I'm trying to run the Ninja Trader C# Sample Application with NT version 7.0.1000.2. However, I get the following error:
"Unable to connect to NinjaTrader (127.0.0.1/36973). Please make sure NinjaTrader is running: Object reference not set to an instance of an Object."
Any suggestions? AT interface under File menu is checked. I can connect to the same port using external data feed connection with Tradestation.
Thanks.
