ATR Average True Range Stop Loss Calculator


Calculating the Average True Range (ATR) is essential for traders in assessing market volatility and determining appropriate stop-loss levels. To streamline this process, a simple yet effective ATR calculator can be implemented.

How to Use

  1. Input the high, low, and close prices for a given period.
  2. Click the “Calculate” button to obtain the ATR value.


The ATR calculation involves finding the average of true range values over a specified period. The true range (TR) is the greatest of the following:

  • Current high minus the current low
  • Absolute value of the current high minus the previous close
  • Absolute value of the current low minus the previous close

The ATR is then calculated as the exponential moving average of the true range over the specified period.

Example Solve

Suppose we want to calculate the ATR for a stock with the following daily price data:

  • High: $50
  • Low: $45
  • Close: $48

Using a 14-day period, the ATR can be calculated as follows:

  1. True Range = max(50 – 45, |50 – 48|, |45 – 48|) = 5
  2. ATR = EMA(True Range, 14)


Q: What is the significance of ATR in trading?
A: ATR helps traders gauge market volatility, enabling them to set appropriate stop-loss levels and determine position sizing.

Q: How often should ATR be recalculated?
A: It depends on the trading strategy and timeframe. Typically, ATR is recalculated at the beginning of each trading session or periodically throughout the day.

Q: Can ATR be used in conjunction with other technical indicators?
A: Yes, ATR is often used alongside indicators like moving averages and Bollinger Bands to make more informed trading decisions.


Implementing an ATR calculator simplifies the process of determining optimal stop-loss levels based on market volatility. By inputting price data and utilizing the ATR formula, traders can make more informed decisions and manage risk effectively.
