Hi guys,

I just started with IQFeed. I am trying to interface with Matlab. I have the datafeed toolbox in Matlab which has IQFeed support. I also downloaded the client. However when I run the iqf function to connect I get the following error:


Error using iqf (line 53)
Message: Could not load file or assembly 'file:///C:\Program Files (x86)\DTN\IQFeed\Example
Apps\Interop.DTNIQFeedCOMLib.dll' or one of its dependencies. The module was expected to contain
an assembly manifest.
Source: mscorlib
HelpLink:


I think it is looking for some example apps that are not in the client install. Could someone point me in the right direction or perhaps PM me ( :) ) the dll file? When I contacted Matlab, they said it was an issue with IQFeed, and not them.

Thanks!!!

Hi,

I also am having problems connecting Matlab to IQFeed. Is there a solution to this problem?

Matlab HELP refers to "Look for Interop.DTNIQFeedCOMLib.dll in the installation directory of IQFEED" which I cannot find.

Many Thanks,

L.
