I need as this

Help me write a method to implement a partially closing strategy combined with Martingale/Grid.

My conditions:

I have hedged both buy and sell positions at 1.5 lots.
I opened a new position using Martingale starting with 0.2 lots.
What I need:
If the Martingale position generates profit, I want to gradually reduce the hedged position (1.5 lots) by closing portions of it step by step, e.g., from 0.2 lots to 0.1 lots, and so on.

However, I couldn’t implement this logic successfully. Please help me!
!
