Hi,
I'm really new to programing amd I decided to make the first tryout changing the MACD sample EA, but I can't get it to work, I get always the same errors in the tester. Then a installed the MetaTrader again and I don't get the error messages, but it doesn't trade.
Can anyone give an hand? Thank you very much.
