# forge.ta.Keltner

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

An EMA with bands set by the average true range.

middle = the EMA of the closes over ema_period

upper = middle + atr_factor * ATR, lower = middle - atr_factor * ATR

ATR is the simple average of the true range over atr_period, as the MetaTrader 5 Keltner Channel computes it.
