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.

Currently, some rollovers have a differentiation in Tag 762 (e.g. Tag 762 = 140 – Financial Rollover, 141 Agricultural Rollover, etc.) identifying the different types of rollovers while EDSs only come with Tag 762 = 90 – Strategy, without this distinction. Therefore, we will include a characterization domain, for example (Tag 762 = xxx – DV01 Neutral and UP Neutral).

B3 has implemented a change to the “expiration code” field in the shortened version of the BVBG.031 (DailyFeeUnitCostReport) file, which is used to inform market participants about the unit costs of fees applicable to trades. From now on, the shortened version, sent to options markets 3 and 4, will only include the month code and the year code, thus reducing the file size. Previously, this field also contained the option type and an alphanumeric sequence. This change was made to accommodate clients who were experiencing difficulties with the current file size.

The submission of orders for block trade solutions Midpoint Order Book (Midpoint) or Book of Block Trade (BBT) via the ePUMA trading station has undergone improvements. The goal is to enhance the user experience and streamline the routine. The update has brought greater ease for investors as the number of fields that need to be filled out when submitting an order will be reduced. Furthermore, the tool automatically locks fields that should not be filled out, thus minimizing the chance of errors. Here's how it works: #Automatic Filling: When the instrument symbol ending in "M" (Midpoing) is entered in the ticker field, the field "Type of market" will be automatically filled as Midpoint, thereby eliminating the need for the user to fill out two fields. # Error Prevention: When the user enters the instrument symbol ending in "M" (Midpoint) or "Q" (BBT), fields that do not need to be filled out will be locked, preventing potential input errors.
