"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

Hello boze man,

I would be glad to help, but am having a hard time finding the same thing in the data here. Are you saying that a 12:42:00 eastern US time trade for @NQ# (for example) showed up at 14:36:00 on Dec. 21, 2012? I am not seeing that in the data here, but if you have a tick id or any other additional information, that will help.

Or perhaps, I misunderstand? - let us know. Thanks.

I should add that, if you have a more recent example, it will be easier to check on because tick data is limited to 8 calendar days during market hours. Thanks.

thanks for the reply...

actually it is the opposite...the 12-21-2012 14:36 MST timestamp was being inserted at 12:42 MST 12-21-2012...not sure if it tick etc

i was able to delete and re-download the data successfully but only after numerous attempts...

thanks

there may be other markets with out of order timestamps...at one point i think @es or @es#c had the same issue but do not see it now

they all seemed to be occuring at 12:42MST

thanks again

Hello again,

There was a connectivity issue on December 21st that caused a gap in the history for these (and other) symbols. This data was inserted after the fact and there is an issue with some of the backfilled data. We are currently investigating a fix for this problem and will reload the corrected data when it is available. I will be back here with any updates.

Hello Boze man,

I am told that this issue has been repaired, but I am not able to verify until after the market close. Thank you again for letting us know.
