here are some values i dont understand about margin calculations in different instruments, (which is shown at https://www.mql5.com/en/docs/constants/environment_state/marketinfoconstants#enum_symbol_calc_mode)
as in SYMBOL_CALC_MODE_CFDLEVERAGE -> Margin = (Lots*ContractSize*MarketPrice*Percentage)/Leverage,
what exactly is the 'Percentage' here. percentage of what? is it a return value of a function? or we set it?
can someone explain please..
