   if(handle>0)
   {

      Print(_BuyTotal," > ",value);
      Comment("BUY ",value);
      FileClose(handle);
   }  
   
   handle=FileOpen("buytt.dat", FILE_CSV|FILE_WRITE, ';');
   if(_BuyTotal > handle)
   {
     FileWrite(handle, _BuyTotal);
     FileClose(handle);
     Comment("A ",_BuyTotal," > ",value);
   } else {Comment("B ",_BuyTotal," > ",value);
     if(_BuyTotal == 0)
     {Comment("C ",_BuyTotal," > ",value);
       handle=FileOpen("buytt.dat", FILE_CSV|FILE_WRITE, ';');
       FileWrite(handle, _BuyTotal);
       FileClose(handle);       
     }     
   }

print(_BuyTotal > value); <<i try to print the record as this script above, always change 2 > 2, 2 > 0, 2 > 2, 2 > 0...
if(_BuyTotal > value)
