It sounds like a simple rule, yet breaking it is the number one reason traders blow up their accounts. In this episode, we move past the intellectual knowledge of risk and build the practical and emotional defenses necessary for long-term survival.
We unpack the "Casino Mindset"—learning to think like the house by spreading risk across thousands of small bets rather than gambling on a "sure thing". You will learn the "Golden Rule of Risk," why risking more than 2% per trade mathematically leads to the Probability of Ruin, and how to use a simple position sizing formula to remove emotion from your trading decisions. We also discuss why viewing controlled losses as "rent" is the key to staying in the game long enough for compounding to work its magic.
Tools & Formulas Discussed: Position Sizing Formula, Probability of Ruin (POR), Monte Carlo simulations, and automated conditional orders.

Key Takeaways
- The Golden Rule of Risk: Never risk more than 1% to 2% of your total account capital on any single trade. This acts as a mathematical firewall against the Probability of Ruin, ensuring that even a long losing streak cannot wipe out your account.
- Risk vs. Position Size: It is vital to distinguish between the total amount invested and the amount at risk. While you might invest $5,000, your risk is the dollar difference between your entry price and your stop loss.
- The Position Sizing Formula: Use math to remove greed and fear. Calculate your size by taking your Max Risk in Dollars (Account Size x Risk %) and dividing it by your Trade Risk per Share (Entry Price - Stop Loss Price).
- Longevity Beats Speed: Trading is a marathon, not a sprint. Shallow drawdowns from small risks are easy to recover from (a 10% loss needs only an 11% gain to break even), whereas deep drawdowns from over-risking are often permanent account killers.
- Risk as "Rent": Shift your mindset to view small, controlled losses not as failures, but as the cost of doing business. Paying this "rent" provides the opportunity to operate in the markets and stay in the game.
"You can't control whether a trade wins or loses, but you—and only you—control how much you lose when you're wrong."
