INVITE-ONLY SCRIPT
Session Ranges Pro+
Session Range Zones – Professional Edition
OVERVIEW
Professional visualization of the classic opening-range / Initial Balance concept across Asian, London, and Regular (US) sessions.
Displays the high/low of the user-defined opening window as thick, hierarchical filled zones with optional Fibonacci and standard-deviation extensions plus full alerting.
CONCEPT BACKGROUND
Using the high and low of the first 30–60 minutes of a session as key support/resistance is public-domain knowledge that has been standard in institutional trading for decades (Initial Balance, Opening Range, Session Range, etc.).
On TradingView the same principle was popularized under the name “Defining / DealingRange / DR/IDR” by TheMas7er and others.
IMPLEMENTATION & VALUE ADDED
This indicator follows the established, public-domain range-calculation methodology but has been completely rewritten with the following original enhancements:
• Clean, filled High / Mid / Low zones for instant visual hierarchy
• Intuitive Asian / London / Regular session labelling and fully custom timing
• Comprehensive dynamic & static Fibonacci and 50%/100% standard-deviation extensions
• Alert conditions on every zone, midline, opening level, and extension line
• Modern, modular code architecture using arrays and custom drawing functions
• No repainting, lightweight performance on any intraday timeframe
HOW TO USE
Apply to 1–15 min charts. Select desired sessions and formation period (30 or 60 min typical).
Shaded zones serve as primary support/resistance; extensions provide measured-move targets.
CREDIT & TRANSPARENCY
Core methodology: public domain (Initial Balance / Opening Range / Session Range).
Early TradingView popularization of the DR/IDR naming and feature set: TheMas7er **(with thanks to community contributors like bmsitiaan and trading-guide for refinements)**.
**Utilizes PineCoders' VisibleChart library for optimized chart rendering.**
This script uses the same foundational principle and logical input options but is an independent implementation. All visual presentation, zone system, multi-session handling, extension systems, alerting framework, and underlying code structure are original.
