Hi Mike

I have a question regarding otfeed example HistTick.java

How do you know that connection is actually initialized when you make the request?

Should you actually wait that OnLogin returns before you can actually call prepareRequest?

Thank you

IConnection connection = Connector.connect();

        try {
            IRequest request = connection.prepareRequest(command);
            request.submit();

            request.waitForCompletion();
        } finally {
            connection.shutdown();
            connection.waitForCompletion();
        }

Requests will be queued if connection process is not yet completed. So, no need to wait for onLogin() event. However, if login attempt fails, all requests will receive error completion status. In your listing, processing will block at "request.waitForCompletion()" waiting for the login and request completion.
