fixnan() - Pine Script Function

Overview

fixnan() forward-fills a series by replacing each na with the last non-na value. Use it when data sources produce occasional gaps.

Syntax

fixnan(source) → series _

Parameters

Name	Type	Description
source	series _	Series to forward-fill (any type except tuples).

Returns

Series without na gaps.

Remarks

• Unlike nz(), fixnan() forward-fills the last non-na value but does not substitute an arbitrary default when all previous values are na.
• Works on numbers, colors, strings, and bool series.

Examples

//@version=6
indicator("fixnan example", overlay=false)

extClose = request.security(syminfo.tickerid, "60", close)
filled   = fixnan(extClose)

plot(extClose, "Raw", color=color.new(color.red, 40))
plot(filled, "Forward filled", color=color.blue)
