I believe what you're saying is, C2 trades will be entered through this soon-to-be-announced front-end. That's great. I'm also wondering, however, if it is possible to use the IB API to send trades entered through IB's TWS -- regardless of the front-end employed -- to C2. Thanks again...
As far as I know there is no product / interface available that does that. Of course, you are encouraged to write your own!
