FX Trading - PriceStream Taker API

Introduction

The FX Trading – PriceStream Taker API provides FIX-based access to executable streaming FX liquidity available on the LSEG FX PriceStream venue. The API enables clients to subscribe to real-time prices from participating liquidity providers and execute trades directly against available liquidity through a standardized FIX interface.

The API supports FX Spot, Precious Metals, and Non-Deliverable Forwards (NDFs). Clients can discover available instruments, request full-depth or top-of-book pricing, and manage the complete trade lifecycle through order entry, execution reporting, order status, and cancellation workflows.

Built on the FIX 5.0 SP2 protocol, the API uses dedicated market data and trading sessions for market data distribution and trade execution.
