To work with the iQFeed connector, you need to install the IQ Feed Client router on the computer, which can be installed on both the local computer and the remote one. Data exchange between the client application and the IQ Feed Client, as well as between the IQ Feed Client and the servers, is performed via the TCP/IP protocol.
To download the IQ Feed Client from the iQFeed site, you must first authorize using the password and login received from iQFeed.
After installing IQ Feed Client, it is recommended to restart the computer.
After installing IQ Feed Client, IQLink Launcher must be started.
In the IQLink Launcher window that opens, click Start IQLink.

The port numbers that are used by default for connection to the IQ Feed Client are specified in brackets. For client connections, the port numbers can be changed in the registry, for example, for Level1 on the following path: [HKEY_CURRENT_USER\SOFTWARE\DTN\IQFEED\Startup\Level1Port]. Port numbers for connecting to IQ servers can not be changed.
