FIX

FIX, or Financial Information eXchange, is a standardized digital communication protocol used primarily by financial institutions to securely and efficiently transmit trading information and instructions in real-time. It enables different banks, brokers, and traders to exchange important data—like buy and sell orders, confirmations, and updates—using a common language. This standardization reduces errors, speeds up transactions, and improves collaboration across the financial industry. Essentially, FIX acts as a universal language that ensures everyone involved in a trade understands and processes information consistently and accurately.
