Algorithmic trading, fully observable.
Trading platforms ship in fragments. This one ships whole — sim, paper, and live execution on the same code path, with risk gates, multi-broker support, and an audit trail you can grep.
Currently invite-only. Email us to join the alpha.
Built for traders at
Every layer, instrumented.
The same primitives a prop desk uses — risk engine, execution router, audit log — wired up for retail and dev workflows.
Sim → paper → live
One strategy entrypoint, three modes. Promote without code changes. Replay diffs catch drift between modes before it costs you.
Risk gates and kill switch
Per-order, daily-loss, and concentration limits enforced before any broker sees an order. Halt-all flattens positions in under a second in sim.
Five-broker execution
Alpaca, IBKR, Binance, Coinbase, OANDA — one router, idempotent client IDs, reconciliation across reconnects.
Real-time data plane
Polygon, Alpaca, Binance, OANDA WebSockets multiplexed onto an async bus. Tick-level Parquet history, gap detection, auto-reconnect.
Strategy library
Trend, mean reversion, breakout, market making, options spreads, funding-rate arb. Backtest, walk-forward, Monte Carlo built in.
Full audit trail
Every order, every fill, every risk decision logged to Supabase with the reasoning that triggered it. Click any trade, see why.
LLM-narrated decisions
Bot Passport surfaces decisions, lineage, and risk posture in plain English. Audit a strategy without reading code.
Paper trading on real data
Live market feeds, simulated capital. Identical orderbook semantics to live mode. The last step before real money.
Bot marketplace
Publish strategies with provenance, subscribers fork or run as-is. Performance, drawdown, and trade history are public by default.
Three steps. Real money is the last one.
Sign up
Email or Google. Sim mode opens immediately — no broker connection required to ship your first backtest.
Connect a broker
Alpaca, IBKR, Binance, Coinbase, or OANDA. Paper accounts work end-to-end. Live activation is a separate, audited gate.
Deploy a strategy
Pick one from the library or upload yours. Backtest, paper, then promote to live with measurable parity.
