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.

December 2014 Excerpt
Without a doubt the most interesting international market at present is Shanghai, which has rocketed to a four-year high and is on the verge of breaking out of a base with measuring implications well into new high territory. The move Shanghai made is even more interesting by being just about the perfect contrarian move; everyone 'knows' that the world's stock markets are headed down, just as everyone 'knows' that China is a mess in just about every way. Yet, oddly, perhaps because it is not supposed to, the Shanghai Composite is muscling its way higher and before anyone got the message it was 66% above its 2013 lows.
