The Financial Industry Regulatory Authority, Inc. is filing with the Securities and Exchange Commission a proposed rule change to adopt FINRA Rule 4553 (Fees for ATS Data), that would establish a fee schedule for optional professional and vendor access to alternative trading system (ATS) volume information (as required to be submitted by ATSs in a weekly report to FINRA under FINRA Rule 4552) published by FINRA on its website. Non-professionals (i.e., natural persons who use the information for their own personal, non-commercial use) will continue to be able to access the ATS volume information free of charge. 

More information on the proposed rule can be found here.
