Erroneous market data

[Sleeping Troll]

We have been going crazy trying to figure out why our indicators are all out of whack, particularly one that displays the High, Low and Open for the Year, Month, Week, and Day... Imagine our chagrin when we discovered that our last historical reload from Zen-fire provided erroneous data! Check out this link and find the 5/7 drop on the chart...

http://www.google.com/finance?q=INDEXSP:.INX

notice that it indicates that it occured on 5/6! our data from Zen-fire indicates it happened on 5/7 but at 10:30 AM which is not as wrong, but wrong is wrong. also the yearly open price is wrong and who knows what else! We have subsequently found erroneous data all over the web! Do you all happen to know what is up?

Also the Low price on the day of the "Dive" is different on our Zen fire data and google and neither reflect the actual low price!

Sleeping Troll, this is likely related to a data server outage for 65 users on this day (May 6th), which resulted in data not being recorded as expected unfortunately.

By 65 users, you mean NTwas one of the 65?

Hello Sleeping Troll,

Please pardon the typo, this line should have read " Sleeping Troll, this is likely related to a data server outage for 6.5 users on this day (May 6th), which resulted in data not being recorded as expected unfortunately.
