"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Hello MattR, are you a current API Customer? If so, our Developer Support can work with you on troubleshooting the connection issues that you are having. If you are not an API Customer then to be able to connect your tool directly to IQFeed you will require an API License to do so. You can sign up for the API through this site:

Hi Matt, The default ports are all set in your registry. You can change them in the HKCU\Software\DTN\IQFeed\Startup folder. All of the default port settings are held there.
