ADX Indicator in Trading: Strategy & Calculation


Average Directional Index

As an oscillator,RSIdelivers overbought and oversold trading signals. An RSI reading of above 70 implies overbought conditions, whereas a reading of below 30 implies oversold conditions. A buy order in a ranging market will be when the price is drifting lower, with an ADX reading of below 25, and when the RSI is showing oversold conditions. Similarly, a sell order can be placed when the price is edging higher, with an ADX reading of below 25 and when the RSI is showing overbought conditions. 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.

  • It is important to ensure that you do not combine the wrong indicators, which can lead to indicator redundancy and overemphasising information.
  • This bullish signal is reinforced if/when ADX turns up and the trend strengthens.
  • This indicator’s definition is further expressed in the condensed code given in the calculation below.
  • One of the best buy signals is when ADX turns up when below both Directional Lines and +DI is above -DI.
  • When the price creates a higher high, but the index doesn’t follow it and instead forms a lower high, this is divergence.
  • Similarly, a signal to sell will be triggered when the MACD falls below the zero line, with the ADX rising above 20 and the -DI line crossing above the +DI line.

As mentioned earlier, the ADX is commonly used within highly liquid markets. Arguably the most liquid financial market — forex trading. The ADX indicator, when applied to currency trading, helps measure a currency pair’s strength to see whether the instrument will increase or decrease in price. Using this method will reflect its trend momentum and indicate the presence of either an upward or downward trend. Using the ADX indicator can provide us with information that is missing from a basic price chart. Although Wilder designed his Directional Movement System with commodities and daily prices in mind, these indicators can also be applied to stocks. The Average Directional Index is a very useful tool for trend traders.

The DI lines

The buy/sell signals indicate the opening of a confluence in either direction, whereas the candle coloring shows when that confluence ends. Like the ADX, crossovers of the two Aroon lines can signal trend changes. Still, as the calculations of each indicator are different, crossovers on each indicator will happen at different periods. Applying an ADX strategy to evaluate the performance of shares allows traders to see when one is overbought or oversold, according to the sequence of lowering peaks. Directional movement indicator crossovers can be used to estimate the performance of a security and predict coming changes in a trend, such as reversals or breakouts.

One way to trade using ADX is to wait for breakouts first before deciding to go long or short. EUR/CHF broke below the bottom of the range and went on a strong downtrend. When you’re using the ADX indicator, keep an eye on the 20 and 40 as key levels. When the ADX has risen above 50, this indicates that the price has picked up momentum in one direction. Determine significant support and resistance levels with the help of pivot points.

The ADX indicator is one of the most popular and effective trend indicators, especially when used alongside other similar tools. It is common investing wisdom that detecting and trading in the direction of a strong trend is a profitable strategy with minimal risk exposure.

  • Our ADX trading system is also available to access through a demo account, where you can practise first with virtual funds.
  • For this reason, the ADX indicator and other trend-based indicators do not work as well for the share market as for other financial instruments.
  • Wilder suggests that a strong trend is present when ADX is above 25 and no trend is present when ADX is below 20.

  • Technical analysis focuses on market action — specifically, volume and price.

This scan starts with stocks that average 100,000 shares daily volume and have an average closing price above 10. A downtrend is present when trading below the 50-day SMA. 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. On the other hand, if the -DI crosses above the +DI, and the ADX is above 20 or 25, then that is an opportunity to enter a potential short trade.

The ADX indicator is a momentum indicator that is used along with the negative directional indicator (-DI) and positive directional indicator (+DI). 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. 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 markets, so the trader is able to ride the price trend smoothly until it ends.

Which is the best indicator for swing trading?

Momentum indicators highlight potential oscillations within a broader trend, making them popular among swing traders. Perhaps the most widely used example is the relative strength index (RSI), which shows whether a market is overbought or oversold – and therefore whether a swing might be on the horizon.

On the other hand, when ADX is below 25, many will avoid trend-trading strategies. As we have mentioned earlier in the article, the ADX indicator is often used within highly liquid markets, and forex trading​​ is arguably the most liquid financial market of them all. When applied to currency trading, the ADX indicator helps to measure the strength of a currency pair, to see whether the asset is increasing or decreasing in price. This will reflect its trend momentum and predict when the trend is starting to fade.

To make the most of its potential, the advice is to use the tool when the market is trending in either direction. To apply an ADX oscillator to a chart, a trader needs to follow the procedure common to all Marketscope indicators. Newbies think that when the indicator drops, it means the trend is reversing. In fact, it only indicates that the trend is weakening. Until the indicator crosses 25, think of the trend as being weaker.

This article will highlight the Average Directional Index , which is an important indicator that is used to measure trend strength. It doesn’t incorporate all of the data necessary for a thorough price action analysis, so it’s advised to use it in combination with other indicators.

Directional movement is negative when the prior low minus the current low is greater than the current high minus the prior high. This so-called Minus Directional Movement (-DM) equals the prior low minus the current low, provided it is positive. Directional movement is positive when the current high minus the prior high is greater than the prior low minus the current low. This so-called Plus Directional Movement (+DM) then equals the current high minus the prior high, provided it is positive.
