As of my quick disappoinment in future looking Hurst bands (posted somewhere here), I decided to try the same idea with fast and long period bands on one chart. Surely, that might have been done the numerous times before me. But I added nice looking clouds :)
Trade this as usual BB but sinergizing with each other, and use confirmations from other indicators or techniques of course.

(just drop formula on your price chart and adjust periods and widths to fit chart turning-points)
