Margin exchange rate cannot be calculated

Hi,

I was trying my hands out doing backtesting and imported dukascopy data and ran a new MT4 offline for backtesting. However I keep getting this error message. Answers I found seems to suggest I need to get online and then offline once, before this error will disappear. However, every time I get online, the data will be replaced by the server’s data and the dates are too little for backtesting on M5.

Any advice will be greatly appreciated.

You can try clicking on Expert properties in the strategy tester, in the testing tab, make sure that the currency is set to your account currency.
