Guide to Average True Range (ATR) Are Calculated?

9 minutes read

The Average True Range (ATR) is a popular technical indicator used in financial markets to measure volatility. It provides traders and investors with insights into the expected price movement of a security over a specific time period. The ATR is calculated using a specific formula.


To begin calculating the ATR, the True Range (TR) needs to be determined. The True Range is the greatest value among the following three calculations:

  1. Current high minus the current low.
  2. Absolute value of the current high minus the previous close.
  3. Absolute value of the current low minus the previous close.


Once the True Range is obtained over a chosen period (usually 14 days), the Average True Range can be calculated by taking the average of the True Range values.


To understand this better, let's assume we are calculating the ATR for a stock over a 14-day period. The first step would be to determine the True Range for each of the 14 days using the above formula. Once all the True Range values are obtained, their average is calculated to determine the ATR.


The ATR is typically displayed as a line chart alongside the price chart. Its value represents the average distance between the high and low prices over the specified time period. A higher ATR indicates greater volatility, while a lower ATR suggests lower volatility.


Traders and investors use the ATR to make various decisions. It can help set stop-loss levels, determine position sizes, identify potential trend reversals, and assess the overall market conditions. By understanding the level of volatility, traders can adjust their strategies accordingly and make more informed trading decisions.


Overall, the ATR is a valuable tool for analyzing market volatility and is widely used by technical analysts in different financial markets, such as stocks, commodities, and currencies.

How can the ATR be used in combination with other indicators?

The Average True Range (ATR) is often used in combination with other indicators to enhance trading analysis and decision-making. Here are some ways in which ATR can be used in conjunction with other indicators:

  1. Trend confirmation: The ATR can be used alongside trend-following indicators like moving averages or trend lines to confirm whether a trend is strong or weak. If the ATR value is high, it suggests a strong trend, while a low ATR value indicates a weaker trend.
  2. Volatility-based stop-loss levels: Traders can use the ATR to set their stop-loss levels based on market volatility. By multiplying the ATR value by a certain multiple, they can set stops that adjust dynamically with changing market conditions.
  3. Entry and exit points: ATR can be combined with other oscillators or technical indicators to identify potential entry or exit points. For example, traders may look for a combination of high ATR values and oversold/overbought conditions on a Relative Strength Index (RSI) to signal a buying or selling opportunity.
  4. Breakout strategies: ATR can be used to identify potential breakout levels. Traders may look for instances where the ATR is increasing, indicating higher volatility, and combine it with indicators like Bollinger Bands or a Donchian channel to confirm breakout signals.
  5. Volatility-based position sizing: ATR can help determine position sizes based on market volatility. By adjusting the position size according to the ATR value, traders can allocate more capital to high-volatility assets and reduce exposure to low-volatility assets.


It's important to note that the specific combination of indicators will depend on individual trading strategies and preferences. Traders should thoroughly backtest any combined strategy and consider risk management principles before using it in live trading.


What are some common misconceptions about the ATR indicator?

  1. A common misconception about the Average True Range (ATR) indicator is that it can accurately predict future price movements. While the indicator provides information about the volatility of an asset, it does not give direct signals or predictions about the direction of price.
  2. Another misconception is that higher ATR values always indicate bullish or bearish trends. In reality, the ATR reflects the magnitude of price movements, but it cannot confirm whether the price will move upwards or downwards.
  3. Some traders mistakenly believe that the ATR indicator can set specific entry or exit points for trades. However, the ATR is primarily used to determine the appropriate levels of stop-loss and take-profit orders based on the volatility of the market.
  4. It is also a misconception that the ATR can be compared across different assets or markets to gauge their volatility. The ATR value depends on the specific price range and movements of an individual asset, so comparing ATR values between different assets may not provide accurate insights.
  5. Some traders mistakenly believe that a decrease in ATR values signifies a decrease in volatility, while an increase indicates higher volatility. However, the ATR is a relative indicator that measures the average volatility over a specific period rather than an absolute measure of volatility.


Overall, it is important to understand that the ATR indicator is a tool for assessing volatility and determining appropriate stop-loss and take-profit levels, rather than providing direct predictions or signals for trading decisions.


Is the ATR useful for long-term investors?

The Average True Range (ATR) is a technical indicator commonly used to measure market volatility. While it can be useful for short-term traders to determine stop-loss levels and position size, it may not be directly applicable for long-term investors. Long-term investors typically focus on fundamental analysis to determine a stock's value and make investment decisions based on factors such as financial performance, industry trends, and competitive positioning. While monitoring market volatility is important, long-term investors usually prioritize the long-term prospects and growth potential of companies, and may also consider factors such as dividends, management quality, and macroeconomic trends.


How does the ATR differ from average directional index (ADX)?

The Average True Range (ATR) and Average Directional Index (ADX) are both indicators used in technical analysis to measure market volatility and determine the strength of trends, but they serve different purposes and have different calculations.

  1. Calculation:
  • ATR: The ATR is calculated by measuring the average of the true range over a specific period. The true range is the greatest value among three possibilities: the current high minus the current low, the absolute value of the current high minus the previous close, and the absolute value of the current low minus the previous close.
  • ADX: The ADX is calculated by measuring the difference between two smoothed moving averages of the directional movement index (DMI). The DMI consists of two components: the Positive Directional Index (+DI) and the Negative Directional Index (-DI). The ADX represents the average difference between these two components.
  1. Purpose:
  • ATR: The ATR primarily measures market volatility. It helps traders and analysts in setting stop-loss levels, determining position sizing, and understanding potential price ranges.
  • ADX: The ADX primarily measures the strength of trends. It helps traders and analysts identify whether a market is trending or ranging and provides an indication of the trend's strength.
  1. Interpretation:
  • ATR: Higher ATR values indicate increased volatility, while lower values signal reduced volatility. Traders use the ATR to determine how much potential price movement they should expect.
  • ADX: A rising ADX indicates a strengthening trend, while a falling ADX suggests a weakening trend or a non-trending market. Traders use the ADX to determine whether to enter or exit a trade and to measure the trend's strength.


In summary, while both the ATR and ADX are indicators used to measure market conditions, the ATR primarily focuses on volatility, while the ADX focuses on trend strength.


What is a standard deviation and how is it related to the ATR?

Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a dataset. It represents the average distance between the values in the dataset and the mean value. In other words, it indicates how spread out the values are from the mean.


Average True Range (ATR), on the other hand, is a technical analysis indicator used primarily in measuring market volatility. It calculates the average range between the high and low prices over a specified period.


The relationship between standard deviation and ATR lies in the calculation methodology. The ATR is actually derived from the standard deviation of price ranges. The ATR takes into account the true ranges (high-low prices) over a defined period and uses the standard deviation formula to determine the volatility.


While the standard deviation provides an absolute measure of dispersion, the ATR is more concerned with measuring volatility or price movement. By calculating the ATR based on the standard deviation of price ranges, it helps traders and analysts gauge the market's volatility levels and make decisions accordingly.
