RE crashes on IQFeed disconnection.

I've recently started using IQFeed and find that I when it loses connection (due to being logged-in to elsewhere), RE will throw an exception and after clicking OK, it crashes without saving the LiveOpenPositions.xml which is very bad.

Is there a way to catch this exception or better still have it attempt to reconnect?

Can you post the stack trace of the exception?

To mitigate this, you can periodically call PositionManager.SaveOpenPositions() in your system to have a more recent version of LiveOpenPositions which you can use if RightEdge crashes.

Exception details are :

An existing connection was forcibly closed by the remote host
   at System.Net.Sockets.Socket.EndReceive(IAsyncResult asyncResult)

This will be fixed in the next build.

Hi Daniel,

Will the fix be in RE or in the IQFeed plugin?
If in the plugin, may I have the changes so I can patch mine?

The fix is in the IQFeed plugin.  The source code is included in the RightEdge samples so you can get the changes from there to apply to your copy of the plugin.

Hi Daniel,

If I take the IQFeed plugin code from b52 and compile it, will it run against b49?

Posted Thursday December 11 2014
You will need to make some minor changes to account for changes in the broker interface in build 52.

Just FYI I merged the new (b52) plugin code with mine (b49) and it has fixed the problem.
