I disagree that trading is like poker.
1) In order to play poker you have to ante up before any cards are dealt. In trading, you can wait (at the table so to say) until you see an opportunity.
2) Seeing the opportunity is like seeing your hand BEFORE you place a bet.
3) In a poker game only one person wins; in trading many people can win.
4) In poker people can conceal their emotions. In trading, it is impossible to conceal the buying and selling.
This post is not very accurate, and could "dispute" all points.
1) inflation is like the ante.
2) in poker you can have a guaranteed win, not so much with trading.
3) many people can win in the game, not just one hand.
4) traders can conceal with dark pools, or other more advanced trickery.
In short, in poker the games get very tough at the higher levels, and are not profitable enough (worth your time) at the lower limits. In trading you can deploy a large amount of capital much easier, and probably can't trade at all if you are at the lower levels.
