You inquired regarding a client interface for MarketStream's program (USMMAKER.EXE) that serves up L2 data. I have gleaned the following information from the UMDS help-file, by loading the interface, and from MarketStream's web site. 1. There is a Dynamic Data Exchange (DDE) interface for the UMDS. It is a server application, called UsDDE, that allows client applications to access real-time data. It runs on top of the UMDS, filters data which is cached by the UMDS , and serves it up via the interface. It allows RT data to be piped into, for example, an Excel spreadsheet by entering a formula in the cell that receives the data (example: =USDDE\|QUOTE!'symbol;field', where symbol is a stock symbol, and field is OPEN, LAST, etc.) UsDDE provides the most recent quote data once/second, i.e. it filters time & sales. 2. Unfortunately I cannot tell if the DDE interface works with the L2 version (USMMAKER.EXE) of the UMDS. That question would have to be directed to MarketStream. 3. There is an SDK available for programmers who want to develop clients that use the UMDS. From MarketStream's web site: "The Universal Market Data Server SDK (Software Development Kit) contains everything a C/C++, Visual Basic 5.0 or Delphi programmer needs to develop the next generation of 32bit Windows applications using the Universal Market Data Server. The SDK includes the High Speed API and DDE interface specifications, sample code, a special version of the server useful for testing your application and other files. In also comes with a single use license of the full server and a Market Data CD." 4. For more information, go to MarketStream's web site, <http://www.uniserv.com>. You can download a free version of UMDS version 2.0. The self-expanding file will have help-files with further information. Included will be a setup file for the UsDDE client interface. You can also download a free copy of the L2 version of the UMDS (USMMAKER.EXE). 5. None of the above works without a subscription to one of MarketStream's supported data vendors. I have no practical experience with the DDE interface, beyond downloading it and experimenting with it. Hope this helps.
