. Take the difference between current price and Moving Average of Median Price and then divide by current ATR.
The Indicator has 2 input variables for Mayor Pair that will be measured. By default it will measure the EURUSD and USDCHF pair. These pair should form a negative correlation that if EURUSD showing a positive number then USDCHF should show negative number. This is will be formed by two lines that make us easy seeing the correlation.
The histogram is the difference (absolute value) between both lines. I have tested to change CK_Speed indicator in VS_EURCHF, and showing better result, however the result on VS_EUROCROSS is worst then using CK_Speed indicator.

Create Your Own Exit Strategy

2009-04-29T15:38:00.002+08:00

As any other non stop reversal systems, creating exit strategies become a hardest part in developing trading system. Since I include the MQL4 source code in VS_Eurocross_d02 version, then you can analyze its exit logic. And it is possible to change all exit logic with your own. If you are doing back test; take a look to your journal at the end of back test. You will see a message like "case1:10","case2:10". Each represents the logic code and the total of that exit logic executed during back test period. And you can optimize it by trying to remove it one by one to see the different.
You can have different strategies, but here what I did:
I separate my exit strategies by its working time.
Its mean that I have exit logic that work during trading time, after trading time and work all around the time. If you have exit logic, try to put them on the correct working time.
Create exit strategies related to Keltner channel position
Think if price across the moving average, can it touch next channel? It’s no problem if we make profit at this point, but how if we are holding a loosing trade?
For me, it’s all a guessing game, but using one ore more indicators we can make accurate decision.
Using Profit Accumulation
You will find that sometimes I let each open position to get its target and sometimes I will accumulate the profit from all open position.
Bar counting method
I have assuming that if several bar has been passed and the open trade does not hit it’s maximum target, then try to reduce the target related how much bar it has been passed.

VS_EUROCROSS_D02 Now Available

2009-04-27T02:32:00.005+08:00

Finally you can try VS_EUROCROSS_D02 It is more customizable than previous. Even now I include the MQ4 source, and I have put several function that ready to use to make exit strategy.
New External Variable
VolatilyPeriod
Basically Volatily Scalp system use Average True Range, Moving Average and Standard Deviation Indicator. All these indicators must use same period. By these indicators, construct other indicators that CK_Speed and Keltner channel. Therefore it’s impossible to construct Keltner channel using different period between moving average and ATR under this system. And by nature will eliminate us over optimization that only fixing historical data. Therefore I only put one external variable called “VolatilyPeriod”. By default the value is 20, but you may try another value.
MyOwnTarget
What another strategy in this EA, that we can have another target that may override volatility target at several condition. I suggest using 10 for EurChf pair and 7 for EurGbp pair.
IsTrailing
Set this value to True, the EA will trail our stop loss if the price penetrates first deviation of Keltner channel while 5 periods CK_Speed indicator color is green. Set the value to False if you want to keep your current stop loss.
Performance Issues
I suggest running only one EA at terminal. This is to increase the performance, and will reduce “Trade Context is Busy” Message in the journal.

BUG

2009-04-23T15:54:00.005+08:00

It's Bug
There is a bug in my VS_EUROCROSS Expert Advisor. The bug is in MQL, not in dynamic library. I am checking my trading statement, for last two days, and clearly there is a bug in my code.
But I have fixed the bug. The Expert should not close any unprofitable trade which just opened below 60 minutes and especially still in trading time. You can check my statement report; there are trades that closed suffering -5 pips. That’s true there is a rule in my exit strategies to close unprofitable trade, but not in this case. In technical my fault is declaring local variable with the same name Global Variable which is declared before.
I make back testing for the same period and there is little change in result. With a bug in MQL code, the back test result gives higher result, but with fixing the bug it’s increasing profit factor with less drawdown.
On the first time fixing this bug, I expect that it can cover the missing trades in original version. Seem I expecting too much. It does not solve the problem for the missing trades. But I am satisfaction with current result especially with EurChf pair. With EurGbp pair it has a loosing trade, but seems it can be covered in a month.
I hope your patient waiting the update, because I will update it at the same time for expiration update, and hope it’s available on next week. I am still thinking to make any internal variable become external variable, so it more customizable. And if it’s possible I will put the Ma length variable and CK_Speed variable as external variable so we can make optimization.

