FIX Trading Community Launches Industry Framework for 24-Hour Global Markets

The FIX Trading Community has released a 24-Hour Markets Industry FAQ to standardise how firms handle the shift toward around-the-clock trading. For fintech professionals, this provides a critical framework for managing trade dates, connectivity, and post-trade workflows as exchanges move beyond traditional sessions, ensuring operational resilience and preventing fragmented data conventions across global venues.

What was announced

The publication serves as a practical guide for firms navigating extended-hours and 24-hour trading sessions. Developed by industry practitioners, the FAQ addresses technical and operational challenges across the entire trade lifecycle. Key focus areas include guidance on trading sessions, sub-session flagging, and the complexities of trade date considerations when a session spans multiple calendar days. The document also provides clarity on order management, post-trade processing, clearing implications, and maintaining operational resilience in a non-stop environment.

A central component of the guide is the demonstration of how existing FIX data fields can be utilised to support these models. By leveraging established standards, the FIX Trading Community aims to promote industry-wide consistency, preventing individual trading venues from developing proprietary, incompatible conventions for 24-hour activity. The FAQ is currently available via the FIX Trading Community website and targets market participants including exchanges, trading venues, and investment firms currently exploring or implementing longer trading hours.

The companies involved

The FIX Trading Community is a non-profit, industry-driven body responsible for the Financial Information eXchange (FIX) protocol, the messaging standard that underpins much of the world's electronic trading. It functions as a collaborative environment where buy-side and sell-side firms, alongside vendors and exchanges, develop standards to improve global market efficiency and reduce costs. The organisation has a significant footprint in the market, with its protocols used for everything from pre-trade indications to post-trade reporting.

In this specific initiative, the work was led by the 24-Hour Markets Working Group, featuring leadership from CalcGuard Technologies and Aquis Technologies. CalcGuard Technologies, where Enrico Cacciatore serves as Co-Founder and Chief Product & Strategy Officer, focuses on product and strategy within the trading technology space. Aquis Technologies, represented by John Greenan, Head, Technologies, is a division of Aquis Exchange PLC, providing software and technology services to the financial markets. Together, these entities represent the cross-industry collaboration required to maintain interoperability as market structures evolve toward continuous operation.

What FF News has reported before

FF News has tracked the FIX Trading Community’s ongoing efforts to standardise complex market operations. In late 2026, the organisation was active in regulatory discussions, as seen when the FIX Trading Community Calls for Greater Transparency and Resilience in UK Equities Reform. The group has also focused heavily on post-trade efficiency, recently releasing a FIX Trading Community Launches New Standardised Margin Reporting Framework for Asset Managers and subsequent FIX Publishes Guidance for Asset Manager & Broker Margin Reporting. Furthermore, the community has explored the intersection of traditional and digital finance, collaborating on a report titled GDF, FIX, and Deloitte Call for Interoperability Standards in New Digital Market Infrastructure Report.

What this means

The move toward 24-hour trading is no longer a niche retail trend but a structural shift that threatens to break legacy reconciliation systems. By formalising these FAQs, FIX is attempting to head off a "Wild West" scenario where every exchange implements its own timestamping and session logic. The real pressure now falls on legacy core banking and back-office providers, many of whom still rely on end-of-day batch processing. If the industry cannot agree on how to handle "trade date" when the sun never sets, the resulting fragmentation will lead to a surge in settlement failures and operational risk.
