Hello Andrew,

Added 2 additional examples for Python and one is related to what you were asking for.
Please have a look to Streaming level 1 example.

Hello Andrew,

Feel free to create an issue https://github.com/mathpaquette/IQFeed.CSharpApiClient/issues if you need more support.

Thanks,
Math


For the benefit of everyone and for those who want to fully enjoy the true speed of IQFeed without too much compromise, IQFeed.CSharpApiClient is now offering support for Python in most cases. I received a lot of comments how the client is superior in term of performance compared to existing Python implementation.

Have a look and feel free to reply for any concerns.

IQFeed Developer Support » Incorrect Data for Level 1 Tick by Tick Oct 6, 2019 03:43 PM (Total replies: 1)

Did you check https://github.com/mathpaquette/IQFeed.CSharpApiClient
I already provided a lot of examples to do what you try to achieve.

Thanks,
Mathieu


I added more examples including one with Expired Options:
https://github.com/mathpaquette/IQFeed.CSharpApiClient/tree/master/src/IQFeed.CSharpApiClient.Examples

Thank you,
Mathieu


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
