Returned value

The shift of the maximum value over a specific number of bars or -1 if error. To check errors, one has to call the GetLastError() function.

Example:

  double val;
//--- calculating the highest value on the 20 consecutive bars in the range
//--- from the 4th to the 23rd index inclusive on the current chart
   int val_index=iHighest(NULL,0,MODE_HIGH,20,4);
   if(val_index!=-1) val=High[val_index];
   else PrintFormat("Error in call iHighest. Error code=%d",GetLastError());
