ATR - Average True Range

Printer-friendly versionPDF version

The Average True Range Indicator was developed by Welles Wilder to work with the commodity industry. The purpose of the ATR is to recognize the level of volatility in a market.

Volatility is a measurement of the change in price over a given period. It is often expressed as a percentage and computed as the annualized standard deviation of the percentage change in daily price.

When a market is going sideways, it typically exhibits low volatility and is difficult to trade. A market with higher volatility is typically trending better which would produce more opportunities to get into a trade. If a market’s volatility is too high, traders find that the market is too erratic, and it becomes difficult to trade. In using the ATR, traders hope to measure the level of volatility to help them interpret the different markets they are watching. It is important to remember to consult other indicators or analysis so that you are not relying on only one indicator to determine market entry or exit.

The ATR’s value is a measurement of the market volatility. When a market is increasing in volatility the ATR will have a higher value, and when the market is decreasing in volatility the ATR will have a lower value.


The ATR is a moving average of the True Ranges defined below. The default period interval in Track ‘n Trade Live is 5 days. The ATR is calculated based on the largest of the three distances from the following:

Today’s HIGH to today’s LOW
Yesterday’s CLOSE to today’s HIGH
Yesterday’s CLOSE to today’s LOW
