Mock Trading Sessions – PUMA Trading System

To help participants in planning changes and implementations, B3 will hold mock trading sessions with the market to test the PUMA Trading System, due to system and infrastructure changes.

This Mock Trading Session will cover:

Availability of leg prices in the Execution Report for commodity futures rollover contracts: As of October 10, 2023, commodity futures rollover contracts will include the availability of prices of instruments that make up the legs via Execution Report, as per External Communication 014/2023-VNC dated September 21, 2023.

Validation of the binary gateway parallel production (see initiative): Gateways will be available for order entry validation for all instruments on the trading platform during the trading session, except for instruments mapped on the DRV05 (MarketsegmentID 76 ) and EQT04 (MarketsegmentID 86) trading engines.

Validating receipt of Drop Copy, Admin Session and Firmsoft is mandatory.
 
Drop Copy Service Gateway Update: Drop Copy Service gateways DCPEQT05, DCPDRV02, DCPSMEQT01 and DCPSMDRV01 will be updated with the following points below:

• Removing the Cancel on Disconnect fields from the logon message
• Performance improvements
• Incident fixes

 
LiNe Affinity (see initiative): The fourth LiNe wave will include trading instruments linked to the MarketSegmentID 76 (DRV05), MarketSegmentID 80 (EQT01) and MarketSegmentID 84 (EQT03) trading engines
 
LiNe API: From this mock trading session, a new security layer will be introduced in the middle of data traffic between the client and LiNe.
 
Data security is an absolute priority for B3, and this update represents another step towards an even safer environment for its trades.
 

Binary Market Data (see initiative): The first maintenance release will be carried out on Binary Market Data as per External Communication 077/2023-VNC dated September 7, 2023.
