The Directional Movement Oscillator (DMO) is an adaption to the Directional Movement Index (DMI).
The difference is that DMO is one line, whereas DMI has 3 lines: +DI,-DI, and ADX.
The DMO line calculation: DMO = (+DI) - (-DI)
I excluded the ADX in DMO because its completely useless.
Try this indicator out, good luck ;)
