Ninjattrader platform

Will you be adding NinjaTrader as a platform? I have accounts with TD Ameritrade and this might enable auto trading with them and other brokers.

Anyone been successful with this?

Maybe I misunderstood your question, but NinjaTrader is available on C2.
I’m using it from June 2019 and all work well.
The only problem I encountered is that when starting the C2 transmitter on two NT8, it inevitably leads to the shutdown of one of them, which does not allow running on different strategies on different computers at the same time.
