I am able to request historical lookup data just fine.

However, when using HIX and HDX history lookups to request specific bars back.... I frequently get slightly more or slightly fewer bars than I request.

I receive no errors back from iqfeed and I'm only requesting 100 days back of daily and 20 bars back of 5min and 2hr which should be available.... so I'm wondering what causes this?

Here are my requests :

Here is what I get in response... (I don't observe any pattern to why less data is sent sometimes, more others) :

Here is what I have been able to dig up on this issue.

First, the server logs indicate that the correct number of datapoints were returned for each of your requests yesterday.

When I make a comparable request today for each of your requests (I can't make the exact same request and get the same data returned), I see the correct number of results returned.

Looking at the results I get today and the results you've posted, I came up with the following results:

IBM86400 - your last datapoint is duplicated accounting for the extra datapoint.
QQQ86400 - your results are missing the 4/23 bar.

IBM300 - your results are missing the 15:25 bar
GOOG300 - your results are missing the 14:20 bar
QQQ300 - your results are missing the 13:20 bar

I have also verified that all server farms are returning these missing bars.

I can't explain these results but right now I'm inclined to think it has to be something within your software causing this since no one else is reporting similar issues.

yes it does seem to be random in terms of when and what bars are missed.

however this combined with the duplicate bar and your confirmation that your servers return this data probably means our buffer is occasionally being missed or read twice.

thanks for your help and analysis

yes it was a buffering problem, when a bar packet was split between two async packet buffers on windows and the request id happened to not be in the buffer.

was able to troubleshoot it quickly comparing the output from my software above to your tester tools. working now.

thanks again
