Hi Pandion,
That’s always a big question when testing an EA, which is why we can’t assist trouble-shoot specific EAs. The best advice we can give is to firstly test with the standard ‘MACD Sample’ EA and ensure you are getting modelling 99.9% quality. After that, it is likely that your EA is sensitive to one of the parameters such as spread, causing it not to trade. Other problems may include parameters such as lot-size, tick value (etc) being incorrect in the exported data. In this cause, you should be able to nail down the exact parameter that is causing the issue by logging the error code you get when trying to place an order. If you don’t have the EA’s source code, you will need to consult the vendor to see if they can assist.
Hope this helps.
