📌 Pre-Market High & Low (RTH Chart Friendly)
What this indicator does

This indicator plots the current day’s pre-market high and low directly on a regular trading hours (RTH) chart, even when Extended Hours are turned OFF.

It is designed for traders who:

Trade during regular session only

Still want pre-market reference levels

Want clean, customizable formatting

The levels are calculated using extended-hours data, then locked at the regular market open and displayed throughout the trading day.
