Average True Range (ATR)

The Average True Range (ATR) is a technical analysis indicator developed by J. Welles Wilder. It measures the market’s volatility by calculating the average range of price movements over a specific period. Unlike other indicators that focus on price direction, the ATR provides information about the degree of price movement, helping traders assess how much the price of an asset might fluctuate.

Key Features of the ATR Indicator:

1. Volatility Measurement: The ATR measures the volatility of an asset. Higher ATR values indicate increased volatility, while lower ATR values suggest reduced market volatility.

2. True Range Calculation: The ATR is based on the concept of True Range (TR), which accounts for gaps and limit moves, making it a more accurate measure of volatility.

3. No Trend Direction: The ATR does not provide information on trend direction. It is a neutral indicator that solely focuses on the magnitude of price movement.

How to Calculate the ATR

The ATR calculation involves these steps:

1. True Range (TR): The True Range is the largest of the following three values:

   • Current high minus the current low.
   • Current high minus the previous close (absolute value).
   • Current low minus the previous close (absolute value).

2. Average True Range: The ATR is calculated by taking the moving average of the True Range over a specified number of periods (usually 14 periods).

   The formula for ATR is:

   • ATR = Moving Average (True Range)
