3aion is a systematic algorithmic trading platform for quantitative investors. Build strategies, validate them against years of data, execute with institutional discipline.
Six tools that work as one system. Research a strategy, validate it, deploy it, and watch the live engine match the backtest bar-by-bar.
Replay nine years of market data at daily or intraday resolution. Walk-forward validation, regime analysis, drawdown decomposition.
Interactive Brokers integration with order management, partial-fill handling, and broker statement reconciliation.
Three-stream futures architecture, NYSE holiday-aware candle resampling, point-in-time data integrity.
Per-strategy capital allocation, drawdown limits, kill switches. Risk state persists across restarts.
Every trading day, the live engine reconciles against the backtest. Decisions, executions, slippage, positions, equity.
Unit-based NAV accounting, investor registry, fee engine with per-investor high-water marks. Cyprus RAIF-ready.
Compose strategies from a vocabulary of momentum, rotation, mean-reversion, and snap-and-hold primitives. Validate against the full historical window.
Staggered rebalancing tests, slippage sensitivity, out-of-sample windows, regime breakdowns. If the edge isn't structural, you'll see it here.
Production strategies trade through Interactive Brokers. Daily parity checks confirm the live engine matches the backtest within tolerance.
Trading systems fail in known ways. We build to remove the failures we can engineer away — so the only risk left is the one you actually intended to take.
No look-ahead bias. No implicit overfitting. Out-of-sample windows are reported as out-of-sample. If the strategy looks too good, the implementation is the first suspect.
Every trading day, automated reconciliation compares live decisions, fills, slippage, positions, and equity against what the backtest would have produced.
Per-strategy high-water marks, drawdown caps, and kill switches persist across restarts. A crashed process never erases what it owes.
The system asks for confirmation on capital-allocation changes, manual position closes, and any action with irreversible blast radius.
We are working with a small group of allocators, family offices, and quantitative investors during the closed beta. If your work is serious, we want to hear from you.
