What is "quickfix"

QuickFIX is an open source ( BSD licensed) FIX messaging engine written in C++. It is cross-platform and runs on Windows, Mac OS X, Linux, Solaris, and FreeBSD. Several implementation variants of the engine exist, including

• QuickFIX/J, a Java open source (also BSD licensed) implementation of the engine.
• QuickFIX/n, a C# open source (also BSD licensed) implementation of the engine.
• QuickFIX/Go, a Go open source (also BSD licensed) implementation of the engine.

The developers also offer QuickFIX Log Viewer, designed to parse FIX messages out of a given file, even if there are other messages within, making it flexible and usable on more general log files. Commercial support for the QuickFIX engine is available from third parties.
