thanks a lot Jay, that worked
hi,
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,
thanks.
issue has been resolved. There was a problem with the +CL# and QCL# tickers. Strange no one seems to have noticed
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
in my opinion look here:
http://iqfeed.net/symbolguide/index.cfm?symbolguide=guide&displayaction=support§ion=guide&web=iqfeed&guide=commod&web=IQFeed&symbolguide=guide&displayaction=support§ion=guide&type=sgx
you could use: NN#
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: http://3.bp.blogspot.com/-WBhOQy-T7dM/TkIwv3J37DI/AAAAAAAAAIE/7B-mATaBPI4/s1600/all_old.png
This of the new: http://3.bp.blogspot.com/-4eQjZcRn6oM/TkIw13bTzxI/AAAAAAAAAIM/gg4MDRqBk4Y/s1600/all_new.png
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
etc.
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: http://4.bp.blogspot.com/--iFIUtvXvMw/TkIz0Sye6NI/AAAAAAAAAIU/-YNLrOfNs3I/s1600/2_old.png
The new database displaying correct data on 4/26 but incorrect on 4/27: http://1.bp.blogspot.com/-Kql1yNC9bfg/TkIz4KA0OtI/AAAAAAAAAIc/Nfw8Y6Z1jS8/s1600/2_new.png
can someone confirm this?
thanks, Ed
