2 x different pairs on strategy test

No. Mt4 Strategy Tester doe-Not support Multi-Currency back-tests. Depending on the type of Multi-Currency backtest you're trying to perform there may be simple workarounds for you. Search Google. Something like "Mql4.com+Multi Currency Backtest".

ok will try it

thanks

I want to do the same thing. I think you need to download all the involved pairs into an appropiate folder in the minimun time frames posibles.