After Fixing the bug

Tuesday

2009-04-14T20:26:00.002+08:00

I have a special attention about trading on Tuesday. In my opinion at the normal condition the weekly market open tend to be flat in all markets session. And therefore Tuesday opening tends to be trending. But again this is just my personal judgment; however using indicator may give us a better judgment.
In my post before, I use a combination of Keltner Channels and 2 Deviation Bollinger Bands to confirm trend condition. What a condition that may only easy by eyes looking. But using indicator is a trader choice. Every trader may use a different indicator. And even a same indicator can be used in different way by different trader. It’s trader’s gun in war.
A famous indicator that may be able to help us to detect trending market is Average Directional Movement Index (ADX). Many technicians suggest using 20 levels as a barrier to confirm a trend condition. This is a common use ADX indicator for trend following system. But the most useful information that we can get from ADX value if it’s value broke above 50 levels and then turning down. The common interpretation of this condition is market in correction phase. And as a counter trend strategy, this condition is a sign for our system. Market will be in tight consolidation, and give us trading opportunity.
Tight Consolidation After Long Rally

Scalping Major Pair

2009-04-14T00:22:00.004+08:00

Really it takes more challenge to make scalping system at major pair rather then cross pair. Although they offer a lower spread then a cross pair, but they don’t have any dependency with the other pair.
Although when I create Volatily Scalp System actually to work with EURUSD pair, but until now I never finishing one EA that give a satisfaction result on this pair. The main problem that volatility changes in this pair since July 2008 broke my system.
Applying volatility level could little help to solve this problem. But no one knows when the volatility will be changed. And just like spread filter, somehow this filter can make EA will not work for a long time and may be not work at all.
At the moment I make new research at 5 Minutes Time Frame. Working with little time frame offering a big opportunity since the signals may come often. But the main reason to work a little frame to accommodate an increasing volatility. If you have download my VS_EUROCROSS EA, than you can test it at 5 Minutes Time Frame in EURCHF. You will find a better result especially if you test it since July 2008 when the volatility increase from this month.
An interesting result from my research in EURUSD, that my EA can produce almost a thousand pips from November 2008 to February 2009. And it’s a similar result if we compare to any system that work at same time trading except they trade the cross pair. However the EA keep suffering a deep drawdown. What make it difference that in high volatility the loss may come often than usual, but also the profit can be higher, many trades can be executed, and then may cover our loss faster.

This test just start only July 2008 using 0.1 lots each trade and therefore the result can also measured in pips. The lowest dropping in equity occurred at October, 24 2008 recorded at 9,538 and star to climb after that. It produces about 300 pips a month until February and record 10,835 at that month. Unfortunately it loss about 400 pips in March, but soon recover until end of test.

Scalping EURGBP Pair

2009-04-12T19:12:00.004+08:00

My Current Work on EURGBP using 5 spread
May be this pair is trader’s favors to scalp, especially after Automatic Trading Championship 2008 is over; where there are two EA take the second and third place trade this pair. An amazing result of both two EA can turn up 1000% their account at the end of championship.
After that all broker that use MT4 platform raise their spread for EURGBP pair. And since then almost All EA that trade this pair becomes a looser. In my opinion, while it’s still in high volatility, then we still can make money from this pair. If you have any EA that work on this pair at Asian Session, then do a back test from October 2008- till December 2008. You will find the positive result even at 5 spread. But of course you will get a worst result if you test it below 2008 year, where the EURGBP volatility is low. It can raise a question who likes to scalp in low volatility.
Spread Difference
This is may a funny idea that could help such EA to work under 5 spread. Rather to protect EA not to trade at 5 spread or more that possible not work anymore, we can give a delay for spread difference after our signal was triggered. For example if our EA has a 5 pips target, each time our signal is triggered, than we must wait the price move as much spread difference before executing an order. However this technique only easy on back test environment. But by doing this delay technique in back test, we can measure our signal performance. You will find a lot of winning trades that executed under normal spread, will miss in this new rule. And know running back test again. Now see how much winning trade are left.

