Cboe Options is changing Rule 5.31, which governs how its system starts the opening auction for equity options during Global Trading Hours. The rule sits alongside a recent approval allowing some multi-listed equity options to trade outside regular U.S. market hours. The practical effect is mainly operational. Options traders, market makers, brokers, and compliance teams that support Cboe Global Trading Hours should review the updated opening-auction process and make sure their systems and procedures match the new timing rules.
