## Average True Range

The Average True Range (ATR) is a technical indicator that measures market volatility. It calculates the average range between high and low prices over a specified period, helping traders gauge price fluctuations.

To calculate the Average True Range (ATR), first determine the following: the current day’s high minus the current day’s low, the absolute value of the current day’s high minus the previous day’s close, and the absolute value of the current day’s low minus the previous day’s close. Use the highest of these values to determine the True Range (TR). Then, average this result over a set number of periods, typically 14 days. This calculation helps traders adjust their strategies based on market volatility.

## How To Calculate ATR?

To calculate the Average True Range (ATR), use the following formula: ATR = (Current High – Current Low, Current High – Previous Close, Current Low – Previous Close). The highest value is selected and averaged over a specified period, typically 14 days.

To calculate ATR step-by-step:

1. Determine True Range (TR)
• Calculate today’s high minus today’s low.
• Calculate the absolute value of the current high minus the previous close.
• Calculate the absolute value of the current low minus the previous close.
1. Select the highest value from the above three calculations as the True Range (TR).
2. Average the True Range values over a specific number of periods, typically 14 days, to get the ATR.

Suppose a stock has the following data for a day

• Current High: ₹120
• Current Low: ₹110
• Previous Close: ₹115

To Calculate

• Current High – Current Low: ₹120 – ₹110 = ₹10
• Current High – Previous Close: ₹120 – ₹115 = ₹5
• Current Low – Previous Close: ₹110 – ₹115 = ₹5 (absolute value is ₹5)

The True Range (TR) is the highest value, which is ₹10. If you calculate this for 14 days and then average the values, you get the ATR.

## Average True Range Strategy

The Average True Range (ATR) strategy involves using ATR values to make trading decisions. Traders use ATR to set stop-loss levels and identify potential entry and exit points based on market volatility. To implement an ATR strategy comprehensively:

• Set Stop-Loss Levels: Use ATR to determine appropriate stop-loss levels. For instance, set the stop-loss at 1.5 times the ATR value below the entry price for a long position.
• Identify Entry and Exit Points: Use ATR to identify potential entry and exit points by observing changes in volatility. Higher ATR values indicate increased volatility, suggesting more cautious trading.
• Trailing Stop-Loss: Adjust stop-loss levels dynamically as the ATR value changes. This helps lock in profits while accommodating market fluctuations.
• Position Sizing: Adjust your position sizes based on ATR values to manage risk. Larger ATR values indicate smaller position sizes to mitigate volatility risk.
• Combine with Other Indicators: Use ATR in conjunction with other technical indicators, such as moving averages or RSI, to confirm trading signals and improve decision-making accuracy.

Suppose a trader is analyzing Infosys stock with an ATR of ₹15. If the trader enters a long position at ₹1000, they might set a stop-loss at 1.5 times the ATR below the entry price: ₹1000 – (1.5 * ₹15) = ₹977.5. This helps manage risk based on market volatility.

## What Is A Good Average True Range?

A good Average True Range (ATR) depends on the security being traded and the market conditions. Generally, higher ATR values indicate greater volatility, while lower ATR values suggest lower volatility.

A good ATR value is relative to the specific asset and its historical volatility. For instance, an ATR of ₹10 might be considered high for a low-volatility stock but low for a highly volatile stock. Traders should compare the ATR value to the asset’s past performance to determine its significance. Using ATR, traders can adjust their strategies to align with the current market conditions, ensuring they set appropriate stop-loss levels and position sizes.

For a stock like TCS, if the ATR is ₹20, it indicates a moderate level of volatility. Traders can use this information to set stop-loss levels and adjust their trading strategies accordingly, ensuring they are adequately protected against market fluctuations.

The main advantage of using the Average True Range (ATR) is that it helps traders measure market volatility. This enables better decision-making regarding stop-loss levels and position sizes, enhancing risk management. Other advantages of using ATR include:

• Improves Risk Management: ATR provides a clear measure of market volatility, allowing traders to set appropriate stop-loss levels and manage risk more effectively. This helps protect against sudden market movements.
• Adaptable to Different Markets: ATR can be used across various financial markets, including stocks, forex, and commodities. This versatility makes it a valuable tool for diverse trading strategies.
• Assists in Position Sizing: By understanding volatility through ATR, traders can adjust their position sizes accordingly. Higher volatility may lead to smaller positions, reducing exposure to risk.
• Enhances Trading Strategies: ATR can be combined with other technical indicators to create more robust trading strategies. It helps confirm signals and provides additional context for trading decisions.
• Identifies Market Conditions: ATR helps identify whether a market is experiencing high or low volatility, which can influence trading strategies. Traders can use this information to adjust their approach based on current market conditions.

## Limitations of ATR

The main limitation of the Average True Range (ATR) is that it does not indicate the direction of the market. It only measures volatility, which means traders must use it alongside other indicators to make informed decisions. Other limitations include:

• Lagging Indicator: ATR is based on historical price data, making it a lagging indicator. It reflects past volatility rather than predicting future market movements.
• Not a Standalone Tool: While the ATR is useful, it should not be the sole indicator used in trading strategies. It works best when used alongside other indicators, enhancing the understanding of market dynamics.
• Ignores Market Trends: ATR focuses solely on volatility and does not account for market trends. Traders need additional tools to understand the overall market direction and sentiment.

## Average True Range – Quick Summary

• The Average True Range (ATR) is a technical analysis tool used to measure market volatility by calculating the average range between the highest and lowest prices over a specific period.
• The Average True Range (ATR) calculates the average range between high and low prices over a specified period, helping traders gauge price fluctuations.
• To compute the ATR, you need to find three values: the difference between the highest and lowest prices of the current period, the difference between the current highest price and the previous period’s closing price, and the difference between the current lowest price and the previous period’s closing price. Use the highest value and average it over a set period, typically 14 days.
• The ATR strategy involves using ATR values to set stop-loss levels and identify potential entry and exit points based on market volatility.
• A good ATR value depends on the security and market conditions, indicating greater volatility with higher values and lower volatility with lower values. Traders compare ATR to historical volatility to adjust strategies.
• The main advantage of ATR is that it helps traders measure market volatility, improving decision-making regarding stop-loss levels and position sizes, enhancing risk management.
