How much does the tick path change your EA test? - page 2

On short-target systems I see the same split you do. Once both sides of the bracket can fit inside one M1 bar, I'd treat the real-tick run as the only one that counts.

One gold comparison, since I test both platforms: MT5 "Every tick based on real ticks" is not the same as MT4's "Every tick." MT4 builds ticks from M1 bars, so it can look closer to "1 minute OHLC" than people expect. If someone only shows an MT4 every-tick report, I want the same window in MT5 with History Quality close to 100% and the same lot.

Don't judge the two modes by net profit alone. A few extra winners can move the dollar total a lot while profit factor and relative drawdown move less. On XAUUSD, put commission and swap in both models; a real-tick run that still omits swap isn't a fair live proxy.

Your deal-list diff is the right habit. The first trade where entry matches and the exit doesn't is usually the assumed M1 path or the spread at the exit.
