I must have not communicated clear enough: I know all too well CFD and Forex are different instruments, and that they require separate datafeeds. In my TWS both work as expected, so I think it's safe to say the subscription for both of them is active and feeds my TWS-platform with data. I do NOT get a live feed however when I enter the exact same instrument definitions in MotiveWave (I tried EURAUD, EUR.AUD, a simple EUR but denominated in AUD, ... like you suggested before)
As a long-term SDK-user and custom-coder for MW, I can benefit from a very healthy relationship with their Dev-team, so I will contact MW as well in parallel, but I also expect answers from IB:
* what is the correct way to 'define' an instrument on the SMART-exchange for use with the API (because that is after all what MW -or any other third-party platform for that matter- does) ?
* Given the fact that the 'quote details'-trick from a couple of posts ago is apparently not working: Where can I find the correct definition for CFD's (or any other instrument) on the TWS-platform ?
* I am a programmer / sysadmin myself, so not afraid of log-files and debugging

: where can I look 'under the hood' of TWS, so I can figure out what third-party calls are being made and where issues exist ? Is there a debug-window of sorts ? A log-file for incoming API-calls ? An error-log ? ... ?
