Premarket High/Low Rays - RTH Safe
Premarket High/Low Rays (04:00–09:30)
This indicator is designed for intraday traders who operate in regular trading hours (RTH) and need access to key premarket levels without enabling extended hours on the chart.
⸻
Overview
The script automatically calculates:
• Premarket High
• Premarket Low
from 04:00 to 09:30 AM (New York time) and projects these levels into the regular session.
At the market open (09:30), it draws two horizontal rays that extend to the right:
• Premarket High
• Premarket Low
These levels remain visible throughout the trading session.
⸻
Key Features
• Works without Extended Hours enabled
• Uses internal data to calculate premarket range
• Draws clean ray-style levels (extend.right)
• Updates automatically each trading day
• No repainting
• Lightweight and optimized for intraday use
⸻
Purpose
Premarket levels are critical reference points for:
• Breakouts
• Rejections
• Liquidity zones
• Intraday bias confirmation
This indicator allows you to integrate that context directly into your RTH workflow without cluttering your chart.
⸻
Customization
You can adjust:
• Line color (High / Low)
• Line width
• Line style (Solid / Dashed / Dotted)
• Label visibility
• Price display on labels
⸻

⸻
Notes
