These two indicators are often collectively referred to as the Directional Movement Indicator (DMI). The ADX is used to indicate market direction, the existence or nonexistence of a trend and market momentum. Market direction is determined https://traderoom.info/fxopen-overview/ 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.
When it’s sloping upwards, it’s a sign that the uptrend is getting stronger. It’s important to keep in mind that the average directional index is not a trend direction indicator, but an indicator of trend strength. A strong uptrend or a strong downtrend will both result in high average directional index values.

But, as we mentioned above, we check the ADX indicator level as well to ascertain the strength of the trend. Since the value is 100, we will say that the ADX indicator is exhibiting a very strong trend. This can be also visually confirmed by the candlestick plot of the data shown above. We should note that the smoothed version is sort of similar to moving average, as it is used to smoothen out the fluctuations, if any, from the data. This is one of the most useful strategies using the ADX indicator as it signifies a change in dominance. You can simply identify whether bulls are in control or bears are in control and then adjust your position as per the situation.
Whereas, it only means that the trend strength is weakening. As long as ADX is above 25, it should be considered that a falling ADX line is
simply less strong. Whipsaws occur when the indicators criss-cross back and forth, resulting in multiple trade signals that produce losing trades.
How is ADX indicator calculated & ADX indicator Formula
The formula for the average directional movement indicator is complex. But you should at least have a general idea of what it is to read its signals. Many traders in stock market or forex and especially newbies, tend to minimize the stock market and its evolution to a single technical indicator. Besides, do not believe in the Holy Grail and think that the ADX will make you a rich man alone.
When + DI and -DI begin to converge again, this indicates the trend is gradually fading. But we see the data from Jan 2019 onwards, until May 2019, the price rose upwards with the ADX indicator above 25, signifying an uptrend and we can use this as a signal to go long. Here we can see a number of times the Positive Directional Indicator crossed over from under the Negative Directional Indicator.

- Mean Reversion refers to the tendency of a market to revert to its mean after having performed too big moves in either direction.
- When the red line is above the green line, it means a downtrend in price.
- Also note that the stock retraced to 20 day EMA later but it broke through it instead of taking support but that entry is invalid as the ADX is below 20 at that time.
- You can use the Average Directional Index (ADX) indicator if you want to determine the intensity or strength of a trend.
This is due to the fact that at this value, there are lots of strong trends. The negative directional index(DI-) shows the strength of positive price moves. When it’s sloping downwards, it’s a sign the downtrend is getting weaker. The positive directional index(DI+) shows the strength of positive price moves.
Swing Trading Signals
When the +DMI is above the -DMI, prices are moving up, and ADX measures the strength of the uptrend. When the -DMI is above the +DMI, prices are moving down, and ADX measures the strength of the downtrend. The chart above is an example of an uptrend reversing to a downtrend. Notice how ADX rose during the uptrend, when +DMI was above -DMI. When price reversed, the -DMI crossed above the +DMI, and ADX rose again to measure the strength of the downtrend.
ADX should be considered a technical indicator and nothing more, just evaluate the information it provides and include it in our graphical analysis. The “old school” way of using the ADX is to draw a horizontal line on its level 20. As soon as the ADX crosses the level 20, then that usually means that there is a strong trend movement (bullish or bearish). Once this level is reached, it is not rocket science to know in which direction the market is heading, it simply jumps to the eye by observing the stock chart concerned. Crossovers of the directional movement indicators can create trade signals for potential opportunities.
When the ADX has risen above 50, this indicates that the price has picked up momentum in one direction.
