Introduction Scope and Readership This document provides Member Firms with the knowledge and technical details that are required for accessing and trading on the London Stock Exchange Derivatives Market (LSEDM). It also provides essential information for other users such as independent software vendors (ISVs) in regards to the functional design of their applications in order to interface with SOLA using the native SOLA Access Information Language (SAIL) protocol, FIX and High Speed Vendor Feed (HSVF) protocol. Market Participants who require further technical details may refer to the Technical Specifications on FIX/SAIL protocols and HSVF Market Data which are made available in the ‘Technical Specifications’ section of the LSEDM Document Library. Relevant Exchange Communication Channels The SOLA Access Information Language (SAIL) is the native protocol for LSEDM’s trading system, e.g. the management of orders and Market Maker quotes. The Financial Information eXchange (FIX) protocol is a messaging standard developed specifically for the real-time electronic exchange of securities transactions. FIX is a public-domain specification owned and maintained by FIX protocol Ltd. The High Speed Vendor Feed (HSVF) is the SOLA native market data dissemination feed; it is a high speed transmission protocol which broadcasts real-time trading and market statistics from SOLA including information on trades, quotes, market depth, strategies, bulletins, summaries and other statistics. HSVF uses a TCP/IP broadcast interface and standardised message formatting. 6 LSEDM TRADING SERVICES DESCRIPTION 19 November 2018 2.
