Average True Range - ATR Analysis and ATR Signals
Created and Developed by J. Welles Wilder
This indicator is a gauge of the volatility - it gauges the range of price movement for a particular price period. The ATR is a directionless technical indicator & it does not determine/figure out the direction of the Forex trend.

High ATR indicator values
High Average True Range values indicated market bottoms after a sell-off.
Low ATR readings
Low ATR values showed extended periods of sideways price movement - Price Range Bound Movement, like the ones which are found at market tops and market consolidation periods. Low ATR technical indicator values are typical for periods of sideways market movement of a long duration of time which happens at the top of the market trend and during consolidation phases.
Calculation
This technical indicator is calculated using the following formula:
- Difference between the present high and the current low
- Difference between the previous closing price and the current high
- Difference between the previous closing price and the current low
The final Average is calculated by adding these values and calculating the average.
