plot a "price level line"

[CW1]

Hello, I'm new to the forum and I'm not sure if this is a good place to post this but here goes.
I'm would like to automatically plot a "price level line" (just as if I used the price level tool) on the open of a new bar. The price level line needs to extend to the right only from the bar it plots on. This would be the first step of my project. Thanks

hello and welcome.
yes, you found the questions section, the right spot for questions.

this will plot a line from a price level of 1 bar, and extend to the right.
. can pick how many bars back. 0 = current bar
. can chose price type. default is open

the x formula, looks at future bars, to find the last bar with a price and the bar after it that doesn't have a price.
the line formula saves the price value and keeps it till the right edge of the screen (through the expansion area)

#barx_openline

def na = double.nan;
def bn = barnumber();

input bars_back = 0;
def x = (!isnan(close[-bars_back]) and isnan(close[-(1+bars_back)]));
input price = open;

def line = if bn == 1 then na
 else if x then price
 else if isnan(close) then line[1]
 else line[1];
plot z = line;

input test_vert = no;
addverticalline(test_vert and x, "-");
