Jurik Directional Movement Index (DMX)

Category: trend, momentum

A sophisticated version of the Directional Movement Index that utilizes Jurik-style adaptive smoothing to reduce lag while maintaining smoothness. It compares positive and negative movement normalized by their sum, processed through a low-lag adaptive filter.

Formula

\text{DMX} = \text{JMA}(\frac{DI^+ - DI^-}{DI^+ + DI^-}, \text{period}) \\ \text{where } DI \text{ is Wilder's smoothed DM and JMA is a volatility-adaptive moving average.}

Inputs

• i_period (default: 14)
