Risk per trade is the amount of account equity you are prepared to lose if your stop-loss is triggered. For most traders, 0.5% to 1% of account equity is a practical range, with 1% as a sensible default. Use 0.25% to 0.5% if you are new, trading a volatile market or using leverage. Treat 2% as an aggressive upper limit, not a target.
Risk per trade is not 1% of the trade's total value. It is also not the same as using 1% of your account as margin.
CME Group describes the widely used 2% rule as arbitrary and shows how a 1% limit can reduce the damage caused by consecutive losses.
What Is a Practical Risk Per Trade?
A practical risk level depends on your experience, strategy, market and exposure to leverage.
| Trading situation | Practical risk per trade |
|---|---|
| New trader or untested strategy | 0.25% to 0.5% |
| Most traders with a tested strategy | 0.5% to 1% |
| Experienced trader with validated results | 1% to 2% |
| Highly volatile or leveraged market | 0.25% to 0.5% |
| Several correlated positions | Reduce risk on each position |
These are guidelines, not universal rules. Set the percentage low enough that several consecutive losses do not damage your ability to keep trading rationally.
How Do You Calculate Dollar Risk?
Dollar risk equals account equity multiplied by the risk percentage:
Dollar risk = account equity × risk percentage
Examples:
- A $5,000 account at 1% risk allows a planned loss of $50.
- A $10,000 account at 1% risk allows a planned loss of $100.
- A $25,000 account at 0.5% risk allows a planned loss of $125.
- A $50,000 account at 2% risk allows a planned loss of $1,000.
Use current account equity rather than your original deposit. If the account falls, the dollar amount allocated to the next trade should fall as well when you use fixed-percentage position sizing.
How Do You Calculate Position Size?
Position size equals your dollar risk divided by the risk per unit:
Position size = dollar risk ÷ risk per unit
For a long stock trade:
Risk per share = entry price − stop-loss price
Example
You have a $10,000 account and risk 1% per trade:
- Maximum planned loss: $100
- Entry price: $50
- Stop-loss price: $48
- Risk per share: $2
- Position size: $100 ÷ $2 = 50 shares
The position is worth $2,500, but the planned risk is approximately $100 before commissions, fees and slippage.
A wider stop requires a smaller position. A tighter stop allows a larger position. The risk percentage stays the same while the position size changes.
Include estimated transaction costs and slippage, then round the position size down.
Why Is 1% a Strong Default?
A 1% risk limit gives a strategy room to experience a losing streak without creating an immediate recovery problem.
Assuming every loss equals the selected percentage of current equity:
| Risk per trade | Account drawdown after 10 consecutive losses |
|---|---|
| 1% | 9.56% |
| 2% | 18.29% |
| 5% | 40.13% |
| 10% | 65.13% |
A 10% drawdown requires an 11.11% gain to recover. A 40% drawdown requires a 66.67% gain. Losses therefore become harder to recover from as the drawdown grows.
Fixed-percentage sizing also reduces the dollar amount risked on later trades during a losing streak. That slows the decline in account equity.
When Should You Risk Less Than 1%?
Use a lower percentage when:
- Your strategy has not been tested across different market conditions.
- You have limited trading experience.
- You trade options, futures, forex, CFDs or volatile cryptocurrency markets.
- The instrument has low liquidity or wide spreads.
- Your stop-loss is far from the entry price.
- Other open positions are exposed to the same sector, currency or market.
- A single loss would affect your decision-making.
Leverage lets you control a large position with less capital, but it also magnifies losses. The Commodity Futures Trading Commission warns that futures and retail forex trading can be highly volatile, and losses can exceed the amount initially deposited in some circumstances.
How Is Risk Per Trade Different From Margin?
Risk per trade is the amount you expect to lose if the trade reaches its exit point. Margin is the capital required to open or maintain the position.
For example:
- Account equity: $10,000
- Margin required: $1,000
- Planned stop-loss risk: $100
The trade uses 10% of the account as margin but risks 1% based on the planned stop. Margin does not determine a safe position size. Stop distance, contract value, leverage and potential market movement determine the actual risk.
Does a Stop-Loss Guarantee the Maximum Loss?
No. A stop order becomes a market order when its stop price is reached. The final execution price can be worse than the stop price, especially during gaps, fast markets or periods of low liquidity.
A stop-limit order gives you more control over the execution price, but it may not execute if the market moves past the limit price.
If you plan to risk 1%, allow for possible slippage rather than assuming the order will fill exactly at the stop price.
Should You Ever Risk 2% Per Trade?
You can, but 2% is better suited to a well-tested strategy, liquid markets and a trader who can tolerate a large losing streak.
CME Group uses 2% as an example of a popular risk rule but says the threshold is arbitrary. A lower percentage may be more suitable for a high-variance strategy, leveraged products or several correlated positions.
Risking 5% or 10% per trade is usually too aggressive for a normal trading account. A short sequence of losses can create a drawdown that requires a much larger gain to recover.
What Simple Rule Can You Use?
If you need one starting point:
- Set maximum risk at 1% of current account equity.
- Reduce it to 0.25% to 0.5% for new strategies, leveraged products or volatile markets.
- Calculate position size from the stop-loss distance.
- Include commissions, spreads and likely slippage.
- Reduce risk when several trades are highly correlated.
- Do not increase position size simply because you want to make more money on the trade.
Position size should adapt to the stop-loss distance. Total account risk should remain controlled until you have enough verified performance data to justify a different percentage.
