Average True Range (ATR)


A measure of volatility introduced by Welles Wilder in his book: "New Concepts in Technical Trading Systems."

The True Range indicator is the greatest of the following:

  • Current high less the current low.
  • The absolute value of the current high less the previous close.
  • The absolute value of the current low less the previous close.
  • The Average True Range is a moving average (generally 14-days) of the True Ranges.

    Wilder originally developed the ATR for commodities but the indicator can also be used for Forex. Simply put, a currency experiencing a high level of volatility will have a higher.
