"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan
"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. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"Everything is working great with the API. I love it." - Comment from Calvin
"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
"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
"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat
"I am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don

I added more examples including one with Expired Options:

Thank you,

Thank you so much Tim.
BTW guys, in the newest version 1.4.2 of IQFeed.CSharpApiClient, I've added a very simple way to retrieve those expired options and market symbols.

Code sample:
var lookupClient = LookupClientFactory.CreateNew();
var expiredOptions = lookupClient.Symbol.GetAllExpiredOptions()
.Where(x => x.EquityOption.Expiration >= DateTime.Now.AddMonths(-6)).ToList();

var marketSymbols = lookupClient.Symbol.GetAllMarketSymbols().ToList();

This will take some time the first time but the code will reuse the cached file and check for new update every time.

Hope this helps.
Mathieu


Excellent news Tim, I'm in the process of adding support for this file in the IQFeed.CSharpiApiClient wrapper. Will be very easy to use. Ill post back on this thread once available.

Mathieu


Thank you Tim,
I think we should keep the file option.. For me this is a more convenient way to retrieve expired options. Can you expose to us the long term goal get them at the end?

Thank you.
Mathieu


Guys, dont hesitate to open an issue on GitHub rather than posting on this site.... I think its more related to the project itself.

Will always happy to help you out with that.
Mathieu


Hi T,

Well, if you wish to see the result as a data table, I suggest you to use the Raw facade, i.e. lookupClient.Historical.Raw.ReqHistoryTickDatapointsAsync method and then open up the return filename in Excel as a CSV file.

The reason you it in that format its because I didnt override the ToString in the TickMessage class.

Please dont forget to star the project on github and you can also ask question over there!

Thank you,
Mathieu

Split.string is the way to go:

Well, I'm still skeptical about the real performance benefit of not using .Split. I'll do some performance tests to conclude on this.


Hello Tim,

Any updates regarding this request?

Thank you,
Mathieu
