04 — Reference

Frequently asked.

FIX (Financial Information Exchange) is the industry-standard protocol for real-time electronic exchange of securities transactions. It provides a deterministic, low-latency channel between a counterparty's trading systems and a liquidity venue.

Counterparties open three sessions over TLS — order entry, market data, and drop copy. Each session is identified by a SenderCompID/TargetCompID pair issued at onboarding. Heartbeats run at 30 seconds, with sequence-numbered recovery on reconnect.

Brokers, hedge funds, proprietary trading firms, and treasury desks that operate their own execution stack and require deterministic latency, drop-copy auditing, or programmatic order management.

Median tick-to-trade through the core is approximately 20 ms when measured from a counterparty co-located in Equinix LD4. End-to-end latency depends on the counterparty's connectivity choice — cross-connect, VPN, or public transport.

Counterparties send a MarketDataRequest specifying symbols and depth. Subscriptions stream incremental updates; one-shot snapshots are also supported. Top-of-book and full depth-of-book are available per counterparty configuration.

Market, Limit, Stop, Stop-Limit, IOC, FOK, GTC, and GTD. Order entry uses NewOrderSingle (D), with OrderCancelRequest (F) and OrderCancelReplaceRequest (G) for amendments. OrderStatusRequest (H) and OrderMassStatusRequest (AF) provide synchronous state recovery.
