# forge.ta.aroon

```python
forge.ta.aroon(high: ArrayLike, low: ArrayLike, period: int = 14) -> dict[str, np.ndarray]
```

Aroon: how recently the highest high and the lowest low of the last ``period + 1`` bars came.

100 when it is the current bar, 0 when it is ``period`` bars back. A tie goes to the newest
bar. ``osc`` is ``up - down``.

Since Forge API 1.
