"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

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?

Thanks,
Steve

I don't think there's a C#/sockets example in the SDK, but this old post should get you started: http://forums.dtnma.com/index.cfm?page=topic&topicID=284

For some advanced code that works as an event driver, see https://sourceforge.net/projects/ousq/, or http://www.oneunified.net/blog/Trading/SmartQuant/Articles/index.blog. 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,
Mathieu

Mathieu,

First of all Thank you for your open source project.

Your code looks really good and I will probably add more to it. I downloaded your code.

For some reason, the .Net 2.0 Standard dependency is not detected.

On Compile i get the following error. I am using VS 2017 Community Edition. I have .Net 4.6.1 installed

Can you please guide me what is the easies way to get the code to compile. I was able to play with the examples posted by DTN - however yours is high performance IMO.

Error on Build
