Turtle Trading is a popular trading strategy developed by Richard Dennis and William Eckhardt. One of the key components of this strategy is the calculation of the position size (N), which helps traders determine how much capital to risk on each trade. This calculator helps you determine the optimal N value based on your account size and risk tolerance.
What is N in Turtle Trading?
In Turtle Trading, N represents the position size, which is the amount of capital you allocate to each trade. The calculation of N is based on your account size and your risk tolerance. The formula for calculating N is:
Formula
N = (Account Size × Risk Percentage) / Average True Range (ATR)
The Average True Range (ATR) is a technical indicator that measures market volatility. It helps traders determine the appropriate position size based on the current market conditions. By using the ATR, traders can adjust their position size to account for different levels of volatility.
Key Points
- N is calculated based on your account size and risk tolerance.
- The ATR helps adjust the position size based on market volatility.
- A smaller N value indicates a more conservative trading approach.
- A larger N value indicates a more aggressive trading approach.
How to Calculate N
To calculate N, you need to know your account size, your risk percentage, and the Average True Range (ATR) for the trading period you are considering. The steps to calculate N are as follows:
- Determine your account size.
- Choose your risk percentage (typically between 1% and 2%).
- Calculate the ATR for the trading period.
- Use the formula N = (Account Size × Risk Percentage) / ATR to calculate N.
Once you have calculated N, you can use it to determine the position size for each trade. The position size is the amount of capital you allocate to each trade, and it is calculated by multiplying N by the number of shares you want to trade.
Example
If your account size is $10,000, your risk percentage is 1%, and the ATR is $20, then N = ($10,000 × 0.01) / $20 = $100. This means you should allocate $100 to each trade.
Example Calculation
Let's walk through an example to illustrate how to calculate N. Suppose you have an account size of $20,000, a risk percentage of 1.5%, and an ATR of $30.
- Account Size = $20,000
- Risk Percentage = 1.5% = 0.015
- ATR = $30
- N = ($20,000 × 0.015) / $30 = $300
In this example, N is $300. This means you should allocate $300 to each trade. By using this calculation, you can ensure that you are risking a consistent amount of capital on each trade, which helps you manage your risk effectively.

| Account Size | $20,000 |
| Risk Percentage | 1.5% |
| ATR | $30 |
| N | $300 |
Frequently Asked Questions
What is the purpose of calculating N in Turtle Trading?
The purpose of calculating N is to determine the optimal position size for each trade. By using N, traders can ensure that they are risking a consistent amount of capital on each trade, which helps them manage their risk effectively.
How does the ATR affect the calculation of N?
The ATR (Average True Range) measures market volatility. A higher ATR indicates higher volatility, which means you should allocate a smaller position size to each trade. Conversely, a lower ATR indicates lower volatility, which means you can allocate a larger position size to each trade.
What is a good risk percentage to use when calculating N?
A good risk percentage to use when calculating N is typically between 1% and 2%. This means you should risk 1% to 2% of your account size on each trade. By using a consistent risk percentage, you can ensure that you are managing your risk effectively.
How often should I recalculate N?
You should recalculate N whenever there is a significant change in your account size, risk tolerance, or market conditions. Typically, you should recalculate N at the beginning of each trading period or whenever you make a significant change to your trading strategy.
Can I use the same N value for all trades?
Yes, you can use the same N value for all trades. By using a consistent N value, you can ensure that you are risking a consistent amount of capital on each trade, which helps you manage your risk effectively. However, you should adjust N whenever there is a significant change in your account size, risk tolerance, or market conditions.
