linefill

How do you shade the space between two lines? Call linefill.new with both lines and a colour. The fill follows the lines wherever they move, and goes when either line is deleted.

//@version=6
indicator("50-bar channel", overlay = true)
hi = ta.highest(high, 50)
lo = ta.lowest(low, 50)
var line top = line.new(na, na, na, na, color = color.green)
var line bot = line.new(na, na, na, na, color = color.green)
if barstate.isfirst
    // Made once: moving the lines moves the fill.
    linefill.new(top, bot, color.new(color.green, 85))
if barstate.islast
    line.set_xy1(top, bar_index - 49, hi)
    line.set_xy2(top, bar_index, hi)
    line.set_xy1(bot, bar_index - 49, lo)
    line.set_xy2(bot, bar_index, lo)

A linefill made on the same two lines as a live one, in either order, replaces it. One whose line was deleted, or that was replaced or deleted itself, leaves the chart and linefill.all, and its getters read na. A line the line count takes leaves its linefill in place.

color series color	The fill's colour.

linefill.get_line1

Pine v6

linefill.get_line1(id) → series line

Also a method: id.get_line1().

The fill's first line.

Parameter	Description
id series linefill	The linefill.

linefill.get_line2

Pine v6

linefill.get_line2(id) → series line

Also a method: id.get_line2().

The fill's second line.

Parameter	Description
id series linefill	The linefill.

linefill.set_color

Pine v6

linefill.set_color(id, color) → void

Also a method: id.set_color(color).

Sets the fill's colour.
