StockSharp FIX Infrastructure Is Now Available in the Public Repository

FIX remains one of the core protocols used in professional trading infrastructure. Key StockSharp FIX components are now available in the platform's public repositories.

The published infrastructure includes:

• Fix.Core — core primitives and protocol message processing;
• Fix.Dialects — dialects and extensions for individual trading systems;
• the FIX connector, which maps the protocol to StockSharp's unified message model.

This separation allows a project to use exactly the layer it needs. Developers can add the ready-made adapter to a StockSharp application, adapt an existing dialect, or use the core components as a foundation for a custom gateway under the terms of the StockSharp EULA.

For developers of exchange and trading infrastructure, it is particularly useful to be able to trace the complete message path: from FIX fields to an order, trade, or market event in the StockSharp model. This simplifies integration diagnostics and adaptation to non-standard extensions used by a counterparty.

StockSharp's common message model isolates trading logic from the details of a particular FIX session. Applications continue to work with familiar orders, trades, and subscriptions, while the protocol layer converts them into the required dialect.

The core infrastructure source code is available in the StockSharp repository, while ready-made integrations are hosted in StockSharp/Connectors.

Publishing these FIX components is another step toward making StockSharp's integration layer easier for trading-system developers to understand and extend.
