Directional Movement Quality Index

Indicator DMX (Bipolar DMI) is calculated using the standard indicator ADX. However, as compared to that, it displays data as an oscillator with a signal line, and has shorter delay.

DMX = (P-M) / (P+M)
Signal = MA(DMX, Signal period, Method)

where:

P - (+DI) ADX indicator line;
M - (-DI) ADX indicator line.
