Expert traders would like to short term trading, they are mostly comfortable to day trading i know some people, long term trading boring for them, they want to make profits in daily, but even expert traders can not make profits in consistently it's impossible, because they don't know what happen in the next after bought a token.
These people aim to be in profit by having more good positions than the bad ones. The difference is in PNL, of course.
Trader is not the one who is getting profits all the time, it is the one who is getting them by the end of his sessions.
