Trading session High/Low (Lumiere)

Trading session High/Low

What it does:
Plots the High and Low for each session (Asia, London, New York) as horizontal zones that “snap” to the first true extreme of the session and then extend right.

Key points:

Snap‑to‑extreme only: Lines don’t draw at the open; they appear only once price makes a new session high or low, and anchor exactly at that bar.

Persistent until next session: Once drawn, each session’s lines stay on the chart after the session ends, and are cleared only when that same session next opens (or when you hide it).

Three configurable sessions:

Asia: 18:00–03:00 (UTC‑4)

London: 03:00–09:30 (UTC‑4)

New York: 09:30–16:00 (UTC‑4)

Customizable appearance:
You can toggle each session on/off, choose its color, and set line width.

The time that is already set on the different sessions is based on the standard session open/close. If you want to change it, it will refer to the NY time, UTC -4.
