By pipstep, I mean range. If the second positions buy 20 pips above the first, then the pipstep is 20.

I think we need the EA to change the TP, SL, and pipstep depending on the pairs range. If the pair ranges 20 pips, and the pipstep is 20, it could just keep buying high and selling low. So, some indicator would be used to reduce the pipstep to say 5, so you would get 3 winning positions in a row before a reversal.
