# forge.ta.heikin_ashi

```python
forge.ta.heikin_ashi(open: ArrayLike, high: ArrayLike, low: ArrayLike, close: ArrayLike, seed: str = 'mt5_raw') -> dict[str, np.ndarray]
```

Heikin-Ashi candles: ``ha_open``, ``ha_high``, ``ha_low`` and ``ha_close``.

``seed="mt5_raw"`` starts from the raw first bar (``ha_open = open``, ``ha_close = close``, the
way MetaTrader 5 does). ``seed="textbook"`` starts from ``ha_close = (o + h + l + c) / 4`` and
``ha_open = (open + close) / 2``. No warm-up: a value exists on every bar that has all four
prices.
