Crawl4AI Crypto Trading Analysis Demo
Author: Unclecode
Date: 2024-03-15

This script demonstrates advanced crypto market analysis using:
1. Web scraping of real-time CoinMarketCap data
2. Smart table extraction with layout detection
3. Hedge fund-grade financial metrics
4. Interactive visualizations for trading signals

Key Features:
- Volume Anomaly Detection: Finds unusual trading activity
- Liquidity Power Score: Identifies easily tradable assets
- Volatility-Weighted Momentum: Surface sustainable trends
- Smart Money Signals: Algorithmic buy/hold recommendations
