```
usage: wma [-l N_LENGTH] [-o N_OFFSET] [--export {csv,json,xlsx}] [-h]
```

A Weighted Moving Average puts more weight on recent data and less on past data. This is done by multiplying each bar’s price by a weighting factor.
Because of its unique calculation, WMA will follow prices more closely than a corresponding Simple Moving Average.
