Average Directional Movement Index (ADX)
The ADX is a Welles Wilder style moving average of the Directional Movement Index (DX). The values range from 0 to 100, but rarely get above 60. To interpret the ADX, consider a high number to be a strong trend, and a low number, a weak trend.
See also +/-DI, DX and ADXR.
The ADX was developed by J. Welles Wilder and is described in his 1978 book New Concepts In Technical Trading Systems.
