Cboe BZX Exchange Proposed Rule Change to Adopt Rules 11.29 and 11.30 on Trading Halts and Integrate Amended CTA/CQ Plan Definitions
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The Cboe BZX Exchange is proposing to reorganize its trading halt rules by creating new Rule 11.29 (Trading Halts) and Rule 11.30 (Trading Halts Due to Extraordinary Market Volatility). This integrates multiple definitions and procedures from the Amended CTA/CQ Plan to create consistent standards across U.S. exchanges for regulatory and operational halts. The existing Rule 11.18 will be renamed to focus solely on the Limit Up-Limit Down Mechanism, while market-wide circuit breaker provisions move to the new Rule 11.30. The changes aim to improve handling of cross-market events, SIP outages, material latency, and extraordinary market activity through standardized definitions and coordinated halt procedures among SROs.
