I haven't been able to connect to IQFeed, with SierraChart, since July 14, 2017. I believe I have a Firewall issue with BitDefender, but I want to confirm that there are no issues with IQFeed's servers. Are you experiencing any data transmission issues?

Thanks.

I have reproduced my most recent SierraChart log below:
