Systematic edge, repeatable process.
A quantitative trading platform for systematic event and equity strategies. Research, execution, and risk in one operating surface, built for desks that measure everything.
Overview
QUANTITATIVE FINANCESigma Axion markets the engineering discipline, not the trading: uncorrelated systematic strategies operated under layered risk controls, low-impact execution with strict pre-trade checks, and an append-only audit log that records every cap, every breach, and every override. Process over prediction. Survival first.
Layered risk
Hard limits, per-strategy caps, operator overrides, and a kill switch. No order fires without a live risk greenlight.
Process over prediction
Every decision is logged with its pre-trade assumptions and post-trade reality, so the process keeps improving.
Survival first
Fractional-Kelly sizing and hard daily stops. Drawdown is capped before upside is chased.
Transparent by design
An append-only log records every state-changing action with actor and reason. Limits are tunable; history is not.
Capabilities
What the platform doesHigh-fidelity data, honest math.
Normalized feeds from regulated venues, time-stamped at ingest with microstructure preserved for replay and backtest parity. Fees, slippage, and fill probability are modeled before the first dollar moves.
Four layers between an idea and an order.
Hard limits, soft limits, strategy-level caps, and operator control, with daily reconciliation of position, cash, and P&L. The risk engine is never overridden mid-session.
Low-impact, low-variance, fully audited.
Liquidity-weighted sizing and strict pre-trade checks under an agent approval layer, with paper-first promotion gates before anything trades live. Every event lands in the append-only audit log.
