[HELP-resolved] SymbolInfoDouble Margin Initial returns zero?

[Nuno Madeira Amaro Pire Costa]

Hi all.

I am trying to workout how can I get this "3" that I see on the symbol specs on my broker.

But SymbolInfoDouble Symbol Magrin Initial returns 0.0

SymbolInfoDouble(par,SYMBOL_MARGIN_INITIAL)

So I ran them all and displayed as comment to debug:

   Hints +="\nMargin Hedged : "+SymbolInfoDouble(par,SYMBOL_MARGIN_HEDGED);
   Hints +="\nMargin Limit : "+SymbolInfoDouble(par,SYMBOL_MARGIN_LIMIT);
   Hints +="\nMargin Long : "+SymbolInfoDouble(par,SYMBOL_MARGIN_LONG);
   Hints +="\nMargin Maint : "+SymbolInfoDouble(par,SYMBOL_MARGIN_MAINTENANCE);
   Hints +="\nMargin Short : "+SymbolInfoDouble(par,SYMBOL_MARGIN_SHORT);
   Hints +="\nMargin Stop : "+SymbolInfoDouble(par,SYMBOL_MARGIN_STOP);
   Hints +="\nMargin StopLimit : "+SymbolInfoDouble(par,SYMBOL_MARGIN_STOPLIMIT);
   Comment(Hints);

To my surprise... all came as 0.0

How can I get that 3?

Thank you

Nuno

Don't make it difficult for yourself. Just use OrderCalcMargin ...

OrderCalcMargin

Calculates the margin required for the specified order type, in the deposit currency

I already check that before an OrderSend, inside this funcion:

bool CheckMoneyForTrade(string symb,double lots,ENUM_ORDER_TYPE type)
  {
//--- Getting the opening price
   MqlTick mqltick;
   SymbolInfoTick(symb,mqltick);
   double price=mqltick.ask;
   if(type==ORDER_TYPE_SELL)
      price=mqltick.bid;
//--- values of the required and free margin
   double margin,free_margin=AccountInfoDouble(ACCOUNT_MARGIN_FREE);
   //--- call of the checking function
   if(!OrderCalcMargin(type,symb,lots,price,margin))
     {
      //--- something went wrong, report and return false
      Print("Error in ",__FUNCTION__," code=",GetLastError());
      return(false);
     }
   //--- if there are insufficient funds to perform the operation
   if(margin>free_margin)
     {
      //--- report the error and return false
      Print("Not enough money for ",EnumToString(type)," ",lots," ",symb," Error code=",GetLastError());
      return(false);
     }
//--- checking successful
   return(true);
  }

My intent now is, when the result of this check is negative, I can retry with a new lower volume that fits the margin.

How can I go that?

Maybe if I make that "margin" a global double variable, and retry with

new volume = Free MArgin * Old Volume / margin?

Yes, by simple maths and by also checking the amount of available free margin (and if you need, also used margin from other open positions) ...

AccountInfoDouble
