Quote from Mr J:
Some of you clearly don't know the definition of gambling: having a stake on an event with an uncertain outcome. All trading is gambling unless the is no risk involved.
Your definition is deficient... you must also conclude, "where the odds are fixed and against you with no possibility of making the odds in your favor". (That is, the payoff is ALWAYS less than the probability of the event... the difference is the "house edge".)
By your [deficient] definition, "crossing the street" would be a gamble.
In spite of trading's (1) risk of loss and (2) uncertainty of outcome, I do NOT equate trading with gambling... as you can make the odds in YOUR favor in trading by learned behavior.
