FAQ

FIX (Financial Information eXchange) is an open, global standard electronic communications protocol used for real-time exchange of trade-related messages between financial institutions. It defines message formats for pre-trade, trade, and post-trade activities such as order routing, execution reporting, market data, and allocation. FIX is widely adopted across buy-side and sell-side firms to facilitate seamless, reliable, and low-latency trading communication. Follow our blog to learn more about FIX messaging and how it powers today's trading infrastructure.

A FIX Engine is a software implementation that handles the complexities of the FIX protocol, including message construction, parsing, session management, sequence number tracking, logon/logout processes, and error recovery. It acts as the communication backbone, allowing trading applications to send and receive FIX messages without requiring developers to build low-level protocol handling from scratch. Essentially, a FIX engine manages the entire lifecycle of FIX sessions, ensuring reliable and compliant message exchange.
