Premarket High/Low (Horizontal Rays)=== Script Description ===
This TradingView script automatically detects and displays the high and low prices
during the premarket session (04:00–09:30 Eastern Time) for the current trading day.
It draws horizontal rays that extend across the chart and labels them as "PM High" and "PM Low".
These markers are refreshed daily and only apply to today's session.
The script also provides full customization for:
- Line color, width, and style (solid, dotted, dashed)
- Label text color, background color, size, and style (left, right, up, down)
Time note: This script assumes data aligned with U.S. market hours.
