SEC Rule 605
The SEC's customer disclosure rule, SEC Rule 605, requires market centers to disclose monthly data about the quality of their trade executions. Each monthly report will disclose execution quality data based on the previous month's trading activity.
The reports for Fidelity's market centers can be accessed below.
Pursuant to the "Joint Industry Plan; Order Approving Plan Establishing Procedures Under Rule 605," the execution quality data provided in the reports must be in a standard format.
