ATR Percent
When reversing from short to long, the stop and reverse point is one ARC above the lowest close. When reversing a position from long to short, a trader waits for a security to close at one ARC below the highest close since they purchased the shares. In any case, a trader might want to investigate why a security has an unusually high ATR before they buy or sell.
Professionals have used this volatility indicator for decades to improve their trading results. Wilder’s method refers to the exponential smoothing technique used. Unlike a simple moving average that weighs all data points equally, Wilder’s method of using an EMA places greater weight on recent data.
What Is ATR?
The Average True Range (ATR) is an indicator used by technical traders to measure volatility. The ATR does not signal a directional bias, but instead tells us how violently price has moved across a past duration. A high ATR value represents high volatility, whilst a low ATR value represents low volatility. If the current price range is 90 (or any range resembling a skyscraper), it is unlikely the price will continue going up because the price movement has already more than doubled the average. In this case, a trader might be better off selling, shorting, or making an options trade with the stock.
Mistake 1: Using ATR for Direction #
- The price volatility indicated by the average true range can be used by traders to determine the appropriateness of a trade.
- Typically, the Average True Range (ATR) is based on 14 periods and can be calculated on an intraday, daily, weekly or monthly basis.
- Wilder originally developed the ATR for commodities, although the indicator can also be used for stocks and indices.
- Monitoring ATR provides useful insights into volatility and price movements.
- How close together the upper and lower Bollinger Bands are at any given time illustrates the degree of volatility the price is experiencing.
The ATR is commonly used as an exit method that can be applied no matter how the entry decision is made. One popular technique is known as the “chandelier exit” and was developed by Chuck LeBeau. The chandelier exit places a trailing stop under the highest high the stock has reached since you entered the trade. The distance between the highest high and the stop level is defined as some multiple multiplied by the ATR.
ATR for position sizing
When plotted, the readings form a continuous line that shows the change in volatility over time. The indicator oscillates above zero with no upper limit—higher values indicate higher volatility, while lower values suggest calmer market conditions. ATR is expressed in the same units as the asset’s price (dollars for stocks, pips for forex, points for indices).
An ATR with a longer time frame is usually a better indicator of a security’s long term future. Using fewer intervals to obtain the average will cause the ATR to produce as many signals as a shark has teeth. So if you’re worried you’ll capsize in dangerous water, remember there is safety in numbers. Price gaps and limit days can cause simple high-low ranges to be inaccurate.
Alternative Settings by Trading Style: #
A common strategy is to set the stop loss at a multiple of the ATR. For example, a trader might set the stop average true range percent loss at twice its value. This means that if the ATR is 0.5, the stop loss would be set at 1.0.
When the trader decides to sell, they place a trailing stop loss order and sets the trailing stop to .72. A trailing stop on a long position—it’s kind of like a levitating magician that helps limit loss, protect gains, and stay in a trade longer. Traders often add or subtract the ARC from a security’s close price to decide whether or not to enter, exit, or reverse a position. For short positions, they subtract the ARC from the close price. Theoretically, the constant can be any number, although the higher the constant is, the less effective the ARC will be at stopping losses.
Volatility measures the strength of the price action and is often overlooked for clues on market direction. ATR can be used to identify potential breakouts by highlighting periods of increased volatility. When values rise, it indicates that price movements are becoming more significant, which could signal an upcoming breakout.
- Traders might consider combining ATR with other indicators like moving averages or relative strength index (RSI) for more robust analysis.
- Traders can practise setting these stop-losses using a demo account before applying them to live trades.
- ATR calculates based on previous periods, so there is an inherent delay before ATR is able to signal shifts in volatility or reversals in trends.

Stop-losses are market orders that would exit a losing trade at a predetermined price. Note that ordinary stop-losses do not shield from slippage – in this case, guaranteed stop-losses may offer more protection, yet charge a fee. While the possibility of comparing the true range based volatility across different securities is characteristic of APTR, it may be equally useful when applied to a single symbol.
What does ATR tell you about a stock or market? #
Today, the commonly used ATR setting is the 14-period, but traders may prefer using different ATR values for specific purposes. Welles Wilder Jr. preferred using the 7-period ATR for his trading. This setting makes the ATR indicator more sensitive to recent price swings, allowing traders to set more dynamic stop losses.
