I would like to be able to test and filter the value returned from the standard Bollinger %B function against price. Quite often, I want to find items that are just under the top line of the Bollinger at, say, > 96% or just above the bottom line of the Bollinger at, say, < 4%.

Whilst the existing functionality is good in that you can filter for items above or below the Bollinger lines, I miss out on certain opportunities that would be easily taken care of by %B. I don't mean a visual indicator (although that would be OK), I want a simple return value from a %B function.

Thanks!
