The Securities and Exchange Commission on Wednesday launched a site on market structure to serve as a central location to share data and research. It’s a gold mine of information on how the market is trading. SEC Chief Mary Jo White touted the recent acquisition of a trade-information system called Midas, which the SEC bought from Tradeworx last year. The system allows participants to see much more information about what is trading than is normally available. What kind of data? Today most traders can see only price and volume. This information will likely be much more robust: you’ll be able to see total number of new orders, and the total number of cancellations….all broken down by exchange. See CNBC report here.
