fill, fill_area

Syntax Format

open = first
close = second

fill(first, second, name="Filled", color=color.blue)

Overview

The fill and fill_area functions color the area between two plotted lines. They're particularly handy for highlighting overbought and oversold levels, or potential trend reversals — the color can change at the point where the two lines intersect.

Parameters

Parameter	Type	Purpose	Default State
First	series or numeric	First series	-
Second	series or numeric	Second series	-
Name	string	Name of the plot	"fill(first,second)"
Color	color	Color of the plot	"white"

Example

overbought = input(80, "Overbought")
oversold = input(20, "Oversold")

fill_area {
    first = overbought,
    second = oversold,
    color = rgba(255,255,255,0.2)
}
