BollingerPercentB

Description

The Bollinger Bands® Percentage B is a technical indicator based upon the Bollinger Bands® study; it plots a histogram showing position of price relative to the bands. It is calculated as percentage ratio of two differences: first one is the difference between the price and the lower band value, second one is the difference between values of upper and lower bands.
