I'm working with a 500 symbol limit, but there's no way a single computer will handle all the processing of various strategies. They have always been run from different machines in the office. Since I can't load the Connection Manager more than once, I'm trying to just use 1 connection in the house and let a few trading apps connect through it.
I tried this without success:

adminSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPAddress ip = IPAddress.Parse("192.168.1.101");
RegistryKey key = Registry.CurrentUser.OpenSubKey("Software\\DTN\\IQFeed\\Startup");
int port = Convert.ToInt32(key.GetValue("AdminPort", "9300").ToString());
IPEndPoint iq_serv= new IPEndPoint(ip, port);
adminSocket.Connect(iq_serv);

The connection manager is running, but it refuses the connection. Does it refuse connections from anything but localhost?

I understand the potential for abuse, but could this be opened up to at least 192.168.x.x addresses so we can actually use our symbol limit?

If we have a machine that runs a strategy on only 20 or 30 symbols, do we need to pay for another login?

Thanks!
Eric

Due to restrictions against redistribution of data, IQConnect is required to restrict connections to the local machine. We (Telvent DTN) have products that are better designed for redistribution but as you can imagine, they are far more expensive than IQFeed.

It is certainly possible to process the datafeed for 500 symbols on a single machine without problems. Of course I can't make any guesses as to the processing required for your strategies.

It sounds like you will need to either use a single machine to process the feed or purchase multiple logins to distribute the workload over multiple machines.
