# %B

The %B indicator is based on the position of price relative to the Bollinger Bands.

It is calculated as follows:

```
%B = (Price - Lower Band) / (Upper Band - Lower Band)
```

Example values and positions relative to Bollinger Bands:

* **%B = 1**: The price is exactly at the upper band.
* **%B = 0**: The price is exactly at the lower band.
* **%B = 0.5**: The price is at the midpoint between the bands (the moving average).
* **%B > 1**: The price is above the upper band.
* **%B < 0**: The price is below the lower band.
