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.

For a complete description of the messages and their fields, please refer to the associated document:

Self-Trade Prevention (STP) has been introduced on Euronext’s Markets to allow Member Firms performing
specific types of activities (e.g. Market Makers) to avoid trading with themselves.
The STP mechanism allows customers to avoid unintentional self-trading that results from the matching of
two opposite orders1 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 specific
Account Types.
In the event that two opposite orders belonging to the same Member Firm, and applicable account type,
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.
