The OnixS ultra low latency C++ FIX Engine is a high speed implementation of the FIX Protocol in C++ FIX Engine to provide superior performance for mission-critical trading software systems.

Main features include:

• Ultra low latency performance for Direct Market Access (DMA), High Frequency Trading (HFT) and Algorithmic Trading applications.
• Easy-to-use and flexible API
• Comprehensive documentation
• Venue-specific quick-start samples
• FAST 1.1 and FAST 1.2 decoding and encoding (pre-certified with CME and ICAP, fully compatible with Eurex EBS, NYSE Liffe XDP, NGM, etc.)
• Supplied as a C++ dynamic library (DLL)
• SSL encryption
• Supports multiple FIX Protocol versions simultaneously
• Supports multiple FIX sessions simultaneously
• Support all current FIX Protocol versions (4.0, 4.1, 4.2, 4.3, 4.4, 5.0, 5.0 SP1, 5.0 SP2, FIXML)
• Supports all tag and message types of each FIX Protocol version (equities, fixed income, derivatives, FX etc)
• Flexible support for user-defined tags and user-defined message types
• Supports FIX Dialects (venue-specific interpretations of the FIX Protocol) on a per-session bases
• Configurable validation of required fields
• Persistence (the ability to log data to a flat file and restore the state after fail-over)
• Session scheduler
• High-availability
• Versatile diagnostic

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
• The Adaptive Communication Environment (ACE) object-oriented framework is used to implement core patterns for concurrent communication software.
• 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.
