In my professionally formative years I probably spent as
much time looking for and organizing market data as I did analyzing them via
Excel spreadsheets. So, in the spirit of the holiday season (not to mention my
own self-interest in promoting the web site), I now offer free daily updated
CSV files of the following indices: S&P 500, DJIA, NYSE, Nasdaq 100,
Russell 200, and Amex. Each file offers the following data for its
corresponding index: open, high, low, close, % change, total volume, advancing
volume, declining volume, advance decline volume difference, advancing issues,
declining issues, unchanged issues, advance decline issues difference, 52 week
new highs, 52 week new lows, and 52 week new high new low difference:

Each file is updated by 6:00PM Central Time each trading
day.
