Directional Movement using Hann (DMH)

The Directional Movement using Hann (DMH) is a modernized, smoothed version of J. Welles Wilder's classic Directional Movement Index (DMI). Introduced by renowned quantitative analyst John Ehlers in 2021, the DMH uses a Hann windowing function to reduce lag and smooth out the erratic signals common in the original indicator.
