The Average Directional Index (ADX) is a technical indicator that helps measure the strength of a trend in a financial market. It was developed by J. Welles Wilder and is used to assess the strength of both upward and downward trends.

The ADX is calculated using a formula that involves smoothing a series of directional movement values over a specified period. The value ranges from 0 to 100, with higher values indicating a stronger trend. A value below 20 is usually seen as a weak trend, while a value above 40 is typically considered a strong trend.

Traders and investors use the ADX to determine whether a market is trending or range-bound. It also helps in identifying potential trend reversals. When the ADX is trending upwards, it suggests an increasing strength of the trend, while a declining ADX indicates a weakening trend.

Additionally, the ADX is often used in conjunction with other technical indicators, such as the Positive Directional Index (+DI) and Negative Directional Index (-DI), to generate trading signals and confirm trend strength or weakness.

Overall, the Average Directional Index is a widely used technical tool for evaluating the strength and direction of market trends.
