I think the reason we have not had an issue with this so far is because most third party developers open these ports and then do not close them till the app shuts down. But as you said this is not a clean way of doing things. This has been brought to the notice of IQFeed developers and you can expect a fix or a new release soon.

Do you see this behaviour with the history socket client sample app too. I am not seeing any of this on my end. I do see the 5009 being opened but it gets closed when the app calls removeclientapp.

Ryan,
We do not limit symbols to 255. However I am not ruling out the possibility that all the symbols are not being returned. I will be able to verify this after some testing on my end. I was able to verify that the nears option is currently inactive. We are working to fix this.

There are a couple of interface changes.

1) The TCP request format has changed for Histroy, News, Option chain lookup and Symbol lookup. The delimiting characters and the terminating characters have changed.

2) IQFeedY does not receive a connect status. The connect status is indicated by "S,SERVER CONNECTED" in the system message.
