Ultimate ORB Architect

The Ultimate ORB Architect is a high-precision volatility and range-expansion tool designed for intraday traders. It specializes in the Initial Balance (IB)—the high and low established during the first session of the trading day—and projects mathematically significant expansion levels for price discovery.

Unlike standard opening range indicators, this script utilizes a Smart-Swap Calculation Engine, allowing traders to toggle between Standard Deviation and Fibonacci sequences instantly while maintaining a clean, professional chart aesthetic.

Key Features

1. Dual Calculation Engines
- Standard Deviation Mode: Projects targets based on whole-unit range expansions ($1.0, 2.0, 3.0, 4.0$). Ideal for Mean Reversion and classic IB breakout trading.

- Fibonacci Sequence Mode: Projects targets based on the Golden Ratio and its extensions ($0.618, 1.618, 2.618, 4.236$). Perfect for trend exhaustion and harmonic target setting.

2. "Smart-Swap" Internal Levels
The script intelligently adapts its internal support and resistance lines based on your selected mode:
-In SD Mode: Displays 25% and 75% (Quarters)—the standard institutional "Fair Value" levels within a range.
-In Fibonacci Mode: Displays 38.2% and 61.8% (Golden Retracements)—the primary zones for range-bound reversals.

3. Institutional Timing & Projection
Time-Locked Execution: Custom sessions allow you to define the ORB window (e.g., the first 30 or 60 minutes).
5:00 PM EST Hard Cutoff: To prevent "infinite lines" that clutter your chart, all projections are hard-coded to terminate at the NYSE close (17:00 EST), providing a clear visual end to the trading day.

4. Professional Visual Suite
Adaptive Lookback: Choose to view only today’s action for a "clean" chart or look back up to 5 days to analyze historical range behavior.
Customizable Hierarchy: Every level—from the 50% Midpoint to the Level 4 "Runner"—features independent color, style (Solid/Dashed/Dotted), and label size controls.

How to Use
Define the Session: Set your ORB Session (default is 09:30–10:30).

Select Your Mode: Use the Calculation Mode dropdown to switch between Fibonacci or Standard Deviation targets depending on the day’s volatility.

Monitor the Midpoint: The 50% line (Mid) acts as the "Pivot of Power." Price holding above the Mid indicates bullish bias; below indicates bearish bias.

Target the Runner: Use the Level 4 Runner as your ultimate take-profit on high-momentum trend days.
