Continuing my dig through the old favorites box I though it would be nice to revive our Swami indicators thread so here is the Swami Bollinger Bands Oscillator coded by Mladen

As explained by Mladen:
This is swami version of a kind of a bollinger bands oscillator. It constructs a generic indicator value too (it is an average of all oscillators calculated from StartWidth to EndWith lengths). If you want to speed it up, you can do a couple of things. Lessen the PriceSmoothing parameter value, lessen the Deviations parameter value or change the PriceSmoothingMethod. Default parameters used are something I liked at a first glance, but maybe some other symbol will need some other settings.
