B21V21

This Pine Script is designed to provide both previous-day reference levels and real-time market data, making it suitable for live trading applications. It automatically retrieves all key historical levels—such as PDH, PDL, PDC, and PDO—for the currently selected strike as well as the corresponding opponent strike.

The script allows users to compare two instruments or strikes by selecting either a self-opponent view or any required strike for cross-analysis. Important intraday levels are displayed dynamically during live market conditions, enabling traders to make informed and timely decisions.
