Engineered for systematic trading
Our REST API covers account management, order placement and market data. For latency-sensitive strategies, FIX 4.4 connectivity is available on request and co-located in the Equinix LD5 data centre alongside our matching engine — the same path every Moneywell order takes.
Stable, versioned, documented
We version every public endpoint, maintain a deprecation schedule, and publish an OpenAPI specification. Breaking changes are announced months in advance with parallel old/new endpoints during the transition.
