Gold Futures Contract Specifications
Gold futures trade under the ticker GC on the COMEX exchange. Each GC contract represents 100 troy ounces of gold. The contract price reflects the cost per troy ounce in U.S. dollars. For example, if gold trades at $2,000 per ounce, one GC contract equals $200,000 in notional value (100 ounces × $2,000/ounce).
The minimum price fluctuation, or tick size, for GC is $0.10 per ounce. This equates to $10 per contract since 100 ounces × $0.10 = $10. Traders gain or lose $10 for every 0.10 movement in gold’s price per ounce. The daily price limit for GC varies but typically stands at $100 per ounce, equivalent to $10,000 per contract.
GC contracts expire monthly, with the last trading day set for the third last business day of the delivery month. Most traders close positions before expiry to avoid physical delivery. Contract months include February, April, June, August, October, and December.
Margin Requirements and Capital Efficiency
The initial margin for one GC contract fluctuates based on volatility and market conditions. Currently, the CME requires about $7,500 to $9,000 initial margin per contract. Maintenance margin sits around 75% of the initial margin, usually $5,600 to $6,750. Futures margin represents good faith collateral, not the full contract value.
Compare margin with the notional contract value of roughly $200,000. The margin requirement of $8,000 represents a 4% capital outlay. This leverage allows traders to control large gold positions with limited capital but increases risk exposure.
Margin calls occur when account equity falls below maintenance margin. Traders must add funds or close positions immediately to avoid liquidation. Using tight stops limits margin drawdown risk.
Trading the GC Contract: Worked Example
Assume gold trades at $2,000 per ounce. You spot a short-term pullback setup in GC futures. Price rallies to $2,010, then forms a bearish engulfing candle. You short one GC contract at $2,010.
Set a stop loss at $2,020, 10 points above entry. Each point movement equals $100 (since 1 point = $1 per ounce × 100 ounces). The stop loss risk equals 10 points × $100 = $1,000.
Set a profit target at $1,990, 20 points below entry. The reward equals 20 points × $100 = $2,000.
Calculate risk-to-reward ratio (R:R) as $2,000 / $1,000 = 2:1. This favorable ratio aligns with disciplined trading rules.
If the trade hits the stop, you lose $1,000 plus commissions. If it reaches target, you gain $2,000 minus commissions. The trade duration may last 30 minutes to 2 hours depending on intraday volatility.
This setup works best in trending or range-bound markets where short-term reversals occur near resistance levels. It fails during sudden news events or breakouts where price quickly breaches stop levels.
When GC Contract Trading Works and When It Fails
Trading GC futures works well with clear technical levels. Support and resistance zones derived from volume profiles, moving averages, or Fibonacci retracements provide entry and exit points. High liquidity during U.S. trading hours (8:20 AM to 1:30 PM EST) ensures tight spreads, reducing slippage.
Strong intraday trends allow momentum trades with trailing stops. Range markets favor mean reversion trades near extremes. Volatility tends to rise around economic reports related to inflation or interest rates, impacting gold prices.
Trading fails during low liquidity periods outside core trading hours. Spreads widen, and slippage increases. Unexpected geopolitical events or Federal Reserve announcements can trigger erratic price spikes. Stops may be hit prematurely or missed entirely during fast moves.
Leverage amplifies both profits and losses. Excessive position size relative to account equity leads to margin calls and forced liquidation. Ignoring margin requirements or holding positions overnight without hedging increases risk.
Key Takeaways
- Each GC futures contract equals 100 troy ounces of gold; $0.10 tick size equals $10 per contract move.
- Initial margin stands near $8,000 per contract, representing about 4% of notional value.
- A typical trade uses defined entry, stop, and target to maintain favorable risk-to-reward ratios (e.g., 2:1).
- GC futures trade best during high liquidity U.S. market hours and with clear technical setups.
- Avoid trading during low liquidity or major news events; manage leverage and margin carefully to limit losses.
