Ftmo Position Size Calculator

FTMO (Fixed Trade Margin Option) position sizing is a crucial concept in futures trading that determines how much of your trading capital to allocate to each position. Proper position sizing helps manage risk, maintain consistency, and avoid excessive drawdowns. This guide explains how to calculate optimal FTMO position sizes and provides practical advice for traders.

What is FTMO Position Sizing?

FTMO position sizing refers to the practice of using a fixed percentage of your trading capital for each futures position. This approach helps traders maintain consistent risk exposure across different market conditions and instruments. The key principle is that each trade should risk a small, predetermined portion of your total trading capital.

Key Concepts

FTMO position sizing is based on the following principles:

Risk a fixed percentage of capital per trade
Maintain consistent risk exposure
Avoid overleveraging in any single position
Allow for multiple trades in the same direction

The most common FTMO percentages used by professional traders range from 1% to 5% of total capital. For example, if you have $100,000 in trading capital, a 2% FTMO would mean risking $2,000 per position.

How to Calculate FTMO Position Size

The basic formula for calculating FTMO position size is:

FTMO Position Size Formula

Position Size = (Total Capital × FTMO Percentage) ÷ (Entry Price × Contract Size)

Where:

Total Capital = Your total trading capital
FTMO Percentage = Your chosen FTMO percentage (e.g., 2%)
Entry Price = The price at which you plan to enter the position
Contract Size = The size of the futures contract you're trading

For example, if you have $50,000 in trading capital, want to use a 3% FTMO, and are trading a futures contract with a contract size of 100 shares, the calculation would be:

Example Calculation

Position Size = ($50,000 × 0.03) ÷ ($100 × 100) = $1,500 ÷ $10,000 = 0.15 contracts

This means you should risk 0.15 contracts (or 15 shares) per position with this setup.

Example Calculation

Let's walk through a complete example to illustrate how FTMO position sizing works in practice.

Scenario

Total trading capital: $75,000
FTMO percentage: 2%
Entry price: $2,500 per contract
Contract size: 50 shares

Step-by-Step Calculation

Calculate the maximum risk per trade: $75,000 × 0.02 = $1,500
Determine the value per contract: $2,500 × 50 = $125,000
Calculate position size: $1,500 ÷ $125,000 = 0.012 contracts
Convert to shares: 0.012 × 50 = 0.6 shares

In this scenario, you should risk approximately 0.6 shares (or 60 shares) per position. This means you could potentially hold 125 positions (75,000 ÷ 600) in the same direction before reaching your 2% FTMO limit.

Practical Considerations

In real trading, you would typically round to whole contracts or shares, and account for slippage and commission costs. The example shows the theoretical calculation without these adjustments.

Best Practices for Position Sizing

Implementing FTMO position sizing effectively requires following several best practices:

1. Choose an Appropriate FTMO Percentage

Select an FTMO percentage that aligns with your risk tolerance and trading style. Common choices range from 1% to 5%, with 2% being a good starting point for most traders.

2. Maintain Consistent Risk Exposure

Stick to your chosen FTMO percentage across all trades. This consistency helps you develop a disciplined trading approach and manage risk more effectively.

3. Consider Market Conditions

Adjust your position size based on market volatility. In highly volatile markets, you may want to reduce your position size to maintain consistent risk exposure.

4. Account for Slippage and Commissions

Factor in potential slippage and commission costs when calculating your position size to ensure you're not overleveraging your positions.

5. Monitor Position Limits

Keep track of your position limits and avoid exceeding them. This helps prevent large drawdowns and maintains your risk management discipline.

6. Review and Adjust Regularly

Periodically review your FTMO approach and adjust your percentage if needed. As your trading capital grows or your risk tolerance changes, you may want to modify your FTMO percentage.

FAQ

What is the difference between FTMO and fixed dollar position sizing?

FTMO position sizing uses a percentage of your total capital, while fixed dollar position sizing uses a fixed dollar amount regardless of your total capital. FTMO is generally preferred as it allows you to scale your position size as your capital grows.

How do I determine the right FTMO percentage for me?

The right FTMO percentage depends on your risk tolerance and trading style. Start with a conservative percentage (1-2%) and gradually increase it as you gain more experience and confidence in your trading approach.

Can I use FTMO position sizing with options?

Yes, you can adapt FTMO position sizing for options trading by calculating your position size based on the premium paid or received rather than the underlying asset's price.

How does FTMO position sizing work with leverage?

When using leverage, your effective capital increases, so you may need to adjust your FTMO percentage to maintain the same risk exposure. For example, with 2x leverage, you might use a 1% FTMO to maintain the same risk as a 2% FTMO without leverage.

What happens if the market moves against me in a large position?

If the market moves against you, your position will lose value. With proper FTMO position sizing, you should limit your losses to your predetermined percentage of capital, helping you maintain your overall risk management discipline.