int start(){
Double oldspread=3;
Double currentspread=5;
Double diffspread=currentspread-oldspread;
//sell on rsi overbought
If(rsilast < 70 && rsicurrent >=70 && !Waitingforsell) {
Waitingforsell=true;//global variabel
normalprice=bid; //global variabel
}
//cancel waiting if rsi get out from overbought threshold.
If(rsilast > 70 && rsicurrent <70 && Waitingforsell) {
Waitingforsell=false;
normalprice=0;
}
//Time to execute the trade
If(waitingforsell){
If(rsicurrent >=70 && bid >= normalprice+diffspread*point){
Tiket=OrderSend....
If(Tiket>0){
Waitingforsell=false;
Normalprice=0;
}
}
}

}

Running On VPS Server

2009-04-10T14:28:00.005+08:00

I would like to thank to someone who tell me about problem running my EA on VPS that run Windows 2003 Server. I have found some problem in one forum, but at the end of thread no confirmation how the thread starter fixing this problem.
But seems the main problem that what another library that present at Windows XP is missing at Windows 2003 Server. So I have two solutions, to copy that missing file or rebuild the library with static link of Microsoft Foundation Class.
I take the second option, thanks to Marcus who confirmed that it's now work on Windows 2003 Server. This picture show us how to do that.
Select static use of MFC in dropdown list
The disadvantage of using this option that increase file size, and may consuming more our system resource.

Trade Just After Trending

What an important one that may help filtering our bad trade that determining a trend condition on American Season. A high volatility in American season offers a tight consolidation in Asian session. It could be abroad generalization, but what we must take care about sideway trading that the longer market in sideway condition the higher it’s probability to wake up. And it’s better to apply another strategy in this condition.

There are a lot of good indicator can we use determining trending market and easy to use in programming and catching by our eyes. However we can also compare Bollinger bands with Keltner Channels but its only easy catch by our eyes. What I think a good condition that we must look is to find “a wide band” out side the channels. You can see such a sample on the graph below.
Wide Band outside channel

The advantage if we meet this condition, it is offering a higher profit in pips hence the market still in high volatility.

a.m. : ante meridian, meaning before midday, or before the middle of the daylight hours. Also, before noon is used to reduce confusion. For clarity, a person should say 12 Midnight for 12:00 a.m. Ante Meridian is usually referenced in coding comments as:
// a.m. is 00:00:00 to 11:59:59 (hours: minutes: seconds)

p.m. : post meridian, meaning after midday. The time considered to be after noon. For clarity one should say 12 Noon for 12:00 p.m. Post Meridian is usually referenced in coding comments as:
// p.m. is 12:00:00 to 23:59:59.
Time Zones: One of the 24 established divisions or sectors into which the earth is divided for convenience in reckoning time: each sector represents 15 degrees of longitude, or a time interval of one hour. The zones start on the zero longitude in Greenwich, England. Each time zone keeps time slightly differently so that at 12:00 noon the sun will be high in the sky.

GMT: Greenwich Mean Time . GMT is sometimes called Greenwich Meridian Time because it is measured from the Greenwich Meridian Line (Longitude 0) at the Royal Observatory in Greenwich, England. It is the place from where all time zones are measured, starting in 1884. It is also known as the “Universal Time”.

Universal Time: Universal Time is equivalent to GMT. By international agreement, the term UTC is recommended for all general timekeeping applications, and use of the term GMT is discouraged.
It is often referred to as either Universal Time (UT) or Universal Time, Coordinated (UTC). This time is considered to be the most accurate.
It is almost always referenced by a 24 hour clock: 0000 to 2359. Sometimes a Z is appended to the time to indicate a Zero Hour offset because we are referencing the time at the zero longitudinal meridian, as in 1030Z. Pronounced “One Zero Three Zero Zulu.”
UTC is considered to be more accurate for weather, and astronomical applications. UTC can also be obtained readily from the Global Positioning System (GPS) satellites for navigation purposes.

