Re: No response from scanner


 

The scanner you describe is pretty basic and works just fine within our framework (based on the Java API) as well as with the two sample API clients IBKR ships with the API:
  • The C# client IBSampleApp.exe for Windows
  • The Java based client ApiDemo.jar that works on all operating systems

It takes about 500ms for TWS to send the first block of 20 results right after subscription, and subsequent updates get sent approximately every 30 seconds after that.

Why don't you try and get a "second opinion" from one of the demo clients. That way, you'd know whether the issue is with your TWS/IBGW or your own client.
