I am testing a strategy and I get two much different outputs from 2 different ProBackTest instances, from Sept. 18th 22:00 (utc+2) through Oct. 17th 22:00 (utc+2).
ProBackTest from IG real and demo accounts yield +151.5% over 14 trades.
ProBackTest (10.3 beta) from PRT, both in tick and classic mode, yields -2,55% over 12 trades.
Same spread and same capital to start with.
Do data from PRT and IG differ?
Thank you.
