B2BITS provides an integrated suite of FIX connectivity solutions designed for low-latency, mission-critical trading infrastructures — from ultra-fast FIX engine libraries to a full FIX application server that delivers intelligent FIX message transformation, routing and scalable connectivity for all types of market participants.
FIX Antenna FIX Engines
B2BITS’ FIX Antenna suite (C++, Java, .NET, Python) is a set of industry-grade FIX engine libraries optimized for ultra-low latency, high throughput and broad protocol support. These engines can be embedded into your trading systems, middle-ware or gateway components to provide FIX connectivity in the most demanding environments.
Core capabilities:
- Support for all FIX versions from 4.0 to the latest and FAST 1.1
- Handles high message rates with consistent performance
- Rich UI monitoring for live session and performance stats
- Available across major platforms (Windows, Linux)
These are library-based FIX engines you link into your own applications where you need lightweight, embeddable FIX connectivity.
FIXEdge — Full FIX Server & Application Layer
In addition to engine libraries, B2BITS offers FIXEdge, a stand-alone FIX server and application platform that elevates FIX connectivity from protocol handling to full business logic, routing and enterprise-ready message flows for trading operations.
FIXEdge can be deployed as:
- A FIX server that accepts and initiates FIX sessions
- A message routing and transformation hub
- A gateway/router for exchanges, brokers, buy-side firms, clearing houses or digital assets platforms
- A central FIX service layer in enterprise trading stacks
Message Transformation & Routing
FIXEdge delivers advanced message handling capabilities that go far beyond simple FIX session management:
- Powerful rule engine for message transformation, enrichment and business logic
- Convert between multiple FIX versions, JSON and FIX ↔ FIXML
- Normalize and route messages intelligently based on content and business rules
- Support for custom scripting (Javascript, XSLT, Python,Groovy) and plug-ins
- Integrations with databases and external transports (IBM MQ, Kafka, REST, JMS)
This makes FIXEdge ideal for use as a central message hub in complex trading ecosystems, ensuring consistent, automated handling of FIX traffic between counterparties, internal systems and market venues.
High Availability & Flexible Deployment
FIXEdge is designed for enterprise-grade resilience and scalability:
- Supports clustered deployments with automatic failover and state replication
- Can be deployed on-premises, in private data centers, or in the cloud
- Kubernetes-based deployments with Helm charts for simplified management
- Disaster recovery features with real-time log replication
- Fast recovery after node failures to minimize service disruption
These capabilities allow FIXEdge to serve as a central FIX engine with uninterrupted service even under heavy load or infrastructure failures.
Use Cases & Market Roles
FIXEdge isn’t just a connectivity library — it’s a full FIX engine platform that can play key roles in:
- Exchange gateways and market-access engines
- Broker-dealer FIX routers and smart order handlers
- Buy-side order entry and execution management systems
- Clearing and settlement interfaces
- Digital assets trading platforms
- Cross-venue trading and message normalization hubs
Whether you need a high-throughput engine embedded in your application, or a full server handling business logic, transformations and multilateral FIX routing, B2BITS provides the technology stack and tools to scale securely.
Unified Monitoring & Administration
Both FIX Antenna engines and FIXEdge include real-time monitoring and administration interfaces, enabling comprehensive observability, session management and control across the entire FIX stack from a central dashboard.
