Perhaps you could try and make it close all opposing trades when a strong Opposing/reversal signal comes in, like for example you get a Nice BUY run .... and maybe get a 100 pip stretch, if you got a Strong sell signal from some indicators you could program a SELL trade to open concurrently closing all BUY trades currently running,
or else youll just have to try the 75%/80% stop loss retrace function . basically if trades maximum pips go to 100 .. it will TP at 80 or 75 pips depending on where it gets triggered.
