return value of OrderSend should be checked

New comment
 

Hi all,

I couldnt find any solution that worked on the following problem:

I added a new "Order function" to my EA, but everytime I get the warning "return value of OrderSend should be checked". The EA doesnt open any trades anymore.

void BuyOrder()
{
    
    //--- prepare a request
    MqlTradeRequest request;
    ZeroMemory(request);
    request.action = TRADE_ACTION_DEAL;          // setting a deal order
    request.magic = 1;                   // ORDER_MAGIC
    request.symbol = Symbol();                   // symbol
    request.volume= Lots;                      // volume in lots
    request.price = Ask();
    request.sl = Low(current+1);                     // Stop Loss specified
    request.tp = 250;                   // Take Profit specified
    request.deviation= Deviation;             // deviation in 5 points
    request.type = ORDER_TYPE_BUY;
    request.comment = "Order";
    
    MqlTradeResult result;
    ZeroMemory(result);
    OrderSend(request,result);
    // check the result
    if (!IsError(result, __FUNCTION__))
    {
        
    }
}

Any ideas where the mistake could be?


Thansk in advance!

Try by changing this line of code:


bool success = OrderSend(request,result);


Whether you use the boolean " success" or not is not so important, the compiler wants to see that you define and assign it.

thanks for your quick reply. I really appreciate it!!!

I still get the same Warning and still no trades.... Do u have maybe another idea?
 

You have to analyze the result to see if the action was successful or not.

I was wrong. As Marco indicated you actually have to analyse the result.
 

please how can I loop over my positions and select a position to further work it?

The code below works for MQL4 but I need MQL5 code that will do exactly the same thing.

Please I need help on this.

int openOrders = PositionsTotal();

for(int i = 0; i < openOrders; i++)                                            

      {                                                                                                                       
                                                             
         if(OrderSelect(i,SELECT_BY_POS) == true)               
         {                                                        
            if(OrderMagicNumber() == magicNB)                       
            {       
               return true;                                            
            }                                                        
         }      

      }                       

Thanks.
