Can any body help me with this

Milan Yonjon 2019.06.28 15:09

After compiling it shows that "not all control path returns value"

where is the mistake?

Can anybody suggest me?

bool DTNAR()
{

double DTNAiPtFc=100;
double buyprice,sellprice,pointDTNA,AskV,BidV,pacal;
buyprice=MarketInfo(Symbol(),MODE_ASK);
sellprice=MarketInfo(Symbol(),MODE_BID);
if(DTNAiPtFc>0)
   {
     
      int y=0;
      int z;
      pointDTNA=MarketInfo(Symbol(),MODE_POINT);
      for (z=y;z<=DTNAiPtFc;z++)
         {
         pacal=pointDTNA*z;
         AskV=buyprice*pacal;
         BidV=sellprice*pacal;
         if(AskV>0&&BidV>0)
            {
               for(int TrC=OrdersTotal()-1;TrC>=0;TrC--)
                  {
                     if(!OrderSelect(TrC,SELECT_BY_POS))continue;
                     if(OrderSymbol()!=Symbol())continue;
                     if(OrderType()!=OP_BUY||OrderType()!=OP_SELL)continue;
                     if(OrderOpenPrice()==AskV||OrderOpenPrice()==BidV)
                     return(true);
                     Print ("Double trade zone");
                     
                  }
            }
         }
   }
   else return(false);
   
}

Mladen Rakic:

Thanks for the reply

But I still have one question

what might be the solution to that so that the condition will return value true or false.

I would be great to see the suggestion.

No idea what are you using that code for

You had an issue, and it is solved. The rest is on you

Actually I want the for loop inside for loop to return a value for the whole bool function.

If, any one can help, thats great,

if not also its okay.

Post the code here with tags, no image, so readers can make amendments.

This cannot work:

if(OrderType()!=OP_BUY||OrderType()!=OP_SELL)continue;

It will never be true. Try this:

if(OrderType()!=OP_BUY && OrderType()!=OP_SELL)continue;

Thanks for your reply to my question.

Actually I am not being able to return the value from the inner for loop to the whole function.

Here is the code:-

bool DTNAR()
{

double DTNAiPtFc=100;
double buyprice,sellprice,pointDTNA,AskV,BidV,pacal;
buyprice=MarketInfo(Symbol(),MODE_ASK);
sellprice=MarketInfo(Symbol(),MODE_BID);
if(DTNAiPtFc>0)
   {
     
      int y=0;
      int z;
      pointDTNA=MarketInfo(Symbol(),MODE_POINT);
      for (z=y;z<=DTNAiPtFc;z++)
         {
         pacal=pointDTNA*z;
         AskV=buyprice*pacal;
         BidV=sellprice*pacal;
         if(AskV>0&&BidV>0)
            {
               for(int TrC=OrdersTotal()-1;TrC>=0;TrC--)
                  {
                     if(!OrderSelect(TrC,SELECT_BY_POS))continue;
                     if(OrderSymbol()!=Symbol())continue;
                     if(OrderType()!=OP_BUY||OrderType()!=OP_SELL)continue;
                     if(OrderOpenPrice()==AskV||OrderOpenPrice()==BidV)
                     return(true);
                     Print ("Double trade zone");
                     
                  }
            }
         }
   }
   else return(false);
   
}

I would be very much thank full if you could suggest me that how could I return the value from the inner for loop to the function in this code. Is there any mistake, or am I not doing in correct way.

For what do you need all these variables? Please comment your code and say what you want to achieve.
