@tickstory : Thanks for that new feature !
I was able to import 2years DAX data, map it to DE.30.. which is my broker code for the DAX CFD, as well as inputing the correct symbol properties (tick, digit, size, margin…) so the charts are fine and the quality is 99.9% when backtesting
But the problem I get is my eas don’t trade during the backtest on these data (I get messages like “cannot calculate exchange rate” or “tester cannot calculate prices” or others)
2 remarks:
– on my other MT4 instance connected to my broker these ea backtests are fine (but only up to 3 month)
– I don’t have this probleme on EURUSD or other tickstory currencies
I suspect it could be wrong parameters input by me in the MetaTraderInfo tab. I attached it so you may be able to give me a clue : 
Thank You !
