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