08/21/2024	08/21/2024		Plan	Order Entry	IMPORTANT NOTE: UPDATED TT will be migrating to the SAIL B4 version this weekend. Starting on August 26, TT will adopt the SAIL B4 version. Clients will have until August 25 to link their session IDs and complete testing in UAT. Failure to do so will result in the denial of order entry session login by the exchange. On the MX Axis portal (https://www.tmx.com/axis/login/), link the session ID to 'Order Connector v255 - B4'. This upgrade introduces new fields for regulatory compliance. While MX does not require these fields to be populated until March 31, 2024, TT will send them to MX if they are filled in. These fields will be configurable in TT User Setup under Accounts. Please use the corresponding TT fields to set the compliance fields: 1. Unique ID: <Investment Decision ID> Alphanumeric field, max 10 characters 2. Sponsored Access Flag: <Direct Electronic Access (DEA)> Yes/ No drop -down on accounts 3. Client Short Code: <Client ID> Numeric only field, max 10 characters 4. Algo Trading Flag: <Investment Decision Qualifier> Yes/ No drop -down on accounts Note: 1. When none of the new fields are set, the order will not be denied by MX. 2. When the “Instrument Decision ID” or “Client ID” fields are configured with more than 10 characters, the order will be denied internally by TT. The denial message will state: “Exchange does not support UniqueID or ShortCode greater than 10.” 3. The “Client ID” must be numeric only. If it is configured as an alphanumeric value, such as “Client123”, the order will be denied internally by TT with the message: “Exchange does not support negative or invalid short code.” FIX clients can override all these fields with the following tags: Investment Decision ID (tag 448), PartyRole (tag 452), Investment Decision Qualifier (tag 2376), Client ID (tag 448), and Direct Electronic Access (tag 1724). For additional information, please refer to: https://www.tradingtechnologies.com/support-updates/ (UPDATED: MX: API Upgrade: Client Identifiers). https://reg.m-x.ca/en/requirements/client-and-order-identifiers (Ref 169786)
