The ADX Indicator and How to Use It in Systematic Trading

The traditional interpretation is that high ADX readings ensure that it’s likely for the market to continue in the direction of the prevailing trend. This is the line that you will use to determine the trend strength, and its reading is not affected by the direction of the trend. As you see, the ADX line goes back and forth, as the trend strength of the market changes. One of the most important things to remember about ADX trading is that the indicator moves regardless of the direction of the underlying asset, showing only the strength of the trend.

What is a good average directional index?

  1. The Plus Direction Indicator (DI+) and Minus Direction Indicator (DI-) show the current price direction.
  2. As long as ADX is above 25, think of a falling ADX line as reflecting a trend that is simply less strong (shown below).
  3. In layman’s terms, a series of higher ADX peaks means trend momentum is increasing, whereas a series of lower ADX peaks means trend momentum is decreasing.
  4. Alternatively, when the -DI crosses past the +DI line, and the ADX reading is above 20, then they may see this as an excellent opportunity to sell and go short (bear market DI crossover).
  5. While many other technical indicators that try to do much more are far more popular, the Average Directional Index has but one job – to denote trend strength.

One thing to keep in mind, though, is that the ADX is a lagging indicator.

It is a component of the Directional Movement System, a larger set of technical indicators. In layman’s terms, a series of higher ADX peaks means trend momentum is increasing, whereas a series of lower ADX peaks means trend momentum is decreasing.

It may be appropriate to tighten the stop-loss or take partial profits. Using the ADX indicator can provide us with information that is missing from a basic price chart. For example, the ADX helps determine support and resistance levels, which show whether a price is staying within its trend range or significant price fluctuations that may lead to a breakout. The sequence of ADX peaks is a visual indication of overall trend momentum, demonstrating when the trend is gaining or losing momentum – the acceleration of price. A succession of higher ADX peaks indicates trend momentum is rising. At the same time, a series of lower ADX peaks shows decreasing momentum.

This can happen when there are multiple crossovers, which can make it complicated to discern the best entry or exit points as trends make quick changes in direction. The ADX is also a lagging indicator, which means it moves behind prices. As such, it doesn’t necessarily provide accurate entry or exit signals.

Technical traders have a wide range of tools and indicators at their disposal when making important trading decisions. The average directional index helps them determine the strength of market trends as well as their direction.

However, in the end, it is the chartist’s ability to quantify trend strength and stay one step ahead that matters. Thus, ADX should be used in tandem with other technical indicators and chart patterns to generate better trading signals. The positive directional indicator is 100 times the exponential moving average (EMA) of +DI divided by the average true range (ATR) for a set number of periods (typically 14 days). In summary, the Average Directional Index (ADX) is a powerful and widely used technical indicator for determining the strength and direction of a trend in financial markets.