Daylight Saving Time (DST):
About 70 Countries use some form of Daylight Saving time. Because the earth is tilted 23 degrees, we have changing seasons, and shifting sunrise and sunset times [as the earth rotates around the Sun].
The intent is to move 1 hour of daylight from the morning to the evening to make better use of planet Earth’s available daylight. In reality there is no “saving” of daylight. This term could better be depicted as “Daylight SHIFTING time”.

EST: Eastern Standard Time (New York, United States). Add (-5) hours from Greenwich Mean Time. This implies NO Daylight Saving time offset. Although if Daylight Saving time is in effect, most people still refer to the time in New York, USA as EST.

EDT: Eastern Daylight Time. If Daylight Saving time is in effect, add (- 4) hours to Greenwich Mean Time.

Check Your Trading Time
Because each broker may use a different time zone, it’s important to know which time zone they use. Since my Expert Advisor don’t know what time zone the server using, then you need to match its trading time carefully. Usually a broker will tell you what time zone he use in his server, and also a good broker will send to your mailbox a confirmation about time shift that affected by DST. If you don’t have any idea about your Local Time Zone or Your Broker Time Zone, then I suggest you to set your Systems Time Zone to GMT. Just double click the clock on tray icon or enter to your control panel system and click/double click Date and Time icon to show Date and Time properties tab. Switch to Time Zone tab, and the select GMT Greenwich Mean Time on pull down menu.

To remove ambiguity about DST unchecked the checkbox “Automatically adjust for daylight saving changes”.

Now switch to Internet Time tab, make sure your system has internet connection, select time.nist.gov as Server, then click Update now to get current GMT time.

Terms:

Now you can compare your current time after updating with your broker time.

The Entry Rule

2009-04-01T15:56:00.003+08:00

Main rule
Trade only when 20 periods ck_speed indicator is not in green color. And we use Asian market session as time to trade.

Entry rule
Basically each time price penetrates the Keltner channels, than we put our trade there. This approach is the reverse side of VS_EURCHF entry rules. If VS_EURCHF tend to trade inside the channels, then this VS_EUROCROSS tend to trade outside the channel.

If you want to see how VS_EUROCROSS to work, then you need to attach 3 Keltner Channels indicators, and set their fib level to 2.0, 3.0 and 4.0, and attach 1 20 Period ck_speed indicator.

Please keep remembering that we must still use a double spread rules as minimum barrier. This is the step to create signal filter. We take current pairs spread and then we multiply with 2. And now we take the current 20 period ATR value, divided this ATR value with pairs point to get a rounded number. Take the maximum value, double spread value or ATR value; this value will become our signal filter. This technique will guarantee that our minimum profit target as much as current spread. And there are no trades executed if the distance between current price and Moving Average below our signal filter. And finally our trade position will look like this:

- 1st trade must occurs above 1st deviation keltner channels
- 2nd trade must occurs above 2nd deviation
- 3rd trade must occurs above 3rd deviation
- 4th trade must occurs above 4th deviation

Mathematical situation
There is a time that when first trade has executed, than the price not retrace as we expected, rather the price with a slow move go against our position and even without break next deviation upper/lower Keltner Channels.
If our last open price now being equal with the current 20 period moving average, clearly we are in bad trade because whenever the price across the moving average, we still suffering a loss. Therefore meet this situation EA will avoid the rule above, rather as long as price penetrate above/below 1st deviation Keltner Channel, then EA will execute new trade if current moving average value now being equal with our last open position. To simplify we can use bar count method, normally if price back to Moving Average below 6 bars since our entry than we are still making profit there.

It's ready....

