Interactive Brokers TWS connection not working

Thank you for your question.

IB connection does not provide automatic instruments downloading. In that case, from the app, you need to send searching requests via Connector.LookupSecurities. All found instruments will be provided via Connector.NewSecurity or Connector.LookupSecuritiyFinished events.

On our environment, the lesson shows AAPL instruments

Can you provide the link from where you have downloaded the materials?

PS We updated your support plus 1 week for the answer days reason.

I downloaded the materials from here, https://github.com/StockSharp/StockSharp/releases.

I'm not sure how to do the search request, in the video on minute 14 Yury clicks on the securities and starts to recieve information. I tried once more but got the same result, im just writing the code I see in the video.

here is my code

1. Did you unblock the archive before unzip?
2. Please try to add as reference to the project StockSharp.InteractiveBrokers.dll.

Yes I unblocked the zip. I added the reference and now it shows up but i still cant see anything not even if I search for securitys, I even started all over again and same result, i got an error when adding the toolbox im uploading a screenshot of the error and a video of the app

I am sorry but I cannot understand from where you downloaded the code on your video. Please use this direct link https://stocksharp.com/file/109596/Lesson_4_4_17_7z/ There code missed 2 points:

1. It does not have a reference on StockSharp.Configuration.Adapters - the reason why you do not any connectors on Settings window.
2. It does not have a lookup securities code on a connected event as I mentioned above: _connector.LookupSecurities(new Security() );

Please download materials from the link I've provided and try to run Lessons\lesson_01(simple_terminal)\01_Connect_and_get_security project.
