Finding low price of a particular period

[Tulefi]

I need to be able to reference the low price of the 09:00-10:00 H1 period. How do I do this using timestamp. Should I key in 09:00 or 10:00?
Basically at some point later in the day I have some logic that needs to reference the low price of the 09:00-10:00 period.

@tulefi Probably 09:00 but put into a comment so you can check.
