Scope of Mock Trading Session - PUMA Trading System

Event Date

04/27/2024 to 04/27/2024

Time

From 10:30 Until 12:30

To assist participants in planning changes and implementations, a mock trading session of the PUMA Trading System will be held on 04/27/2024, with market participation.
In this session, the following system and infrastructure changes will be validated:

• First wave of the Matching Engine update:
Implementation of the first wave of the new version (bugfixing), specifically for the Matching Engine listed below:

MarketSegmentID

68 (DRV01) e 70 (DRV02)

80 (EQT01) e 98 (EQT09)

Waves 2 and 3 will be held on 3rd and 05/10/2024, respectively.

• Update of LiNe Trading for improvements and corrections:

New LiNe Trading version implementation to correct the block trading instruments classification that will now be presented in the same Authorized Market group of its underlying instrument.

• LiNe Clearing Update:
New LiNe Clearing version implementation, without impact to participants.

• FIX Gateway Version Update - Entrypoint:
Preparation for the migration of FIX Gateways that will receive Execution Reports in binary and convert them to the FIX protocol.

Currently, the FIX trading gateways receive messages in the FIX format. However, with the update we will make to the Mock Trading Session, all FIX gateways will receive messages in Binary format. They will then convert these messages to the FIX protocol and send them to clients, ensuring that there is no impact beyond what is stated in the CID document available on the B3 website or changes to the FIX protocol.

This will be implemented specifically in the Gateways:

FIX Gateways	OE002, OE208, OE225, OE022, OE226, OE227, OE228, OE229, OE230, OE231, OE165, OE166, OE167, OE168, OE169, OE170, OE027, OE232, OE001, OE003, OE091, OE112, OE082, OE083, OE084, OE073, OE074, OE075, OE076, OE077, OE078, OE079, OE080, OE081, OE096, OE097, OE098, OE099, OE100, OE101, OE102, OE103, OE104, OE105

• New Drop Copy Gateway version:
Implementation of a new version of the Drop Copy Gateway to enable the migration of gateways to receive Execution Reports in Binary and convert them to the FIX protocol.
