Help with retry for opening an order

[Ian]

Hello,

I'm just starting to look at MQL5 and now that I've successfully opened an order I would like to convert my MQL4 OpenOrder() function into MQL5.  If someone could give the equivalent MQL5 code for the MQL4 code below it would be greatly appreciated; hopefully someone has already coded something similar.  BTW - is this needed in MQL5?  I had to have retry logic in MQL4 with my broker.

Thanks!

int OpenOrder(int type)
{  
   lastErr = 0;

   for(int c=0;c<Retries;c++)
   {
      RefreshRates();

      if(type==OP_BUY)           {double price=Ask; double sl=Ask-StopLoss*myPoint; double tp=Ask+TakeProfit*myPoint; datetime exp=0; int clr=Green;}
      else if(type==OP_SELL)     {price=Bid; sl=Bid+StopLoss*myPoint; tp=Bid-TakeProfit*myPoint; exp=0; clr=Red;}

      if(StopLoss==0)    sl = 0.0;
      if(TakeProfit==0)  tp = 0.0;

      string orderPrintString = "type = " + type +
              " Lot = " + DoubleToStr(InitLot,2) +

      ticket=OrderSend(Symbol(),type,Lots,price,Slippage,sl,tp,ExpertComment,MagicNumber,exp,clr);
      if(ticket > 0) {break;}
      else   // error opening the order
      {
         int err = GetLastError();
         Print("Error Open Order: # " + err + ": Description = " + ErrorDescription(err) + "\n" + "OrderInfo: " + orderPrintString);

         {
            Print("Invalid Price; sleep and retry");

            Sleep(100);  // wait .10 secs
            continue;
         }
         else  // other errors -- exit, open order failed
         {
            if(err==134) lastErr = err;
            Print("Will not retry");
            break;
         }
      }
   }

Try to insert source code properly.
