IIROC is responsible for regulating trading on all Canadian equity marketplaces to ensure compliance with the Universal Market Integrity Rules. The Surveillance Technology Enhancement Platform, known as STEP, gives IIROC the ability to conduct crossmarket surveillance that keeps pace with the dramatic growth in the speed and volume of trading in Canada’s equity markets. “In fulfilling our market surveillance responsibilities in a multi-market environment, we face the challenges of higher volumes, faster trading, new trading strategies and order types and more complex technologies,” said Susan Wolburgh Jenah, IIROC’s President and CEO. “The new STEP system consolidates regulatory feeds from all marketplaces, providing a centralized view of trading activity on the three exchanges and six Alternative Trading Systems currently operating in Canada. The STEP system will allow us to conduct more effective cross-market surveillance and analysis.” The STEP platform is directly managed and maintained by IIROC, giving IIROC more flexibility to respond more quickly and cost-effectively to changing market conditions and structure. STEP is a customized version of the SMARTS Integrity Platform, which has been developed for the Canadian market. SMARTS technology has been adapted and implemented by more than 40 exchanges and regulators worldwide. The new technology is adaptable and will allow for continuous development of new functionality. STEP can currently process up to 400 million trades, orders, quotes and cancellation messages per day and is scalable to meet the anticipated growth in the volume of trades and messages. IIROC continues to use the surveillance system licensed from TSX Inc. to generate singlemarket alerts for Toronto Stock Exchange and TSX Venture Exchange. All single-market alerts for the other regulated marketplaces in Canada are now handled by the STEP platform. IIROC currently monitors, on average, approximately 800,000 trades and 180 million messages daily.
