Bollinger Bands Width and Bollinger Bands %B

2022년 10월 6일

This script shows both the Bollinger Band Width(BBW) and %B on the same indicator window.
Both the BBW and %B are introduced by John Bollinger(creator of Bollinger Bands) in 2010.


Default Parameter values: Length = 20, Source = Close, Mult = 2

Bollinger Bands Width (BBW): Color = (Default: Green [#138484])
- I consider stocks with "BBW >= 4" are at a volatile state and ready for price contraction, but this depends on the parameter values of your choice.


Bollinger Bands %B (%B): Color = (Default: Blue [#62b6ee])
1. %B Above 10 = Price is Above the Upper Band
2. %B Equal to 10 = Price is at the Upper Band
3. %B Above 5 = Price is Above the Middle Line
4. %B Below 5 = Price is Below the Middle Line
5. %B Equal to 0 = Price is at the Lower Band
6. %B Below 0 = Price is Below the Lower Band
