Opening Range + Session Windows + Volume Profile
May 12, 2026

The Opening Range + Session Windows + Volume Profile indicator provides a comprehensive visual framework for studying intraday market structure by combining opening range levels, configurable session windows, and volume profile analysis. It aims to offer critical volume-based context to price movements, helping traders distinguish between breakouts into high-participation areas versus movements through low-volume zones.
Usage
The Usage section describes how the script can be used to analyze intraday market dynamics. The tool integrates multiple structural elements to provide a "terminal-style" overview of the current session.
- Opening Range Analysis: Use the configurable opening range box to identify the initial balance of the session. Traders often monitor how price reacts to these boundaries throughout the day.
- Volume Profile Integration: The script displays current and previous session volume profiles. High Volume Nodes (HVN) and Points of Control (POC) indicate where participation is concentrated, while Low Volume Nodes (LVN) highlight price areas that the market may move through quickly.
- Session Windows: Visual time blocks (Asia, London, NY AM, NY PM, etc.) can be enabled to highlight specific liquidity windows. This allows for better tracking of session-specific behavior.
- Volume Impulses: The indicator highlights significant participation events with filtered buy/sell labels. These appear only when volume exceeds a specific standard deviation threshold (Z-score), helping to filter out market noise.
Details
The script is constructed to emphasize that the opening range should not be viewed in isolation. Its execution focuses on mapping several key concepts:
- Relative Volume (Z-Score): Instead of showing every volume spike, the script uses a session-based standard deviation calculation to identify true "impulse" moves.
- Node Identification: HVNs and LVNs are calculated based on user-defined thresholds and minimum spacing requirements to ensure the levels shown are structurally significant.
- HUD and Pressure Meter: A terminal-style Heads-Up Display provides real-time data on session state, trend classification, and range size. The pressure meter visualizes current session volume standard deviation.
- Categorization: Labels distinguish between LIVE session levels and PRIOR session levels, allowing traders to carry forward historical context into the current trading day.
Settings
The settings are organized into functional groups to allow for deep customization:
Session
- Main Session: Defines the primary trading hours for profile calculations.
- Opening Range Session: Sets the time window for the initial opening range box.
- Session Timezone: Adjusts the tool’s internal clock to match your local or market exchange time.
Volume Profile
- Show Current/Previous Profile: Toggles the visibility of the session-based volume distributions.
- Rows: Adjusts the granularity of the volume profile histogram.
- HVNs/LVNs Per Session: Limits the number of high and low volume nodes displayed to maintain chart clarity.
- Node Spacing: Determines the minimum vertical distance required between identified volume nodes.
Volume Impulse
- Impulse Session Z-Score: The sensitivity threshold for volume labels; higher values require more significant volume spikes.
- Relative Volume Trigger: A secondary filter based on a lookback average to confirm participation strength.
Visuals & Windows
- Show Terminal HUD: Toggles the session information dashboard.
- Session Windows (Asia, London, NY): Individual toggles to enable or disable specific time-based trading windows with custom transparency and color settings.
- Node Extend Bars: Controls how far to the right the identified volume node levels project.
FAQ
How do I interpret the "Trend State" in the HUD? The HUD classifies the session based on the Efficiency Ratio (KER) and net movement relative to the day's range. It will label the day as "Strong Trend," "Trend," "Chop," or "Building" depending on how price and volume are developing.
What is the difference between an HVN and an LVN? An HVN (High Volume Node) represents a price level where heavy trading occurred, often acting as a magnet or support/resistance. An LVN (Low Volume Node) represents a price "void" where little trading occurred, which price often traverses rapidly.
