What makes the sandbox credible
🦀 Same Rust engine as production
The PaperTradingEngine is the same orchestrator we ship for live HFT — Almgren-Chriss optimal execution, MFG impact model, HJB scheduling. No mocks.
⚙️ Knobs visible by default
Slippage (bps), latency (ms), max capital, order book depth — researchers see all parameters from the Researcher tier upward. No hidden defaults.
📓 Fork as Jupyter notebook
One click writes a reproducible notebook with your broker, knobs and last symbol pre-wired. Your sweeps stay yours.
📡 EventBus + gamification
Every paper fill emits trading.paper.fill on the internal EventBus. Your first fill unlocks the paper_trade_first_fill achievement.
🔒 Public-only data wall
A CI scanner enforces that no private module, no calibrated WP6 content, no _changes/sessions stream is ever surfaced on the LMS. Audit it on GitHub.
🧪 Bring your own broker
BrokerInterface is an ABC. Implement search_symbols / get_quote / submit_paper_order and your venue plugs in.
