Problems with multicurrency testing on MT5

New comment



I'm trying to do the first tests with my new multicurrency EA, but the tester makes an error and the test doesn't start. The mistake is this. Basically, I'm trying with only two currencies and there is a problem loading the second currency indicator. Where did I go wrong?

I add that the problem is only created on the tester, while on the MT5 in real time it works well, with no errors.

Sorry, I was pointing the second currency NSDUSD instead of NZDUSD. After a whole day of programming I think I'm tired.
