It is also important to consider the length of the period used to calculate the ADX and to choose a period that is appropriate for the type of market and instrument being traded. The minus DMI is typically plotted separately on a chart and can be used to identify downward trends in a market. Although being familiar with the formula can come in handy, measuring ADX calculations yourself is unnecessary, as most https://www.bigshotrading.info/ online trading systems will automatically calculate technical indicators. ADX calculations are based on a moving average of a price range expansion over a specific time period to quantify trend strength. The default setting recommended by Wilder is 14 bars, although other timeframes can be implemented. This strategy is useful mainly to cut the false signals potentially generated by the ADX to a minimum.
This average is then smoothed using a moving average to create the ADX line. The smoothing period for the ADX line is typically set at 14 periods, although this can be adjusted based on the needs of the trader or investor. First, the difference between the current low price and the previous low price is calculated. If this difference is negative, it is added to the previous minus DMI value.
Using the ADX in Conjunction with Other Technical Indicators
It’s important to understand the effects of all the smoothing involved in the ADX, +DI and -DI calculations. Because of Wilder’s smoothing techniques, it can take around 150 periods of data to get true ADX values. Wilder uses similar smoothing techniques with his RSI and Average True Range calculations. ADX values using only 30 periods of historical data will not match ADX values using 150 periods of historical data. ADX values with 150 days or more of data will remain consistent.
- The stronger the trend, the larger the reading regardless of whether it is an uptrend or downtrend.
The Adaptive Fusion ADX DI Vortex Indicator is a powerful tool designed to help traders identify trend strength and potential trend reversals in the market.
- With that said, ADX can be used to supplement your view of short-term trends.

To make the most of it, make sure to apply it cautiously and double-check its signals on multiple time frames. When we trade in the direction of a strong trend, it reduces risk and also increases our profit potential. ADX fluctuates from 0 to 100, with readings below 20 indicating a weak trend and readings above 50 signaling a strong trend. Commodity and historical index data provided by Pinnacle Data Corporation.

Learn how it compares to active investing and why it’s a preferred choice for many modern investors seeking steady growth. Traders should be wary of crossovers, which can occur quite frequently and result in losses if not evaluated with other factors. False signals are more common with ADX values below 25, but reversals can also happen above that threshold. The ADX indicator equals 100 times the EMA of the absolute value of (+DI minus -DI) divided by (+DI plus -DI).
The chart above shows Nordstrom (JWN) with the 50-day SMA and 14-day Average Directional Index (ADX). The stock moved from a strong uptrend to a strong downtrend in April-May, but ADX remained above 20 because the strong uptrend quickly changed into a strong downtrend. There were two non-trending periods as the stock formed a bottom in February and August. A strong trend emerged after the August bottom as ADX moved above 20 and remained above 20. At its most basic, the Average Directional Index (ADX) can be used to determine if a security is trending or not.
TRADING & INVESTING WITH ADX (AVERAGE DIRECTIONAL MOVEMENT INDEX)
These three signals were pretty good, provided profits were taken and trailing stops were used. Wilder’s Parabolic SAR could have been used to set a trailing stop-loss. Notice that there was no sell signal between the March and July buy signals. This is because ADX was not above 20 when -DI crossed above +DI in late April. Looking at a chart of the S&P 500 might give you some cause for optimism. While stocks are down 11% year to date on a total return basis, they are up roughly 9% since reaching bear market territory in early June.
The Average Directional Index (ADX) is used to measure the strength or weakness of a trend, not the actual direction. In general, the bulls have the edge when +DI is greater than -DI, while the bears have the edge when -DI is greater. Crosses of these directional indicators can be combined with ADX for a complete trading system. 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.

This article delves into the use of the Average Directional Index (ADX) in trading and further expands on margin trading. The ADX is a lagging indicator, meaning a trend must have established itself for the ADX to generate a signal that a trend is underway. Moreover, the ADX indicator alone won’t supply enough data to be used on its own and can provide false signals when used on shorter periods. The ADX is a lagging indicator, meaning a trend must have established itself for the indicator to generate a signal that a trend is underway.

Common Mistakes When Using the ADX
If the up-move is greater than the down-move and greater than zero, the +DM equals the up-move; otherwise, it equals zero. If the down-move is greater than the up-move and greater than zero, the -DM equals the down-move; otherwise, it equals zero. The Average Directional Index (ADX) is in turn derived from the smoothed averages of the difference between +DI and -DI; it measures the strength of the trend (regardless of direction) over time. The Directional Movement Index (DMI) assists in determining if a security is trending and attempts to measure the strength of the trend. It only attempts to determine if there is a trend and that trends strength.
