Thanks for the Hashcard of 2010-07-13 45,7- looks like a beautiful place! MagicIan 19/07/10 21:38 (GMT)

You are welcome. I hope you were able to decypher my script, I wrote it on the train down to Zermatt, which proved to be a challenge :o) --Crox 21:00, 20 July 2010 (UTC)

Hi Crox. I've been building a small database of Dow openings. While checking the values I found that some of your Dow holidays are filled in with the closing value of the previous day. E.g. 2008-11-27, 2008-12-25, and several more following those. While I'm at it, how much discrepancy do you see on 2008-07-03? That's the only difference from Peeron/Google (back to the invention of the geohash) after fixing the more obvious stuff. Edit: Happy birthday, maybe, seeing the above. :-) --62.163.112.228 17:43, 5 April 2011 (EDT)

Hello 62.163.112.228, thanks for taking the time to report this and also for the birthday wishes :o)

For 2008-07-03, I've stored the following opening values:

 11215.9967544 from djindexes.com
 11216.00 from SunGard
 11216.00 from google.com/finance

If I remember correctly, Yahoo had a different value for that day, and I removed it manually. If you have a list of the other fixes you've done, or all historical Dow holidays, I'd be happy to have it. --Crox 16:30, 6 April 2011 (EDT)

Maybe I shouldn't have used the word database. It's more of a list of a few hundred Dow days, in an attempt to have a more accurate list than Yahoo's CSV (plotting nearby hashes to look for interesting ones is no fun when many are wrong). It currently runs from 2008-05-21 until now. I didn't keep the original data, but I think it only differs from your data on holidays, and definitely only from Peeron on 2008-07-03. You could diff against Peeron and see if it's all on holidays. I think checking for absent days in Yahoo's CSV also works.

Hmm, now that I look at my list, I think my first day — 2008-05-21, when the comic was posted — actually has the highest value. I guess geohashing is bad for the economy. --62.163.112.228 10:13, 7 April 2011 (EDT)
