I think I know now what the problem is. It dont work, because S/L and T/P set at the same time.
Can someone modify it, that the EA open first a order, then set the S/L and T/P ?
Thanks for help.

You know what/how I must modify it? My MQL is bad.

Thank you,
my broker told me now, it is not allowed T/P and S/L with the ending like .02 only with ending .0 or .5
Because the price change is 0.5 points. If S/L is .03 its not working.
Can you help me please what I must do?
I trade the germanDAX and the backtest is great.
