tncylyv - Improved Delta Volume Bubble

This script is a specialized modification and structural upgrade of the excellent "Delta Volume Bubble [Quant Z-Score]" by tncylyv.

While the original tool provided a fantastic foundation for statistical volume analysis, this "Zero Float" Edition was built to solve specific visual challenges faced by active traders—specifically the issue of indicators "floating" or disconnecting from price when zooming in on lower timeframes.

The Straight Improvements
This version turns a "Signal Indicator" into a complete "Trading System" with five specific upgrades:

1. Visual Stability (The "Zero Float" Fix)

Original: Used complex coordinates that could desynchronize, causing bubbles to drift or float away from candles on fast charts (1m/5m).

My Upgrade: Implemented "Magnetic Anchoring." Labels and bubbles are now physically locked to the candle wicks. They never drift, overlap, or float, no matter how much you zoom or resize the chart.

2. Cognitive Load (The HUD)

Original: Displayed raw numbers inside colored circles, requiring you to memorize color codes.

My Upgrade: Replaced numbers with Semantic Text Labels (e.g., "ABSORB", "SQUEEZE", "MOMENTUM"). You can read the market intent instantly without decoding it.

3. Regime Adaptation (AI Engine)

Original: Used a fixed threshold (e.g., Z-Score > 2.0).

My Upgrade: Added an Adaptive Learning Window. The script scans recent volatility to automatically raise the threshold during choppy markets (filtering noise) and lower it during quiet sessions (catching subtle entries).

4. Market Memory (Smart Structure)

Original: Signals disappeared into history.

My Upgrade: Draws Support/Resistance Rails extending from major volume events. This helps you visualize exactly where institutions are defending their positions.

5. Robust Data Handling

My Upgrade: Added a Hybrid Fallback Engine. If granular 1-minute data isn't available (e.g., on historical charts), the script seamlessly switches to an estimation model so the indicator never "breaks" or disappears.

Core Logic
Z-Score Normalization: We don't look at raw volume; we look at statistical anomalies (Standard Deviations).

Absorption: Detects "Effort vs. Result"—high volume with tiny price movement (Trapped Traders).

Squeeze: Highlights areas where a breakout is imminent due to volatility compression.

Credits
Original Concept & Code: tncylyv (Delta Volume Bubble [Quant Z-Score]). This script would not exist without his brilliant groundwork.

Modifications: Visual Anchoring, HUD Text System, AI Thresholding, and Structure Rails added in this edition.

This script is open-source to keep the spirit of the original author alive. Use it to understand the "Why" behind the move.
