There is a problem in the Yahoo feed for the Dow 30. This is true for ^SPX, INDU and SPX (the symbols that I know of). I am looking at making an amended version of the screen scraping routine that the PocketSense quotes.py can fall back on if the main
method does not work for a symbol.
It is also possible that it will get fixed in the feed, but for now, I suggest you enter the value manually.
http://finance.yahoo.com/d/quotes.csv?s=^DJI&f=nl1d1t1pp2 is the primary link that PocketSense uses to try to fetch the quote. This returns a CSV file normally, but it delivers an
error message for the Dow 30 symbols.
