Bollinger Band

Standard deviation of last Close from a p period moving average and standard deviations therefrom

Moving average period

Number if standard deviations from the moving average curve to calculate bands. Use decimal point. Remember that floating numbers use decimal point, not comma, when stating the dev parameter

U=Upper band, L=Lower Band, X=crossing high/low bar

Data series with values according to selected parameter U and L. For X either True or False

For standard deviations from other data series than C, use STDEV().

BolBands(20,2,X) returns TRUE if any band is crossing the high/low bar

BolBands(20,1.5,U) returns the value of the upper band 1.5 standard deviations from the moving average of 20 periods
