2025 - PUMA Trading System
To assist participants in planning changes and implementations, a mock trading session of the PUMA Trading System will be held on June 28th, 2025, with market participation.
In this session, the following system and infrastructure changes will be validated:
- Adjustments to the Transaction Timestamp on Binary UMDF messages.
Adjustments and equalizations on the TransactTime (T5) field will be implemented:
- For the ExecutionSummary message, the AggressorTime and TransactTime fields are currently equal, but they will be adjusted to reflect the expected T4 and T5 values.
- For the SecurityStatus and SecurityGroupPhase messages, the TransactTime will be adjusted to reflect the correct timestamp for when this event occurred in relation to the trade messages in auction cases.
- In the case of Stop Orders, the TransactTime and AggressorTime will always be the same value of the order that initiated the event.
