ETF-Futures Opening Ratio (Table)

This indicator calculates the opening price ratio between an ETF and its corresponding futures contract using the 9:30 AM New York (RTH) opening price.
The ratio is locked at the official market open and remains fixed throughout the session, providing a stable reference for:
Translating ETF price levels into futures equivalents
Comparing relative value and premium/discount behavior
Maintaining consistent cross-instrument analysis during the trading day
The output is displayed in a simple on-chart table for quick reference and minimal chart clutter.
