ADX Indicator in Trading: Strategy & Calculation

Average Directional Index

ADX values range between 0 and 100, where high numbers imply a strong trend and low numbers imply a weak trend. Many traders believe ADX readings above 25 indicate a strong enough trend for trend-trading strategies.

What is the ADX used for?

Firstly, the ADX is used to determine if a market is even trending rather than simply fluctuating within a range. Secondly, to determine the trend’s strength in a trending market. Finally, it is also often used, as other momentum indicators are, to indicate a potential market reversal or trend change.

The red arrow on the chart indicates the point of opening the trade. ADX Crossover Average Directional Index shows when the main index line crosses the set level with an arrow.

Calculating the Average Directional Movement Index (ADX)

Technical analysis focuses on market action — specifically, volume and price. Technical analysis is only one approach to analyzing stocks. When considering which stocks to buy or sell, you should use the approach that you’re most comfortable with. However, there are other cons of using the indicator. First, it is a relatively difficult indicator to calculate.

  • The information provided by, Inc. is not investment advice.
  • The DMI is calculated by subtracting minus DM from plus DM and then divide the result by the sum of the two.
  • For example, if the +DI line crosses above the -DI line and the ADX is above 20, or ideally above 25, then that is a potential signal to buy.
  • It would have been prudent to ignore bearish signals with a bullish continuation pattern taking shape.
  • Below, I will give a few examples of successful strategies with the Alligator and Relative Strength Index but don’t feel limited to use only them.
  • Here are the most common strategies making use of the Average Directional Index.

All three indicators are intertwined and move horizontally. The main oscillator line is below 20-25% and moves horizontally. Due to timeframe restrictions, scalping and swing trading aren’t suitable. At the time of a crossover, the main line is below the 20% level and, after that, the dotted lines start moving upward. Apply the indicator to the chart of the needed currency pair.

Average Directional Index (ADX): Definition and Formula

Wilder put forth a simple system for trading with these directional movement indicators. The first requirement is for ADX to be trading above 25. Wilder based the initial stop on the low of the signal day. The signal remains in force as long as this low holds, even if +DI crosses back below -DI. Wait for this low to be penetrated before abandoning the signal. This bullish signal is reinforced if/when ADX turns up and the trend strengthens.

It shows both the trend’s strength and direction, works well when the price exits a flat, and allows you to differentiate between the beginning of a trend and a local correction. A flat can be identified by the main indicator line that is below 20% and its horizontal movement. Open the trade after the +DI and -DI crossover with the index line exiting the 0-20 zone. Don’t open trades based only on the +DI and -DI crossover strategy. You also need to pay attention to the main indicator line and other signals. If during the crossover, the index line is 30% – 40%, you should ignore the signal.
