Hello. Okay, It is very easy for me.
I have enough experience in MQL4 and MQL5.
I can solve your problem in short time.
To modify your Expert Advisor (EA) to maintain a given stop loss value after slippage, you would need to add a function that checks the slippage and adjusts the stop loss accordingly. This function should be called every time a trade is executed.
I will wait your response.
Thanks
