The ADX reading is an average of the absolute difference between these two values, which is the reason why it only shows the strength of the trend, and not its direction. In the image below, a high ADX reading is highlighted with a circle. Notice how the ADX reading went up together with the increase in market trend strength, coming from a low volatility environment. This line shows trend strength by taking a smoothed average of the difference between +DI and -DI. Thus, when +DI crosses above -DI it signals the potential for a new price uptrend.

Is ADX a Good Indicator?
The ideal scenario is that the ADX is rising, but I don’t find it necessary to take a trade. Now look at what happens when the indicator gets into higher territory. The ADX indicator is made up of three lines namely the ADX line, the Positive Directional Indicator (+DI) line, and the Negative Directional Indicator (-DI) line. The ADX line is the primary line, and it shows the strength of the trend. On the other hand, the other lines, +DI and -DI, show the direction of the trend. The +DI and -DI lines can be used to determine the direction of the trend.
- A couple of weeks later, the ADX quickly drops below 25—which marks the end of the stock’s upward trend.
- Once ADX gets above 25 then you will begin to see the beginning of a trend.

SharpCharts users can plot these three directional movement indicators by selecting Average Directional Index (ADX) from the indicator dropdown list. By default, the ADX line will be in black, the Plus Directional Indicator (+DI) in green and the Minus Directional Indicator (-DI) in red. While ADX can be plotted above, below or behind the main price plot, it is recommended to https://www.bigshotrading.info/ plot above or below because there are three lines involved. 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. The two indicators are similar in that they both have lines representing positive and negative movement, which helps to identify trend direction.
What is the meaning of ADX indicator?
The green dotted lines show the buy signals and the red dotted lines show the sell signals. Wilder’s initial stops were not incorporated adx meaning in stock market in order to focus on the indicator signals. As the chart clearly shows, there are plenty of +DI and -DI crosses.
- Therefore, it is possible that the ADX indicator may generate false signals in markets that are moving sideways or in a range.

The ADX indicator is determined as an average of expanding price range values. The ADX Indicator is a component of the Directional Movement System developed by Welles Wilder. 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.
The negative directional indicator, or -DI, equals 100 times the exponential moving average of -DM divided by the average true range (ATR). The ADX indicator itself equals 100 times the exponential moving average of the absolute value of (+DI minus -DI) divided by (+DI plus -DI). The average directional movement index (ADX) is used by technical traders to determine trend strength as well as trend direction. Using the ADX, traders can determine if a market is trading or ranging, and then apply the adequate technical trading strategy.

When the negative DI moves upwards then there will be a downtrend in the market. When the negative DI moves downwards then there will be an uptrend in the market.
