Average True Range ATR Overview, How to Calculate and Interpret
Thus futures traders and analysts typically use one method (ATR) to calculate volatility, while stock traders and analysts typically use standard deviation of log price ratios. The indicator is calculated on the basis of the so-called true ranges. It uses the absolute value of the current high less the previous close or the absolute value of the current low less the previous close. While https://www.bigshotrading.info/blog/exchange-traded-funds-etf-what-do-you-need-to-know/ does track volatility, it doesn’t measure or forecast which way a security’s price is likely to move next.
How do you read an ATR indicator?
Reading the ATR indicator is not complicated: a higher ATR means increased volatility, while a lower ATR signals lower volatility. However, remember that ATR does not give signals about the potential trend direction – it only shows what is happening with the price volatility.
Below, you can see that the ATR line rises as volatility increases (in either price direction). With ATR, traders try to determine an optimal period to trade volatile swings. They should then calculate the True Range of those time periods (for example, of 14 days), and find the average of them. This final number is the Average True Range and shows the average price movement for the time period involved. Long-term traders use ATR technical analysis to tune out market noise by accounting for daily volatility that might otherwise prompt them to close their positions early.
How To Calculate ATR?
One example is when there is a sudden increase in ATR, some traders might believe it is confirming an old upwards or downwards trend, which can be false. Moreover, an investor should also review historical readings of average true range to examine the current price movements. The value of the average true range changes and generally falls during the day.
What is the formula for ATR?
The ATR calculation starts with selecting the True Range based on one easy method. It is the largest value of (current high – current low), Absolute(current high – previous close), Absolute(current low – previous close). Subsequently, Current ATR is the output of “[(Prior ATR x(n-1)) + Current TR]/n”.
In the spreadsheet example, the first True Range value (.91) equals the High minus the Low (yellow cells). The first 14-day ATR value (.56) was calculated by finding the average of the first 14 True Range values (blue cell). The spreadsheet values correspond with the yellow area on the chart below; notice how ATR surged as QQQ plunged in May with many long Average True Range candlesticks.

True Range takes into account the most current period high/low range as well as the previous period close (if needed).
ATR indicator for MT4
A rule of thumb is multiplying the current ATR by two to determine a prudent stop-loss point. So, if you’re going long, you might place a stop-loss at a level twice the ATR lower than the entry price. If you’re going short, you might place a stop-loss at a level twice the ATR above the entry price. So, while the ATR can’t tell us the direction of the breakout, it can be added to the closing price and used as a buy signal whenever the price is seen trading above that value the next day. To sum up, a change in volatility occurs whenever the price closes more than an ATR value above the most recent close.
- The indicator does not provide an indication of price trend, simply the degree of price volatility.
- Many day traders use the ATR to figure out where to put their trailing stop-loss.
- Trading is well known for its volatility, especially with cryptocurrencies.
- The ATR moves up and down as the price movement becomes larger or smaller.

- A sharp decline or rise results in high average true range values.
This will ensure that all aspects of price action, trend and market volatility are covered for a comprehensive trading strategy. The ATR technical indicator is a key tool for traders looking to understand volatility patterns in a particular market and make informed trading decisions. Traders use it to evaluate an asset’s price volatility in combination with other technical analysis indicators and tools to decide when it is appropriate to enter and exit trades. Keeping volatility in sight is important for active day traders who may seek to capitalize on market movements to increase returns or avoid losses.
About ATR indicator
The ATR may be used by market technicians to enter and exit trades and is a useful tool to add to a trading system. It was created to allow traders to more accurately measure the daily volatility of an asset by using simple calculations. The indicator does not indicate the price direction; instead, it is used primarily to measure volatility caused by gaps and limit up or down moves. The ATR is relatively simple to calculate, and only needs historical price data. The ATR is then a moving average of the true ranges, often using 14 days. More trading signals could also be generated using a time period smaller than 14 days.
