## What SignalFuse Does

- Generates directional trading signals (long/short/neutral) for BTC, ETH, SOL, DOGE, PEPE, WIF, BONK, ARB, OP, AVAX with entry price, take-profit, and stop-loss levels
- Runs ModernFinBERT sentiment analysis on crypto social and news data
- Classifies the macro regime as risk-on, risk-off, or neutral using multi-factor economic indicators
- Operates a Strategy Arena where 4 AI strategies (EMA Breakout, RSI Extremes, RSI Reversion, VWAP Reversion) compete head-to-head with live P&L tracking
- Proxies web search through Brave Search and Tavily with result deduplication and fusion
- Executes Python and JavaScript code in sandboxed E2B environments (60s timeout)
