John, ________________________________________________ Bollinger Bands Description Bollinger Bands create an envelope around price. The shape of the envelope is based on a simple moving average. The width of the envelope is determined by the sample standard deviation multiplied by a user-defined factor. The Bollinger Bands widen with increasing price volatility and narrow in times of market inactivity. The BB functions plots the Moving Average, Bollinger Band High and Bollinger Band Low. Price typically moves within the Bollinger Band envelope. Breakouts above or below the band can signify major moves. In addition, the bands and the moving average can be used as support and resistant points. Parameters Name Type Default Range Period Integer 20 1-199 Bollinger Band High Standard Deviation Multiplier Floating Point 2 1-9 Bollinger Band Low Standard Deviation Multiplier Floating Point 2 1-9 Formula Moving Average = S Price N Period / N Period Sample Standard Deviation = sqrt(S (Price - MA)2 N Period / N Period) ) Bollinger Band High = MA + Sample Standard Deviation * SDM(BBH) Bollinger Band Low = MA + Sample Standard Deviation * SDM(BBL)
