Market Impact: None - Mock session trades have no financial obligations and will not result in any fund pay-in or pay-out.

Technical Impact: Members should test all trading software, connectivity parameters, and disaster recovery procedures during the mock session to ensure operational continuity.

Impact Justification

Routine mock trading session for commodity derivatives with software version upgrade. Important for operational preparedness but no direct market impact.
