OptionalcolumnOptionallookbackLook-back for the highest/lowest of column, in bars. Default
10.
OptionalperiodLength of each average in the stack, in bars. Default 2.
OptionalprefixColumn-family prefix — appends ${prefix}, ${prefix}Upper and
${prefix}Lower. Default 'rbo'.
OptionaltypeWhich moving average the stack uses. Default 'sma'. Spelled
type, not maType, by deliberate exception to the package's rule
(type when the columns ARE the averages, maType when an average
sits inside a study): this option IS rainbow's type, passed
through unchanged to the same ten-stage stack, and a consumer who runs
both studies passes one spelling to both.
Source column — read as the price, as the stack's input, and as the range the reading is normalised by. Default
'close'.
