OPEN-SOURCE SCRIPT
Rango Pre-Apertura (8am-9am)

Overview
This indicator is specifically designed for the index trading community, with a focus on US30 (Dow Jones). It centers on the concepts of "Capital Injection" and "Opening Traps," automatically identifying the most critical liquidity levels prior to the New York Open (09:30 AM EST).
Indicator Logic
The script operates on the premise that the range formed between 08:00 AM and 09:00 AM EST acts as a key accumulation or manipulation zone before the official session. By marking these levels, traders can visualize where institutional algorithms are likely to seek liquidity before the day’s primary expansive move begins.
Key Features
08:00 - 09:00 AM Range: Automatically calculates and projects the exact High and Low of this pre-market window.
Previous Day Levels (PDH/PDL): Identifies the Previous Day High and Low as primary zones for External Liquidity (BSL/SSL).
Visual Clarity: Lines are projected only until 01:00 PM EST to keep the chart clean for post-session analysis.
Professional Styling: Uses non-continuous plots to avoid visual noise and diagonal line "bleeding" between trading days.
How to Trade with this Script
Mapping: Identify whether the price opens above or below the 8:00 AM range.
The Trap: Look for liquidity sweeps (Stop Runs) of the marked lines exactly at 09:30 AM.
Confirmation: Combine this indicator with price action to detect "Force Invalidations" (Engulfing patterns) at H1 or H4 Points of Interest (POI).
