I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

IQFeed Developer Support » no data Feb 7, 2018 01:22 PM (Total replies: 0)

I have been using a java project to get data from iqfeed for 3 years
Its suddenly stopped sending me data
the program connects and successfully creates the socket
no exception when writing the request to the socket
but now reading is always return null

Is this anything to do with firewalls?
I have recently switched to new ISP
