Create MQL5 wizard module (monay management)

Hi

I need money management module for MQL5 wizard.

the module determines the lots size based on account balance, risk and SL.

SL -set by user (eg. 300)

balance - from system (eg. 2000)

risk -set by user(eg. 2%)

max_lot - set by user (eg.50)

amount_risk = balance * risk

point = 0,00001

lotsSize = (point*amount_risk)/((SL*point)*10) //I hope my thinking is good

if lotSize >  max_lot then lotSize = max_lot

Thank you, I hope it is well described, it should not cause a problem for the programmer.
