Not only will Bollinger Bands help traders make better trades, they will also encourage traders to combine other methods of technical analysis to come about the best prediction possible.

Percent B came from the technique of Stochastics and identifies the location of the price. Percent B acts as a compass for traders letting them know where they are in relation to the upper band, the middle band and the lower band. In order to calculate Percent B exactly, it is given the value of 1 for the upper band and 0 for the band at the lower end. The calculation using the Percent B function is that Percent B is equal to the last price for a security minus the lower Band. This difference is then divided by the difference of the upper ...
