OrderCalcMargin() gives error - 4014: System function is not allowed to call

[George Goudinakis]

Could anyone shed some light on this error, I am adding an example code

#property indicator_chart_window
int OnInit()
{
    double dVol = 1.0;
    double dMargin = 0.0;
    double dAsk = SymbolInfoDouble(_Symbol, SYMBOL_ASK);

   if(!OrderCalcMargin(ORDER_TYPE_BUY,_Symbol,dVol,dAsk,dMargin)) {
        Print("Last error = ",GetLastError());//,": (OrderCalcMargin()) ",ErrorDescription(GetLastError()));
   }

   Print("dMargin = ",dMargin);

   return(INIT_SUCCEEDED);

}

Many thanks

George
