All gambling games have specified beginnings, middles, and
endings, based on a sequence of events that determine the outcome
of the game. Once you decide you are going to participate, you can't
change your mind—you're in for the duration. That's not true of trading.
In trading, prices are in constant motion, nothing begins until
you decide it should, it lasts as long as you want, and it doesn't enduntil you want it to be over.
