Which mode are you using? Replay/live? If live - which feeds are you connected to?

What is the last build where you didn't have such issue?

Could you please specify which line exactly throws an exception now? I see that you call some "init" function, which is presumably not part of API, that's why I'm asking. Do you observe the same behavior with demo modules? Does it happen reliably (i.e. on every start) or randomly? Could you share a ...

Hi. If you are using core api (which you seem to be) - how is your ValuesFormatter defined? If you can share a short example which shows the issue - would be great.

Are you sure the icon that you are removing is actually the same one you added? I assume your code sample is incomplete (uninitialized variable, freshly created canvas with no icons has icon removed from it), so if possible please provide a more complete example.

Hi. DxFeed API is not public. Yes, documentation is open, but in order to get data from it you need to sign an agreement directly with them. We are explicitly forbidden from re-exporting DxFeed data.

Are you asking if there is a way to configure R Trader to pass data faster? I am not aware of any way to do that. In cases where R Trader is a bottleneck (which it might or might not be - e.g. if your network is a bottleneck, then having plugin mode on or off does not matter) connecting directly sho...

Red text means ingested data is delayed already. When bookmap itself does not keep up (case 3) symptoms typically look like bookmap postponing recentering (which can look like freezing) as a last effort to catch up. While it's possible to delay data ingest by in-process issues, it's not something we...

Not really. Screen Space Painter extension (same as some other extensions) can be used from both Simplified and Core API in a similar way.

It's not larger, it's a development snapshot. x.x.1.x builds are development builds, those can't be directly compared to release ones (x.x.0.x)

Also make sure to switch repository from http://maven.bookmap.com/maven2/develop/ to http://maven.bookmap.com/maven2/releases/ to use release branch.
