When I finally get up and running with FXCM... I was planning to use the FXCM web version only. It's lighter-weight on the system and I don't intend on really needing heavy-duty charting for the platform that runs Zorro. We'll have to wait for JCL to chime in, but it "seems possible" that both the Trade Station app and Zorro "could" be accessing the API in the same way.
