MX Participation in the CIRO(Formerly IIROC) FIA and SIFMA 2023 Disaster Recovery Tests

The Montréal Exchange (MX) will be participating in the aligned Canadian Investment Regulatory Organization (CIRO(Formerly IIROC)), Futures Industry Association (FIA) and Securities Industry and Financial Markets Association (SIFMA) Disaster Recovery tests on Saturday, October 14, 2023, including the pre-connectivity test held on Saturday, September 23, 2023.

This document details the sequence of events during the Disaster simulation. It also provides information on registration, pre-connectivity date and contact information.

The purpose of this test is to establish and confirm connectivity. As stated in the TMX Information Technology (IT) policy, "PING" testing is not permitted, therefore all MX Participants will need to connect to MX systems in order to test and validate connectivity.

MX Participants can test pre-connectivity with the following services:

As long as testing is conducted between 10:00 am and 1:00 pm EDT, no testing appointments are required.

The Derivatives Ops and TMX IT Group support staff will be available to assist. Participants are required to advise Derivatives Ops by phone or email once they have successfully connected (see coordinates on last page).

On Saturday, October 14, 2023 Test Day Timelines Overview

*System will be up at the latest by 11

Pre-Failover

Starting at 7:00 am EDT, the Primary site (MCC) will be up and running and participants will be able to engage connectivity.

• Selected instruments will be in a pre-open phase. No trading will occur.
• MX will not be using its production database for these tests. The order book will be empty when tests begin. Orders must be entered with October 26 date (day orders only)

Disaster Simulation and Recovery

Between 8:45 am to (latest) 11:00 am

➢ 8:45 am: MX will abruptly interrupt SOLA trading. In the approximate 15 minutes that follows, POP access will also be interrupted. In consequence, the primary site will be isolated by a network failover.

Post-Failover

Between 10:30 am - 11:00 am EDT, MX will have switched over to the back-up location in Toronto (DR site known as TCF).

• Immediately following the conclusion of our recovery process, we will offer a 15-minute pre-open period, followed by an instrument state change to allow for continuous trading. Products will remain in a tradable state until 1:30 pm EDT.
• There is no continuity between the pre-open session and this one. Our back-up system will start as if it were a new day. If you were previously connected to our system, please make sure to reset your system to avoid de-synchronization of messaging.
• All orders entered during the pre-failover period will be in the system except to while connected ( as everyone will get disconnected) and BulkQuotes messages.
• Order book reconciliation will be possible through:

• SAIL users: AF message (Order Request)

• FIX users: AF message (Order Mass Status Request) - Please refer to the Disaster Recovery Client Impact Guide available on our webstore(www.tmxwebstore.com)

• During the test, MX Participants and ISVs will be able to connect to the MX Production network (IP & ports) from their Disaster Recovery (DR) environment. MX will redirect participants to the MX DR environment in a seamless fashion if connectivity exists to the DR site (TCF).
• MX Participants must be in a position to maintain their connectivity to the MX from TCF. MX will ensure connectivity.
• MX POPs are located in Markham, Toronto.
• Participants will not be required to make network, DNS, or IP changes in order to connect to the MX DR site during the tests.
• MX will provide bids and offers for instruments. Participants will be able to lift or hit MX market. Firm IDs (mnemonic) representing the MX will be 901 and 902. ➢ During the exercise MX will be sending periodic status emails.

Scheduled testing appointments are not needed. If required, the Derivatives Ops and TMX Group IT support staff will be on-site and available to assist.

Please note: Tests will only be considered conclusive if a participant has executed at least 2 trades during the post-failover.
