I keep getting this error message when I connect Ninjatrader to Interactive Brokers :
Ünable to subscribe to market data : Please assign an additional exchange to this instrument in the Instrument Manager (Name of instrument) Default
I get an error message for most of the instruments that are there in my portfolio, for some other instruments it seems to be working fine.
For example, CLF I am able to connect to market data. However for a stock like GMCR market data does not work.
Any help would be appreciated.
