Ask ten traders how much to risk per trade and you’ll get ten different answers. But the principle behind the number matters more than the number itself, and understanding that principle is what makes the rule stick when it’s tested.
The 1–2% rule exists for survival, not profit
Trading psychologist Van Tharp popularized the 1–2% rule in Trade Your Way to Financial Freedom: risking a small, fixed percentage of your account per trade means no single loss or losing streak can wipe you out.
Of your account, per trade. Van Tharp, Trade Your Way to Financial Freedom.
It’s a survival rule before it’s a performance rule, designed around the reality that even a sound strategy will produce a string of losses at some point.
Regulators already build guardrails around this
ESMA caps retail leverage at 30:1 for major FX pairs and 20:1 for non-majors, and mandates a 50% margin close-out rule per account.
These caps exist precisely because unmanaged leverage, not leverage itself, is what wipes out retail accounts — the leverage simply amplifies whatever risk discipline (or lack of it) was already there.
Consistency beats conviction
Even a “sure thing” trade should follow your normal risk rules. The moment you size up because you feel certain is usually the moment the market humbles you, and looking back, most large drawdowns trace to exactly this kind of exception.
Conclusion
Risk management isn’t the boring part of trading — it’s the part that decides whether you’re still trading a year from now. Everything else is secondary to staying in the game long enough for your edge to play out.
