ATR Indicator Explained – What is the ATR Indicator?

How to Use the Average True Range Indicator The average true range indicator is a volatility measure of a stock's performance.

Decimal rounding can also slightly affect ATR values. Current Low less the previous Close absolute value Absolute values are used to ensure positive numbers. 

Because there must be a beginning, the first TR value is simply the High minus the Low, and the first day ATR is the average of the daily TR values for the last 14 days. To adjust the period setting, highlight the default value and enter a new setting.

Introduction 

Technical indicators are some of the most important quantitative tools used by active traders.

Current High less the current Low Method 2: Current High less the previous Close absolute value Method 3: Current Low less the previous Close absolute value Absolute values are used to ensure positive numbers.

After all, Wilder was interested in measuring the distance between two points, not the direction. If the current period's high is above the prior period's high and the low is below the prior period's low, then the current period's high-low range will be used as the True Range. This is an outside day that would use Method 1 to calculate the TR. This is pretty straightforward. Methods 2 and 3 are used when there is a gap or an inside day.

A gap occurs when the previous close is greater than the current high signaling a potential gap down or limit move or the previous close is lower than the current low signaling a potential gap up or limit move. The image below shows examples of when methods 2 and 3 are appropriate. The TR equals the absolute value of the difference between the current high and the previous close.

The TR equals the absolute value of the difference between the current low and the previous close. In fact, it is smaller than the absolute value of the difference between the current high and the previous close, which is used to value the TR. Calculation Typically, the Average True Range ATR is based on 14 periods and can be calculated on an intraday, daily, weekly or monthly basis. For this example, the ATR will be based on daily data.

Because there must be a beginning, the first TR value is simply the High minus the Low, and the first day ATR is the average of the daily TR values for the last 14 days. After that, Wilder sought to smooth the data by incorporating the previous period's ATR value.

In the spreadsheet example, the first True Range value. The first day ATR value. Subsequent ATR values were smoothed using the formula above. The spreadsheet values correspond with the yellow area on the chart below.

For those trying this at home, a few caveats apply. The real ATR formula does not kick in until day Spreadsheet values for a small subset of data may not match exactly with what is seen on the price chart. Decimal rounding can also slightly affect ATR values. On our charts, we calculate back at least periods typically much further , to ensure a much greater degree of accuracy for our ATR values.

The ATR formula is comprised of three key inputs, which is why the word "true" is in the title, because these three inputs provide a more holistic view of a stock's trading activity. How to Calculate the Average True Range The average true range is comprised of three inputs, which are helping identify the volatility of a security. In order to calculate the average true range, you take the average of each true range value over a fixed period of time.

For more information on average true range calculators, excel formulas and history, below are a list of great sources: Average True Range Chart Average True Range of Apple on a 5-minute chart The average true range is an off-chart indicator, meaning you will plot the indicator above or below the price chart. For me, I prefer to have the average true range below both the price chart and volume indicator.

The one key differential for the average true range is that the indicator will experience extreme highs and lows based on the volatility independent of price direction. How to Use the Average True Range Indicator The average true range indicator is a volatility measure of a stock's performance. Below are the key ways traders use the indicator: Drawdowns are what kills a trader's ability to consistently earn over the long haul and creates enormous emotional pain and turmoil. Drawdowns are a result of two factors: One could argue that if you get number 1 right, the volatility is irrelevant; however, these two elements are not always mutually exclusive.

I quickly realized that I needed a common method for not only identifying great setups, but also a way to rate a stock's volatility. To this aim, I began researching the average true range indicator. The problem I had with the ATR is that the indicator's value was different for each stock. Higher priced stocks had higher ATRs versus the low priced momentum players. Using the above chart example, take the period ATR divided by the closing price of Apple on the 5-minute chart.

On the surface, this. Now, let us apply the same math to a more volatile stock. As you begin to analyze the volatility ratio of stocks, you will begin to identify the stocks that have just the right mix of volatility for your trading appetite. For you, your volatility range could be. You cannot evaluate the 5-minute volatility ratio and then compare that to a daily volatility ratio, even if it is the same stock.

The common thread is the timeframe; otherwise, you are comparing apples to oranges. This is a basic concept, but easier said than done. In theory, this equates to diminishing price movement, which implies that either the buying or the selling interest is tapering. So, how do we use the average true indicator as an early sign that the stock is likely going to have a change in trend, so we know where to execute a stop loss to exit a trade?

For newbie traders, this explanation will get a bit muddy, but do the best you can to stay with me. The below chart is of Apple from the time period of late April through early May. Looking at the ATR, do you have an idea of where to place the average true range stop loss?

The key of course is making sure your multiplier for the target price is greater than the stop loss, so over a series of trades you have a greater likelihood of turning a profit.

In the Apple example above you would take the ATR value of. This would provide you a target price of.
