Frequent IB Connection Lost Issues

[kcsystemtrader]

Yesterday and today I've had several events (about 4 per day) during the trading session where my connection to IB has been lost. Wondering if anyone else has experienced similar issues or if anyone has also witnessed an increased frequency of this these ConnectionLost events.

I have changed computers and ISP's the strategy is running on (although both should be of equivalent quality and bandwidth) so this is probably the problem (even though ISP and computer are still high speed/high performance setups), but I still want to rule out the possibility that the problem is on IB's end and not mine.

If it is my new setup, do you all think the problem is most likely the ISP, or could it somehow be related to RAM or processor speeds on the new CPU? Thanks,

kc

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

Hi Guys,
Just wanted to report that I too get these disconnects a couple of times a day with IB. I am using windows xp and have nothing else running. Also, I have been using IB with other software such as Amibroker, Wealthlab and .Net programs of my own creation and have never experienced such drops.

Followup

To followup, my issues were router/ISP related...nothing to do with NT. I had to restart my router and then it started working fine.
