I am not coder but those EAs are really simple, Well, Just able to modify a old dump EA to test EURUSA for 6 month data, It seems that Paulus setting is right, For Stoploss, It is best near 16-17pip, while profit taking is near 45pip to 50 pip, best entry time is near 30 min to 1 hour after London time, However, It needs human to look at chart for best decision for bigger profit.
However, With very limit data, AUDJPG is better than EURUSA, For 4 weeks data, best setting for stoploss is 18 pip while profits 52pip at AUD market open time, It might be good for your guy to enter order before sleep.
EA is very limit in power, Human can do better for pattern reconnization while EA can do very fast ordering with many small tweak.
