• 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)
