Ultimate S&D (Pro Edition)

**Institutional Supply & Demand (Auto-Cleaning & Freshness Tracking)**

This indicator is designed for Price Action and Futures traders who require a clean, objective view of Institutional Supply and Demand zones. unlike standard indicators that clutter the chart with historic levels, this script focuses on **"Smart Mitigation"**—automatically removing zones that have been invalidated to keep your chart pristine.

### Key Features:

**1. 🏦 Institutional Imbalance Detection**
The script identifies **ERC (Extended Range Candles)** and momentum shifts to locate true institutional interest. It automatically marks the "Base" preceding the explosive move as a valid zone.

**2. 🧹 Smart Auto-Invalidation (Clean Chart Logic)**
Most S&D indicators leave old, broken zones on the chart. This script actively monitors price action:
* **Supply Zones:** Automatically deleted if price breaks above the zone's high.
* **Demand Zones:** Automatically deleted if price breaks below the zone's low.
* **Result:** You only see active, defendable levels.

**3. 🔄 Zone Freshness Tracking (Fresh vs. Tested)**
Visual cues help you gauge the probability of a setup:
* **Fresh Zones:** Solid borders with darker colors. (High Probability)
* **Tested Zones:** Once price touches a zone but holds, the zone turns **Dashed** and lighter in color, labeled as "(Tested)". (Lower Probability / Caution required)

**4. 🏷️ Dynamic Timeframe Labeling**
Zones are automatically labeled with the chart's timeframe (e.g., "1H Demand", "15m Supply"), making it perfect for Multi-Timeframe Analysis (MTF) and sharing screenshots.

**5. 🔔 Integrated Alerts**
Never miss an entry. You can set alerts to trigger the moment price enters a Fresh or Tested zone.

### ⚙️ Settings Guide:

* **Imbalance Strength:** Controls how strict the filter is. Higher values (e.g., 4.0) only show the strongest institutional moves. Lower values (e.g., 2.0) show more local zones.
* **Lookback Period:** How many bars are used to calculate average volatility.
* **Zone Extension:** How far the boxes extend to the right (auto-limited to prevent clutter).

### 🎯 How to use:
Recommended for use as a "Confluence Tool." Use your daily bias and trend analysis first, then use this script to identify precise entry zones on 1H, 15m, or 5m charts.
