"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues.

Brand new to IQFEED as of today. I would like like to get streaming tick data using sockets. Could someone point me in the right direction as to how to get started? Ideally, it would be great if there was a simple sample app written in C# that did this. Also, is there a document that details this?

I don't think there's a C#/sockets example in the SDK, but this old post should get you started:

For some advanced code that works as an event driver, see, or The code can be downloaded via the svn browser at SourceForge. The code package was built for SmartQuant, but is modularized enough that bits can be used elsewhere.

Hello @stargrazer,

Please have a look at this project. This library supports IQFeed 5.2. Fully written in C# in a highly efficient way. The code is production ready with unit and integration tests.

Feedbacks are welcome.

Thank you,
