I downloaded several expert advisors from codebase. as a result, the expert Advisor in the tester trades on demo no. I passed the same period in the tester as on the demo, there are no errors in the logs on the demo.
The question arose, could it be that the EA was written for netting orders and therefore cannot open trades on hedge accounts? Although the account in the tester, for example, I also had a hedge account.
That is, the adviser for a netting account will open on a hedge account or not and Vice versa?
