DESCRIPTION
The average true range (ATR) is a technical analysis indicator used to measure market volatility. The ATR was developed by J. Welles Wilder and is based on the true range of security, which is defined as the greatest of the following:
- The difference between the current high and the current low.
- The difference between the previous close and the current high.
- The difference between the previous close and the current low.
The ATR is calculated by taking the average of the true ranges over a specified period of time, typically 14 days. The resulting value is used to gauge the level of price volatility, with higher values indicating greater volatility and lower values indicating lower volatility. Traders may use the ATR to help set stop loss levels and to identify potential price breakouts.
