IQFeed Developer Support » multiple client programs connected to iqfeed Jan 22, 2014 08:03 PM (Total replies: 12)

To remove Neoticker from the equation I was able to reproduce the issue with the Tradelink connector by simply starting the iqfeed client from the iqlink launcher then trying to connect with the Tradelink connector.

So I think somehow it is not detecting that the iqfeed client is already logged in.

if the problem is in fact Neoticker, then i'm guessing i'd have issues in the case where I turn on the Tradelink connector before Neoticker.
So far doing this seems to allow both to run fine together with the IQFeed client.

My hunch, and it is just that, is that the Tradelink connector is trying to load IQFeed client again which poses a problem since it's already loaded and authenticated.

I will ask Pracplay support to weight in.

However I'm working with them directly, and they also have a login on the forum. I can have them reply to this thread if that's better.

can Tradelink/Pracplay post here to get support for what to do in their code?
or is there a different channel for this?

thanks for your reply

I am trying to have two programs that both connect to IQFeed at the same time.
One is Neoticker, the other is Pracplay/Tradelink that has a iqfeed connector built

When I try to connect with Tradelink and Neoticker is already connected, I cannot connect.
However when I do the reverse order, Neoticker can connect fine and they are both pulling data.

I assume therefore the problem is with the Tradelink connector not handling the fact that Neoticker already has loaded iqfeed and is logged in.

We get an error in the Tradelink connector log as such:
 235530: l1 error: The IAsyncResult object was not returned from the corresponding asynchronous method on this class.
Parameter name: asyncResult at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult, SocketError& errorCode)
at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult)
at IQFeedBroker.IQFeedHelper.OnReceiveData(IAsyncResult result)

Can you advise how to allow for supporting existing connections in the code?


actually I no longer need this as both programs seem to support the latest.

thanks for your reply though.



I need to be able to run multiple versions of the client on one machine due to one program I use requiring an older version and another requiring version 5.

Is there anyway to allow this? Currently when I try to install 5 it tries to remove the older version.
