To assist participants in planning changes and implementations, a mock trading session of the PUMA Trading System will be held on 02/24/2024, with market participation.
In this session, the following system and infrastructure changes will be validated:

•    Cryptocurrency Futures Contracts:
Availability of the new Cryptocurrency Futures Contracts for testing during the mock trading session. At the end of the mock trading session, the following contracts will be removed from the platform:

The release date of the Cryptocurrency Futures Contracts will be informed in due course.

• Preparation of LiNe for new functionalities:

Implementation of a new version of LiNe, without impact to participants.

• Market Data FIX (UMDFTCP and ePUMA):

According to External Communication 004/2024-VNC, released on 02/08/2024, validation will be done for FIX/FAST Conflated, FIX/FAST UMDF and ePUMA Market Data being produced through Market Data Binary, specifically for the following channels:

• Purge Gateway Infrastructure

Availability of the Purge Gateway infrastructure for internal testing by B3 will be provided. However, at the end of the mock trading session, the gateways will become unavailable as this service requires regulatory approval for the launch of the Mass Cancel on Behalf functionality, which will be exclusively processed through these gateways.

Technical details about the project can be consulted here.

• LiNe Clearing Update:

Currently, trading engines generate FIX Execution Report and Binary Entrypoint (SBE). From this version onwards, all Clearing Risk Centers will no longer receive FIX Execution Report and will start receiving Binary Entrypoint Execution Report.

• Recovery Systems:

Currently, trading engines generate FIX Execution Report and Binary Entrypoint (SBE). From this version onwards, B3's recovery systems will start consuming Binary Entrypoint, which will convert the messages to FIX.
