Draggable Volume Profile
- Indicators
- Version: 1.31
- Updated: 13 September 2026
Short Description
Drag two lines to any chart range for an instant Fixed-Range Volume Profile (POC, Value Area VAH/VAL) featuring Delta Coloring, Developing Profile tracking, Initial Balance, HVN/LVN, and Retest Rays.
Detailed Description
The Fixed-Range Volume Profile & Delta Analyzer answers a foundational market structure question: At which price did the most trading activity actually occur within a specific timeframe?
Simply drag the two vertical reference lines ( START and END ) anywhere on your chart to isolate any trading range—such as an intraday session, a consolidation phase, or a major news event. The indicator slices the selected area into price buckets and builds a precise horizontal volume histogram.
Designed for active traders who demand speed and accuracy, this tool features an incremental dual-layer calculation engine. It processes historical data smoothly without screen flicker, freezing, or lagging during volatile market conditions.
Key Technical Features & Capabilities
-
CME-Standard Value Area Calculation: Uses the official Market Profile "pair" comparison rule to expand from the Point of Control (POC), identifying true 70% value areas rather than relying on simplified approximations.
-
Delta Bias Overlay & Volume Share: Color-code histogram bars based on aggressive buyer vs. seller volume bias. Contiguous order-flow zones are grouped automatically, showing consolidated percentage shares at key volume peaks.
-
Developing Profile Tracking: Step the POC, VAH, and VAL forward chronologically across the dragged range to observe how fair value shifted over time.
-
Initial Balance (IB) Display: Highlights the high/low range of the initial session minutes (e.g., first 30 or 60 minutes) to monitor institutional auction expansions.
-
High & Low Volume Nodes (HVN / LVN): Automatically detects market acceptance (HVN) and rejection/liquidity gaps (LVN), projecting LVN support/resistance levels forward.
-
Naked / Virgin Level Projection: Projects historical POC, VAH, and VAL levels to the right until a future bar trades through (retests) them.
-
Optimized Performance: Adaptive coarsening handles ranges beyond 5,000 bars easily while retaining exact volume totals.
-
Intrabar Live Updates: Keeps tracking volume live when the END boundary is snapped to the current forming bar.
Practical Use Cases
-
Auction Market Theory Trading: Identify high-volume fair-value zones (POC) where price tends to mean-revert, as well as low-volume rejection areas (LVNs) where price moves rapidly.
-
Breakout & Target Identification: Monitor VAH (Value Area High) and VAL (Value Area Low) boundaries to trade rejections back into value or catch high-momentum breakouts.
-
Session Structure Analysis: Use the Initial Balance (IB) lines alongside Developing POC tracking to evaluate early-session bias and institutional expansion.
Input Parameters & Customization
-
Instance Tag: Assign a unique tag when running multiple copies on the same chart to keep individual profiles independent.
-
Histogram Styling: Choose between Filled, Outline, or Dot-Line styles with customizable colors, widths, and bucket counts (50 to 300+).
-
Min Bucket Pixel Height: Automatically adjusts bucket density so histogram rows render clearly on high-resolution screens without visual blurring.
-
Interactive Controls: Toggle the entire display with a single click using the on-chart [VP ON/OFF] button, or click the gold POC line directly to show/hide VAH/VAL boundaries.
