使用 MQL4 限制每对交易

Question

I want to limit the number or trades/orders in MT4 using my EA in MQL4. I want the limit on each pair not on all Pairs, like: If the condition / logic match then 2 trades will be executed on Each currency where the EA is attached.

This is the code i tried, but it limits the trades on all pairs where EA has been attached.

    }

   else if(SAR<Open[0])
    {
     Ticket=OrderSend(Symbol(),OP_BUY,lot,Ask,10,Bid-SL*Point,Bid+TP*Point,"Done By MSZ.Inc");
         if(Ticket<0)

         }
         else
         {

     }
    }
    }
    else
    {
    Alert("Orders Limits reached");
    }
  }

I want that it will execute 5 orders on Each Chart where the EA is attached.

Answer 1

**if(OrdersTotal()<=MAX_ORDERS)**

This may send up to 6 trades due to the = sign. It will also top up trades either buy or sell at any time until the <= condition is met. To clarify, are you meaning to hedge? Your MAX_ORDERS is defined as a pre-processor directive. input int MAX_ORDERS =5; to be able to change this value.

Answer 2

#define MAX_ORDERS 5 在 ea 脚本开头输入 this 后是否需要在脚本后面添加 **if(OrdersTotal()<=MAX_ORDERS
