Functions

talib.roc()

Rate of change of `source` measured across `length` bars. Where `talib.change` gives the difference, this gives the rate.

Syntax

                talib.roc(series float source, series int length) → series float

Arguments

source required series float The series to measure.

length required series int How far back the measurement reaches.

Return Type

series float

Example


          indicator("Rate of Change (ROC)", overlay=false)
length = input(10, "ROC Length")
rocValue = talib.roc(close, length)
plot(rocValue, color=color.blue, title="ROC")
hline(0, "Zero Line", color=color.gray)
