Gold Futures Contract Specifications
Gold futures trade under the ticker GC on the COMEX exchange, part of CME Group. One GC futures contract represents 100 troy ounces of gold. Each tick equals $0.10 per ounce, which translates to $10 per contract (100 ounces × $0.10). The minimum price fluctuation stands at $0.10, making it easy to calculate profit and loss per tick.
The contract size remains fixed at 100 troy ounces. Gold prices fluctuate in dollar amounts per ounce. For example, if gold moves from $2,000 to $2,001, the contract value changes by $100 (100 ounces × $1). The contract’s trading hours extend nearly 24 hours, opening Sunday at 6:00 p.m. ET and closing Friday at 5:00 p.m. ET, with a 60-minute break daily from 5:00 p.m. to 6:00 p.m. ET.
The tick value is crucial for day traders. Small price movements translate directly into dollar gains or losses. For instance, a 15-tick move equals $150 profit or loss per contract. This granularity lets traders size their positions to fit risk tolerance.
Margin Requirements and Leverage
COMEX sets initial and maintenance margin levels for GC contracts. Initial margin hovers around $6,000 per contract, while maintenance margin sits near $5,400. These amounts adjust with market volatility and exchange rules. Margin requirements represent only a fraction of the contract’s notional value. For example, at a $2,000 gold price, the notional contract value equals $200,000 (100 ounces × $2,000), so initial margin represents roughly 3% of total exposure.
Leverage magnifies gains and losses. Holding one GC contract exposes a trader to $200,000 worth of gold with $6,000 margin. This leverage ratio of about 33:1 demands strict risk management. A 1% move in gold price ($20 per ounce) translates to $2,000 profit or loss (100 ounces × $20), which is 33% of the initial margin.
Traders must maintain maintenance margin to avoid margin calls. Falling below $5,400 triggers a requirement to deposit funds or liquidate positions. Volatile markets increase margin requirements, especially during geopolitical events or economic releases. Exchanges raise margins to protect clearinghouses from default risk.
Trade Example: Long GC Futures Day Trade
Assume gold trades at $2,000 per ounce. A trader expects a short-term bounce based on technical support near $1,995. The trader enters long one GC contract at $1,995. The stop loss sits 10 ticks below entry, at $1,994.00, equating to a $100 risk (10 ticks × $10). The profit target lies 30 ticks above entry, at $1,998.00, for a $300 reward.
Entry price: $1,995.00
Stop loss: $1,994.00 (10 ticks / $100 risk)
Target price: $1,998.00 (30 ticks / $300 reward)
The risk-to-reward ratio equals 1:3. If the trade hits the target, the trader nets $300. If the stop triggers, the trader loses $100.
This trade works well when gold bounces off strong support with low volatility. The small stop limits losses while the target captures a brief momentum surge. It fails during sharp, fast-moving declines where price breaks support quickly and accelerates lower, exceeding the stop loss. It also struggles if gold grinds sideways, failing to hit the target before the stop triggers or the trader exits early.
When Contract Specifications and Margin Hurt Traders
High leverage tempts traders to increase position size beyond prudent limits. Trading multiple contracts without adjusting stops can amplify losses. For example, risking $100 per contract across five contracts exposes the trader to $500 risk per trade. Small adverse moves can wipe out a large portion of margin.
Margin calls often occur during unexpected gold price gaps. Since GC trades nearly 24 hours, news releases after regular sessions can cause overnight moves exceeding stop losses. Traders holding positions without adequate margin face forced liquidations at unfavorable prices.
Tick size and contract size can confuse new traders. The $10 tick value per contract means a 5-tick loss equals $50. Misunderstanding this can cause mispriced stops or position sizes incompatible with account size.
Day traders should monitor margin levels continuously. Rising volatility increases margin, reducing available buying power. Failure to reduce position size or add funds can result in forced position closure.
Key Takeaways
- One GC contract equals 100 troy ounces of gold; each tick equals $10.
- Initial margin stands near $6,000, enabling ~33:1 leverage on a $200,000 notional position.
- Use tight stops and realistic targets to manage risk: a 10-tick stop versus 30-tick target offers a 1:3 reward-to-risk ratio.
- High leverage increases risk of large losses and margin calls, especially during volatile or gap moves.
- Understand contract size and tick value fully to size positions and stops appropriately.
