Depends on how you define a trader
a) Someone who works for a brokerage & trades other peoples money (similar to the show in the 1990s)
b) Someone who day trades with their own money & makes their living this way?
c) Someone who makes strategic investments via a brokerage or discount brokerage in order to increase their wealth over a long period of time?
In my opinion c is an investor while b is a speculator (and either very lucky or extremely sharp)
-many a fool have lost big $ day trading and I do not believe it is sustainable over a long period of time, however that is my opinion and I have been wrong in the past (1998 I believe it was)
