TT has added support for the OMW options on the MIAX_FUT_CH market on TT. Customers who are already configured to trade on the MWE futures on this market on TT, can trade on the option contracts without requiring any setup changes on TT.
This release also includes enhancement to the total traded volume calculations as per the message structure enhancements implemented by MIAX. As per this -
- For a trade between outright orders on simple instruments - the total volume will be updated on the simple instrument only
- For a trade between complex orders - the total volume will be updated on the complex instrument as well as on the involved legs
- For a complex trade with implied / leg orders - the total volume will be updated on the complex instrument as well as on the involved legs

Introduced on-the-fly strategy creation through AB/D order messages for both DMA & staged order types through FIX OR.
1. If FIX OR does not find the strategy combination in PDS based on the legs in the order, a request will be sent to the exchange to get the strategy created.
2. If the exchange rejects the request, the order will be rejected.
3. If the exchange accepts the request, FIX OR holds on to the order until it receives a notification from PDS that the instrument is available in TT.
4. When FIX OR receives the PDS notification, it routes the order to the exchange.
5. If FIX OR does not receive the PDS notification within (60) seconds, the order will be rejected.

Updates on the FIX XML file
1. Introduced a new optional tag, 'BrokerRoute' (18233), to the ExecutionReport (35=8), OrderCancelReplaceRequest (35=G), OrderCancelRequest (35=F), OrderCancelReject (35=9), MultilegOrderCancelReplace (AC), NewOrderMultileg (35=AB), and NewOrderSingle (35=D) messages. The 'BrokerRoute' (18233) tag is now available in the TT XML file. This tag will be populated only on FIX Order Gateway orders, and only if a value is defined for the 'Route' parameter under a FIX Order Gateway connection in TTUS. This feature will be available in an upcoming TT release.
2. Enum values 125:ORDER_PASSING_REQUEST_INITIATE and 126:ORDER_PASSING_REQUEST_UNDO under tag 378 (ExecRestatementReason) are available in the v295 XML.
3. Introduced a new optional tag 'OneOffSharedKey' (20000) in the TradeCaptureReport (35=AE) message. This tag must be included in TradeCaptureReports (35=AE) sent through TT FIX Order Routing sessions for GFO-X block trades. It is used to define the common text between the two parties of the block trade that confirms the match.

Care orders with some untranslatable FIX tags ( instrument, account, user parameters, price, quantity, order type, side) will route to TT and remain in repair mode.
This allows users to review and correct the data before resubmission through the 'Order Exception' widget in TTW. Users can also review and reject the order in this mode.
When a care order is placed in repair mode, an Execution Report (39=0/150=0) will be sent through FIXOR but there will be no messages through the FIX drop copy session (if configured).
When a care order is corrected and resubmitted successfully from repair mode, a restated Execution Report (39=0/150=D) will be sent through FIXOR and a new Execution Report (39=0/150=0) will be sent through FIX drop copy session (if configured).
If the care order is rejected while in repair mode, a rejected Execution Report (39=8/150=8) will be sent through FIXOR and FIX drop copy session (if configured).
Please note that users must have OMS Advanced features enabled in TTUS to access this new functionality.
