Following the implementation of the Post-Trade Solution for Fixed Income Private Securities (Flow II), in some cases, the number of allocations exceeded the limit of the current message (bvmf.234), making it impossible to send the status of the trade. In this respect, we will implement an improvement to the flow, creating a new message (b3.296), which will be paginated and will allow the institution to receive the status of all allocations made.

B3 will implement an optional field in securities lending to provide custodians with visibility of the give-up participant ID for executed trades. The information will provide greater transparency and speed up the validation of orders entered by managers. It will be available both via message and on the electronic trading platform, streamlining and improving the validation of offers. For technical details, see the catalog on the project page.

Today Custodians are unable to correctly validate the manager's orders, since they do not have sufficient information to identify the Give-up Participant in securities lending trades. An optional field will be created whereby the Custodian receives data on the Give-up Participant’s ID for trades executed in the securities lending market, thus facilitating their daily trade validation routine. Such data will be available via messaging and via electronic trading platform.

Improvement of the UDS interface will occur when strategies with Options are created. Previously, users had to enter all relevant option data ("Expiration", "Underlying Asset", "Type" and "Strike Price") so that the option ticker could be generated by the system. With the implementation of this improvement, users will only need to enter the option code in the specific field on the strategy creation screen. This will lead to automatic filling with all the data needed to create the UDS. However, the "C/V" (call or put) and "QtdLote" (quantity) fields must be completed. With the change, the "Code" field will be repositioned to the left of the screen, right after the "Market" field.
