DTN.IQ Client Software Support » multiple IQFeed accounts Nov 11, 2012 08:17 AM (Total replies: 2)


my computers are set up with my own IQFeed account. Tomorrow I need to run somebody else's account on 1 of my computers. However, I do not seem to be able to figure out how I can enter his username and password. The IQFeed connect window where I put my username and password pops up and disappears again so I can't enter another user account. I see in the registry where this information is stored but I guess there is a simple way to do this.

So, how do I set up for instance two quick launches so I can chose which IQFeed account I want to run,


Data and Content Support » +CL# data Aug 26, 2011 04:54 AM (Total replies: 2)

issue has been resolved. There was a problem with the +CL# and QCL# tickers. Strange no one seems to have noticed

Data and Content Support » +CL# data Aug 19, 2011 02:26 AM (Total replies: 2)

it is strange that no-one else noticed that the tickers +CL# and QCL# are in error. The EOD databse is correct but the intraday database is not. The wrong contracts are merged and therefor completely useless. Spoke with support about this but I think they only look at the EOD database and that looks ok. The intraday database is what is wrong, although the last 3 months, June, July and August are right. 2008, 2009, 2010 are wrong

I contacted IQFeed with a problem but they say it is non-existent.

since about a week I started a new database in Amibroker and backfilled +CL#. The data is however different than databases I made earlier. Not all data but a lot. It seems the contracts used to put in this continues string of data are different. Or: the way contracts are merged is different.

This is a chart of the old database:

This of the new:

the databases are created the same, using a 5 minute timeframe.
a) From 5/18/2011 up until today the data are the same.
b) Then I have a difference from 4/27/2011 to 5/17/2011.
c) Then the data are the same from 4/15/2011 to 4/26/1011
d) a difference between 3/29/2011 and 4/14/2011


Next I show data at 4/26 and 4/27. In the old database I have the correct contracts displayed, correct meaning the most active contract. In the new database I have correct data on 4/26 but some other contract on 4/27. Both price and volume are different. It looks like next months contract at that time.

The old database displaying correct data on both 4/26 and 4/27:

The new database displaying correct data on 4/26 but incorrect on 4/27:

can someone confirm this?

thanks, Ed
