Chicago Mercantile Exchange Group (CME Group) issued an advisory notice on an upcoming rule change that will codify the requirement that every CME Globex order identify whether it was entered by manual or automated means. A manual order is an order entered directly by an individual into a front-end system and which is routed in its entirety to Globex at the time of submission. An automated order is an order that is generated and/or routed to Globex without human intervention. The advisory clarifies that an Automated Trading System team may not use its TAG 50 to enter manual orders. All manually entered orders must identify the Tag 50 of the specific person who entered the order.

The rule is effective October 8, 2012, pending all regulatory review periods.
