QuickFIX is a free, open-source implementation of the FIX protocol (Financial Information eXchange). It is a full-featured messaging engine that supports FIX versions 4.0 through 5.0 SP2, including FIXT 1.1.

• FIX Protocol Support: FIX 4.0, 4.1, 4.2, 4.3, 4.4, 5.0, 5.0 SP1, 5.0 SP2, and FIXT 1.1
• Multiple Language Bindings: C++, Python, Ruby (via SWIG)
• Database Support: MySQL, PostgreSQL, ODBC
• SSL/TLS Support: Native OpenSSL integration
• Flexible Architecture: Pluggable message stores and logging
• Cross-Platform: Windows, Linux, macOS
• Production Ready: Used by banks, brokers, and trading firms worldwide

QuickFIX is tested on:

• Windows: Windows Server 2019, Windows Server 2022
• Linux: Ubuntu (latest), various distributions
• macOS: Latest versions

• C++17 compatible compiler (GCC, Clang, MSVC)
• CMake 3.5+ or Autotools
• Optional: OpenSSL (for SSL/TLS support)
• Optional: MySQL, PostgreSQL, or ODBC (for database message stores)

• Examples: See the examples/ directory for sample applications

QuickFIX includes several example applications:

• executor: A simple order execution simulator
• ordermatch: A matching engine example
• tradeclient: An interactive trading client

These examples demonstrate how to build FIX applications using QuickFIX.

# Build with Python 3 support
cmake -DHAVE_PYTHON3=ON .
make

Python bindings are also available via pip:

pip install quickfix

# Build with Ruby support using autotools
./configure --with-ruby
make

Run the test suite:

# With CMake
cmake --build . --target test

# With Autotools
make check