Finally, you can download my VS_EUROCROSS version. It will be expired July, 5 2009, and next update will be available after April, 26 2009.
Here the explanations of external variables that EA use:
extern int Magic = 1514;
Magic number if you run several EA at the same time on one account, make sure each EA has a different magic number.

extern int OpenHour = 22;
extern int CloseHour = 5;
These the time trading variable. You should know that at the last 30 minutes of closing hour, if there are no any open positions, then the EA will stop working.

extern bool AllowBuy =true;
extern bool AllowSell =true;
Sometime if you have your own analyzes about market movement, then you can tell the EA to trade only to your direction. Therefore if you only want to go long, then set the AllowSell variable to false, and leave it AllowBuy to true.

extern bool MM = true;
extern bool Marti_MM = false;
extern int Risk = 50;
extern double Lots = 0.1;
extern int LotsDigit = 2;
extern int Slippage = 3;
extern int StopLoss = 60;
Please read my last post before about Money Management, and the new option to use Martiangle money management.

extern double NormalSpread =3;
It’s a special variable to anticipate if brokers raise their spread. The different between current spread with the NormalSpread variable will be added to our signal filter. Therefore if you want EA always to work like a normal spread, set this value equal to current spread. If not, then EA will have a higher signal filter than it’s normally, and therefore will force the EA to get higher/lower price than it’s normally.

extern double MaxDayAtr =250;
This is the filter that we need to protect EA working only below MaxDayAtr.

extern double EquityTarget=0;
extern bool SecureMyEquityTarget=false;
Tell the EA to stop working after current equity reaches our target.

extern int MaxTradePerPosition = 4;
At the moment you can not change this value more then 4, but you change to less than 4.Please read this post about the impact of changing this value.

Only 90%

2009-03-30T20:49:00.004+08:00

Finally a hard week has been passed to build this version using DLL extension. I have to sorry that current work does not have a same result with MQL4 extension. It’s only about 90% of trades that executed using MQL4 only, occurred by using DLL extension. I have tried several times to make it equal. But the last this is my best result. The truth I am not satisfied with this result. The result should be equal because there is no a different in the back test environment. And also I can get the same result if only calculate the Indicators in DLL only rather than to put all entry and exit logic in DLL.
Looking forward I still try to make it equal. But as I promised before that this version will be available this month, and the show must go on. However from now on each time I share my EA, than it will have an expiration time. I hope you can understand this situation. Although I believe that this method can not protect 100% of my work from any scammers, but it can minimized that problem. Someone must be a credible programmer that understands assembly programming to crack a DLL extension. I will update the expiration time periodically a week before current release expiring.
I offer another solution to avoid this problem by allowing anybody who submits its account number. Using account number protection we can throw out the time protection.
At the moment I have no problem to start to share this EA. I have tested this EA several time to catch any bug if appear. And seem it works well. My problem is the documentation doesn’t ready yet. But I decide to put any explanations about this EA only to this blog, rather to make it in a single documentation. This way may will rise this blog hits:).
Compare to my last back test result, it's only 90%

Using DLL in New EA

2009-03-24T12:09:00.002+08:00

It's a hard task for me to program all EA's logic using C++ language. I have to do this to protect my work from scammers. Looking the backtest result may attrack people to sell it.
I also make this experience as a learning process to C++ programming language. Basically I just familiar with Java programming language wich is similar to C++, but in fact it's only easy to migrate from C++ to Java but not in reverse way.
At the moment I try to put all EA's logic in DLL, and it include the indicator calculation. And again for protecting this EA to be sold then it may have an expiration about 2-3 months, if it has not expiration time then it may limited by account number.
More on this new EA, I put new option to use Martiangle Money Management. The advantage of using Martiangle money management that it can reduce our drawdown. For example if we put our risk 50% with number of trade per position are 4, then in normal money management formula it's equal to 12,5% risk per trade. On the other way, using Martiangle Money Management the risk per trade will gradually increase. Using 50% risk with 4 trades per position, I use 10%,20%,30% and 40% formula. Therefore the first trade only use 10% of 50% risk wich is equal to 5%, the second is 20% of 50% wich is equal to 10%, the third 30% of 50% which is equal to 15% and the last trade will risk 40% of 50% which is equal to 20%.
The disadvantages of using this Martiangle Money Management formula, that almost about 40 percent of profitable trades made by a single trade. And it's more then 60 profitable trade made by only 2 trades. However loosing 1 trade using standar money management will make our equity suffer 12.5% drawdown (assuming 100 stoploss and pip's value is rounded to 1 or 10) while loosing 1 trade using Martiangle Money Management only make the equity suffer 5% drawdown.
Another indicator add to this EA to filter out bad trades, and throw out the former filter TradeLowRangeDay and TradeOutSideBand since this new EA only work for EURCHF and EURGBP.
This picture is the latest backtest result, and no more change I'll make, and now I just try to write all EA's logic from MQL4 languange to C++ programming language before sharing this EA.
VS_EUROCROSS_D01 EUROCHF

