Following a modelisation of the price variation by Fractional Brownian Motion, this indicator increases the width the Bollinger Bands in order to avoid (or minimize) false signals (of entry or exit). For a more complete explanation, please see my blog: http://fractalfinance.blogspot.com/2009/05/from-bollinger-to-fractal-bands.html
