You can use the built-in hour and minute variables to figure out if the current bar is 08:00.

Then store the open price in a var variable.

var float open_price = na
is_start = (hour == 8) and (minute == 0)

open_price := is_start ? open : open_price
plot(open_price)

And how do you draw the horizontal line, since when compiling it gives an error? Thanks – Tecleador Nov 22 '22 at 21:12
I test this code on pinescript v5, all is ok and the horizontal line is drawn. – G.Lebret Nov 23 '22 at 04:36
@Tecleador what error are you getting? It should compile fine. Had tested it before posting my answer. – vitruvius Nov 23 '22 at 08:48
sorry for not answering sooner, what I need is an hline at the opening price of 8 in the morning but what you have given me does not show it to me Thank you – Tecleador Nov 23 '22 at 17:57
and save the value of that opening to later create other hlines based on that value – Tecleador Nov 23 '22 at 17:58

an example

//@version=5 indicator("Cotas Diarias", overlay=true)
_h = 2 // Hour: 7 _m = 0 // Minute: 0 inWindow = (hour(time) == _h) and 
(minute(time) == _m)
var line apertura = na var line R1 = na
if (inWindow) apertura := line.new(bar_index, open, bar_index + 1, open, 
extend=extend.right, color=color.rgb(4, 150, 41), width=4) 
line.delete(apertura[1])

That creates a horizontal line in the opening price of the bar at 8 in the morning and the next day it does the same
