FIX (Financial Information eXchange) is a messaging standard used by financial institutions to communicate trading information electronically. Developed in 1992 by Salomon Brothers and Fidelity Investments, FIX has become the dominant protocol for order routing, execution reporting, and market data distribution across equities, fixed income, derivatives, and foreign exchange markets.
For brokers, FIX is how you connect to institutional liquidity providers, exchanges, and professional clients. Understanding FIX is essential for anyone operating or evaluating multi-asset trading infrastructure.
