The platform

Built for the discipline of systematic trading.

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.

Backtesting

Replay nine years of market data at daily or intraday resolution. Walk-forward validation, regime analysis, drawdown decomposition.

Live execution

Interactive Brokers integration with order management, partial-fill handling, and broker statement reconciliation.

Data management

Three-stream futures architecture, NYSE holiday-aware candle resampling, point-in-time data integrity.

Risk controls

Per-strategy capital allocation, drawdown limits, kill switches. Risk state persists across restarts.

Parity reconciliation

Every trading day, the live engine reconciles against the backtest. Decisions, executions, slippage, positions, equity.

$

Fund infrastructure

Unit-based NAV accounting, investor registry, fee engine with per-investor high-water marks. Cyprus RAIF-ready.

How it works

From hypothesis to live capital in three movements.

01 · Research

Express your edge as code.

Compose strategies from a vocabulary of momentum, rotation, mean-reversion, and snap-and-hold primitives. Validate against the full historical window.

02 · Validate

Stress the strategy before it runs.

Staggered rebalancing tests, slippage sensitivity, out-of-sample windows, regime breakdowns. If the edge isn't structural, you'll see it here.

03 · Execute

Deploy and reconcile.

Production strategies trade through Interactive Brokers. Daily parity checks confirm the live engine matches the backtest within tolerance.

Principles

What we will not compromise.

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.

P · 01

The backtest must be honest.

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.

P · 02

Live must equal backtest.

Every trading day, automated reconciliation compares live decisions, fills, slippage, positions, and equity against what the backtest would have produced.

P · 03

Capital has memory.

Per-strategy high-water marks, drawdown caps, and kill switches persist across restarts. A crashed process never erases what it owes.

P · 04

Humans stay in the loop.

The system asks for confirmation on capital-allocation changes, manual position closes, and any action with irreversible blast radius.

The third AI/ON is by invitation.

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.
