The ADX is a Welles Wilder style moving average of the Directional Movement Index (DX). The values range from 0 to 100, but rarely get above 60. To interpret the ADX, consider a high number to be a strong trend, and a low number, a weak trend.

### Usage

```python
adx [-l N_LENGTH] [-s N_SCALAR] [-d N_DRIFT]
```
