Order Entry

In July 2024, TT introduced support for the MX SAIL B4 version, which included four new fields for regulatory compliance: Short Code, Unique ID, Sponsored Access Flag, Algo Trading Flag. For more details on this release, refer to the https://library.tradingtechnologies.com/downloads/MX_SAIL_B4_API_Upgrade.pdf . In response to customer feedback, TT has introduced a new order tag default (OTD) field called “Order Origination Firm” on accounts which can be used to set the Unique ID field. Rules for setting Unique ID: -When Investment Decision ID is configured, it is used to set the Unique ID. -When Order Origination Firm is configured, it is used to set the Unique ID. -If both Investment Decision ID and Order Origination Firm are configured, Order Origination Firm takes precedence and is used to set the Unique ID. . AlgoTradingFlag configuration The AlgoTradingFlag can be configured using two approaches: 1. Investment Decision Qualifier (IDQ): (Tag 2376) -Using the Investment Decision Qualifier (IDQ) on accounts -FIX users can set this using the [PartiesGrp] tags: 453 (NoPartyIDs), 448 (PartyID), 452 (PartyRole), 2376 (PartyRoleQualifier) Values for 2376: 22 = Algo, 24 = Natural Person . 2. [OrderAttributeGrp]: (Tag 2595): FIX users can set the AlgoTradingFlag using the following tags: 2593 (NoOrderAttributes) = 1 2594 (OrderAttributeType) = 4 2595 (OrderAttributeValue): Y for AlgoTradingFlag = Yes, N for AlgoTradingFlag = No . Note: No new fields or OTDs have been introduced for the OrderAttributeGrp. This enhancement does not impact the previous implementation of the MX SAIL B4 upgrade.
