Key Takeaways
- Risk per trade is a decision you make in advance, using your own tested framework — not a single number every trader should copy.
- Position size is the output of a formula (account, risk %, stop distance, instrument value), not a starting point you pick by feel.
- A stop-loss placed where your trade thesis is actually invalidated protects you far better than one placed at a 'comfortable' distance.
- Risk management is what keeps you in the game long enough for a real edge to show up in the results.
Risk management is the practice of deciding, before you ever open a position, how much of your account you're willing to lose if a given trade goes wrong — then sizing and structuring the trade so that's genuinely the outcome if your stop is hit. It's the foundation most professional trading is built on, not because professionals avoid losses, but because they cap them deliberately instead of discovering the size of a loss after the fact.
Most new traders spend their early effort hunting for a better strategy. Professional traders spend a comparable amount of effort making sure no single trade, or short losing streak, can meaningfully damage the account — because a strategy with a real edge still needs enough surviving capital to let that edge play out over time.
What is Risk?
In this context, risk means the amount you stand to lose on a single trade if it fails — measured in money, and usually expressed as a percentage of your account so it scales sensibly as your balance changes. It is not the same as position size, leverage, or how volatile an instrument is; those are inputs that feed into risk, not risk itself.
Risk Per Trade
The amount, in %, you're prepared to lose if this specific trade fails
Exit Placement
The price level at which the trade idea is actually wrong
Position Size
The output that connects your risk amount to your exit distance
Risk-to-Reward
What you stand to gain against what you're risking to get there
Position Sizing
Position size is the number of units or lots you trade so that, if your stop-loss is hit, you lose the specific amount you decided to risk — no more, no less. It's calculated after your risk amount and stop distance are already set, using the instrument's own contract specification for pip or point value.
| Step | Illustrative Value |
|---|---|
| Account balance | $2,000 |
| Illustrative risk (1% — example only) | $20 |
| Stop distance | 30 pips |
| Assumed value at 1 standard lot | $10 per pip |
| Position size | 20 ÷ (30 × 10) = 0.0667 standard lots |
Setting Stop-Losses
A stop-loss works best when it's placed at the point where your original trade thesis is actually invalidated — not at a distance chosen because it feels emotionally comfortable, and not moved further away mid-trade to avoid taking a loss you've already decided against. Different strategies use different logic here: structural levels, volatility-based distances, time-based exits, or portfolio-level rules — the specific method matters less than having one, defined in advance.
A Stop That Holds Up
- Placed where the trade thesis is genuinely wrong, not where it's merely uncomfortable
- Set before the trade, using a rule the strategy defines
- Left alone once the trade is open, even when it's tested
A Stop That Doesn't
- Set at a round-number distance with no stated reason
- Widened after entry to avoid realising a loss
- Ignores the instrument's normal volatility entirely
Risk-Reward Ratios
A risk-reward ratio compares what you're risking on a trade against what you stand to gain if it works — a 2:1 ratio means aiming to make twice what you're risking. This matters because it sets the win rate a strategy needs just to break even, before costs: the higher the ratio, the lower that breakeven win rate becomes.
| Risk:Reward | Theoretical Breakeven Win Rate (Before Costs) |
|---|---|
| 1:1 | 50% |
| 2:1 | ~33.3% |
| 3:1 | 25% |
The Psychology of Risk
Risk rules are easy to agree with on a calm day and much harder to follow mid-trade, when a position is moving against you and the temptation to widen a stop or add to a loser feels justified in the moment. This is exactly why the rules need to be decided in advance, in writing, rather than negotiated with yourself while a trade is open.

No — 1% is a commonly used illustrative example, but the right figure depends on your strategy's variability, your stop distance, and your own tested framework, not a universal rule.
No — leverage determines how much margin a position requires. Your actual risk is set by your stop distance and position size, independent of the leverage used to open it.
Sizing a position by feel instead of by formula — picking a lot size first and discovering the real dollar risk afterward, rather than deciding the risk amount before the position size is calculated.
