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.

September 2014 Excerpt
Gold bullion, after setting up for a breakout from a potential base, is now back probing the lows for support. Silver is actually in worse condition, just pennies away from making a new multi-year low. Platinum is trading a little higher in its sideways pattern and the only star of the show, palladium, is selling off after having made new highs. The industrial metals aren't doing any better either; high-grade copper recovered a bit after recording a new multi-year low, but hasn't been able to build on its bounce in any real manner. Over on the London Metals exchange, we find aluminum, copper, lead, nickel and zinc all in recent short-term down trends. Aluminum and zinc had been in up trends, lending some credence to the economic recovery theory, but all five LME metals have rolled over now. This could be a short-term correction, but with all five metals on the downside and so much other confirmation it seems like something more.
