also would require exchanges that offer volume-based transaction pricing in connection with the execution of members’ proprietary orders in NMS stocks to disclose certain information, including the number of members that qualify for each transaction pricing tier that the exchange offers. The Securities and Exchange Commission proposed a new rule that would prohibit national securities exchanges from offering volume-based transaction pricing in connection with the execution of agency or riskless principal (“agency-related”) orders in NMS stocks. Exchanges would be required to submit this information to the Commission on a monthly basis, and the public would be able to access the information through the Commission’s EDGAR system.
