Horizontal line until crossover/crossunder

[Zahneck]

Can anyone help me with this.
What chat gpt provides doesn‘t work out.

I want to build an Indicator that prints the daily highs and lows for past several days that start at the highest bar to the bar as it crosses over/under

Sure! Its pretty simple to build such indicator.
Do you have any other requirements?
