The average directional movement index (ADX) was developed in 1978 by J. ADX’s reading above 25 signals a strong trend, and any reading below 20 signals a weak trend. Whenever the increasing ADX value starts declining, it suggests that the existing trend is coming to an end. If an uptrend is ending, it signals traders to exit the trade, whereas a downtrend ending signals traders to enter new trades.
It would have been prudent to ignore bearish signals with a bullish continuation pattern taking shape. 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 can be used in combination with other technical indicators like moving averages, awesome oscillator, or MACD. For instance, if the index confirms a strong trend while an MACD divergence appears, it can signal that although the trend is strong, a potential reversal or weakening is on the horizon.
These directional movement indicators help to identify trend direction instead of strength, and are not always displayed on price charts. Quite often, the ADX line is plotted as a single line on a graph, with values that range from one to 100. Technical traders have a wide range of tools and indicators at their disposal when making important trading decisions.
- Setting an ADX requirement will reduce signals, but this uber-smoothed indicator tends to filter as many good signals as bad.
- That said, sometimes the ADX reaches above 25, but is only there temporarily and then reverses along with the price.

The Average Directional Index projects market price and it is clearly seen when prices move up (when +DI is above -DI), and when the prices move down (when -DI is above +DI). When there are crosses between both +DI and -DI lines, it can signify potential trading signals, as a bearish or bullish market emerges. The Average Directional Movement Index (ADX) is designed to quantify trend strength by measuring the amount of price movement in a single direction.
This combination stands for the directional movement index technical analysis tool. It’s worth noticing that the ADX indicator is considered a more comprehensive tool when it’s combined with +DI (+DMI) and –DI (-DMI) lines. ADX indicator is never traded alone, but rather in combination with other indicators and tools. The ADX is a non-directional indicator, meaning https://traderoom.info/adx-trend-indicator/ it does not provide information about the direction of the trend.
The five best combinations where ADX works the best are price action, RSI, MACD, Moving Averages, Stochastics, and Pivot Points. ADX measures trend strength, while price action analysis determines trend direction and reversal points. Candlestick patterns, support/resistance, pivots, etc. integrated with ADX and price action confirms the actual buy and sell signals. ADX is non-directional, so price action complements it perfectly. Technical analysis is a trading discipline that involves researching and analyzing past market data to make predictions about future performance. These individuals look for entry and exit points in the market using historical prices and trading volume.
- They help traders determine overbought or oversold conditions in the market.
- The Directional Movement System indicator calculations are complex, interpretation is straightforward, and successful implementation takes practice.
- Until the indicator fell below 20, a trader could believe the trend was in strength.
- Charts, graphs, and other tools are important to technical analysis.

Trend Strength
In a market that is heading substantially upward, ADX values will grow to increasingly high levels. However, if ADX levels begin to fall even as prices climb, this divergence between price movement and the ADX may indicate that the market is losing momentum and is thus due for a shift to the negative. As we learned above, the market may show weak signals when the ADX line falls. As mentioned above, the ADX indicator is rarely used by traders to indicate the trend direction. Traders are most likely to use ADX with moving averages or support/resistance.
Traders can use the ADX to determine whether a market is trending or ranging, as well as to identify potential entry and exit points. The Average Directional Index (ADX) is a popular technical indicator used by traders to identify the strength of a trend. In this tutorial, we will explore the ADX indicator in detail and learn how to use it in Python for trading purposes. Conversely, values under 20 often signify a market that is either weakly trending or largely range-bound, where traditional trend-following tactics may yield inconsistent results.
The ADX is best used as a filtering mechanism to determine trend strength. For trade entry and exit signals as well as trend direction, it must be combined with price action analysis and other complementary indicators. Used on its own, the ADX has limitations that sometimes lead to poor quality signals. Using an ADX strategy to assess the performance of stocks allows traders to see when a particular share is overbought or oversold, according to the succession of lowering peaks.
Investors should first use ADX to determine whether prices are trending or non-trending and then choose the appropriate trading strategy for the condition. The ADX identifies a strong trend when the ADX is over 25 and a weak trend when the ADX is below 20. Crossovers of the -DI and +DI lines can be used to generate trade signals. 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.
Limitations of the Average Directional Index
But a close above the 200 MA when ADX is below 20 indicates limited trend support for this “breakout” – the chance of falling back below the MA is higher. ADX also confirms MA crossover signals are supported by real trend momentum before acting on them. The ADX works best when combined with other technical indicators, like the relative strength index (RSI). While the ADX measures the intensity of the trend, the RSI can help with entries and exits by giving a time-based component to the trend. Yes, but it provides better strategy signals when combined with price.
Understanding the Average Directional Index (ADX)
Strong trends tend to continue, making the ADX useful in finding opportunities to trade against it and when trends slow or reverse unexpectedly. Conversely, it also warns traders whenever those trends become less dominant and are possibly ready to change direction suddenly. Early detection and identification are essential components to ensure trading success and the ADX offers valuable analysis of trend quality and potential inflection points. The Average Directional Index should be combined with other indicators that examine price and others that can help filter signals and control risk to get the most out of the tool. Like most indicators, it works best when paired with highly functioning data processors and other analytical tools.
How To Calculate Average Directional Index
It helps traders identify if the market is trending or if it’s in a consolidation phase. The ADX is part of the Directional Movement System, which also includes the positive directional indicator (+DI) and negative directional indicator (-DI). The index value ranges from 0 to 100, with readings above 25 typically indicating a strong trend and readings below 25 suggesting weak or non-existent trends.
