I really spent a lot of time trying to find the trades that don't match to no avail. I spot-checked about 30 trades and they were bang on to the point, I also analyzed the equity curve to try and figure out where the missing performance has gone. It's missing 3 trades with the newest mqh file but 1.27 profit factor turns into 1.21 in mt5 terminal which is not a small difference. Every tick real tick real spread. Charging just a little more commission plus the exact correct amount for swap in SQX so performance in MT5 retester should be at least slightly better. Other strategies haven't had this problem.
