connection lost

[wuhui6]

Hi Support,

I'm constantly facing connection lost problem. sometimes it's primary connection lost, sometimes it's price feed connection lost. i'm using the CQG demo account with ninjatrader brokerage, this happens usually when the market gets busy, e.g EU market open, US market open, data releases.

is this because CQG has to kick some demo function off when market gets busy? or it;s purely due to a connection problem with my ISP? how can I resolve the problem?

thanks

Hello wuhui6,

Thanks for writing in.

CQG does not kick people off of the demo where there is high volatility.

The first thing I would recommend doing is exiting NinjaTrader and restarting your modem/router.

If you have an antivirus/firewall installed you will want to add NinjaTrader to it's exceptions list.

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 will 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 but you may want to check with your ISP. If they do change daily, requesting a static IP address may help.
Broker/market data servers may be experiencing temporary downtime.
