This has been lifted directly from the CME's regulations:
" ATS (Automated Trading System)
An ATS is an electronic system or computer software that is programmed to generate and route orders into CME Globex without a specific human action involved in sending or verifying the orders. This type of system is often referred to as a black box. An ATS operator is a person or persons that operate, administer and/or monitor the ATS. Typically, people in the operator role initiate or disable particular algorithms or strategies, or adjust the parameters of the automated program.
An ATS that does not require an individual to initiate or manually confirm the creation of a specific instruction must be assigned, and must transmit into CME Globex, a unique TAG 50 that identifies the person who operates, administers and/or monitors the ATS. If the ATS operator is responsible for multiple trading models, algorithms, programs, or systems which trade the same product, and which potentially could trade opposite one another, then each model, algorithm, program or system must be assigned a unique TAG 50. Any deviation from this requirement must be approved by CME Market Regulation before being implemented.
Some trading entities have assigned groups of individuals that work together to operate and monitor ATSs. For example, a firm may have one person who adjusts pricing parameters, but others who continuously monitor positions or risk and make decisions as to trading size. In these team situations, the individuals may use a single TAG 50 subject to the approval of CME Market Regulation. When registration is required, these team TAG 50s must be properly registered in EFS, as discussed below.
Team TAG 50s may only be used in true team situations. Entities may not bundle all their ATS operators under one TAG 50 if those operators primarily work independently or at different times of the day.
ATS TAG 50 Registration Requirements
CME requires clearing members to register all ATS TAG 50s in EFS if they represent individual members or employees of a member, a clearing member, a corporate member, or a party receiving preferential clearing fees as a result of participating in any special program offered by CME. These membership categories and programs include CME Rule 106.H. (Corporate Member Firm Transfers) members, CME Rule 106.I. (Related Party Employee Transfers) members, CME Rule 106.R. (Electronic Corporate Member Transfers) members (ECMs), CME Rule 106.S. (Family of Funds Transfers) members, Asian Incentive Program (AIP) participants, Emerging Market Partner Program (EMPP) participants, European Incentive Program (EIP) participants, eFX Bank Incentive Program (BIP) participants, CTA/Hedge Fund Pilot Program participants, and the New Trader Program.
The clearing firm must associate each ATS TAG 50 with the name of the person who is directly responsible for controlling the trading of the ATS, and must select the ATS attribute on the registration screen within EFS to indicate that the TAG 50 represents an ATS. Each ATS operator must provide accurate and up-to-date information to their clearing firm concerning ATS TAG 50s in accordance with the requirements described above. The TAG 50 that is registered in EFS must exactly match the TAG 50 that is submitted on CME Globex orders entered through iLink connections. "
