The Adaptive Volume-Delta Score (VDS) is a technical analysis tool for the statistical classification of volume-delta activity. It utilizes an Adaptive-Switch Logic that toggles between historical bar reconstruction (request.security_lower_tf) and a real-time Rolling-Window Live-Tracker.
🛠 Core Functionality
1. The VDS Engine (Statistical Mapping)
Wick-Weighted Delta: The calculation is based on wick-weighting: (close-open)/range * volume. This weights the delta according to price displacement within the bar.
Symmetrical Mapping (-4.5 to 4.5): Raw values are statistically categorized via ta.percentrank and mapped onto a fixed scale.
+4.5 (100% Rank): The absolute maximum within the chosen lookback period.
+2.25 (75% Rank): Significant activity relative to the period.
0 (Median): The statistical midpoint (50% Rank).
-4.5 (0% Rank / Min.): The absolute floor of activity for the period.
Visualization Logic: This mapping is primarily used to plot volume activity and delta aggression within the same visual space, providing a consistent reference frame for comparing relative dominance.
Context Dependency: Signals are not absolute recommendations. The significance depends heavily on the Lookback Period, Thresholds, and the specific market environment.
2. Adaptive Logic & Data Integrity
Signal-Bridge: On lower timeframes (LTF), the indicator simulates the behavior of the Main Timeframe (Main-TF) using a rolling window. This allows for the observation of delta development while the bar is still forming.
🛡️ Integrity Dashboard: Visualizes the statistical consistency between live data and the historical baseline. Deviations (e.g., due to Pine Script's 5000-bar limit) are displayed transparently as warnings.
3. Dynamic Alert System
Automation: Alerts utilize the alert() function with the "Any function call" setting.
Intelligence: Messages are fully dynamic, reporting the mode (Live vs. History), signal type, safeguard status, and data integrity.
🚀 Quick Calibration Guide
Sensitivity: A longer Lookback Period stabilizes the statistics; a shorter period makes the score more reactive to short-term volume spikes.
Threshold Setup: Calibrate the Dominance Threshold (default 3.0) to isolate extreme aggression. Use the Volume Threshold to ensure a minimum level of market participation.
Visual Match: Activate the Price Chart Overlays and adjust your thresholds until the markers (Diamonds) correspond with your individual market interpretation.
Dashboard Check: Monitor the Confidence Score. If red warning values appear, consider adjusting your Lookback or Timeframe to maintain a stable statistical foundation.
🎨 Visual Guide: Understanding the Scale
Navy/Blue Columns: Standard activity within the selected statistical window.
Gray Columns: Phases below the Low Volume Threshold, indicating low relative market participation.
Lime/Fuchsia (Dominance): Occurs when volume and delta simultaneously exceed the defined thresholds (Aggression).
Olive/Maroon (Divergence): Period delta is positive/negative while price action is opposite (Decoupling/Absorption).
Diamonds: Optional projection of oscillator signals directly onto the candles in the price chart.
⚠️ Important Technical Notifications
The "Signal Bridge" (Rolling vs. Fixed Window):
HTF-Request Mode (Fixed): Measures delta starting from the candle open (e.g., 12:00 PM).
Live-Transfer Mode (Rolling): Analyzes a sliding window (e.g., the last 120 minutes). This provides a Lead-Time Advantage, detecting aggression as it happens regardless of the HTF clock. Both modes converge at the HTF bar close.
Data Integrity & Anomalies:
Session Gaps: High Main-TFs (like D1) can be affected by irregular session hours (e.g., Forex Sunday). Always monitor the Confidence Score (🛡️).
Replay Mode:
Displays "No Stat. Control" if historical LTF data is unavailable. We prioritize data honesty over estimated data.
🔔 How to set Alerts (Smart Signals)
Preparation: Open the VDS settings. Under "Alert Settings", choose which signals should trigger: Dominance, Divergence, or both.
Condition: Select "Adaptive Volume-Delta Score...".
Trigger Logic: Change setting to "Any alert() function call".
Frequency: Managed by the script (once_per_bar_close) to ensure statistical honesty.
Timeframe Choice: Use the Main-TF for final confirmed signals, or a Lower-Timeframe for Live-Tracker early warnings.
📊 Statistical Transparency (Data Window)
Raw metrics are displayed exclusively in the TradingView Data Window to keep the chart clean:
Runtime-Safe LTF: The analysis interval currently in use.
Max Safe Lookback: The mathematical limit for your current setup (5,000-bar ceiling).
Active Bar Limit: The actual usable data foundation.
Converted Sum of LTF Request Bars: The historical baseline used as an anchor for the Live-Tracker.
Relative Live-Data Size: Numerical basis of the Confidence Score (100% = Perfect Integrity).
Overall Requested Bars: Total data points analyzed within your Lookback Period.

Nota Keluaran
v1.1 - Aggression Engine RefinementOptimization: Removed redundant volume-weighting from the Delta-Ranking.
Result: Improved responsiveness and lead-time. The VDS now detects high-conviction aggression earlier, specifically improving the detection of setups prior to a Break of Structure (BOS in the lower Timeframe).
Linear Scaling: The score now provides a more direct representation of market intent by focusing on the statistical rank of the volume-delta itself.
Source Code: Added direct links to the Adaptive Suite (IAI) and profile in the header for easier navigation.
Default optimization: Set High Volume Threshold to 0.0 (Median) for a more intuitive balance between aggression and participation.
