Sorry did not understand that by touching you meant click inside. 
Yes I have touched several transactions. No there are not lots in
Trading:Crypto Currency:BTC-EUR  

Another issue that I just realized and is related to the functionality
of trading accounts, but maybe not the one that we are discussing here,
is the security/currency of the top level placeholder account Trading.
Shouldn't that be set in my base currency EUR? Strangely enough in my
case it's set in VOW which is a security I trade.