New EA

2009-03-17T19:40:00.003+08:00

Basically this EA has no much different with the VS_EURCHFD01. Both use same indicators, and also apply spread filter. But the way to make cost averaging make the difference.
The drawdown is 31%, using 50% risk without limitation in lot size as long as the platform allow to trade that size in backtest mode.
I have posted before, that this EA only make a good result in 2008. But by applying a good exit strategi the result on both EA at 2007 has no much different.
Now I still make any documentation about this EA. I try my best to make this EA can be download this month.
Volatily Cost Averaging System

Soon...

2009-03-17T18:15:00.003+08:00

Now the improvement of current EA on EURCHF also break 1 Million result. But seems current month is a hard session for the EA. I am not surprised about this situation if I compare the same period on last 2 year. A deep drawdown always happened at March.
The result of backtest show 38% drawdown that happen this month. Using 50% risk and no limitation in Lots size. This condition will show us the real drawdown, because when I give a limitation in lot size such as 100, then the drawdown in percentage may less.
Some big loss come after EA just made 4 win trades. This could be a potential filter. To stop trade after making several win trades. But let that filter becomes discreation one.

One More Zero

2009-03-15T17:02:00.005+08:00

I have tried several approach to improve the EA. Currently I divide my work in 2 version. First version is an improvement of VS_EURCHFD01 version, you have seen the result on my last post. Really it's 3 times better then current version.
Second version is volatily cost averaging system. This second version break a million result in backtest. Unfortunately the great result only come after 2008. While the result on 2007 first version is better.
That's why I keep to hold my work. I try to combine theese EA and divide the risk.If this combination make a better result in profit and draw down then I would release only 1 version. Otherwise next time I just release them together.

External Variable

2009-03-11T23:03:00.004+08:00

I am so sorry to forget to explain about money management rule.
extern bool MM = true;
Set this value to FALSE if You don't want to use money management.
extern int Risk = 50;
The value in percentage of current margin.
The important point here that Your Risk will be divided by variabel MaxTradePerPosition. For example if MaxTradePerPosition are 4, then it's mean each trade will risk about 12.5 percent. Therefore reducing MaxTradePerPosition will not reduce your risk. But increasing MaxTradePerPosition will reduce Your Risk.
extern double Lots = 0.1;
This is the lot size if You don't use money management.
extern int Slippage = 3;
Remember that You have to match your brokers quotation. If they use fractional pip, You should use 30, not 3.
extern int StopLoss = 60;
This is the stop loss that we use in pip. But this value not depend on your broker quotation.

Make Improvement

2009-03-10T22:10:00.004+08:00

EURUSD
EURCHF
For several days I try several methods to make this EA work better, not only increasing the profit but also try to reduce drawdown. I am not interesting to optimize the parameter value. What I want to try is to reduce our stop loss when trading time has been passed. Seem this method help to reduce the drawdown. There is a trailing function applied here. And also the use of cost averaging system will be confirmed with current volatility. The EA will measure the current volatility to decide how much same position will be opened.
Beside, I try to make it more aggressive in reentry during high volatility, but keep to use old entry rule. I have no attention yet to add another entry rule, except that new entry rule also a robust system.
The results of back test now improve in EURCHF and EURUSD Pair. But this is not the end yet. There are several methods that I didn’t try yet. I hope I can complete it next week

