Re: Advice needed - Portfolio Expert vs MT5 completely opposite backtest
Hello, After testing the same Expert Advisor on several MT5 platforms, I found that the quality of the backtest history was very low unlike the MT4 platform, this may be due to brokers because they can make changes in the data of the history they import into their demo account.
I tested the same EA over the same timeframes with the same settings on 3 different brokers and got vastly different results.
