Drawdown Tolerance
Your genuine psychological capacity to endure account drawdowns without deviating from your strategy — different from what you think you can handle.
Drawdown tolerance is not what you say you can handle when the account is flat — it is what you actually do when you are 15% below your high-water mark. Most traders discover, too late, that their true tolerance is far lower than their theoretical one.
The gap between stated and actual drawdown tolerance causes strategy abandonment at the worst time. A system is in a normal 12% drawdown. The trader, who thought they could handle 15%, panics at 12% and stops trading it — right before it recovers. They locked in the loss and missed the recovery.
Test your true drawdown tolerance through position sizing. Size positions so that a full strategy drawdown, in dollar terms, is genuinely within your emotional comfort zone — not just within your account's survival threshold.
