SEC notice on Cboe EDGX’s proposed Level 3 trading-halt rule change

The SEC notice concerns a proposed Cboe EDGX trading-halt rule change, not a government purchase. - Government agency: U.S. Securities and Exchange Commission (SEC). - Filing entity: Cboe EDGX Exchange, Inc. - Proposed change: Amend Exchange Rule 11.24(b)(2) so that after a Level 3 market-wide circuit breaker halt, trading resumes no earlier than 4 a.m. on the following trading day, even under a planned 23-hours-per-day, five-days-per-week trading schedule. - Purpose: Preserve the existing cooling-off period and support orderly markets and price discovery; the proposal does not substantively change the circuit-breaker mechanism. - The notice invites public comments. No products, services, quantities, part numbers, contract value, or procurement vendors are identified.

The notice states that the proposal is intended to preserve the existing market-wide circuit-breaker resumption practice and does not make substantive changes to the mechanism. The Commission is soliciting comments on the proposed rule change.
