The purpose of this document is to provide customers with a description of the Optiq order entry conformance script, with scenarios for connectivity, functional data conformance and high availability tests for the Phase 2 of the migration to Optiq covering the Euronext Cash markets. Please note that the DR(disaster recovery) testing will be detailed in a future version. 

This document sets out the client messages specifications for Optiq OEG using the FIX 5.0 format. More specifically, it describes the contents of administrative and application messages and provides detailed field descriptions.

Note: Algomi is not in scope of this document.

Drop Copy is a service, providing near real-time copies of trade reports & order messages, usually used by for risk management, back-offices and compliance teams

Clients require a dedicated connection to receive Drop Copy messages, which can be setup with configuration that fits their needs.

The scope of data in Drop Copy could provide client messages for various (or all of their) Logical Accesses, for one, or across different Optiq Segments.

This version of the document covers activity on the Cash market only, that are in scope of Phase 2 of the migration to Optiq.

Euronext is introducing new Large-in-Scale (LiS) features on the Central Order Book. The service will create more opportunities to execute LIS orders, leveraging existing liquidity in the central order book. As soon as market participants implement the necessary modifications required to use the model, including conformance tests, they will immediately be able to benefit from the existing invisible liquidity. The new service is now available for testing on the External User Acceptance (P-EUA) test platform. The launch in Production is planned for the first quarter of 2019.

This document details the Referential Data HTTPS Server for Euronext, to be used in conjunction with the Optiq MDG Client Specifications.

The Servers provide full referential data for the Euronext markets, as well as feed configurations and intraday trades with their MiFID II flags. Users of the Euronext market data feed should use the Servers to:

- Configure feed connections every day.

- Support the referential data that is disseminated on the feed.

- Complete their list of trades.

This document provides all multicast addresses required to access the Euronext Optiq® Market Data Gateway External User Acceptance (EUA). Only shaped data is provided in the test environment. In order to ensure a Production-like test environment, separate IP addresses and ports are used to replicate the Production ‘shaped’ and ‘unshaped’ configuration.

The Euronext Optiq® Market Data Gateway Physical-EUA (P-EUA) environment is located in Basildon and the Virtual-EUA (V-EUA) environment is located at St. Denis. The P-EUA and V-EUA Source IP Address ranges are provided in this document and for P-EUA the Source IP Address ranges are provided for the live and standby systems as part of the High Availability mechanism. EUA High Availability (HA) and failover testing will only be conducted on the physical test environment (P-EUA).

Customers are requested to allow the V-EUA and P-EUA Source IP Address ranges through their Firewalls.

With the XML Standing Data files for the different Optiq Segments, customers will be able to map which instruments are available in which channel. The Optiq MDG feed configuration can be found at the end of each Standing Data file available and these will be provided on a daily basis in XML format. It is required to use the feed configuration details as part of the standing data files to connect to the feed on a daily basis.

In case a new partition is added to an Optiq Segment, customers are required to adapt to this type of change using the Optiq MDG Standing Data files that include the feed configuration details.

This document provides all multicast addresses required to access the Euronext Optiq® Market Data Gateway Production and Disaster Recovery (DR).

The Euronext Optiq® Market Data Gateway Production environment (PROD) is located in Basildon and the Disaster Recovery (DR) environment is located at St. Denis. The Production Primary (P) and Secondary (S) Source IP Address ranges are provided in this document for the live and standby systems as part of the High Availability mechanism.

Customers are requested to allow the Production Primary, Production Secondary and Disaster Recovery (DR) Source IP Address ranges through their Firewalls.

The Euronext Optiq Market Data Gateway (MDG) provides high-speed, real-time market data for Euronext markets.

The data feed has the following high-level features:

■ Multicast technology

■ Ultra-low latency

■ MiFID II compliance

■ Cash & Derivatives message harmonization

■ Optimized feed for each type of connectivity

■ High availability

■ Reliable network solution

■ High level of scalability

■ Access to a wide range of European market data sets

This document provides detailed information about the features of the feed to support the development of client applications.

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.
