Improvements

Orders

We have implemented significant improvements to the workflow for brokers and execution desk traders, enabling more efficient management and resolution of FIX care order rejections. Previously, errors in inbound FIX care orders resulted in immediate rejections to the client. Going forward, the majority of these orders will be processed and displayed in the TT front-end within a new "Order Exceptions" widget. FIX care orders with exceptions will not appear in the standard Order Book widget or the Orders and Fills Widget (OFW); instead, they will be displayed in this new widget, which provides "Repair" or "Reject" action options for direct management of these error orders.

Exception orders will be routed through the regular TT account specified on the order, unless the error pertains to the account indicated on the order. In such instances, the exception order will be routed through the "error account" associated with the FIX session. Companies should map these error accounts to the users who will be utilizing the exception management functionalities. Please note that users must have OMS Advanced features enabled within Setup to access this new functionality. More detailed information will be forthcoming in our documentation.
