Talk:Dow Jones Industrial Average

This phrase "Opening of the Dow Jones" seems to be used very loosely. Could it be made somewhat more explicit? Whose figure is used? I complain because [1] effectively says that there's no such thing as the "opening" of the Dow - instead it's the NYSE that opens, and the Dow is just computed from that. For the time calculation, how about less ambiguity like referring directly to 9:30am New York Time (if that's correct), or something? 130.194.80.156 08:32, 20 June 2008 (UTC)

Nearly every finance-page lists the value for the DOW's "Opening". No matter how it is defined internally, that's simply the value used for the calculation. --Hermann 22:58, 3 July 2008 (UTC)

Nearly every finance-page lists a different DJ opening value. Channel N24's teletextpage, which you added to this page for manual use, only shows one decimal place, as does channel Pro7. If I use that value in my offline calculator, I get coordinates which are different from irc.peeron.com. Channel n-tv shows 2 decimal places, but yesterday (2008-09-17) they were slightly different from irc.peeron.com, leading to very different coordinates. This either means that there are multiple correct coordinates for every day (which I think is not a good idea) or that only the official implementation's coordinates (i.e. the finance.google.com opening value, which seems to be identical to finance.yahoo.com's) may be used.
