Further information

The OnixS high speed C++ FIX Engine provides the following services:

  • Manages network connections
  • Performs SSL encryption and decryption
  • Manages the session layer of the FIX Protocol
  • Creates (outgoing) messages
  • Parses (incoming) messages
  • Validates messages
  • Persists messages
  • Session recovery

Onix Solutions' Next Generation FIX Engine is based on the latest achievements of Software Engineering:

  • Advanced threading architecture
  • Parsing, validation and assembling of FIX messages is extremely flexible, since it dynamically uses information provided in FIX XML Specifications, thus end-user may easily tune the FIX Parser for any FIX Dialect.
  • Design Patterns are used extensively to provide elegant, efficient and reusable solutions.
