Margin Calculation Documentation Question
In the MQL5 help file we see the following table documenting how margin is calculated for each type of instrument:
ENUM_SYMBOL_CALC_MODE
| Identifier | Description | Formula |
| SYMBOL_CALC_MODE_FOREX | Forex mode - calculation of profit and margin for Forex | Margin: Lots*Contract_Size/Leverage Profit: (close_price-open_price)*Contract_Size*Lots |
| SYMBOL_CALC_MODE_CFD | CFD mode - calculation of margin and profit for CFD | Margin: Lots *ContractSize*MarketPrice*Percentage/100 Profit: (close_price-open_price)*Contract_Size*Lots |
| SYMBOL_CALC_MODE_FUTURES | Futures mode - calculation of margin and profit for futures | Margin: Lots *InitialMargin*Percentage/100 Profit: (close_price-open_price)*TickPrice/TickSize*Lots |
| SYMBOL_CALC_MODE_CFDINDEX | CFD index mode - calculation of margin and profit for CFD by indexes | Margin: (Lots*ContractSize*MarketPrice)*TickPrice/TickSize Profit: (close_price-open_price)*Contract_Size*Lots |
| SYMBOL_CALC_MODE_CFDLEVERAGE | CFD Leverage mode - calculation of margin and profit for CFD at leverage trading | Margin: (Lots*ContractSize*MarketPrice*Percentage)/Leverage Profit: (close_price-open_price)*Contract_Size*Lots |
I have searched high and low, and cannot find a way to determine what the instrument's Percentage is. What call is made, with what enum to get this value?
Thanks!
