Functions

talib.variance()

Variance of `source` over `length` bars. An optional `biased` flag chooses between the biased and unbiased forms of the calculation. `talib.stdev` has no such flag.

Syntax

                talib.variance(series float source, series int length, series bool biased) → series float

Arguments

source required series float The series to measure.

length required series int How many bars the window covers.

biased series bool Optional flag choosing between the biased and unbiased forms.

Return Type

series float

Example


          indicator("Variance Indicator", overlay=false)
length = input(20, "Variance Length")
varianceValue = talib.variance(close, length)
plot(varianceValue, color=color.blue, title="Variance")
