Average True Range Metrics

Calculation

Average True Range (ATR) metrics represent a volatility measure derived from price fluctuations over a specified period, commonly 14 periods, though adaptable for varied analytical needs. The core computation involves determining the greatest of the following: the current period’s high less the current period’s low, the absolute value of the current period’s high less the previous period’s close, and the absolute value of the current period’s low less the previous period’s close. This true range value then undergoes smoothing, typically using an exponential moving average, to generate the ATR, providing a standardized volatility indicator. Its application extends beyond simple volatility assessment, informing position sizing and stop-loss placement strategies.
