[132]Emergency issues for the purpose to close position with FIFO

I want to build a template for build the strategy with FIFO in MT5 netting mode.
First, I find I can't use the action "Close position" to close the fixed lot I want. (photo1) I only can close full position just like Close all position.
So, I don't understand what is the different between them.


Second, because of the reason above I change my thinking try to reach my purpose.
So, I change all exit action to open the opposite position when my conditions was true.(strategies in attachments)
It can build well in SQX.
But I find 3 obviously issues.
1. It can't get "drawdown" and "open drawdown" very well.(photo2)
2. It can't calculate the MAE/MFE well.(photo3)
3. In "MonteCarlo retest" with this trading construction it can't get any result.(always 0 and no result) (photo4)
4. It always show "too many trades close at the same bar" error.(strategies in attachments)
Can you help me to check those issue above, thank you.
