Rule 605 Disclosure of Order Execution Information

SEC 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. MEMX Rule 605 reports are available for download below.

This information may not be directly comparable to data displayed by other market centers due to differences in market structures and computation methods. While MEMX 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 MEMX should not be based solely on these statistics.
