ARB 18:00–19:00 IST — Lines Only (v6, multi-day)

Draws a simple Opening Range for 24/7 markets using a custom time window. By default it captures the high and low formed between 18:00 and 19:00 IST each day, then locks those levels at 19:00 and extends two horizontal lines to the right. No alerts, no signals—pure levels so you can track breakouts or traps manually.
