Require Custom Money Management Feature for an Existing MQL5 EA

:) Hello Sir,

I have an MQL5 expert advisor, which is working perfectly well

Right now, it calculates lot size on the basis of a simple standard formula i.e. Auto Lot Size = Risk Per Trade % / Stop Loss

I want to update it with a custom money management feature which automatically calculates the lot size for the next trade with reference to the current account balance status i.e. if the account balance has increased or decreased from the specified date? then based on that it calculates with the help of a formula as how much stake is required to be risked for the next trade?

The detailed specification of job with example will be discussed via private message

Thanking you
