◇ Bolsa

Bolsa is a phosphor-green CRT terminal for paper trading stocks and ETFs against Alpaca's paper account. Watchlists, candlestick and line charts across nine timeframes, market and limit orders, live quotes, portfolio P&L, and a full trade log. Keyboard-first, no chrome, no real money on the line. The twist is the MCP server: every tool the UI exposes is also wired up for Claude (or any MCP-aware agent) to drive directly. Start a named session, watch the agent log its reasoning in real time over Supabase realtime, place orders, run backtests on historical bars. The human spectates through the same view, and can hit STOP at any moment.
