The NASdaq Trade And Quote database provides intraday trades and quotes for all Nasdaq stocks. Nastraq stands for North American Securities Tracking and Quantifying system. It is a sophisticated software application that can build and update an Access-compatible database of the closing price histories of all securities traded on the NASDAQ, AMEX, NYSE and OTCBB markets (strictly those whose closing price histories are available on the NASDAQ web site). It also includes the histories of some 14 other indexes. Currently the database contains 5,004 NASDAQ, 1,000 AMEX, 3,614 NYSE, and 4693 OTCBB securities or indexes all with full history. This means an historical database (up to 96 months) of all significant stocks traded worldwide (because non-US securities are traded in the US as American Depository Receipts). The database can be put on any modern home PC and comes with an extensive suite of pre-configured analysis software.
The Nastraq program makes it easier for you to get better and more detailed information about quotes and trades on the NASDAQ Stock Market. The data is stored on CD-ROM in MS Access format. This program provides an easy interface to retrieve the particular stocks you want for whatever date range you have available. For detailed data information, go to documentation or the vendor site.
