Markets move in microseconds. The layer underneath has to keep pace on every order — so delivery, execution, and risk run as one path that doesn’t fall behind.
A complete backend for products that trade.
Four subsystemsOne path, from feed to journal.
Every order takes the same ordered, reproducible route through the layer.
Normalized feeds fan out over a low-latency streaming core.
Orders follow a single reproducible execution path.
Guardrails evaluate before anything reaches the book.
Every action is logged, ordered, and replayable.
One integration, every asset class.
Six markets · one interfaceConnect in an afternoon.
One session, one stream, one route call. The shape stays stable across every market — integrate once, not per asset class.
Built the way trading infrastructure should be.
Deterministic by design. Every action is ordered, journaled, and reproducible.
Engineered for low, predictable delivery — not just a good average.
Risk is evaluated inline. When a limit is reached, the safe action is the default.
We build the layer other trading platforms are built on.
ArcDX is a small, senior team focused on one thing — making real-time trading infrastructure that’s correct, fast, and quietly dependable, so the products on top of it never have to think about it.
