如何将发送订单从 mql4 转换为 mql5

Question

以下是我在三分钟后未通过时下单的方法。我已经将它的大部分从 mql4 转换为 mql5。这只是注释部分，我不确定我将如何更改为 mql5，因为在 mql5 中发送订单返回 bool 而非 int。如果我能得到帮助来修复剩下的部分，我会很高兴。

void MakeOrders()
{
   static datetime lastTime = 0;
   datetime currTime = iTime(Symbol(),PERIOD_M3,0);

   if (currTime>lastTime)

   {
      for (int i=ObjectsTotal(0, 0, -1)-1; i>=0; i--)

      {
         string name = ObjectName(0, i, 0, -1);

         if (ObjectGetString(0, name, OBJPROP_NAME, 0)==OBJ_RECTANGLE && ObjectGetString(0,name,OBJPROP_TEXT)=="")
         {
            double entryPrice=ObjectGetDouble(0,name,OBJPROP_PRICE,1)-3*_Point; 
            double stopLoss=ObjectGetDouble(0,name,OBJPROP_PRICE,2); 
            double slDist=fabs(entryPrice-stopLoss); 
            double dTakeProfit=entryPrice-2*slDist;

            MqlTradeRequest request={0};
            MqlTradeResult  result={0};
            //--- parameters of request
            request.action   =TRADE_ACTION_DEAL;                     // type of trade operation
            request.symbol   =Symbol();                              // symbol
            request.volume   =lotSize;                                   // volume of 0.1 lot
            request.type     =ORDER_TYPE_BUY_LIMIT;                        // order type
            request.price    = entryPrice; // price for opening
            //request.deviation=5;                                     // allowed deviation from the price
            request.magic    =magicnumber;                          // MagicNumber of the order
            request.tp       = dTakeProfit;
            request.sl       = stopLoss;
            //--- send the request
            if(!OrderSend(request,result))
             PrintFormat("OrderSend error %d",GetLastError());

            /*
            int ticketSell = OrderSend(Symbol(),OP_SELLLIMIT,lotSize, entryPrice,0,stopLoss,dTakeProfit,"SellOrder",magicnumber,0,Red);           

            if (ticketSell>0)

            {

               ObjectSetText(name,string(ticketSell));

               i = ObjectsTotal()-1; // rather than continuing the 'for' loop, we must restart because arrows (ie new objects) were created.

            }
               */
         }
      }

      lastTime = currTime;

   }
}

Answer 1

if(result.retcode==10009 || result.order>0)
     ObjectSetText(name,string(result.order));
