This startegy uses Fib level (0.618) of Bollinger Band for long entry. I find this is the only strategy which gives similar results on the different time frames. I have tested QQQ for 1H, 2H , 3H and 4H charts , all showed over 70% winning rate.
BB settings 50 , mult 1.5 (or you can use 2.5 or 3 )
Note: for the basis I have used VWMA instead of SMA...
