https://www.myfxbook.com/strategies/revtraderpro-eurusd-cp/76349The variation in results are mostly from how the RTP uses the Grid feature. Their grid function is not consistent with the values you insert within the EA parameters.

REP uses only 1 grid setting and it checks the OrderOpenPrice to compare when it is ok to insert another trade. Results from REP are better based on this short 1 year backtest using control points on EURUSD. I haven't optimized any setting and only used the setfile from RTP.
