Risk management is not about predicting price movements, but about deciding in advance how much you will lose if you’re wrong. Before every trade, write down your entry rationale, your invalidation level, and the maximum loss you can tolerate—then work backward to determine your position size. Don’t go all-in just because you’re optimistic, and don’t add to your position to average down after you’re losing. People who can survive in the long run usually aren’t right every time; they simply ensure that when they’re wrong, their losses are small enough.
