FIX Engine — FIX Antenna C++
FIX Antenna® C++ is specifically designed to deliver high
performance. It can deliver over 60,000 messages per second on a
single CPU and has been benchmarked at 30,000 messages per second
across 200 sessions. This level of performance means it is an ideal
solution for exchanges, sell sides and program trading operations.
FIX Antenna C++ FIX engine is currently deployed in some of the
most demanding environments in the world.
FIX Antenna C++ FIX engine is not purely a performance engine.
It has a rich feature set to support the variety of requirements
that a FIX engine must fulfill. It supports FIX 4.0, 4.1, 4.2, 4.3,
4.4, 5.0, 5.0 SP1, 5.0 SP2 and FAST. Furthermore, it comes with a
rich UI for monitoring
session statuses and parameters in real time.
All libraries/servers are pre-configured for and certified with
multiple exchanges, including CME, ICE, INET and many
Our products come with a 24x7 support provided worldwide and
availability of "on demand" software escrow.

|High throughput / low latency
The highest performing FIX engine in existence.
Delivers over 60,000 messages per second.
Benchmarked at 30,000 messages per second
across 200 sessions.
Adds up to 16 microseconds' latency on 100 Mbps
network with persistence and 6 microseconds'
latency on 100 Mbps network without persistence.
Allows configuring sending/receiving prioritization for
In transient mode it can deliver over 115,000
messages per second. Please refer to the latest benchmarks of FIX
Antenna C++, Windows- and Linux-based.
|Supports standard FIX
- 100% FIX standard compliance:
- FIX 4.0, 4.1, 4.2, 4.3, 4.4, 5.0, 5.0 SP1, 5.0 SP2
- FAST 1.1
- Supports all FIX message types (pre-trade, trade, post-trade,
market data, etc.)
- Message validation (well-formedness, required and conditionally
required fields, fields order, types, etc.)
- Customizable FIX protocol with user-defined tags and message
types. Create your own FIX dialect e.g. defined extra field for a
message, change "required" attribute, etc. in a friendly XML
- Multiple session management
- Supports up to 200 concurrent sessions on a single instance on
recommended hardware. Number of concurrent sessions can be
increased if more CPUs are added
- Each session can be configured separately. FIX Dialect can be
configured for session
- Guaranteed delivery
- Relies on the store and forward technique
- Flat files are used for persistence to achieve maximum
- Standard FIX routing based on DeliverTo and OnBehalfOf
- Later delivery mode allows unsent messages to be stored in
queue and delivered later when connection is re-established.
Recommended configuration for a session, where execution reports
are to be delivered e.g. session with traders
- Rejecting mode allows messages, which cannot be sent during
some reasonable time (customizable), to be rejected. Recommended
configuration for a session, where orders are to be delivered e.g.
session with exchanges
|Highly customizable FIX session level
- Different modes of handling sequence number during logon and
- Intraday logout tolerance
- Custom logon message
- Force sequence number reset on logon
- Standard FIX authorization utilizing username and password
fields in FIX Logon message
- FIX encryption to work in non-private networks: DES and
- SSL tunneling
- Auto-accept incoming sessions (to simplify development and
testing) and auto-decline non pre-configured sessions
|Reliability vs. performance
- Supports transient sessions, which do not use any persistence.
This significantly increases performance giving up recovery.
Applicable when recovery is not required (e.g. for market data) or
when persistence is done by the application, which uses the FIX
- Ability to enable or disable Nagle's algorithm to minimize
latency or maximize throughput
- Ability to configure (or turn off) the number of messages to be
joined in a bunch before sending
- Ability to dedicate threads for session for sending and
receiving data, to minimize overhead on context switching
|Monitoring and administration
- Built-in remote monitoring and administrative interface for
sessions monitoring and management
- Utilizing FIX session and the same FIX listen port for
- Friendly XML-based DSL for administrative instructions: easy to
read, easy to extend
- Public API to override and/or extend existing administrative
- Rich monitoring and
administration GUI out of the box
|Message composition API
- Provides the following functionality:
- Creating a message singleton by FIX protocol version and
- Creating a message from a raw FIX string (parse)
- Serializing a FIX object message to raw FIX string
- Adding, removing, modifying FIX fields and repeating
- Validating message
- FIX flat message model - generic model to work with the
abstract FIXMessage class via fields and groups getters and
setters, which gives the highest performance
- FIX object model - each FIX message type is a class with FIX
fields as members, using intelligence to make working with FIX
business object more pleasant
- User-friendly intuitive pure ANSI C++ public interface
- Is supplied as a dynamic library (.dll) for Windows or a shared
object dynamic library(.so) for Linux
The package includes:
FIX engine is built using real time design patterns proven over
10 years of practice.
The transport layer is implemented based on
Boost.Asio, Myricom DBL.
The design of FIX Antenna C++ allows supporting various modes to
maximize high throughput, to achieve low latency, or to operate in
a custom mode with balanced throughput and latency. The internal
design allows also to control a number of threads by fixing this
number in case of multiple FIX sessions to share time between them
or by dedicating threads for individual FIX sessions (2 threads per
Access to low level parameters is provided to tune TCP/IP
performance (Nagel's algorithm), choose the type of storage for the
state recovery, collect run time statistics, measure time taken by
a particular operation, as well as turn on and turn off a
particular feature, and many others.
FIX Antenna C++ is a library written in Ansi C++. It is a full
implementation of FIX protocol. It provides the following main APIs
for trading applications to:
- Create multiple FIX sessions (initiators and acceptors)
- Open and close FIX session
- Form FIX and FIXML message
- Parse FIX and FIXML message
- Validate FIX message
- Send and receive FIX messages
- Set sequence numbers
- Encrypt FIX messages
