Convert simple Lot Size input into a calculation (Based on Stop Loss and account Balance)

[Mher Karadjian]

Hey! I'm new to MQL.

I have this simple MA Crossover EA (attached in txt) I'm using and I want to have the Lot Size calculated based of % risk (Given Stop Loss in Pips and account balance).

I'm trying to implement the code from https://www.earnforex.com/guides/how-to-calculate-position-size-in-mql4/ but I keep getting undeclared variables and global and local variables mixing.

I'm sure its as simple as naming the variables properly but I cant seem to figure it out. I have experience in coding python but it's not helping with MQL.

Would anyone be able to implement this and show me how it works?
