ADX Indicator Average Directional Index ADX Indicator Formula

The ADX is used to indicate market direction, the existence or nonexistence of a trend and market momentum. Market direction is determined by the levels of the +DI and -DI. If +DI is the higher number, market direction is up; if -DI is the greater number, market direction is down. The ADX indicator, which varies in value from zero to 100, is the primary momentum indicator.

The default setting is 14 bars, although other time periods can be used. The average directional index, or ADX, is the primary technical indicator among the five indicators that make up a technical trading system developed by J. Welles Wilder, Jr. and is calculated using the other indicators that make up the trading system. The ADX is primarily used as an indicator of momentum, or trend strength, but the total ADX system is also used as a directional indicator.

There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. ADX is simply the mean, or average, of the values of the DX over the specified Period. Values may vary slightly depending on the data accuracy and number of candles tested. Google recently stopped providing API access to the live data. We are looking for alternate free methods to update this sheet.

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.

Now, in this https://traderoom.info/, ADX will act as a filter for another entry condition to improve its accuracy and ensure that we have the odds in our favor. Mean ReversionAs is visible above, we say that a market is oversold once it has moved too much to the downside, and overbought when it has gone up too much. Trending ADXEven though the differences between this and the previous image aren’t that significant, they are big enough. If the red line(-DI) is higher than the green line(+DI) that is generally an indication of a bearish trend. Conversely, if the green line(+DI) is higher than the red line(-DI) that is generally an indication of a bullish trend.

Similarly, when the –adx indicator formula crosses above the +DI line, it implies that the rate of negative price change in the market is greater than the positive price change. If this happens when the ADX is below 25, it is a solid signal to place sell orders. Crossovers are as much a trigger of trade entry as they are for trade management and exits.

Unlike other trend indicators the ADX is non-directional, meaning it simply register the strength of the trend, not whether it is an up-trend or a down-trend. In order to indicate whether prices are moving higher or lower the ADX Indicator is plotted with the +DMI and –DMI lines from which the ADX is derived. Parabolic SAR is a leading trend following indicator, and when combined with ADX, it could help traders to capture maximum returns in a trending market. Similarly, an early exit signal can be identified by Parabolic SAR when the parabolas flip onto the opposite side of the trend. This can be used instead of waiting for the +DI and -DI crossovers.

Adjusting the Threshold Values

The average directional movement index was developed in 1978 by J. Welles Wilder as an indicator of trend strength in a series of prices of a financial instrument. ADX has become a widely used indicator for technical analysts, and is provided as a standard in collections of indicators offered by various trading platforms. The chart above shows Medco Health Solutions with the three directional movement indicators. Note that 20 is used instead of 25 to qualify ADX signals.

• Since the value is 100, we will say that the ADX indicator is exhibiting a very strong trend.
• That way we adopt an adaptive approach that takes into account the recent performance of the market.
• The slope of the ADX line is proportional to the acceleration of the price movement .
• The ADX at the top uses has a length of 5, the middle a length of 10, and the one at the bottom a length of 20.

In general, ADX is used in conjunction with +DI and -DI indicators which also helps in determining the direction of trend. If +DI value is greater than -DI then it indicates bullishness, and if +DI value is less than -DI then it indicates bearishness. Crossovers of DI lines can further help in timing the trades. Contraction periods are also marked when the +DI and -DI lines become squished together.

Alternative interpretations have also been proposed and accepted among technical analysts. For example it has been shown how ADX is a reliable coincident indicator of classical chart pattern development, whereby ADX readings below 20 occur just prior to pattern breakouts. The value of the ADX is proportional to the slope of the trend. The slope of the ADX line is proportional to the acceleration of the price movement . If the trend is a constant slope then the ADX value tends to flatten out.

There is a downloadable Excel sheet at the end of the post where you can download real time stock quotes with ADX values. Irrespective of whether the trader takes a long or short position, the ADX should be over 25 when the crossover occurs to confirm the trend’s strength. When the ADX is below 20, traders could use trading strategies that exploit range bound or choppier conditions. This scan starts with stocks that average 100,000 shares daily volume and have an average closing price above 10.

Welles Wilder Jr. introduced the directional movement index, or DMI, in 1978. Wilder wanted an indicator that could measure the strength and direction of a price movement so traders could avoid false signals. The DMI is actually two different standard indicators, one negative and one positive, that are plotted as lines on the same chart. A third line, the average directional index, or ADX, is nondirectional but shows movement strength. The ADX, negative directional indicator (-DI), and positive directional indicator (+DI) are momentum indicators. The ADX helps investors determine trend strength, while -DI and +DI help determine trend direction.

ADX Indicator Trading Strategy

The calculations are different though, so crossovers on each of the indicators will occur at different times. Remember that we said the ADX Indicator tells us the strength of the trend and not the direction. To give a brief recap of the situation, so far we found out the positive directional indicator and the negative directional indicator. Analysts and investors rarely use the average directional index indicator alone.

While ADX can be plotted above, below or behind the main price plot, it is recommended to plot above or below because there are three lines involved. A horizontal line can be added to help identify ADX moves. The chart example below also shows the 50-day SMA and Parabolic SAR plotted behind the price plot. Only buy signals are used when trading above the 50-day moving average. Once initiated, the Parabolic SAR can be used to set stops.

A value over 20 indicates the existence of a trend; a value over 40 indicates a strong trend. The first technique is used to smooth each period’s +DM1, -DM1 and TR1 values over 14 periods. As with an exponential moving average, the calculation has to start somewhere so the first value is simply the sum of the first 14 periods. As shown below, smoothing starts with the second 14-period calculation and continues throughout.

• Before looking at some signals with examples, keep in mind that Wilder was a commodity and currency trader.
• ADX measures the strength of the trend, either up or down; a reading above 25 indicates a strong trend.
• Cory is an expert on stock, forex and futures price action trading strategies.
• By contrast, the June 2010 buy signal occurred near a resistance zone marked by broken support and the 50-62% retracement zone.
• The ability to quantify trend strength is a major edge for traders.

The traditional setting for the ADX indicator is 14 time periods, but analysts have commonly used the ADX with settings as low as 7 or as high as 30. Lower settings will make the average directional index respond more quickly to price movement but tend to generate more false signals. Higher settings will minimize false signals but make the average directional index a more lagging indicator.

Breakouts are not hard to spot, but they often fail to progress or end up being a trap. However, ADX tells you when breakouts are valid by showing when ADX is strong enough for price to trend after the breakout. When ADX rises from below 25 to above 25, price is strong enough to continue in the direction of the breakout.

Conversely, it is often hard to see when price moves from trend to range conditions. ADX shows when the trend has weakened and is entering a period of range consolidation. Range conditions exist when ADX drops from above 25 to below 25. In a range, the trend is sideways, and there is general price agreement between the buyers and sellers. ADX will meander sideways under 25 until the balance of supply and demand changes again.
