One of my trading colleague gave this idea.

Draw EMA 144 close (yellow) and EMA 169 close (red) on H1 GBPUSD chart.

Enter 2 lots when H1 candle closed above the "tunnel" for BUY. 1st lot take profit 15pips. 2nd lot trail 20pips or move SL to entry price after +15.

Take every trade for every closing above and below.

I think this is mechanical enough to make an EA.

If there is an EA relating to this strategy, let me know.

Thanks
