Poker is one of the most important cheat codes in trading.
Jeff Yass, worth an estimated $67 billion, trains every trader at his $500B+ hedge fund Susquehanna using poker.
As a core part of their trading education.
Why?
Because poker teaches you the exact skills that separate pro traders from everyone else: sizing bets correctly, managing risk, thinking in probabilities, and keeping your emotions in check when the variance hits.
Here are 5 poker concepts that will make you a better trader.
1. Position Sizing
This is the most important lesson poker teaches.
Even with pocket aces, one of the best starting hand in Texas Hold'em, you lose roughly 1 in 5 times. If you shoved your entire bankroll every time you had aces, you'd eventually go broke. It's not a matter of if. It's when.
Trading works the same way.
Even your highest-conviction setup will lose. Probably more often than you think. And if you're putting 30%, 40%, or 50% of your account on a single trade because "this one looks really good," you're one bad streak away from a catastrophic drawdown.
Here's the math that most traders forget: if you lose 50% of your account, you need a 100% return just to get back to even.
And it's the reason why professional poker players and professional traders obsess over the same thing, not how much they can win, but how much they can afford to lose.
Size your positions so you survive the variance. That's the whole game.
2. Table Selection Is An Edge
In poker, if you're the 10th best player in the world but you sit down at a table with the other 9 best, you're going to have a very hard time making money.
But if that same player sits at a table full of amateurs? It's almost impossible to lose over time.
Markets work like this also.
Choosing which market to trade is one of the most underrated decisions you'll ever make. Most retail traders jump straight into FX or indexes — the most competitive, most efficient markets on the planet — and wonder why they can't find edge.
Meanwhile, less-trafficked markets often offer significantly better opportunities. Emerging markets, low-liquidity crypto pairs, prediction markets. These are the "soft tables" of trading.
The institutions can't always deploy capital there efficiently. The liquidity isn't deep enough for their size and compliance hurdles could be too high.
That's your advantage.
3. Conviction
In poker, the stronger your hand and the higher the probability of winning, the more you want to bet. You don't bet the same amount with a pair of twos as you do with a full house.
This sounds obvious. But most traders completely ignore this principle.
They take the same position size on every trade regardless of how strong the setup is
The best traders, and the best poker players, scale their exposure to their conviction. When the odds are clearly in your favor and the setup is strong, that's when you lean in. When the signal is weak or the conditions are unclear, you stay small or sit it out entirely.
Card counters understood this intuitively. When the count is high and the deck favors the player, they increase their bet. When it's neutral or unfavorable, they bet the minimum.
If you don't know the odds, or they aren't in your favor, don't bet big.
4. Process Over Outcome, Every Single Time
This might be the hardest lesson in both poker and trading.
You can make the mathematically correct decision and still lose money. You can make a terrible decision and still win. In the short run, variance doesn't care about your process.
But in the long run? Process is everything.
A poker player who goes in with a 90% favorite and loses doesn't regret the decision. The decision was right. The outcome was unlucky. Those are two completely different things.
Trading is identical. You will have weeks, sometimes months, where you do everything right and still lose. You'll experience what feels like an unreasonable amount of bad luck. You might even start questioning your entire approach.
This is where most people break. They abandon a sound strategy after a losing streak because they confuse a bad outcome with a bad process.
The professionals don't do this. They evaluate decisions, not results. They ask "did I follow my system?" not "did I make money today?"
5. Develop Emotional Resilience to Variance
Poker teaches you something: how to sit with discomfort.
You will experience swings. Periods where everything that can go wrong does. Followed by stretches where you feel invincible.
Both are dangerous if you let them affect your decision-making.
The best poker players develop what some call a "zen robotic ability" to focus only on the next decision. Not the last hand. Just the current situation and the correct play.
In trading, this translates to emotional detachment from individual trade outcomes. Your job isn't to feel good about winning trades or bad about losing ones. Your job is to execute your process and let the probabilities play out over a large enough sample.
This is also why I'm a strong advocate for automating your trading strategies. When the system executes the trades, there's no opportunity for emotion to interfere. No freezing up. No revenge trading. No second-guessing a position because you're still rattled from the last loss.
Automation doesn't remove variance. Nothing does. But it removes the emotional damage that variance inflicts on your decision-making.
Closing Thoughts
What it really comes down to is this: know your edge, understand the probabilities, and build the emotional resilience to extract that edge consistently over time.
Poker teaches all three of these skills in a compressed, high-feedback environment. It's one of the best training grounds.
