Quote from kut2k2:
You're new so maybe you're not familiar with the trading definition of gambling: taking unjustified risks.
Casino craps, roulette, slots, etc. are all gambling activities and they all have negative expectations.
Most blackjack players have negative expectation because they at best know basic strategy and only a very small fraction are skilled enough at advanced strategy (aka card counting) to achieve positive expectation while avoiding casino detection.
Most poker players have negative or zero expectation, only a minority are consistent winners.
Gambling consists mostly of negative- or zero-expectation activities where skill plays no part.
Those with skills that allow them to enter positive-expectation territory call themselves gamers, not gamblers.
Gamblers are losers, or temporarily lucky. But in the long run, they are losers.
The skills required to win at gaming are mostly psychological: reading the tells of other poker players, avoiding detection as a counter at the blackjack table.
The skills required to win at trading are mathematical: pattern detection, Kelly sizing.
