FIX Online Specification (as of EP97)
This is the starting page for the specification of the application layer of the FIX Protocol. It provides the normative specification and is the successor of the previous specification documents “FIX Version 5.0 Service Pack 2 Specification with 20110818 Errata” (aka “Volume 1-7”). The previous specification documents also contained FIX Technical Standards (FIX tagvalue, FIXML) as well as various guideline material that is not considered to be part of the normative specification.
