Euronext Cash Markets - Optiq Kinematics Specifications – v1.3.1 Cash - regulated markets

This document provides an overview of the exchange of messages between the Optiq Order Entry Gateway (OEG), the clients’ systems and the Market Data Gateway (MDG). It includes:

■ Typical trading scenarios and the corresponding public and private messages for these scenarios, and the different cases they may cover;

■ The names and IDs of the messages sent;

■ The events that trigger the transmission of messages.

This overview is meant to provide a description of the main structures and concepts used within this document, to facilitate the review of the individual topics and cases covered within.

The messages that are sent between trading members and Optiq are referred to as private messages whereas the messages that are sent by the external broadcasting systems are referred to as public messages.

Private messages are exchanged exclusively between the clients’ system and the Optiq matching engine via order entry gateways, for example to request information from the system or to issue a command (e.g., enter an order). Private messages are also sent back by Optiq via order entry gateways (OEGs) to the client’s system to provide the information requested, or confirm that a command has been successfully executed (or not), as well as to notify of trades, etc.

Public messages are sent by Optiq via MDG to provide to all subscribing clients with anonymized Market data, such as orders entered, best limits, trades executed, market events, updated limits, etc.

The diagrams in this document express representative examples of message sequences and other scenarios can be figured out from the ones described inside that document. The details of the message contents may vary depending on the example.

The diagrams also endeavour to represent as close to reality as possible the sequence in which events and steps occur, and messages are sent. This introduction provides indication when such cases are not feasible to represent faithfully due to complexity of graphical representation.

Euronext Cash Markets - Optiq Self-Trade Prevention (STP) Functional Overview – v1.3 Cash - regulated markets

Self-Trade Prevention (STP) has been introduced on Euronext’s Cash Markets to allow Member Firms acting as Liquidity Providers to avoid trading with themselves. The STP mechanism allows customers to avoid unintentional self-trading that results from the matching of two opposite orders on the same instrument, of the same Member Firm (i.e. with the same Member Code). The mechanism applies to orders that are submitted via private messages (SBE or FIX) with the Account Type of Liquidity Provider (LP). In the event that two opposite LP orders belonging to the same Member Firm would match against each other, the mechanism cancels either the resting or the incoming order (depending on the STP Type chosen). If STP Type chosen is “Cancel Resting”, then the system enters the incoming order of the possible match, into the central order book. If STP Type chosen is “Cancel Incoming”, then no changes occur in the central order book and the incoming order is rejected.

Exchange For Physical - Functional Overview - v1.3 Derivatives

An Exchange for Physical (EFP) is a transaction involving the simultaneous exchange of a futures position for a basket of shares.

EFPs based on index futures are transactions made on the basis of the difference between the index futures price and the spot price of the index. Currently, the futures leg of these transactions can be reported on Euronext’s Basis Trade Facility, with reference to a cash leg. Euronext’s new Exchange for Physical Facility enables members to trade EFPs on the CAC 40® and AEXIndex® by simultaneously exchanging index futures for the corresponding basket of underlying component securities of the index. The new EFP solution will be available for trading in a regulated environment by means of a transparent central order book supported by a liquidity-providing scheme. Trading of EFPs takes place by means of a fully automated straight-through-process, eliminating operational burdens and facilitating post-trade reporting obligations. In addition, it reduces execution risk thanks to the guarantee of the central counterparty.
