Backtesting net profit

Dear team,

I noticed big differences in the Position.NetProfit during backtesting between the History Tab and what is resulting in coding.

I'm attaching a simple BOT that opens some positions with 10 pips take profit and 10 pips stop loss.

The sample BOT is either writing to console the NetProfit when the position is closed and OnStop.

My questions are:

• Am I doing something wrong? Do you have a workaround? Fix?
• Is this problem only happening during backtesting and not in real trading on either demo account and live account?
• Is there a reason Why the Position ID is mismatched? (for example in the History the position ID=1 is EURJPY and in the code is EURAUD)

Thanks a lot for your help, ciao!
