Bollinger Bands® Introduction:
Bollinger Bands are a technical trading tool created by John Bollinger in the early 1980s. They arose from the need for adaptive trading bands and the observation that volatility was dynamic, not static as was widely believed at the time.
The purpose of Bollinger Bands is to provide a relative definition of high and low. By definition prices are high at the upper band and low at the lower band. This definition can aid in rigorous pattern recognition and is useful in comparing price action to the action of indicators to arrive at systematic trading decisions.
Bollinger Bands consist of a set of three curves drawn in relation to securities prices. The middle band is a measure of the intermediate-term trend, usually a simple moving average, that serves as the base for the upper band and lower band. The interval between the upper and lower bands and the middle band is determined by volatility, typically the standard deviation of the same data that were used for the average. The default parameters, 20 periods and two standard deviations, may be adjusted to suit your purposes.

October 2014 Excerpt
I strongly suspect that we have seen the momentum low for the correction. In ideal terms, a W bottom is comprised of a momentum low followed by some sort of bounce/consolidation and then a final price low. In terms of Bollinger Bands, that usually means a low outside the lower BB followed by a low inside the lower BB, %b less than zero on the momentum low and greater than zero on the price low. We expect that a complete/sustainable market bottom formation will take at least a week to sketch itself out.
