Average Directional Index

The Average Directional Index is a technical analysis indicator used to quantify the strength of a price trend, regardless of its direction. It is derived from the moving average of price range expansion over a specified period, typically 14 days.

The indicator oscillates between 0 and 100, where higher values indicate a stronger trend and lower values suggest a weak trend or a ranging market. It does not provide buy or sell signals itself but helps traders determine if a market is trending or consolidating.

In cryptocurrency markets, high ADX readings often precede significant breakouts or breakdowns. It is composed of two other indicators, the Positive Directional Indicator and the Negative Directional Indicator, which help identify the trend's direction.

Traders often use it to filter out choppy, non-trending markets where trend-following strategies might fail. When the ADX is rising, the current trend is strengthening, while a falling ADX suggests the trend is losing momentum.

It is a lagging indicator, meaning it reflects past price action rather than predicting future moves. By understanding ADX, traders can better align their strategies with the prevailing market environment.
