FX Trading - PriceStream Liquidity Provider API
Introduction
The FX Trading – PriceStream Liquidity Provider API provides FIX-based access for liquidity providers to stream executable FX prices to the LSEG PriceStream venue. The API enables participants to publish and manage executable prices, and process executions against their streamed liquidity.
The API supports FX Spot, Precious Metals, and Non-Deliverable Forwards (NDFs). Liquidity providers can respond to quote requests with executable quotes, manage quote updates and cancellations, and receive execution reports throughout the trade lifecycle.
Built on the FIX 4.4 protocol, the API uses dedicated quote and trading sessions to support integration with proprietary pricing, trading, and risk management systems.
