Key Takeaways Designed by Welles Wilder for commodity daily charts, the ADX is now used in several markets by technical traders to judge the strength of a trend. Non-trending doesn't mean the price isn't moving.

What Is the Aroon Indicator? The Aroon indicator is a two-lined technical indicator that is used to identify trend changes and the strength of a trend by using the time elapsed since a high or low. For example, the best trends rise out of periods of price range consolidation. Breakouts from a range occur when there is a disagreement between the buyers and sellers on price, which tips the balance of supply and demand.
Whether it is more supply than demand, or more demand than supply, it is the difference that creates price momentum. Breakouts are not hard to spot, but they often fail to progress or end up being a trap. However, ADX tells you when breakouts are valid by showing when ADX is strong enough for price to trend after the breakout. When ADX rises from below 25 to above 25, price is strong enough to continue in the direction of the breakout.
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 In a range, the trend is sideways, and there is general price agreement between the buyers and sellers. ADX will meander sideways under 25 until the balance of supply and demand changes again.
ADX gives great strategy signals when combined with price. First, use ADX to determine whether prices are trending or non-trending, and then choose the appropriate trading strategy for the condition. In trending conditions, entries are made on pullbacks and taken in the direction of the trend. In range conditions, trend-trading strategies are not appropriate. However, trades can be made on reversals at support long and resistance short.
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 sideways price action.
In addition, it shows when price has broken out of a range with sufficient strength to use trend-trading strategies. ADX also alerts the trader to changes in trend momentum, so risk management can be addressed. If you want the trend to be your friend, you'd better not let ADX become a stranger.

Additionally, the three lines can be shown as a separate box. The default setting for the ADX is usually 14 periods, but you can change the configuration and choose other time frames. Average directional index calculation is based on a couple of steps. These involve the calculation of the directional movement indicators both positive and negative , and calculation of the true range with a moving average or other method selected by the trader suggested by Wilder.
The last step in the calculation of ADX refers to the smoothing technique used to find the associated indicator values. The following ADX formula is applied:. Wilder also suggests other smoothing techniques that could be applied during ADX calculation, such as a moving average or exponential moving average.
Market conditions play a crucial role when defining your trading strategy and the types of technical analysis indicators and tools you apply. Consequently, you can use the average directional index to determine and confirm trending or range-bound market conditions. If you are a trend trader, the ADX indicator will be helpful for eliminating assets exhibiting range-bound conditions. Traders identify signals based on the DI crossovers strategy:. During ADX trading, you can also watch for potential signals of a possible breakout from a ranging market.
ADX can also be used when you look for potential moving average crossovers , or when the shorter moving average crosses over the longer period moving average. The average directional index can be used as a way to confirm the strength of a trend for a buy or sell crossover signal. Identifying a crossover signal while the ADX a has value above 30 indicates a continuance in the trend direction. Aside from the moving averages, you can combine the ADX with indicators such as the Fibonacci retracement, stochastic oscillators, Parabolic stop and reverse system SAR , relative strength index RSI and so on.
You can see how the ADX indicator looks when plotted on your chart by itself, or when it is set up with the positive and the negative directional indicators to identify crossovers. Another example offers an insight into the possible application of the average directional index, in terms of how you can distinguish between a range-bound or trending condition.
Let's start with an overview of how the average directional index indicator will look when plotted on a chart. The red line at the bottom of the chart represents the ADX indicator and you can see that a weak trend is identified when ADX has a value of below 20 below the white line. Alternatively, a strong trend is emerging when ADX has a value above 40 the yellow line.
On the left side of the graph, you can see that the negative DI yellow line crosses above the positive DI blue line , signalling a bearish price movement. Conversely, to the right, a bullish crossover is found when the positive DI crosses above the negative DI, which alerts for an upward price movement. An example of how you can use the ADX indicator to identify the type of market condition is presented in the next graph.
On the graph, you can see that on the left side, the ADX value is below 20, signalling a ranging market. At the end of the ranging market period, ADX progressively moves upward, reaching values above 40, which is an indicator that there is a strong trend. A higher value could mean entering the trade later. The ADX does not indicate trend direction or momentum, only trend strength. ADX will range between 0 and Generally, ADX readings below 20 indicate trend weakness, and readings above 40 indicate trend strength.
An extremely strong trend is indicated by readings above Alternative interpretations have also been proposed and accepted among technical analysts. For example it has been shown how ADX is a reliable coincident indicator of classical chart pattern development, whereby ADX readings below 20 occur just prior to pattern breakouts. The slope of the ADX line is proportional to the acceleration of the price movement changing trend slope.
If the trend is a constant slope then the ADX value tends to flatten out. Various market timing methods have been devised using ADX. One of these methods is discussed by Alexander Elder in his book Trading for a Living.
