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.

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).

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.
