Average Directional Index


Function Name: adx

Tags: None

Category: Trend

The Average Directional Index (ADX) measures the strength of a prevailing trend as well as whether or not there is movement or direction in a market.

A rising ADX indicates a strong trend. If the ADX is over 40 and begins to fall, it can signal a slowdown of a current trend.

A falling ADX suggests a non-trending market. A low ADX value (generally less than 20) can indicate a non-trending market with low volatility whereas a cross above 20 may signal the start of a trend (either up or down).

The ADX does not, however, indicate whether a trend is up or down. This indicator can be used to identify non-trending markets, or a deterioration of an ongoing trend. Although market direction is important in its calculation, the ADX is not a directional indicator.
