Our matching engine has operated in production at regulated exchanges since 2016, processing continuous trading sessions across equities, futures, and digital asset markets without interruption. A decade of live operation has established it as a stable, deterministic core for markets that cannot tolerate downtime, latency jitter, or unpredictable execution.
The matching engine's core is implemented in C++ for deterministic, allocation-free execution on the hot path. It has since been re-engineered on Aeron — a C++ messaging framework — transported over a single UDP multicast channel and engineered to keep messaging latency under 10 microseconds. It runs on an in-house active-active architecture in which every matching node remains live and synchronized rather than held in passive standby, eliminating failover gaps and delivering genuine zero-downtime resilience. All nodes share a single, globally synchronized clock aligned to industry trading-infrastructure timing standards, ensuring every matched order carries consistent, audit-ready timestamp precision across venues.
