2 Hours Delay on Weekly Opening

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.
