Average True Range (ATR)

When it comes to analyzing financial markets, the Average True Range (ATR) is a valuable tool that traders and investors rely on. ATR helps gauge market volatility and can be a crucial factor in making informed decisions. In this article, we’ll delve into the concept of ATR and its significance in financial analysis.

What is Average True Range (ATR)?

ATR is a technical indicator used primarily in technical analysis to measure the degree of price volatility in a financial instrument, such as a stock, currency pair, or commodity. It was developed by J. Welles Wilder Jr. and introduced in his 1978 book, “New Concepts in Technical Trading Systems.”

Calculating ATR

ATR is calculated using a straightforward formula:

ATR = [(Prior ATR * 13) + Current TR] / 14
  • Prior ATR: The previous ATR value.
  • Current TR: The current True Range, which measures the market’s true volatility.

This calculation uses a 14-period exponential moving average (EMA) to smooth out the data, making it easier to interpret.

Interpreting ATR

Understanding ATR is crucial for traders and investors because it provides insights into:

  • Market Volatility: Higher ATR values indicate increased volatility, while lower values suggest calmer market conditions.
  • Setting Stop Losses and Take Profits: ATR can help determine appropriate levels for setting stop-loss and take-profit orders, allowing traders to manage risk more effectively.
  • Position Sizing: ATR can be used to adjust the size of positions based on market volatility. In volatile markets, smaller positions may be preferred to limit potential losses.

ATR in Action

Let’s illustrate how ATR works with a practical example:

Suppose you’re considering two stocks, Company A and Company B, for investment. Company A has an ATR of 2.5, while Company B has an ATR of 0.8.

  • Company A’s higher ATR suggests greater price fluctuations, which may indicate more significant profit potential but also increased risk.
  • Company B’s lower ATR indicates a more stable price movement, making it a potentially safer choice but with potentially lower profit opportunities.


In summary, the Average True Range (ATR) is a valuable tool for traders and investors in assessing market volatility, setting risk management parameters, and making informed decisions. By incorporating ATR into your trading strategy, you can better navigate the dynamic world of financial markets.

Remember, understanding ATR is just one piece of the puzzle in the complex world of trading and investing. Always conduct thorough research and consider multiple factors before making any financial decisions.
