@seb-0 the "TP or SL trigger choice problem" might not be the reason here, as there is supposedly always min 20 pips difference between those levels.
I am very interested in this, but purely from the point of figuring out where the tester goes wrong, in what detail does the devil hide...
@Julianrob your mt5 backtest shows much larger "largest loss trade" while the mt4 backtest seems to have a fixed SL, largest being the same as average. -55 vs -6. So there is some different trading logic going on.
