I closed my account in CT. I have a IB account and even if CT was more expensive, I didn’t want to have all the funds in the same place but the prices and several other things made me take the decision.
Also, honestly, having 2 or 3 brokers is just a pain… different logins, systems, interfaces, fees, taxes…uff…
Thanks everyone for the valuable messages. I am probably going to check if Vanguard can provide me the information.
Regarding CT vs IB: I am still struggling with myself to overcome this (irrational?) fear of moving to an international brocker. But I am working on it 
Swissquote is a little cheaper than CT and is more professional. They have an offices in Gland and lounges in Zurich and Bern.