Diversification

2009-03-09T16:34:00.003+08:00

Each time people ask about what pair the best to trade, then my answer always the same, EURCHF. While every time I see my back test result on all pair, I always feel that my system will be better if we diversify our risk. An impressive result of back test in EURCHF, may look interesting to trade only this pair. This is true only if we have enough patients to trade this system. However the back test result show average 1 Month needed to recovery after suffer a loss and 3 Months for the longest time needed to make new peak in our equity.
My fantastic result on first week give me that confidence. When I run my EA on 5 pairs together, mostly the EA will execute trades on mayor pair together. Take long or EURUSD, GBPUSD, while short at USDCAD. Seem all this trade is a single position, shorting USD. And therefore the result will not be different if we put all the risk to 1 pair only. Only for the long term position that conclusion can be true. But since a shorter time frame than the result may be different. The way trend to develop on small time frame will be varying on each pair.
I put 3 pictures taken from my trade to show the sample. Much same situation occurred, and also gives a different result. For this sample trade I suffered a loss from long position in EURUSD, while get profit from long position on GBPUSD and short position on USDCAD.
At this situation, if I close all EURUSD position when USDCAD and GBPUSD have made profit, then overall trade still in positive territory. The fact I keep ride my loss on EURUSD and finally 1 trade stopped out before price crossing MA.
GBPUSD

Trading Jurnal March 3, 2009 Use Filter, dont try in real account

2009-03-03T16:29:00.003+08:00

I make an experiment to avoid the filter in Mayor pair. What I see from yesterday, if avoid the filter, than I can make 2 profitable trade. Well same situation happen today. And also know Daily chart EurUsd show closing below bollinger band. While 5 period day ATR GPUSD shows above 250, it means there are no trades on mayor pair.
To many mistakes today. After loosing in EurUsd, I do not close EURCHF when price across ma. Finally after loosing on UsdCad, I decide to close any position, and let my equity back to where it begin. Yeah loosing all profit since a week.

Trading Jurnal March 2, 2009 A Wrong Decision

2009-03-02T16:51:00.004+08:00

I made a big mistake to let EA runs on GBPCHF. I did it cause I know USDCAD will not make any trade today since Daily chart penetrate Bollinger Bands. It's a hard decision, to configure USDCAD so it may trade, or to trade GBPCHF. I decide to trade GBPCHF, and then get 2 loss!!.
Am I get loss today? No. I still make money amount 200$. A superior performance come from GBPUSD pair. 3 positive trade can recover 1 loss. Another profit as usual come from EURUSD,EURCHF, and EURGBP. I could make 1000$ today, if that happen a 100% profit become easier this week. But 2% profit not bad, and it means know my equity grow 40% from capital. It's not impossible to get 100% grow this week.
Here my statement today.

And the complete statement till know.

Don't leave it, except if you only run it on 1 pair. Read my trading journal, sometime i need to stop the EA on 1 pair, then to trade it manual. It will be clear if you have read the system, learn for a while the system. It's an easy system.

Trading Jurnal 27 02 2009, 35% Profit a Week

2009-02-27T18:29:00.004+08:00

A lot of surprise today. I start my trade at 0 GMT, and soon get trade from all pair. First surprise for the first time EURGBP make a profit faster then the others. But it make me unconfortable, all others pair make their first cost averaging except USDCAD, and than I get second surprised. Much a quick trade today. GBPUSD, EURUSD, and USDCAD close their trade below 30 minutes. Only 1 hour trade i have make profit about 250$, but still EURCHF doesnt hit its target, thats way make unconfortable, since this pair my favour. Do I have to stop my trade if this last trade hit it's target, or just close all position right know while my loss only 30$?
I decide to continue to trade, and then EURGBP make a trade again as same as USDCAD. Finally, just a minute before 5 GMT, I decide to stop all EA that not have any trade, and wait for USDCAD and EURCHF and EURGBP to complete their trade. And soon all trade hit their target give 510$ profit today, and complete a 35% profit for a week. The last surprise almost quarter of todays profit come from 3 trades on USDCAD.
This is my statement today, it's not include the first trade from EURGBP since on history they recorded as yesterdays trade.

The statement for a week:
