It plays a crucial role in facilitating communication between financial institutions, enabling them to execute trades efficiently and securely. This article explores the fundamentals of FIX trading, its importance, and how it operates in the ever-evolving landscape of financial markets.

The Basics of FIX Trading:

FIX trading is a protocol that standardizes the format and content of messages exchanged between financial institutions involved in trading activities.
