Bug ? - Detecting New Bar

[wpg]

Problem in detecting New Bar ( Testing using Daily Data ).

In the following code, the value of Old_Time is *always* has same the same value as New_Time.  Any idea why it is so ? 

Thanks,

Walter

   static datetime Old_Time;

   datetime New_Time[1];
   bool IsNewBar=false;

   int copied=CopyTime(_Symbol,_Period,0,1,New_Time);
   if(copied>0) // ok, the data has been copied successfully
     {
      printf ( "Bar %d, %d", Old_Time, New_Time[0]) ;
      if(Old_Time!=New_Time[0]) // if old time isn't equal to new bar time
        {
         IsNewBar=true;
         Old_Time=New_Time[0];            // saving bar time
         return true ;
        }
     }
   else
     {
      Alert("Error in copying historical times data, error =",GetLastError());
      ResetLastError();
     }
      return false;
