hey guys, how do i choose the max or minimum values for an indicator in MT4? for example, i wan to find the minimum of the past five periods and have the indicator display that number. so it would go through the past five periods and choose the lowest one. does anyone have the code for this or could anyone help me out?

extern int Number_Of_Candles = 5;
extern bool Include_Current_Candle = true;

   if(!Include_Current_Candle)
   {
      SignalIndex = 1;
   }
   Comment("Current Minimum = "+GetMinimum());

  double GetMinimum()
  {
     double CurrentMinimum = Low[SignalIndex];
     for (int i=SignalIndex+1; i<SignalIndex+Number_Of_Candles; i++)
     {
        if (CurrentMinimum > Low[i])
        {
           CurrentMinimum = Low[i];
        }
     }
     return (CurrentMinimum);
