Session High/Low

189
What it does:
Plots the High and Low of three sessions—Asia (19:00–02:00), London (02:00–08:00), New York (09:30–16:00)—all in UTC-4. After a session closes, it draws a horizontal line starting at the bar where the level first formed, extends it live to the current bar, and shows a label at the line’s end. If price sweeps the level (by wick or close, configurable), the line stops at that bar.

Settings: show/hide sessions, sweep on close toggle, how many past sessions to keep, line style/width, colors per session, and custom label text.
Works on any timeframe. Note: session times are fixed to UTC-4 (adjust if your market uses DST).
