NYSE Arca, Inc. (Arca or Exchange) submitted a rule filing with the Securities and Exchange Commission to establish the Risk Management Gateway (RMG) service as a facility of Arca. The RMG facility is intended to assist Exchange Equity Trading Permit Holders (ETP Holders) in monitoring and overseeing the activity of “sponsored access” customers. The facility will enable sponsoring ETP Holders to route sponsored customer orders through an Exchange-provided risk filter before such orders are routed to the Exchange’s trading systems for execution. The facility's software will review orders passing through the filter to determine whether the orders comply with certain preset parameters established by the sponsoring ETP Holder.
