I need to open a position that is larger than the broker's limit

[Jing Wang]

Hi, everyone. I'm wondering if someone can help me on this.

Suppose I need to open a 112 lot buy trade while the broker only allows max 50 lots in a single trade. So I need to break up into 3 trades 50 lot, 50 lot and 12 lots.

the following code does not work and I don't know why. In back test it just keep opening multiple trades even if the total lots exceeds 112 lots.

///////////////////////////////////////////////////////////
void TradeBuy(void) {
 double l=0; double lot_counter=0;
 int i=0;
 order_ticket=-1; order_ticket1=-1; 
   RefreshRates();
   GetMarketInfo();
   int MaxLot=MarketInfo(Symbol(), MODE_MAXLOT);   
   
 
 //---lot calculation
 
 if(condition==True){
   l=112;
   lot_counter=l;
        }
 if(l>MaxLot)l=MaxLot;
 while(lot_counter > l){

                //---Placing the order 
                 while(order_ticket<0 && i<5) {   
                // Sending a trade request  
                order_ticket=OrderSend(Symbol(),OP_BUY,l,Ask,Slip,0,0,orderComment,Magic1,NULL,clrBlue);
                if(order_ticket<0) { 
                if(!Errors(GetLastError())) return; }
                 else {
                OrderPrint();
                }
                i++; } // end of while 
        lot_count = lot_counter - l;
        l = lot_counter;
        if(l>MaxLot)l=MaxLot;

        }// end of while
}
