Average True Range (ATR)
The Average True Range (ATR) is a technical analysis indicator, developed by J. Welles Wilder Jr., used to measure market volatility. It quantifies the degree of price movement by taking the average of the ‘true range’ over a specified number of periods. A higher ATR value indicates higher market volatility, while a lower ATR signifies a period of lower volatility or consolidation. Importantly, ATR does not provide an indication of price direction, only the magnitude of its movement.
