Connection problems

[Glenn]

G'day

The last few days I have had connection problems. I have tried restarting many times, but even when I'm connected it keeps dropping out. Here is an example of my log file:

27/05/2009 11:21:06 PM|1|2|Glenn: Primary connection=Connecting, Price feed=Connecting

27/05/2009 11:39:34 PM|1|2|Glenn: Primary connection=Connected, Price feed=ConnectionLost

I haven't changed anything hardware or software, and everything has worked perfectly for the last 6 months. I have run an internet speedtest and it seems ok. Currently the DOM is useless.

Any suggestions?

Hello Glenn,

Thank you for your post.

We realize that lost connections can be frustrating. A connection state between NinjaTrader and your broker/market data vendor is not dictated by NinjaTrader. The NinjaTrader application only reports the connection state as it is reported by the API you are connected through. NinjaTrader behaves like a radio receiver in that it receives signals from the connected server. If the signals are not coming through, the underlying broker/market data vendor API reports this to the NinjaTrader application which in turn reports this back to you. Once a loss of connection is reported, NinjaTrader or the underlying API wil continuously try to re-establish a connection.
Common reasons that contribute to connection stability are:

• ISP issues
• Hardware firewall changing IP addresses frequently
• Dynamic IP addresses changing frequently intraday. Usually this happens once a week buy you may want to check with your ISP. If they do change daily, requesting a static IP address may help.
• With Windows XP SP2, if you have more than 10 open TCPIP socket connections (10 programs making socket connections through the internet) Windows will randomly shut down some connections
• Broker/market data servers may be experiencing temporary downtime

-Try a direct connection if using a wireless router as well.
Please also try disabling or uninstalling any type of firwall, antivirus, or other protection type program as they can block the data feed coming into NinjaTrader.

?Thanks for the prompt reply

I've tried disabling the antivirus.
We're on XP SP3
Directly connected to the router

It's a zenfire connection

We've changed nothing harware or software for months.

How do we check Hardware firewall changing IP addresses?

I suggest to disable your firewall or contact your ISP as we are not connection experts, therefore cannot diagnose the connection issue.

You can also test at another location such as a free wireless area to rule out any PC issues.
