It’s often used as a filter to enhance an existing trading strategy, by removing a lot of unwanted and losing trades. The Average Directional Movement Index (ADX) was developed by famed technical analyst Welles Wilder as an indicator of trend adx meaning in stock market strength. As a commodity trader, Wilder developed the indicator for trading commodity futures. However, it has since been widely applied by technical analysts to virtually every other tradeable investment, from stocks to forex to ETFs.
By contrast, the June 2010 buy signal occurred near a resistance zone marked by broken support and the 50-62% retracement zone. In this instance, it would have been prudent to ignore a buy signal so close to this resistance zone. ADX indicator was introduced by J Welles Wilder and is used to measure the strength of the trend in the https://www.bigshotrading.info/blog/what-is-bull-call-spread/ financial market. This is usually a non-directional indicator which means it does not always show the direction of the trend clearly but merely measures the strength of the same. The ADX indicator is a single-line oscillator that reads between 0 to 100 and rises in case of a strong uptrend and falls in case of a strong downtrend.
How to use the average directional movement index
Even though the differences between this and the previous image aren’t that significant, they are big enough. The formula for calculating ADX may be hard to grasp at first, and is something you could skip if you only want to know how to use the indicator. ADX is calculated by finding the difference between DI+ and DI-, as well as the sum of DI+ and DI-. If the +DI is already above the -DI, when the ADX moves above 25 (or 20, 30) that could trigger a long trade.

Volume-based indicators, basic trend analysis and chart patterns can help distinguish strong crossover signals from weak crossover signals. For example, chartists can focus on +DI buy signals when the bigger trend is up and -DI sell signals when the bigger trend is down. At its most basic, the Average Directional Index (ADX) can be used to determine if a security is trending or not.
What Is Wilder’s DMI (ADX) Indicator?
The key, as always, is to incorporate other aspects of technical analysis. For example, the first group of whipsaws in September 2009 occurred during a consolidation. Moreover, this consolidation looked like a flag, which is a bullish consolidation that forms after an advance. It would have been prudent to ignore bearish signals with a bullish continuation pattern taking shape.
- Traders can therefore exit their trading positions or reduce their position size to avoid potential losses.
- The indicator can also be used as a trend or trade confirmation tool.
- Traders are able to customise trading graphs with our technical analysis indicators and drawing tools, which makes it easier to spot trends and patterns on live price charts.
- Adx indicator on alone does not signify whether the trend is Uptrend or Trend is Downtrend.
- If the +DI is well above -DI, the trend has strength on the upside, and this would help confirm current long trades or new long trade signals based on other entry methods.
A declining ADX value could be an indication of a trend slowing down. But understand that ADX value will go up for trends in both the direction. Above is a spreadsheet example with all the calculations involved. There is a 119-day calculation gap because approximately 150 periods are required to absorb the smoothing techniques.

In order to determine these price trends, traders look to use trend strength indicators, such as the ADX indicator. This technical analysis tool was developed in 1978 by Welles Wilder as a trend strength indicator for the commodities market, although it can be applied to all financial markets. In particular, it is effective when used in collaboration with momentum trading strategies, within the share market and forex trading. This is because strong trends are generally more prominent within highly liquid (and often volatile) markets, so the trader is able to ride the price trend smoothly until it ends. The ADX indicator is one of the most popular and effective trend indicators, especially when used alongside other similar tools.
If DI+ is above DI-, an ADX reading of 25 or higher indicates a strong uptrend. If DI- is above DI+, an ADX reading of 25 or higher indicates a strong downtrend. Several traders believe an ADX value of 25 or higher signifies a strong trend. The point of aggregation or dispersal occurs when ADX falls under 25. For periods of non-trending, oscillators like Stochastic Fast & Slow, RSI, or Williams %R and other range-bound indicators like Bollinger Bands or Moving Average Envelopes could be used.
Why strength matters
The Plus Directional Indicator (+DI) and Minus Directional Indicator (-DI) are derived from smoothed averages of these differences and measure trend direction over time. These two indicators are often collectively referred to as the Directional Movement Indicator (DMI). Positive and negative directional movement form the backbone of the Directional Movement System. Wilder determined directional movement by comparing the difference between two consecutive lows with the difference between their respective highs. There are many ways that you can incorporate indicators and technical analysis into your investing strategy. One way is to use indicators and other chart techniques to supplement your overall assessment of the fundamentals of the global economy, the business cycle, and other factors relevant to your analysis.
Therefore, it is possible that the ADX indicator may generate false signals in markets that are moving sideways or in a range. Traders can hence use the ADX indicator along with other technical indicators to have a better and clear analysis of the market condition. Then the moving average of the directional movement index is calculated. The positive and negative directional indicators need not produce any signal on their own. Instead, the movement and crossover of the lines with the other lines in the indicator produces a signal.
The direction of the ADX line is important for reading trend strength. When the ADX line is rising, trend strength is increasing, and the price moves in the direction of the trend. When the line is falling, trend strength is decreasing, and the price enters a period of retracement or consolidation. ADX reading above 25 indicates trend strength, while when ADX is below 25, this shows trend weakness. Breakouts, which are not difficult to spot, also help to identify whether ADX is strong enough for the price to trend or not. Thus,
when ADX rises from below 25 to above 25, trend is considered strong enough to continue in the direction of the breakout.
- In this section of the guide, we’ll cover some of the most popular and common ADX trading strategies.
- As said above, the crossover of the directional movement indicators could give you a trading signal.
- Although the calculation may look complex, the idea behind the lines is straightforward – the ADX line shows the strength of the current price.
- The ADX indicator is a single-line oscillator that reads between 0 to 100 and rises in case of a strong uptrend and falls in case of a strong downtrend.
- The +DI is only factoring in the current high minus the prior high, when applicable.
