It aims to facilitate the grouping of this category of indicators, and also offer the customized supply of

Indicators (this is a work in progress):

1. Absolute DI (Directional Moviment Index) (Difference between DI+ and DI-).
Used in 'DMI Stochastic Extreme' by Barbara Star.
2. DMI

DI_Abs(lengthDI, smoothDI, typeMA, lengthMA)
  @description Absolute DI (Directional Moviment Index).
Used in 'DMI Stochastic Extreme' by Barbara Star.
Difference between DI+ and DI-
  Parameters:
    lengthDI: (int) Length of DI+/DI-
    smoothDI: (bool) Sets whether absolute DI should be smoothed
    typeMA: (int) Type of moving average of smoothing
    lengthMA: (int) Length for moving average of smoothing
  Returns: (float) Absolute value of DI

dmi(diLength, adxSmoothing)
  @description DMI (Directional Movement Index)
Same as ta.dmi()
  Parameters:
    diLength: (int) Length of DI+/DI-
    adxSmoothing: (int) ADX Smoothing
  Returns: Tuple of three DMI series: Positive Directional
Movement (+DI), Negative Directional Movement (-DI) and Average Directional Movement Index (ADX).

dmi(source, diLength, adxSmoothing)
  @description DMI (Directional Movement Index)
Customized version of ta.dmi(), with custom source
  Parameters:
    source: (float) Source for DI+/DI-
    diLength: (int) Length of DI+/DI-
    adxSmoothing: (int) ADX Smoothing
  Returns: Tuple of three DMI series: Positive Directional
Movement (+DI), Negative Directional Movement (-DI) and Average Directional Movement Index (ADX).
