Gold futures options trade on COMEX, part of CME Group. Individual traders normally access these contracts through a broker that supports futures options. Having a stock options account does not automatically provide access to them.
Access through a futures broker
Start by checking whether the broker offers COMEX gold options to customers in your country. The exchange lists the contracts; the broker provides the account and trading access. CME Group maintains a broker directory that can help identify firms to investigate.
Ask specifically about options on gold futures. A platform that offers gold CFDs, spot gold or futures may not offer the option you want. Account approval, available products and funding requirements depend on the broker and your location.
Choose the exact contract
The standard COMEX gold option represents one 100-troy-ounce futures contract. A premium quoted at $40 per ounce therefore costs $4,000 for one option, before commissions and fees.
Check the underlying futures month as well as the option’s expiration date. Different expirations can have different premiums and trading activity. Use the official contract specifications and the broker’s contract details to identify what you are trading.
Options on a gold ETF are a separate product: their underlying is fund shares. Options on a mining company are stock options with exposure to that business as well as gold prices. The 100-ounce futures calculation does not apply to either.
Compare the total trading cost
The premium is only one part of the cost. Compare commissions, exchange fees and any market-data charges. Also examine the difference between the bid and ask prices for your chosen strike and expiration. A wide spread can make entering and closing a trade more expensive.
For example, an option quoted at a $38 bid and $42 ask has a $400 spread across 100 ounces. Buying at the ask and immediately selling at the bid would lose $400 before fees, even without a change in gold prices.
Understand the broker’s expiration policy
Exercising a futures option creates a futures position. Ask how the broker handles exercise, its instruction deadlines and any margin needed to hold the resulting position. Confirm whether it may close positions before expiration or delivery.
