Please consult the MiFID II Migration Guidelines.

MiFID II identifiers will be mandatory as of 3 January 2018.

As of 3 January 2018, Euronext will apply technical controls on all MiFID II fields for Euronext Derivatives and will reject an order with an error message if mandatory and conditional fields have not been populated as required.

For Euronext Cash Markets, prior to the implementation of Optiq, Euronext will not reject an order if mandatory or conditional fields have not been populated as required. However, Members are strongly reminded to not change the way Rule80A is currently populated in order entry to match with the relevant Trading Capacity, as this may lead to an order rejection.

Euronext will not validate short codes upon order entry or reject orders if short codes have not been declared ahead of trading.

Euronext will inform Members at T+2 of missing short codes via email.

Members are required to report short and long Code mapping data to Euronext for trading day ‘D’ before 10:00pm CET at D+1.

SLC Manager is available on week days from 06:30am CET until 10:00pm CET. The service is unavailable beyond such times and reports submitted after 10:00pm CET will be rejected.

Members are not required to submit a mapping file every day, but only when there is a change to the short and/or long code data.

A short and long code combination can be the same for CodeTypes ExecutionDecisionWithinFirm and InvestmentDecisionWithinFirm. One short code can be mapped to only one long code, but one long code can be mapped to more than one short code.

Yes, SLC uploads are required per Member Code for which separate log-in credentials are required.

Euronext uses a concatenation of the value of the Execution (or Trade) ID and the ISIN code to generate TVTIC.

For Cash markets, the field to use for execution ID, per protocol is:

• SBE: Execution ID
• FIX: ExecID (tag 17)

For Derivative Markets, Euronext leverages the field TradeID.

ISIN Code is the field retrieved from standing data for the associated instrument.

Please consult the MiFID II Guidelines for the provision of data for RTS 22 and RTS 6.

Please consult the MiFID II Guidelines for the provision of data for RTS 22 and RTS 6, available here, as well as the Guidelines to implementing MiFID II requirements for Euronext Cash Markets.

Conformance tests apply only to trading applications and algorithms that interact directly with the Euronext API. Please consult the Conformance test and Algo Declaration Policy

The Member is responsible to ensure that an algorithm has been properly tested. However, the Member may rely on a vendor for these purposes.

By using an algo in production, a Member self-certifies that the algo has been properly tested.

Algo declaration is performed through the upload of a short code and long code mapping file via SLC Manager

Assigning short codes and long codes to algos is the responsibility of the Euronext Member. However, the Member may rely on the ISV for these purposes.

Euronext has made available a Market Making Agreement in accordance with MiFID II regulation. Algorithmic traders pursuing Market Making activities will be required to enter into the Agreement. Market Makers who have entered into the agreement will be required to post firm, simultaneous two-way quotes of comparable size and competitive prices. They must also deal on their own account for at least 50% of the continuous trading session during at least half of the trading days over a single calendar month period.

In addition to the Market Making Agreement, Euronext has introduced a range of Market Making Schemes to replace certain Liquidity Provider programmes on equities, ETFs, and financial derivatives. The Market Making Schemes are subject to the same Terms & Conditions as the Agreement, but with specific quoting obligations per Scheme.

Stressed Market Conditions on Euronext Cash markets will occur following volatility halts due to price / volume changes in securities that are declared to be ‘liquid securities’ by ESMA and subject to a contractual Market Making Scheme.

In a situation constituting a Stressed Markets Condition, the obligation of the participant under the Market Making Scheme to provide liquidity on a regular and predictable basis will be amended to double the spread requirements

For Cash Markets, Members or participants acting as Market Maker or Liquidity Provider on Euronext Cash Markets will be required to flag this activity via account type ‘6’ in Rule80A. For Derivatives Markets, Members or participants acting as Market Maker or Liquidity Provider on Euronext Cash Markets will be required to flag this activity via account type ‘M’ in AccountCode.

More information on the Market Making Agreement and Market Making Schemes is available on the dedicated Euronext webpage.

Based on current National arrangements, third-country firms will be able to access Euronext markets via direct membership.

Based on current National arrangements, third-country firms will be able to access Euronext markets as clients of MiFID II regulated DEA providers. Euronext is currently discussing the application of the ESMA Q&A on DEA providers from third countries with its regulators and providing relevant support to impacted firms.

YNon-MiFID investment firms pass their obligation to report transactions to the venue of execution. Euronext will provide a mandatory transaction reporting services on behalf of non-MiFID trading members. Please contact ccc@euronext.com for more information.

Post-Brexit, UK firms will be regarded as third-country firms but until the terms of the UK’s disengagement from the EU are known (and in particular the position of the UK in respect of the single market), it is difficult to identify the implications for firms’ access to European regulated markets. In the worst-case scenario (total disengagement from the single market), UK firms would have to rely on the arrangements described above.

Euronext will use a DEA Indicator flag in the order entry messages to indicate whether an order was submitted via a Direct Electronic Access (DEA) connection or not. The designation of which clients are DEA clients is at the discretion of the DEA provider.

For Direct Market Access (DMA) clients, Euronext will determine adherence to risk control requirements set forth by MiFID II via scheduled audits and investigations (or information requests).

In the event of a Sponsored Access (SPA) request, Euronext will conduct due diligence in accordance with ESMA regulatory requirements.

Euronext has procedures in place to support members monitoring DEA or algorithmic orders triggering circuit breakers. Furthermore, the Euronext RiskGuard service will provide members with the ability to monitor their DEA Clients and set up a number of risk controls either via a FIX API or a web-based user interface. The service is embedded in the core of the Matching Engine. Any alert resulting from a limit being breached will be generated in real-time. I am a DEA user from a third country, can I continue to access Euronext markets?

Based on current National arrangements, third-country firms will be able to access Euronext markets as clients of MiFID II regulated DEA providers.
