ORB (Opening Range Block) is a systematic session-based trading tool designed to define and track the Opening Range (OR), one of the most important intraday reference zones for price discovery and breakout activity.

It captures the high and low of a defined session window and transforms it into a structured framework to analyze volatility, breakout conditions, and directional bias throughout the trading day.

๐Ÿ“Š What it does

This indicator helps you:
-Define the Opening Range High and Low based on a customizable session
-Visualize the range using a dynamic block (box)
-Track the midpoint (50%) of the range
-Detect bullish and bearish breakout events
-Monitor key metrics such as range size, % move, and session status via an info panel

โš™๏ธ How it works

-The indicator captures price action within a defined Opening Range window (e.g. 09:30โ€“09:45)
-Once the window closes, the range is locked and extended forward for analysis
-Breakout signals are generated when price:
-Closes above the OR high โ†’ Bullish breakout
-Closes below the OR low โ†’ Bearish breakout
-A configurable extension system controls how long the range remains active on the chart

๐ŸŽฏ How to use it

This tool can be used to:
-Identify intraday breakout opportunities
-Define key support and resistance zones
-Structure trades around range expansion
-Use the midpoint (50%) as a decision or re-entry level

Typical approach:
-Trade breakouts above/below the Opening Range
-Use the OR as a reference for stop placement
-Combine with trend or momentum tools for confirmation
-Avoid trading inside the range during low volatility conditions

๐Ÿ“Š Info Panel (Real-Time Context)

A built-in table provides a structured view of:
-Opening Range High / Low / Mid
-Range size and percentage
-Session status (building / complete)
-Breakout direction (bullish / bearish / none)
-Timezone and session details

๐Ÿ‘‰ This allows for instant contextual understanding without subjective interpretation

โš™๏ธ Customization
-Fully customizable session window and timezone
-Adjustable box, lines, and midline display
-Configurable breakout signals and colors
-Label visibility and formatting
-Info panel position and size

๐Ÿ“ˆ Key advantages
Clear and structured Opening Range framework
Objective breakout detection
Real-time session and volatility context
Reduces noise and improves intraday decision-making
Works across multiple markets (stocks, indices, crypto, etc.)

๐Ÿง  AlphaScript Integration

๐Ÿ“ Notes

This indicator is a decision-support tool, not a standalone strategy.
