Futures Position Size & Risk Management Guide

Understanding Position Sizing

Position sizing is one of the most critical aspects of successful futures trading. It determines how much capital to risk on each trade and helps manage overall portfolio risk.

Key Components of Position Sizing

• Account Size: Your total trading capital available for futures trading
• Risk Percentage: The percentage of your account you're willing to risk per trade (typically 1-2%)
• Stop Loss Distance: The distance from entry to stop loss in points or ticks
• Contract Size: The size of one futures contract (varies by instrument)
• Tick Value: The dollar value of one tick movement
• Entry Price: Your planned entry price for the trade

Risk Management Principles

Margin and Leverage

• Initial Margin: The minimum amount required to open a position
• Maintenance Margin: The minimum balance required to keep a position open
• Leverage: The ratio of position size to required margin (e.g., 10:1 leverage)
• Margin Call: When account balance falls below maintenance margin

Stop Loss Strategies

• Fixed Dollar Risk: Risk a fixed dollar amount per trade regardless of position size
• Percentage Risk: Risk a fixed percentage of account per trade
• Volatility-Based: Set stops based on market volatility (ATR)
• Support/Resistance: Place stops beyond key support/resistance levels

Frequently Asked Questions

Q: How do I calculate position size for futures?

A: Position size = (Account Size 脳 Risk Percentage) 梅 (Stop Loss Distance 脳 Tick Value). This ensures you risk only your predetermined percentage per trade.

Q: What is the 1% risk rule?

A: The 1% rule states that you should never risk more than 1% of your account on any single trade. This allows you to survive losing streaks and maintain long-term profitability.

Q: How does leverage affect position sizing?

A: Higher leverage allows larger positions with less capital, but also increases risk. Always calculate position size based on your risk tolerance, not maximum leverage available.

Q: What is the difference between initial and maintenance margin?

A: Initial margin is required to open a position, while maintenance margin is the minimum balance needed to keep it open. If your account falls below maintenance margin, you'll receive a margin call.

Q: How do I set proper stop losses?

A: Set stops based on market structure (support/resistance), volatility (ATR), or a fixed dollar risk. Avoid placing stops too close to entry to prevent premature exits.

Q: What is a good risk/reward ratio?

A: Aim for at least 1:2 risk/reward ratio (risk $1 to make $2). Higher ratios like 1:3 or 1:4 are even better for long-term profitability.

Q: How do I manage multiple positions?

A: Ensure total risk across all positions doesn't exceed your daily risk limit. Consider correlation between positions to avoid over-concentration in similar markets.

Q: What should I do if I get a margin call?

A: Either add more funds to meet margin requirements or close some positions to reduce margin usage. Never ignore margin calls as positions may be forcibly closed.
