# forge.ta.tr

```python
forge.ta.tr(high: ArrayLike, low: ArrayLike, close: ArrayLike) -> np.ndarray
```

True range: the bar's range widened to take in the gap from the previous close.

The first bar has no previous close and no value. NaN on a bar where one of the values it
reads is missing, and on the bar after a missing close.

Since Forge API 1.
