active trading and trading in general is not investment.
wealth and investment management, however, allows for certain trades which include a periodic e.g. quarterly re balance activity to be inline with the underlying investment thesis of that venture.
That being said, its not specified further in that context here, but other countries from europe do have some guidance on how/where the lines are being drawn.
Could be they are generous︀ and consider only algo trading as trading business and a few weekly trades still falling︁ into the investment category, but idk that and it seems theres no one out there︂ being able to tell.
