ROC+ADX Trend & Momentum System

### Code Analysis: ROC+ADX Trend & Momentum System (v5 Pine Script)
#### **Core Function**
This Pine Script indicator integrates **Rate of Change (ROC)** and **Average Directional Index (ADX)** to build a professional trend-momentum trading system, which identifies trend strength, momentum changes, price divergences and generates actionable long/short trading signals for financial markets (stocks, crypto, forex). It features coordinated visual display, adaptive volatility adjustment and a comprehensive scoring mechanism for trend evaluation.
#### **Key Features (Concise)**
1. **Hybrid Indicator Logic**
Combines **ROC (12/6-period, EMA-smoothed)** (measures price momentum) and **ADX (14-period)** (identifies trend strength/direction, with +DI/-DI for trend bias), forming a dual-dimension analysis of trend + momentum.
2. **Adaptive Dynamic Threshold**
Adjusts momentum thresholds in real time based on **14-period ATR volatility**; higher market volatility raises thresholds, lower volatility lowers them, ensuring signal accuracy across different market conditions.
3. **Multi-Category Trading Signals**
Generates 4 core signal types: trend breakout (long/short), momentum boost/drop, trend reversal, and price-ROC bullish/bearish divergence, all filtered by ADX trend validity.
4. **Comprehensive Trend Scoring System**
Calculates a **0-100 trend score** (integrates ADX strength, ROC momentum, direction consistency, momentum persistence) and classifies trend intensity into 5 levels (Extreme/Strong/Medium/Weak/None).
5. **Coordinated Visual Display**
Supports scalable unified display for ROC & ADX values (custom scale factors), with color-coded lines, momentum histograms, heatmap background and reference lines for intuitive trend judgment.
6. **Informative Dashboard & Alerts**
Embeds a top-right info panel showing real values (ROC, ADX, volatility), trend level and active signals; includes multi-tier alert conditions for all key signals (breakout, reversal, divergence).
7. **High Customizability**
Full input configurability for all core parameters (periods, thresholds, scale factors) and visual toggles (show/hide ROC/ADX, signals, heatmap, reference lines).
#### **Technical Highlights**
- Uses EMA smoothing for ROC/ADX to reduce false signals;
- Identifies ROC momentum & acceleration for precise trend phase judgment;
- ADX grading (strong/weak/oscillation) filters invalid signals in sideways markets;
- Color-coded elements (lines, histograms, heatmap) reflect real-time trend/momentum status;
- Non-overlay layout ensures clear separation from price charts, optimized for multi-screen analysis.
