EA with DLL

 

Hello friends,

I have an EA that uses DLL imports to read history data. It gives good results on backtest but fails in live trading. Please what could be the possible explanations?

Using DLL to read History data?

There is only one reason for that, to trick the back-test and scam the potential buyer of the EA!

It must be a MT4 EA obviously!
