The more volatility in a large move, the more interest or pressure there is reinforcing that move. This can be used as a way to gauge the underlying strength of the move. In that case, the ATR will be on the rise. For example, if a security's price makes a move or reversal, either Bullish or Bearish, there will usually be an increase in volatility. Instead, it is most useful in measuring the strength of a move. What to look for Measuring the Strength of a MoveĪs previously stated Average True Range does not take into account price direction, therefore it is not used as an active indicator to predict future moves. ATR can be used with varying periods (daily, weekly, intraday etc.) however daily is typically the period used.The look back period to use for the ATR is at the trader's discretion however 14 days is the most common.The way to interpret the Average True Range is that the higher the ATR value, then the higher the level of volatility. The basicsĪverage True Range is a continuously plotted line usually kept below the main price chart window. By default on TradingView the ATR is a Relative Moving Average (RMA) of the True Range, but the smoothing type can be changed to SMA, EMA or WMA in the settings. *Once you have the True Range, the Average True Range can be plotted. Therefore there should be no negative numbers. *Absolute Value is used because the ATR does not measure price direction, only volatility. The Absolute Value (abs) of the Current Period Low minus (-) The Previous Period Close true range = max The Absolute Value (abs) of the Current Period High minus (-) The Previous Period Close The True Range is the largest of the following: The Current Period High minus (-) Current Period Low There are three calculation which need to be completed and then compared against each other. True Range takes into account the most current period high/low range as well as the previous period close if necessary. To calculate the ATR, the True Range first needs to be discovered. Much like the indicators mentioned, the ATR is still widely used and has great importance in the world of technical analysis. The book was published in 1978 and also featured several of his now classic indicators such as The Relative Strength Index, Average Directional Index and the Parabolic SAR. Welles Wilder created the ATR and featured it in his book New Concepts in Technical Trading Systems. Rather, it is a metric used solely to measure volatility, especially volatility caused by price gaps or limit moves. Unlike many of today's popular indicators, the ATR is not used to indicate the direction of price. The Average True Range (ATR) is a tool used in technical analysis to measure volatility.
