[131] Emergency AlgoWizard template custom close position size

According to MT5 futures trading rule with FIFO, I want to build strategy with template for close my open position by fixed lots not full position.
I find I can set the variables with fixed lots for use only in Entry order. But I can't use it when I want to exit order.
Can it possible to let me set the same variables with the fixed lots I want.
It can resolve the MT5 future trading with FIFO well.
Because MT5 netting will combine all entry orders into one, It will combine all position into only one order.
If I only can close all position in one order that's mean I can't running multi-strategies with the same account.
So, it's the only one way to create a portfolio trading in MT5 netting account, thank you.
