Position Sizing
Risk Management
是什么意思
Deciding how many shares or contracts to trade based on how much you are willing to lose, not on how confident you feel.
举例
With a $10,000 account, 1% risk ($100), a $100 entry, and a $95 stop ($5 risk per share), you buy 20 shares. The size comes from the risk, not from "I think it will win."
新手常犯的错
Beginners size positions by gut: "buy 1,000 shares because I am sure." Sizing by confidence, not by risk, is how one bad trade wipes out months of gains.
