Hello Traders,
i've been looking into the existing studies something that would allow me to draw an opening range that would stop
drawing once a certain amount of ticks would be reached ( no luck until now), is there anything like that?
(for exemple: session open at 156 it creates a first line then price goes to 158 so i now have two line : one low 156 and one high 158 and then it goes to 166 (so a 10 ticks range)) at this stage i want the range to remain like with the two lines being visible until the end of the day.

There is no native study that will do what you want. It would require programming a custom study, or by using the Spreadsheet Study study.

ok thanks again tomgilb.

If you're using the session open, why not just use the Horizontal Line at Time + Bands/Envelope set to +/- 10 ticks?
