Users will be able to mass cancel and block orders using the Investor ID, i.e.,  an individual 12-digit code used to identify the investor who is trading, according to chapter 14.5.3 Investor ID of the Rulebook, available at Entrypoint Order Entry Messaging - Rules.

This means that, when a user cancels multiple orders using the Investor ID, they may cancel all orders belonging to that user and block the entry of new orders.

This way, investors will have a higher level of control over their orders and will be able to mass cancel orders much faster and with fewer restrictions.

Another improvement is that B3 will also make available a new filter called "Asset", which will allow users to cancel any order related to a specific asset.

With all these innovations, we seek to ensure greater control and ease for investors. We are committed to providing an excellent trading experience and these new functionalities are just a few of the advancements we are bringing to market.

More details to be announced soon.

Through the Investor ID, the user can simultaneously cancel all orders belonging to the same investor.

· With the new Mass Cancel on Behalf functionality, user will be able to cancel all the instruments of an asset at once.

· After canceling request, in-flight offers will be blocked.

· The Execution Report will display all sessions that had orders canceled by an Investor ID.

·Several filters may be combined.

Cancel on Behalf will be the solution to optimize the order cancellation process, allowing traders to navigate their trading sessions accurately and efficiently.

As soon as the orders are generated, it will be possible to request their cancellation and the blocking of in-flight offers.

Blocking the entry and receipt of orders serves to prevent orders from arriving after the cancellation command.

After the cancellation request, a reply will be issued and then the cancellation will actually be carried out.

To resume trading, an unblocking message will be issued.
