How to stop the line.new() extend conditionally?

[jackbravo]

Hi, I'm new to coding and pinescript, and just know enough to dabble.
I'm trying to make a swing failure indicator using the line.new() function. I was able to create it but I'm not sure how to stop it. Specifically, I'd like the line to stop when there is a close above. Right now, I'm just getting 100s of lines. Any ideas?

Code: Select all

//@version=6
indicator("Swing Failure", overlay=true)

sfw1 = high > high[1] and close < high[1] and close < open
sfw2 = high < high[1] and close < open[1] and close < open and close[1] > open[1]

sfw3 = low < low[1] and close > low[1] and close > open and close[1] < open[1]

// Initialize a horizontal line at a fixed price level
var line hl_line = na  // Track the horizontal line object
var line hl_line2 = na  // Track the horizontal line object

if (sfw1 or sfw2) and barstate.isconfirmed
    hl_line := line.new(x1=bar_index[1], y1=high[1], x2=bar_index + 5, y2=high[1], color=color.rgb(0, 0, 0), width=2, style=line.style_solid, extend=extend.right)

if (sfw3) and barstate.isconfirmed
    hl_line2 := line.new(x1=bar_index[1], y1=low[1], x2=bar_index + 5, y2=low[1], color=color.blue, width=2, style=line.style_solid, extend=extend.right)

Thanks!

Do you want the lines only to extent till a cnadle breaks it? Or do you want to only draw the latest and remove the rest?

Thanks for the reply.
I'd like to keep the current as well as the old ones, unless it's going to cause slowness. I don't need maybe more than 10 or 20.
