In a world where financial markets move by the millisecond, real-time data delivery isn’t a luxury—it’s a necessity. But delivering that data consistently, especially to clients with variable bandwidth, mobile devices, and different processing capacities, is a complex task.
At dxFeed, we’ve built dxLink WebSocket to meet that challenge head-on. This is our next-generation market data distribution product, engineered to perform under pressure, adapt in real time, and ensure that every client—no matter their device or connection quality—gets the most relevant, timely market information.
Built for Modern Market Demands
Many legacy systems were not designed with mobile-first or low-bandwidth environments in mind. They can be prone to data loss, inconsistent latencies, or overwhelmed clients during peak activity.
dxLink WebSocket changes the equation. It’s designed specifically to handle:
- Mobile clients with intermittent or slow connections
- Bandwidth-constrained environments
- Clients with varying processing capabilities
- The need for consistent and up-to-date data across all endpoints
Smarter Data Flow: The dxLink Architecture
At the core of dxLink WebSocket is a series of intelligent systems working in tandem to ensure smooth and adaptive data delivery.
Intelligent Backpressure Management
The solution detects each client’s data consumption speed and dynamically adjusts the flow, ensuring data is delivered at the optimal rate for every connection.
Conflation Engine
Redundant market data are automatically removed, leaving only the most recent and relevant updates—especially critical during high-volatility periods. This keeps the information fresh and manageable, without overwhelming the end-user.
Load Balancing and Resource Scaling
Whether you’re supporting hundreds or millions of users, dxLink WebSocket ensures fair resource distribution across clients. It even predicts usage spikes using historical data and scales resources ahead of time to maintain performance.
Developer-Centric Design
Integration is straightforward. dxLink WebSocket uses a clear and consistent WebSocket protocol with:
- JSON-based payloads for easy integration
- Binary options for high-volume or latency-sensitive applications
- Standardized message formats for seamless cross-platform support
We also offer:
- Prebuilt SDKs for JavaScript, Java, C#, C++, Swift, and Kotlin
- Sample applications and a full developer sandbox
- Interactive API documentation and integration support
Flexible Deployment for Any Infrastructure
Whether you’re deploying in the cloud, on-premises, or via a hybrid model, dxLink WebSocket is ready:
- Cloud-native support across major platforms
- Low-latency on-prem deployment options
- Hybrid configurations for enterprise-scale customization
- Global delivery network for latency-sensitive scenarios
Adaptive to Real-World Conditions
dxLink WebSocket adjusts automatically based on device and network performance:
- For mobile: it uses connection-aware streaming, intelligent prefetching, and battery-optimized update patterns
- For unstable or slow connections: it provides aggressive data conflation, priority-based delivery, and configurable QoS tiers
Built-in Security and Observability
Security and operational transparency are non-negotiable. That’s why dxLink WebSocket includes:
- TLS 1.3 encryption on all connections
- Fine-grained access controls by instrument and event type
- Rate limiting and DDoS protection
- Real-time dashboards and automated alerts for monitoring and diagnostics
Why It Matters
dxLink WebSocket represents a significant leap forward in how real-time financial data is delivered. It adapts to clients, scales intelligently, and ensures the right data reaches the right user—fast, clean, and secure.
If your business depends on delivering real-time market data to users across various environments, dxLink WebSocket is the foundation you can trust.
