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.

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.

Specific enhancements for the 2024 peak season include new treatment for votes originating from the same investor and custodian, which were previously rejected for duplicity. Performance improvements were also implemented to generate the vote map. In addition, B3 made improvements to the CICORP system, including an adjustment to minimize errors when selecting ISIN numbers during Distance Voting Bulletin (BVD) registration. None of these changes require market adaptations.

B3 has changed the concentration limits for open positions for the lending, forward and options markets. These limits are calculated based on the free float of shares and will now be 10% for each investor or group of investors, considering each market separately. Furthermore, groups of instruments will be created to aggregate positions from these markets, with a 15% limit applied to the free float. This means that if an investor uses 10% of their portfolio in one of the markets, only 5% will be available for allocation to another market within the group. The change aims to offer greater flexibility to participants, allowing for a better distribution of limits according to their investment strategies.

B3 has improved the filter functionality in the Subscription and Priority Offer modules of its post-trade platform – RTC (Real Time Clearing) – to facilitate the return of subscription rights by position or instrument. Previously, this process had to be carried out contract by contract, which required more time and operational effort. With the new solution, participants will be able to fill in the total quantity available for return in lots. Furthermore, the quantity field will remain editable, allowing clients to opt for a partial return, according to their needs.

To render contract management more efficient, B3 implemented the functionality rejection per lot on its post-trade platform, RTC (Real Time Clearing). Currently, participants need to reject each amendment, renewal or early settlement individually. With this improvement, clients can reject all available transactions at once, providing greater agility and convenience to the process.

This improvement will bring greater quality to the generation of debentures reference prices, making it more robust and complete.
