I am looking for a relatively easy way to create and maintain a database of all Nasdaq and NYSE stocks from which I will build other tools for my trading. One important feature is that the data I get also group these stocks by sector (sometimes the data I see on yahoo and google are not the best for determining if stocks are in the same sector). And that these lists are updated as new stocks come and go. Currently I have a program called MLDownloader (http://www.trading-tools.com/) This has stocks sorted by sector that you can export to a CSV format. I am thinking of writing something to programmatically push this to a SQL database or something. Is there an easier way to do this? Are there any better, relatively low cost or free software solutions, or subscriptions to some service that would provide convenient access to such a database? regards
