What is FIX?
The Financial Information eXchange ("FIX") Protocol is a series of messaging specifications for the electronic communication of trade-related messages. It has been developed through the collaboration of banks, broker-dealers, exchanges, industry utilities and associations, institutional investors, and information technology providers from around the world. These market participants share a vision of a common, global language for the automated trading of financial instruments.
FIX is the industry-driven messaging standard that is changing the face of the global financial services sector, as firms use the protocol to transact in an electronic, transparent, cost efficient and timely manner. FIX is open and free, but it is not software. Rather, FIX is a specification around which software developers can create commercial or open-source software, as they see fit. As the market's leading trade-communications protocol, FIX is integral to many order management and trading systems. Yet, its power is unobtrusive, as users of these systems can benefit from FIX without knowing the language itself.
Since its inception in 1992 as a bilateral communications framework for equity trading between Fidelity Investments and Salomon Brothers, FIX has become the de-facto messaging standard for pre-trade and trade communication globally within the Equity markets, and is now experiencing rapid expansion into the post-trade space, supporting Straight -Through- Processing (STP) from Indication-of-Interest (IOI) to Allocations and Confirmations. From this foundation, the protocol is gathering increased momentum, as it continues to expand across the Foreign Exchange, Fixed Income and Derivative markets.
The significant adoption of FIX within the financial services community was empirically highlighted by the FIX Global Survey which was conducted by TowerGroup in 2005. The results cited that 75% of buy-side and 80% of sell-side firms interviewed currently use FIX for electronic trading, and that both groups plan to focus substantial efforts on expanding their FIX usage to over 93%, as well as leveraging FIX across additional asset classes by 2008. The survey also revealed that FIX is developing a key role within the post trade space, as over 80% of buy-side firms, and over 95% of sell-side firms surveyed currently support, or plan to support FIX for allocations.
Further to this, FIX is gaining increased attention within the exchanges community as over three quarters of all exchanges surveyed supported a FIX interface, with the majority handling over 25% of their total trading volume via FIX.
The success of the FIX Protocol is primarily due to the voluntary efforts of its member firms from the buy-side, sell-side, vendor and exchange communities who work together to help achieve the FIX Protocol Limited (FPL) mission statement, "To improve the global trading process by defining, managing and promoting an open protocol for real-time, electronic communication between industry participants, while complementing industry standards."
Technical and business professionals from the FPL member firms coordinate their activities and organize their work through a series of committees, subcommittees, and working groups, all overseen by a Global Steering Committee that aims to ensure consistency of protocol application as it is extended into new markets, asset classes, and phases of the trade lifecycle. In addition to rigorous engineering and technical efforts undertaken to ensure the ongoing applicability of the protocol to financial-market systems, the FIX Protocol benefits from an energetic educational and marketing effort that seeks to keep the specification viable, relevant, and responsive to the needs of market participants.
No one knows with certainty how many people use FIX or how much of the global volume of securities transactions is effected via the FIX Protocol. What is certain is that virtually every major stock exchange and investment bank uses FIX for electronic trading, as do the world's largest mutual funds and money managers and thousands of smaller investment firms. Leading futures exchanges offer FIX connections and major bond dealers either have or are implementing them.
Both "adopters" - users of the FIX Protocol - and vendors of FIX-related technologies use the FPL website to inform the marketplace of their FIX capabilities and capacities. If you want to know whether your counterparties offer FIX communications capabilities, just ask them. If you want to learn more about FIX or how to implement FIX connectivity for your business, send a message to a member of FPL's Global Education & Marketing Committee, or to the .
While the FIX specification is open and free, implementing FIX requires planning, software, and network services, if not other goods and services. For some organizations, obtaining and maintaining productive FIX connectivity can be a relatively inexpensive process, measured in a few thousand dollars of start-up expenses and a few hundred dollars of recurring charges. At the opposite end of the spectrum, creating a large-scale, continuously-operating FIX network serving tens of thousands of users can easily be a multi-million-dollar proposition. The best place to start your due diligence is the FIX Implementation Guide. Dozens of top FIX experts have volunteered their time to create a guide that is useful at the business and technical level. Investing even an hour reviewing the guide will help you understand the type of planning and resources required to implement FIX in a way that helps your business.
