i got some problems with backtesting and historical data.
I used for my EA a backtesting-periode of "5 min" on "EURUSD" and a timeframe from "2009.01.01 - 2011.02.18" and tested it on 3 metatrader-Accounts (4XP, InterbankFX and IncoNeon) with different results:
- 4XP( Profitfact. - 1.07)
- InterbankFX( Profitfact. - 0.78):
- IncoNeon(Profitfact. - 1.21):
Where do i get good historical data or which data provider did you prefer to get responsible results ???
