Quote from magix3d:
What aspects of poker will help an aspiring trader? I'm a fairly horrible poker player and I was thinking that getting better at poker would help my patience. Thoughts?
Three key factors:
1. Learning to recognise and handle 'tilt' (a state of emotional decision-making caused by anger/distress at large losses or bad luck).
This is absolutely critical for a trader. If you ever tilt, and do not always stop playing/trading soon after the tilt begins, you WILL go bust. Simple as that. Poker is excellent training for this, because tilting in poker will also make you go bust pretty quickly if you don't nip it in the bud.
2. Learning to become indifferent to money.
As a poker player, you must be able to go all-in without caring whether you win or lose on the hand. If you can't do this, you will get slaughtered by players who can disassociate their emotions, as they will simply bluff you off your hands by betting above your comfort level whenever they sense weakness.
As a trader, you must be able to make trading decisions based purely on the market setup and market action - there should be no input at all based on how much you are up or down on the position, or your overall portfolio. Your trade decision-making process should be identical whether you are betting $0.1% or 10% of your account equity, whether you are in a 30% drawdown or if you are up 100% on the month. If you cannot do this, you will always make sub-optimal trades whenever the stakes are higher than your comfort zone.
3. Learning about losing streaks and variance, through experience.
No matter how much statistical theory you know, how many Monte Carlo runs you do, you won't fully appreciate the reality of losing streaks until you experience them first-hand. Poker helps train you to handle these and the emotions that initially come with them. You need to be able to trade just as well at the end of a 25 trade losing streak as you do after a nice winning run - poker helps with this as losing streaks are even more common than they are with trading. The same is true with variance, no-limit poker is even more variable than (most) trading, so it's good training for this aspect.
Poker can also help a bit with patience and discipline, as you need to be able to pass on a lot of hands, only playing when you get strong hole cards.
The one thing poker is completely useless for is any kind of market knowledge. In fact, it's harmful for this, as it takes time you could use to be researching market history and behaviour. Poker also is a closed system and has far less black/grey swans than markets do.
