Trading & Psychology
Market psychology, risk management, and the mental game.
The Fear of Losing Money
chrisperruna.comScared money is dead money. The difference between successful and unsuccessful investors isn't intelligence—it's psychology. Accept that losses are inevitable, focus on positive expectancy over time, and never let fear paralyze decision-making.
The Holy Grail of Trading: It's Not Your System
chrisperruna.comEveryone chases the perfect system, but that's not what separates winners from losers. The Market Wizards all used wildly different strategies—what they shared was psychological mastery and disciplined money management. It's you that makes the system work, not the other way around.
Position Sizing and Expectancy
chrisperruna.comThe math behind survival. Position size = risk % ÷ stop loss %. Expectancy = (win rate × avg win) - (loss rate × avg loss). A 40% win rate can still be highly profitable with proper sizing. Commissions and slippage can kill an edge—treat it like a business, not gambling.
