Scalping And Volatility

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.
