Risk % per trade on MQL5

 

Can anyone explain or show me an article where is shown how to use the "#include <Expert\Money\MoneyFixedRisk.mqh>" file?

I have check online and I cannot find a way to use this in order to calculate lot size according to a % of the balance or equity.

I know that on MQL5 we can "generate an expert". I have done this and have found the FixedRisk.mqh file works perfect, but I don't know how to call that in my experts.


Please help!
