What is OpenTraderWorld?

GitHub

🔒

Self-hosted & private

Runs on your computer or server with Docker. Localhost-only by default; you decide if and how it is reachable. No account, no cloud, no telemetry.

🧩

Modular

20+ modules — install only what you use. Trading Journal, historical data, backtester, quant tools, portfolio tracker, news aggregator, notes and more.

📈

Built for traders

Weighted-average-cost PnL, fee schedules, multi-currency with automatic FX, scaling in/out, SL/TP brackets, 13F holdings, tax estimates.

🤖

With AI Agent & MCP

A built-in AI chat assistant (bring your own provider) that can act on your data, plus an MCP server so external agents read or update your modules through a controlled, token-scoped gateway — off by default.
