Open-source engine
Rio is the desktop terminal for the open-source MCT engine. If you can write an Excel-style formula, you can define trading logic — the engine gives you real-time market data, balances and indicators right in your configuration.
Core features
An interactive multi-agent assistant with specialized subgraphs for configuration tuning, on-demand backtesting, trading performance analytics, and a proactive Trading Oracle that watches your strategies.
Define position sizing and custom strategy logic with familiar spreadsheet-style formulas. Real-time market data, balances and technical indicators are available directly in your configuration.
dynamic_quantity: "max(min_qty, (balance * 0.02) / close)"
Flexible multi-strategy quorum voting. Run a single strategy 1-of-1, two independent triggers 1-of-2, or strict 2-of-2 consensus before any order is placed.
consensus: buy: 1.3 sell: 0.5
Multi-asset simulation with independent clocks per asset, realistic execution frictions — slippage, latency and fees — drift detection, and tick-by-tick replay of recorded sessions.
A FastAPI server exposing order analytics, monthly heatmaps, latency metrics and configuration proposals, plus live log streaming over WebSocket at /api/v1/logs/ws.
Built-in collectors for CPU and memory usage, WebSocket health, order lifecycle timings and exchange telemetry — so delays and failures are always explainable.
Git-like history tracking, a full audit trail and one-command rollback for every runtime configuration change.
Run modes
make run-simulatedPaper trading against live market streams with simulated in-memory orders.
make run-backtestReplay historical CSV or recorded audit data with configurable slippage, latency and fees.
make run-liveExecute real orders on the configured exchange, with the API and agent server attached.
make run-headlessCore engine only — trading operations without the HTTP/WebSocket server.
