What is bb-buy-sell-zone-indicator?

It displays real-time metrics in an information panel, including the relative percentage position of price within the band range.
How to use bb-buy-sell-zone-indicator
Read Upper BB, Middle BB, Lower BB, and Range P % together to locate price within the Bollinger Band:
- Compare Range P % with the upper, middle, and lower band positions displayed on the chart.
- Use the colored regions to distinguish where price is located within the band rather than as buy-or-sell labels.
- Adjust BandsPeriod, Deviations, BandsShift, fill, and label options to change the band display.
- Compare the location value with band width and the recent chart movement, since price can remain near an outer region.
