```python
forge.ta.dark_cloud_cover(open: ArrayLike, high: ArrayLike, low: ArrayLike, close: ArrayLike, long_body_pct: float = 50.0, penetration: float = 0.5) -> np.ndarray
```

Dark cloud cover: a fall that closes deep into the previous rise. Found: -1.

The first bar rises with a long body, the second opens at or above its close and closes at least
``penetration`` of the first body below that close, still above the first open.
