Supported Indicators and Calculation Methods

The calculator can calculate 12 different variations of Average Range or Average True Range:

4 Types of Range

  • Range = high less low
  • True Range = the greatest of high less low, high less previous close, and previous close less low
  • % Range = Range divided by previous close
  • % True Range = True Range divided by previous close

3 Average Methods

  • Simple moving average
  • Exponential moving average: a = 2/(n+1)
  • Wilder's smoothing method: a = 1/n

Note: The original ATR as introduced by J. Welles Wilder Jr. is True Range + Wilder method.

You can set any period length on any of the variations.

The calculation methods are explained in chapter 4 of the PDF guide.
