Unable to coonect to NinjaTrader
Hello,
I wrote a java programm that connects to NinjaTrader using the DLL. It works fine on my developing laptop (windows xp). But when I run the programm on my trading computer (windows vista) I got the following error "Unable to connect to NinjaTrader (localhost/36973). Please make sure NinjaTrader is running" The "AT Interface" in file menu is on and a connection to "Simulated Data Feed" is established. Do you have an idea? Thanks. Regards, Markus |

Hello,
Can you connect via file>connect? Have you tried turning off your ATI and simulated data feed: File>disconnect > simulated data feed File>AT interface

Hello,
yes, I can connect via file>connect. I turned on/off data feed and ATI several times. But the connection problem is still there. Might that be a problem of windows vista or Norton Internet Security 2010? What else can I do? Thanks. Regards, Markus |

Markus,
It could be firewall/antivirus. Can you please try turning those off temporarily?

Hello,
I solved the problem. I need to use the IP 127.0.0.1 instead of localhost to get a connection to NinjaTrader. Now it works fine. Regards, Markus |

Hello,
I am having the exact same problem. However, I am connecting through the 127.0.0.1 and am still getting the same error message. Are there any other solutions? Thanks in advance |
