Draggable Volume Profile

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.
