Currently, some clients use data from the UP2DATA Legacy/Old channel files, but they are changing their systems/reading to files with the UP2DATA format. The data contained in the Legacy/Old channel is stored in several different files, making it difficult to find the necessary similar fields.

The data contained in the Legacy/Old channel is stored in several different files, making it difficult to find the necessary similar fields. Therefore, the main benefit of this activity is the "map" from the Legacy file to the UP2DATA file, which will make it easier to find the fields in the files.   - Increase in the history and update of the website glossaries - Public Data Website.  - Addition of site variables - Public Data Website: Fields with data on fluctuation, registered quantity and financial volume will be included.

Currently, the files that are generated in the Institutions' deposit bag and that bring data on all transactions carried out during the day are not generated at the same frequency between products. This means that some instruments have files generated only after the batch, while the last generation of the other instruments is done before the registration window is closed, leaving out trades entered after this time limit. The purpose of this delivery is to equalize this process so that for NDF Currencies, NDF Commodities and NDF Options (non-CCP), the transaction file is generated more than once a day to streamline matchings and also at the end of the registration window, thus consolidating all the data entered by the Institution on that date.

Currently, the file provided by B3 for Clients to validate Non-CCP Options contracts contains diverse data. However, if the contract is the "Asian average" type, only verification date quantities for calculating the expiration price are displayed, leaving out the dates actually registered at the time of registration. The purpose of this delivery is to create a specific file for Non-CCP Options containing Asian average dates and other contract characteristics to facilitate daily reconciliation by clients and optimize operational routines of institutions that register this product. It will be available in the Participants' deposit bag.
