dxFeed is a market data distributor and subsidiary of Devexperts, headquartered in Munich, delivering real-time, delayed, historical, and on-demand financial market data across equities, ETFs, futures, options, indices, FX, fixed income, and crypto (3.5M instruments, ~200,000 simultaneous streaming clients), plus reference data (instrument profiles, corporate actions, trading schedules), Morningstar-sourced fundamentals, options analytics, and news feeds. Delivery is developer-documented but sales-gated - production credentials (endpoint URLs, login, password) arrive via onboarding after contacting sales - across a REST web service with Server-Sent Events streaming, the dxLink WebSocket protocol (public AsyncAPI spec and live demo endpoint), a binary QD protocol over TCP, FIX, file-based historical/tick data extraction, and Java/C++/.NET/Swift/Go/JavaScript/Python client libraries.
