@Christof+ thanks for the update. Germany is trickier for me to establish residence as I don't have friends/family there. I assume the choice to avoid Italy is either due to legislation (as per Australia) or market size. Not sure why they would avoid UK though. If I recall correctly they clear through Apex Clearing Corporation.
Just as an FYI for anyone interested, eOption requires an "offline" (paper forms) sign-up for non US residents (so plan ahead re time) and minimal account size is USD 25k (again, for non US residents).
