605 Reports - Disclosure of Order Execution

Securities and Exchange Commission Rule 605 (formerly Rule 11Ac1-5) requires that market centers that trade national market system securities disclose monthly electronic reports about the quality of their executions on a stock-by-stock basis based on the previous month’s trading activity.

This information may not be directly comparable to data displayed by other market centers due to differences in market structures and computation methods.

While Cboe has used reasonable efforts to prepare these reports in compliance with Rule 605, these statistics have not been audited and may contain errors. Accordingly, any decision about whether to send orders to the Cboe exchanges should not be based solely on these statistics.

The information provided is bound by the Terms and Conditions for Use of Cboe Websites.

Cboe has reported all trade data for Aug 2019. Users should note that anomalies could be present in the Aug 2019 data due to the 8/12/19 SIAC outage.
