Warning: Possible loss of data due to type conversion - in conjunction with array

New comment
 

Hi there,

I'm migrating an expert advisor from MQL4 to MQL5.


   int TTTradeState[99];
   uint PosTotal;
   ulong PosMagic;
   
   PosTotal=PositionsTotal();
   
   for ( uint all_positions = 0; all_positions < PosTotal; all_positions++ ) { 
      PosMagic = PositionGetInteger(POSITION_MAGIC);
      TTTradeState[PosMagic] = 3;
   }


In line

   TTTradeState[PosMagic] = 3;

I get a warning "Possible loss of data due to type conversion" and I don't know why.

I guess that PosMagic is expected to be datatype integer, but it's ulong. I don't know a way to convert from integer to ulong, so I've got no chance to check if my assumption is right.

Any help would be very welcome.


Best regards

Jorg

 

I found it:


...

   PosTotal=PositionsTotal();
   
   for ( uint all_positions = 0; all_positions < PosTotal; all_positions++ ) { 
      PosMagic = PositionGetInteger(POSITION_MAGIC);
      int intPosMagic = (int)PosMagic;
      TTTradeState[intPosMagic] = 3;
   }

Inserting line

      int intPosMagic = (int)PosMagic;

solved the problem. No more warning.
