The Surveyor app is the first mobile tool to provide access to depth of book quotes for the U.S. equities markets. Users can access historical quotes, in any stock, on any date, at any time – down to the millisecond. With a database going back over two years, there are nearly one trillion data points available. In addition, Trillium’s expert trading staff will provide daily market insights in the app, showing users how historical quote data can improve their trading or market surveillance. “We believe in fair and open markets,” said Lee Maschler, Trillium’s founder. “By giving everyone access to this free big data research and analytics tool, Trillium is bringing more transparency to the US equities markets.” The app was developed as a collaboration between Trillium’s in-house team of trading professionals, and engineers, design firm Moment Design, and mobile app development firm Reflexions. The product incorporates technology built for mobile gaming to present smoothly scrolling graphs plotting billions of data points. “In today’s markets, you are at a disadvantage if you are not squeezing every last drop of usable information out of available market data,” said Michael Friedman, Trillium’s General Counsel and Chief Compliance Officer. “Our Surveyor platform is the tool to help you do that, and we are happy to now offer much of Surveyor’s functionality for free on the iPhone.” The Surveyor app is adapted from the enterprise version of the program, which is marketed to broker-dealers, trading firms, regulators, and asset managers for market surveillance and order routing optimization. Trillium launched the enterprise version of Surveyor in 2014 and later added a free web-browser version of the software. A beta version of the mobile app has been tested throughout the fall by leading traders and analysts. The final Surveyor app is now available on the App Store® or by visiting [www.TRLM.com/surveyor](http://www.TRLM.com/surveyor). **About Trillium** Trillium is a diversified financial services firm operating three business lines: a proprietary intraday equities trading group; an investment management group; and Trillium Labs, a trading technology development group and the creator of Surveyor, a post trade analytics and market surveillance tool designed to detect and eliminate market manipulation. Trillium is headquartered in New York City, with trading floors in Chicago, Miami and Princeton.  For additional information, please visit [www.TRLM.com](http://www.TRLM.com).
