No financial transactions are processed, and there are no changes to trading rules or software versions. Members who fail to participate risk connectivity issues on the following live trading day (Monday, March 23, 2026).

Impact Justification

Routine mock trading session for operational readiness; no new software version, no financial obligations, and no regulatory changes. Primarily relevant to trading members for connectivity testing.
