FIX 5.0 Specification Service Pack 1, Second Draft

FIX 5.0 Service Pack 1 includes 25 Extension Packs, each of which enhances the current functionality delivered by FIX 5.0.

• Improved functionality for exchange quotation models and order routing practices
• Enhanced Listed Derivatives reference data support for Options, Futures, and Options on Futures
• New set of messages for Market Structure definition
• Support for trading listed Interest Rate Swaps
• Application level sequencing with advanced support for market data recovery
• Foreign Exchange OTC settlement obligations
• Improved integration between FIX, FIXML and FpML
• Changes to Rule80A, OrderCapacity, and Order Restrictions to reflect revised NYSE regulations

The FPL Global Technical Committee welcomes industry comments and feedback on FIX 5.0 Service Pack 1. Once all feedback has been compiled and implemented a second release candidate will be made available for comment before the final release in March. All feedback for the second release should be posted to a dedicated discussion forum http://www.fixprotocol.org/discuss/55

The comment period is now open and will run for two weeks concluding Friday, March 7th.
