I comment in support of S7-18-23 The actions below that would be enacted were this proposal to be enacted would be beneficial to small and mid sized firms. * Prohibit exchanges from offering volume-based transaction pricing in connection with the execution of agency or riskless principal orders in NMS stocks. * Require exchanges that offer volume-based transaction pricing in connection with the execution of proprietary orders in NMS stocks for the account of a member to have anti-evasion measures, including rules requiring members to engage in practices that facilitate the exchange’s ability to comply with the prohibition, and written policies and procedures reasonably designed to detect and deter members from receiving volume-based pricing in connection with the execution of agency related orders in NMS stocks. * Require exchanges that offer volume-based transaction pricing in connection with the execution of proprietary orders in NMS stocks for the account of a member to submit electronic, machine-readable structured data tables of certain information about their volume-based transaction pricing tiers and the number of members that qualify for each tier in an Interactive Data File in accordance with Rule 405 of Regulation S-T, which the public would be able to access through the Commission’s EDGAR system.
