# forge.ta.wilder

```python
forge.ta.wilder(source: ArrayLike, period: int = 13) -> np.ndarray
```

Wilder's smoothed average: seeded with the mean of the first ``period`` values.

Then ``(previous * (period - 1) + price) / period``. After a gap it restarts with a new seed.
Also known as ``smma`` and ``wilder``.

Since Forge API 1.
