Here is a filter phrase I have found useful. It provides a simple way to display in a column the Bollinger Band Range Percentage value of a stock's closing price.
Or it can be used to find stocks at a particular point within the range of the lower and upper Bollinger bands. It is expressed as a percentage.
set{BollA, Close - Lower Bollinger Band(20)} and set{BollB, Upper Bollinger Band(20) - Lower Bollinger Band(20)} and set{BollC, BollA / BollB} and set{BBRangePct, BollC * 100} and add column BBRangePct
It generates a column that can be toggled to order the Bollinger Band Range Percentage results in ascending or descending order.
A result of 112 for instance would be a stock that closed above the UBB, one of -20 would be one below the LBB. A result of 100 would be exactly at the upper BB, and one of 50 would be at the midrange (or sma20). A result of 0 would be exactly on the LBB.
[Note to SF Techs: I would like to request that you consider this or some other formulation of the Bollinger Band Range as an additional indicator for SF use].
