Risk limits are the rules that cap how much risk a trader, strategy or firm can take. They convert good intentions into enforceable boundaries: no position larger than this, no more than this much exposure to one sector, stop trading after losing this much in a day, cut size after a drawdown of this depth. Limits protect against the times when judgement is weakest, during losing streaks, euphoria or panic. Every trading firm runs a limit framework, and individual traders benefit from the same structure.

## Types of limits

| Limit | Caps | Example |
|---|---|---|
| Position size | Size of any single position | No more than 10% of capital in one stock |
| Risk per trade | Loss if a stop is hit | 1% of account per trade. See [Fixed Percentage vs Fixed Dollar Risk](https://learn.tradelabsai.com/risk/fixed-percentage-risk/) |
| Gross exposure | Total long plus short value | 150% of capital |
| Net exposure | Long minus short value | Between minus 20% and plus 60% |
| Concentration | Exposure to a sector, country or factor | 25% of risk in any sector. See [Concentration Risk](https://learn.tradelabsai.com/risk/concentration-risk/) |
| Open risk (portfolio heat) | Total risk of open positions | 5% of account. See [Portfolio Heat](https://learn.tradelabsai.com/risk/portfolio-heat/) |
| Daily loss | Loss in one day | Stop trading after minus 2%. See [Maximum Trade Risk and Daily Loss Limits](https://learn.tradelabsai.com/risk/daily-loss-limit/) |
| Drawdown | Fall from the equity peak | Halve size after minus 10%, stop after minus 20% |
| VaR or ES | Statistical risk | 1 day 99% VaR below 3% of capital. See [Value at Risk (VaR)](https://learn.tradelabsai.com/portfolio/value-at-risk/) |
| Liquidity | Position versus traded volume | No more than 5 days to exit at 20% of volume. See [Liquidity Risk](https://learn.tradelabsai.com/portfolio/liquidity-risk/) |

## Hard and soft limits

| | Soft limit | Hard limit |
|---|---|---|
| Effect when reached | Warning and review | Trading blocked or positions cut |
| Purpose | Early alert | Absolute boundary |
| Example | Alert at 1.5% daily loss | Stop at 2% daily loss |

Using both gives time to react before the hard stop forces action.

## Drawdown based scaling

Many professional traders cut risk as losses grow, then restore it gradually after recovery.

**Example: A drawdown ladder**
A trader with a $100,000 account normally risks 1% per trade. Their rules: at a 5% drawdown from the equity peak, cut risk per trade to 0.75%; at 10%, cut to 0.5%; at 15%, stop trading for a week and review; at 20%, stop and reassess the strategy entirely. After a run of losses takes the account to $90,000, a 10% drawdown, each trade now risks $450 instead of $1,000. This slows further losses: ten more losing trades at 0.5% cost about 4.9% of the remaining capital instead of about 9.6% at 1%. Risk returns to normal only after the account regains a set share of the loss. See [Drawdown Recovery Calculator](https://learn.tradelabsai.com/tools/drawdown-recovery-calculator/).

## Setting limit levels

1. **Start from what you can afford to lose** in a day, a month and overall.
2. **Use the strategy's history:** set drawdown limits beyond normal drawdowns but before ruin. See [Maximum Drawdown](https://learn.tradelabsai.com/portfolio/maximum-drawdown/).
3. **Stress test:** check limits against extreme scenarios. See [Stress Testing and Scenario Analysis](https://learn.tradelabsai.com/portfolio/stress-testing/).
4. **Account for correlation:** several positions in one theme count as one. See [Correlation Management](https://learn.tradelabsai.com/portfolio/correlation-management/).
5. **Write them down** and review periodically, not in the middle of a losing day.

## Enforcing limits

Limits only work if they are enforced automatically or by someone independent. In firms, risk managers separate from traders monitor and enforce them. For individuals, use broker tools such as maximum order sizes, daily loss lockouts and bracket orders, or code limits into bots. See [Risk Controls and Kill Switches](https://learn.tradelabsai.com/algo-trading/risk-controls-and-kill-switches/) and [Bracket Orders](https://learn.tradelabsai.com/orders/bracket-orders/).

## Common mistakes

1. **Raising limits after breaching them,** which defeats the purpose.
2. **Limits too loose** to ever bind.
3. **Ignoring correlated positions.**
4. **No consequences** for breaches.
5. **Changing limits emotionally** during drawdowns or winning streaks. See [Tilt](https://learn.tradelabsai.com/psychology/tilt/) and [Overconfidence](https://learn.tradelabsai.com/psychology/overconfidence/).

## Frequently asked questions

### What are risk limits in trading?

Predefined caps on position sizes, exposures, losses and drawdowns that keep risk within a planned range.

### What is a good daily loss limit?

Many traders use around 2% to 3% of account value, set so that a few bad days cannot cause serious damage.

### Should I reduce position size during a drawdown?

Many professionals do, using a ladder that cuts risk at set drawdown levels and restores it gradually after recovery.
