Brownian Bands revisited?

Further to my most recent post there have been a few anonymous comments suggesting that Brownian bands are more useful than I supposed. In response I have added a contact form to this blog ( on the right ) so these anonymous readers may contact me if they wish. I am curious to learn how they may be using Brownian bands. I might also add that I have thought of creating a new indicator ( a kind of randomness measurement oscillator ) based on the Brownian bands concept.
