Risk Tolerance Self-Assessment: Match Size to Your Sleep

Two tolerances diverge in every trader: financial (what you can afford to lose) and emotional (what you can lose without breaking the system). Always size to the lower of the two. Most blow-ups come from sizing to the financial number while ignoring the emotional one.

The questionnaire (answer honestly, not aspirationaly)

1. If your account dropped 20% in a month, would you (a) increase size to recover, (b) keep trading the same, (c) reduce size or pause?
2. Largest single-trade loss you have slept comfortably through, as a percentage of your account?
3. Do you check open positions more than once an hour? Yes usually means sizing is too big.
4. After a loss, how long until you feel calm enough to follow your plan? Under 5 min / about an hour / next day / still bothered days later.
5. What drawdown would make you quit trading entirely? This is your hard ceiling — never risk a path there.
6. Is the trading capital money you can afford to lose without lifestyle impact? If no, stop and reduce to an affordable amount.

Scoring rule of thumb

• If you check positions hourly, lose sleep, or answered (a) to Q1 → cap risk at 0.5% per trade.
• If you sleep through 5% drawdowns and answered (c) to Q1 → 1–1.5% is workable.
• Above 2% requires all three: full-time focus, a validated backtest of 100+ trades, and an emotional ceiling above 30% drawdown.

The number that matters

It is not the risk number you would tell a friend. It is the drawdown that would make you abandon your rules — freeze, revenge-trade, or quit. Size below that line by a margin. Most retail traders discover their true tolerance is 0.5–1%, not the 3–5% they started with.

Re-test quarterly

Tolerance shifts with life: a job change, a new expense, a recent drawdown all lower it. Re-run the questionnaire every quarter and after any 15%+ drawdown. If the new number is lower than your current sizing, reduce immediately — do not wait for the market to force the lesson.
