A comprehensive overview of ATR indicator in trading
Introduction
Technical analysis is one of the fundamental aspects of stock market investing. Average True Range (ATR) is one of several technical analysis indicators that can help you measure market volatility. So, what is the ATR indicator and its various aspects? Let’s find out about them in this blog.
What is an ATR indicator?
ATR reflects the average of the true ranges observed over a specified timeframe. It’s designed to gauge volatility while considering any price gaps. This indicator, pioneered by J. Welles Wilder, utilises a calculation based on 14 periods, applicable across various time frames. These could be intraday, daily, weekly, or monthly.
Wilder developed ATR primarily with commodities and daily price movements in mind. He recognised that commodities are more volatile than stocks and that the former often experience gaps or limit moves.

In commodities, the opening price significantly differs from its previous close. Traditional volatility formulas rely heavily on high-low ranges and overlook such occurrences. Hence, Wilder devised the ATR indicator strategy to capture this essential aspect of volatility accurately.
ATR indicator formula
The formula for ATR is as follows:
ATR = (Previous ATR X (N – 1) + TR) / N, where:
- N is the number of periods, usually 14
- TR is the true range
The calculation entails subtracting prices to determine the true range and ATR. Note that the volatility from these calculations is constant even when historical prices are adjusted by adding or subtracting a constant value from each price point.
Advantages of ATR
Using the ATR indicator strategy in trading spells multiple benefits. These include:
- Helps measure volatility
ATR gives you a reliable measure of volatility. It helps you gauge potential price movements. Higher ATR values reflect higher volatility. On the other hand, lower values suggest lower volatility. Knowing volatility can help you tailor your trading strategy accordingly.
- Helps set stop loss and profit targets
Understanding market volatility through ATR can help in risk management. It enables you to set appropriate stop-loss and profit targets, adjusting them as the market conditions change. This proactive approach significantly brings down the risk of incurring substantial losses, making ATR an invaluable tool in your trading arsenal.
- Not influenced by emotions
Unlike emotional investing, ATR operates purely on mathematical calculations, providing you with objective data. This is a key advantage, as it helps you formulate risk management strategies based on facts rather than emotions. Emotional decision-making in trading and investing often backfires and doesn’t yield the desired results.
- Useful for trend-following traders
A rising ATR signals heightened price volatility and shows the potential strengthening of a market trend. If you are a trend-following trader, this serves as a valuable confirmation tool. It empowers you to make more informed decisions based on evolving market conditions.
Observing an uptick in ATR can help you gain confidence in a trend’s momentum. This allows you to align your strategies accordingly and seize opportunities on favourable price movements.
Limitations of ATR indicator
ATR trading has its limitations too. These include:
- A lagging indicator
Like many other technical indicators, ATR is a lagging indicator. It means it relies on past price data. While it does provide valuable insights into historical volatility, it may not always accurately predict future price movements.
- Can generate false signals
ATR can generate false signals, especially when markets are choppy. Therefore, you need to use it in conjunction with other technical indicators for an accurate overview and to ensure there are no false signals.
- Can be complex
Understanding ATR and its associated calculations can be a significant challenge if you are new to trading and technical analysis. The ATR indicator strategy’s intricacies often require dedicated learning and practical application. This process may take considerable time, and you may need guidance to navigate it effectively.
- Overlooks insights about other essential factors
While ATR provides valuable insights into volatility, it alone does not comprehensively analyse other crucial aspects of trading. These include trend direction, market sentiment, or the potential impact of news events. To trade successfully, having a holistic understanding of all these factors is crucial.
In conclusion
Calculating ATR and incorporating it into your trading strategies can help you manage risk more effectively. However, you must recognise ATR’s limitations and use it alongside technical indicators for comprehensive market analysis.
