The OnixS ultra low latency .NET FIX Engine is a high performance implementat of the FIX Protocol that FIX-enables .NET applications (C#, VB.NET, Managed C++, F#, etc.) in a simple, reliable and cost effective manner.

Main features include:

• Easy-to-use API
• Native .NET conventions and idioms (properties, events, delegates, etc)
• Ultra low latency performance for Direct Market Access (DMA), High Frequency Trading (HFT) and Algorithmic Trading applications
• Comprehensive documentation
• Quick start venue-specific samples in C# and VB.NET
• FIX Engine is supplied as a .NET class library (assembly) that offers complete flexibility over the implementation
• FAST 1.1 and FAST 1.2 encoding and decoding (pre-certified with CME and ICAP, fully compatible with Eurex EBS, NYSE Liffe XDP, NGM, etc.)
• Session Scheduler
• 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)
• High-availability
• Versatile diagnostics

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

• manages network connections
• manages the session layer of the FIX Protocol
• recovers sessions state in accordance with the FIX Session state matrix
• creates (outgoing) messages
• parses (incoming) messages
• validates messages
• session recovery

OnixS Next Generation .NET 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 the FIX Dialect description, thus end-user may easily tune the FIX Parser for any FIX Venue.
• Design Patterns are used extensively to provide elegant, efficient and reusable solutions.
