The Intermarket Surveillance Group / ISG is an organization made up of securities exchanges, market centers and SROs. The purpose of the Intermarket Surveillance Group is to detect fraudulent and manipulative market activity. Members of the ISG work together to develop programs and procedures designed to identify potential fraudulent activity and to share their findings with the other members. If a member of the ISG such as FINRA or the SEC requests information from a broker dealer during the course of an investigation the broker dealer will submit the requested trade data for the period in question by using the Electronic Blue Sheets / EBS. The Electronic Blue Sheets will detail all trade data for the member firm’s proprietary accounts as well as trade data for customer accounts.
