Wilder originally developed the ATR for commodities, although the indicator can also be used for stocks and indices.1 Simply put, a stock experiencing a high level of volatility has a higher ATR, and a lower ATR indicates lower volatility for the period evaluated. The ATR may be used by market technicians to enter and exit trades and is a…
The first step in calculating ATR is to find a series of true range values for a security. The price range of an asset for a given trading day is its high minus its low. To find an asset’s true range value, you first determine the three terms from the formula. Suppose that XYZ’s stock…
The formula to calculate ATR for an investment with a previous ATR calculation is : \begin{aligned}&\frac{ \text{Previous ATR} ( n – 1 ) + \text{TR} }{ n } \\&\textbf{where:} \\&n = \text{Number of periods} \\&\text{TR} = \text{True range} \\\end{aligned}nPrevious ATR(n−1)+TRwhere:n=Number of periodsTR=True range If there is not a previous ATR calculated, you must use: \begin{aligned}&\Big ( \frac{ 1 }{…
The average true range (ATR) is a technical analysis indicator introduced by market technician J. Welles Wilder Jr. in his book New Concepts in Technical Trading Systems that measures market volatility by decomposing the entire range of an asset price for that period.1 The true range indicator is taken as the greatest of the following: current high…

The best profits come from trading the strongest trends and avoiding range conditions. ADX not only identifies trending conditions, it helps the trader find the strongest trends to trade. The ability to quantify trend strength is a major edge for traders. ADX also identifies range conditions, so a trader won’t get stuck trying to trend trade in…
Conversely, it is often hard to see when price moves from trend to range conditions. ADX shows when the trend has weakened and is entering a period of range consolidation. Range conditions exist when ADX drops from above 25 to below 25. In a range, the trend is sideways, and there is general price agreement between the…
Price is the single most important signal on a chart. Read price first, and then read ADX in the context of what price is doing. When any indicator is used, it should add something that price alone cannot easily tell us. For example, the best trends rise out of periods of price range consolidation. Breakouts from a…
The series of ADX peaks are also a visual representation of overall trend momentum. ADX clearly indicates when the trend is gaining or losing momentum. Momentum is the velocity of price. A series of higher ADX peaks means trend momentum is increasing. A series of lower ADX peaks means trend momentum is decreasing. Any ADX peak…
ADX values help traders identify the strongest and most profitable trends to trade. The values are also important for distinguishing between trending and non-trending conditions. Many traders will use ADX readings above 25 to suggest that the trend is strong enough for trend-trading strategies. Conversely, when ADX is below 25, many will avoid trend-trading strategies. ADX Value Trend Strength…
