Following high time frame trend and use ATR break to pull the trigger. I use bollinger to make sure the trend is strong. I only place long order when the current price is more than upper band of bollinger and place short order when the price is below the lower band of bollinger. In Aug I think EURUSD should be very strong oscillation. So I choose EURUSD pair, Use 15min Bollinger(20,1,1) to make sure it is very strong short trend. Use 1 min ATR(4) break to place the orders. Set TP small to 4 pip and SL to 80 pip. I don't have Method of trade volume calculation. Just set to 1 lot and after a few profitable days set to 6 lots.
