The Bollinger Bands are what is called a technical trading tool and are widely used in the capital markets (including Forex) and were created by John Bollinger in the early 1980s. These band technology was designed based on the need for adaptive trading bands and the discovery that the volatility in the markets was a dynamic phenomenon, not a static one that was widely believed at the time.

Bollinger Bands consist of a graph with three curves drawn in relation to the currency pair prices. The band in the middle is a measure of the intermediate term, and is usually a simple moving average, which serves as the base for the upper and lower bands. The interval between the upper, lower and middle band is determined by the volatility in the market, usually the standard deviation of the same data used for the moving average. The default parameter is 20 periods and two standard deviations above and below the middle band; course this can be adjusted to suit your needs.

In summary, the purpose of Bollinger Bands is to provide a relative definition of high and low price. By definition prices are considered to be high when touching the upper band and low when in contact with the lower band. This relative definition can be used by the Forex trader to compare price action and a very useful indicator for the purpose of the trader is to arrive at rigorous buy and sell decisions.
