Yahoo! Finance feeds are pain in the ass.
Google Finance API seems OK but don't know why I can't retrieve stock quotes information for Dow Johnes, NASDAQ, S&P...
Works perfect with company quotes like YHOO, MSFT but don't gets full data for stock indexes.
There is an article at YQL blog on how to get this data from Open tables with YQL, but that table is missing in the list.
Can anybody recommend any good API, web service or a feed?
Best answer + vote up guaranteed.
Yahoo provides a free API via http. You can get real-time informations & historical data in csv format.
For example to get the S&P historical data (^GSPC):
http://ichart.finance.yahoo.com/table.csv?s=^GSPC&ignore=.csv
or Dow Jones (^DJI):
http://ichart.finance.yahoo.com/table.csv?s=^DJI&ignore=.csv
