# forge.ta.ac

```python
forge.ta.ac(high: ArrayLike, low: ArrayLike, fast_period: int = 5, slow_period: int = 34, signal_period: int = 5) -> np.ndarray
```

Accelerator oscillator: the Awesome oscillator minus its own ``signal_period`` average.

NaN for the first ``slow_period + signal_period - 2`` bars.

Since Forge API 1.

## Class forge.ta.AC

```python
forge.ta.AC(**inputs: Any) -> None
```

How fast the Awesome oscillator is speeding up or slowing down.

AC = AO - SMA(AO, signal_period)

Since Forge API 1.
