EA works great in strategy tester, but not in live trading

So the EA opens up a trade based on risk I set on EA options. Say I set the acc size to 1000 and risk to 1. That means the EA will risk 100$. SL should be at -100$. and TP is 1:1 so at +100$- lot size will be calculated automatically. It works 100% perfectly in Strategy tester. But on live the SL would be at like -2$ and completely wrong Lot size and TP is far away but still +100$. So anyone knows why is this happening. I have searched for 2 days in all kind of forms, but no one seems to have experienced this error.

I have checked ECN broker and how the affect the ordersend function.
Tried with 5 different brokers.
Asked in MQL5, but no answer yet.

So what is the difference between Strategy tester and live that causes this massive discrepancy? - Strategy tester is 99.90 modeling quality, but this is not important since the logic of the EA is different in live for some crazy reason.

Spread will not have that big of an effect on my strategy as I am not scalping and trading on specific times only where the spread is very small. The thing is even if we account for the spread, EA on live puts the TP 50 pips away from where it should be, whilst in strategy tester it's placed perfectly where it should be. Same as lot size, should be like 0.3, EA makes it 0.05 in live.

Did you code the EA or you bought off somewhere else? If you bought it, I suggest you contact the seller and ask them why. The thing with EA is most of them were bring out a perfect results on historical performance whereas on future no one knows. There're a lot of Logic behind the EAs code. Try to run it for a month on Demo, put the Demo balance the same as amount you willing to deposit the account. So you'll see what configs the EA will actually use.

I hired a coder to make the EA, we were debugging it together. I have a weak background of coding, can't write from scratch, but can fix and modify the codes. Thing is he will be away for sometime.

All i can think of is if you are using ATR as a stop. Yen pairs have a different digit decimal and requires additional adjusting. Otherwise, i'm not sure what else it could be. Good luck.
