They should then calculate the true range of those time periods (for example, of 14 days), and find the average of them. This final number is the average true range and shows the average price movement for the time period involved. The ATR is a volatility indicator which means that it measures price fluctuations. This is in stark contrast to other trend and momentum indicators such as the RSI or the STOCHASTIC indicator.
ATR for position sizing
Moving average convergence divergence (MACD) is used to point out potential entry and exit points for trades a long term and short term exponential moving average. The ATR adjusts to changing market conditions by incorporating recent price data into its calculations. Since it’s a rolling measure of the true range over a specified period, the most recent data points have a more significant impact on its value. If the market becomes more volatile, this will be reflected in larger true range values, which will then increase the ATR.

Interestingly, different markets may provide different characteristics when it comes to the manifestation of volatility during trending markets. The price was in a bullish trend during the first highlighted phase. The STOCHASTIC (lower indicator window) was above the 80 level, confirming a strong bullish trend.

The average true range values are useful for entry and exit triggers. However, they should not depend only on the average true range, rather it should be used along with a strategy to determine suitable trades. An average true range value is the average price range of an investment over a period. So if the ATR for an asset is $1.18, its price has an average range of movement of $1.18 per trading day.
