ADX has some weaknesses that make it unsuitable to be used as a standalone indicator. To start with, it is based on moving Average Directional Index averages, which means that it is largely a lagging indicator that reacts slower to price changes in the market.

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. Directional movement is calculated by comparing the difference between two consecutive lows with the difference between their respective highs.

As a provider of educational courses, we do not have access to the personal trading accounts or brokerage statements of our customers. As a result, we have no reason to believe our customers perform better or worse than traders as a whole. The ADX is not a useful indicator when prices are moving sideways. An ADX line may drop below 20 and even get closer to 10 during a prolonged consolidation period.

Breakouts happen when an asset’s price has sudden momentum, generally due to increased supply and demand. The difference creates price momentum, whether it is more demand than supply or more supply than demand. Generally, ADX peaks above 25 are considered solid, even if they are lower. In an uptrend, the price can still rise on a falling ADX momentum because overhead supply is used up as the trend https://www.bigshotrading.info/ progresses.

The ADX considers every possible configuration that could occur between two days of trading relative to the Directional Movement Index. The largest part of today’s high or low that is outside of yesterday’s high or low range is calculated. If the largest part of today’s range is above yesterday’s, then the value is marked as PDI, while the largest part of today’s range below yesterday’s yields a value denoted as MDI. The Directional Movement is divided by the True Range in order to make directional movement relative to true range. 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. ADX crossovers can take time to form in the market, and traders can enter a trending market early with Parabolic SAR when 3 consecutive parabolas are printed in the direction of the trend. Similarly, an early exit signal can be identified by Parabolic SAR when the parabolas flip onto the opposite side of the trend.
