Daily Market Bias Highlight

This indicator is designed for Pine Script (TradingView) to automate your daily market bias assessment and highlight the critical execution window just before the New York open.
Core Functionality
15-Minute Pre-Market Window: Specifically highlights the background of your chart from 08:15 to 08:30 CT (America/Chicago), providing a visual countdown to the market open.

Daily Bias Logic: Automatically calculates whether the current sentiment is Bullish or Bearish based on price action from the previous two days.

Dealing Range Analysis: Uses a customizable lookback (defaulting to 20 days) to identify the "Equilibrium" (50% level) of the current price range.

Bias Rules
The indicator evaluates the daily trend using the following logic:

🟢 Bullish Bias: Triggered if price swept below the previous day's low and closed back inside (reclamation), or if the market simply closed above the previous day's high.

🔴 Bearish Bias: Triggered if price swept above the previous day's high and closed back inside (rejection), or if the market closed below the previous day's low.

Visual Elements
Background Highlight: Changes color during the pre-market window (Green for Bullish, Red for Bearish).

Range Markers: Plots the Range High, Range Low, and Equilibrium levels to show where price is sitting relative to the broader 20-day "Dealing Range".
