Lesson 2 of 8 · 2 min
Risk appetite
How much risk you can actually handle — financially and emotionally — and how to set it before the market sets it for you.
Risk appetite is how much loss you're willing and able to take in pursuit of a return. It has two parts, and you need both to be honest.
1. Risk capacity — what you can afford
The money in a trading account should be money you could lose without changing your life. Not rent, not savings you'll need, not borrowed money.
Rule zero
If losing your whole account would hurt your life, the account is too big — or you shouldn't be trading it yet. Start in simulation or with micros.
2. Risk tolerance — what you can stomach
This is emotional. Two traders with the same account can react very differently to a $300 loss. Signs your size is above your tolerance:
- You move your stop because you "can't take" the loss.
- You watch P&L instead of the chart.
- One loss ruins your day, or your sleep.
- You size up after a loss to "make it back".
Setting your numbers
Write these down before your next session:
| Limit | Example | Why |
|---|---|---|
| Risk per trade | 0.5–1% of account | Survives long losing streaks |
| Daily loss limit | 2–3 trades' worth of risk | Stops one bad day becoming a bad month |
| Weekly loss limit | ~5% of account | Forces a step back and a review |
| Max contracts | e.g. 2 MES | Stops "just this once" sizing |
These are common starting points, not rules for everyone. Lower is fine. Higher needs evidence.
The test
If you'd be calm taking your max loss five times in a row, your risk is about right. If that thought makes you uncomfortable, cut it.
Risk appetite changes
It drops after a drawdown, rises after a winning streak — usually the opposite of what's helpful. Fixed, written limits protect you from your own mood.
Quick recap
- Capacity: only trade money you can lose.
- Tolerance: size so losses don't change your behaviour.
- Write per-trade, daily and weekly limits — before you need them.
