Premarket High/Low (Horizontal Rays)

2025年5月21日

=== 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.

Updated:
The labels for PM High and PM Low now dynamically update during the premarket session as new highs or lows are reached. The rays and labels move in real time without waiting for the premarket session to end.

リリースノート

Updated from the original v5 script to Pine Script v6 and improved premarket high/low accuracy across all chart timeframes.

Key changes:
- Converted script to Pine Script v6.
- Added internal lower-timeframe calculation, defaulted to 1-minute, so PM High/Low remain accurate on higher chart timeframes.
- Added optional forced extended-hours data support.
- Replaced fixed timestamp logic with configurable session inputs.
- Improved drawing efficiency by updating existing lines and labels instead of deleting/recreating them every bar.
- Added time-based ray positioning for better multi-timeframe compatibility.
- Added optional price display in labels.
- Added separate PM High/Low line color controls.
- Added breakout alerts for crosses above PM High and below PM Low.
