Hi,

I checked this on the continuous contract for the ES and Oil.

I noticed it in my data download application and checked it with the DTN supplied C# and Java samples to make sure its not a bug in my code.

Below is the output of a history lookup, I changed the code to display the line every time 09-18 17:00 appears in the incoming strings (as it arrives form the socket).

It did not happen with stocks symbols.

I tested 60 & 3600 seconds interval.

Checking the incoming data I can see that a large part of September 2014 is duplicated in the results (same dates, different values).

Another thing, when I tried to get data only from 2014-09-18, no data was duplicated. It occurs when I ask data for a longer time frame.

Please advise,

When I ask for the following there is no duplicates:

But if I just change the starting date to Sep-1 there are:

Hello Trender,

Thanks for the report, we are looking at the bug that created this issue now and will get a fix released asap. I will reply with an ETA once we know more.

Hi,
History download seem to be OK again (at least for @ES# there are no duplicates),
Can I assume the bug was fixed and it is safe to work with the data again?
Thanks
