To trade gold futures, start by choosing the contract size, not by guessing where gold will go. CME currently lists several COMEX gold futures sizes, including GC (100 troy ounces), QO E-mini Gold (50 ounces), MGC Micro Gold (10 ounces), and 1OZ (1 ounce). The same $1-per-ounce gold move therefore changes one contract's value by about $100, $50, $10, or $1 respectively.

After choosing the contract, verify its current trading hours, expiration rules, exchange and broker margin, fees, and settlement details. Those inputs can change; a fixed dollar "minimum account size" copied from an old article is not a reliable trading rule.

Key takeaways

GC, QO, MGC, and 1OZ provide very different dollar exposure to the same gold-price move.
1OZ is now a 24/7 COMEX contract, subject to CME maintenance windows; the larger gold futures contracts follow the usual Globex weekday schedule.
Futures margin is collateral, not the maximum amount you can lose.
Exchange margin and a broker's house requirement can differ, so check both before placing a trade.
A useful risk calculation starts with price distance × contract ounces × number of contracts, then adds fees and execution risk.

This guide is educational only. Futures are leveraged products and can produce losses larger than the cash initially posted as margin. Verify current CME specifications and your broker's rules before trading.

Gold futures contract sizes: GC vs QO vs MGC vs 1OZ

The most important choice for a beginner is how much gold one contract represents.

Contract	Symbol	Contract size	Minimum price move	Approx. P&L change for a $1/oz gold move	Typical trading schedule
Gold futures	GC	100 troy oz	$0.10/oz = $10 per contract	$100	Nearly 23 hours/day, Sunday-Friday
E-mini Gold futures	QO	50 troy oz	$0.25/oz = $12.50 per contract	$50	Globex weekday schedule
Micro Gold futures	MGC	10 troy oz	$0.10/oz = $1 per contract	$10	Nearly 23 hours/day, Sunday-Friday
1-Ounce Gold futures	1OZ	1 troy oz	$0.25/oz = $0.25 per contract	$1	24/7, subject to scheduled maintenance

The dollar effect comes directly from contract size. If gold moves from $4,000 to $4,008 per ounce, an $8 move corresponds to about:

GC: $800 per contract
QO: $400 per contract
MGC: $80 per contract
1OZ: $8 per contract

That does not mean the smaller contract is automatically safer. Smaller unit size lowers the dollar value of each price move, but execution, leverage, gaps, liquidity, fees, and behavioral risk still matter.

CME describes GC as its benchmark 100-ounce contract, MGC as one-tenth of GC, QO as half the GC size, and 1OZ as one ounce. The exchange expanded 1OZ to 24/7 trading in July 2026, which makes its hours materially different from the traditional gold futures schedule.

What changed in 2026: 1-Ounce Gold now trades 24/7

Older gold-futures guides often discuss only GC and MGC. That is now incomplete.

CME's 1-Ounce Gold futures (1OZ) represents one troy ounce and is cash settled to the 100-ounce Gold futures contract. Since July 2026, CME lists it for 24-hour, seven-day trading on Globex, apart from brief scheduled maintenance windows.

That creates a new contract-selection question:

A trader who wants the benchmark contract and deepest flagship market may look first at GC.
A trader who wants smaller unit exposure can compare QO, MGC, and 1OZ.
A trader who specifically needs weekend gold-futures access must distinguish 1OZ from the weekday Globex schedule of the larger contracts.

Do not assume every broker has enabled every contract. CME itself notes that a trader may need to ask a futures broker to enable 1OZ if the symbol is not available on the platform.

How gold futures margin actually works

Futures margin is a performance bond or collateral requirement. It is not the same thing as borrowing half the purchase price of a stock, and it is not a cap on loss.

Three numbers can be different:

Exchange clearing margin — the minimum set through the exchange/clearing framework.
Broker or clearing-firm house margin — a firm may require more than the exchange minimum.
Intraday margin — some brokers may apply a separate lower intraday requirement under their own rules.

Because these values can change with volatility and broker policy, this page intentionally does not publish a permanent "$X is enough to trade gold futures" number.

Before opening a position, check the current requirement for the exact symbol and contract month. CME's 1OZ FAQ explicitly notes that clearing firms may require margin above CME Clearing's minimum.

For the broader margin mechanics, use the dedicated futures margin guide.

A better way to choose a gold futures contract

Instead of choosing the contract with the lowest displayed margin, start with the dollar risk implied by your trade idea.

Suppose your setup would be invalidated if gold moved $8.50 per ounce against you.

Ignoring slippage and fees:

Contract	Ounces	$8.50 adverse move per contract
GC	100	$850
QO	50	$425
MGC	10	$85
1OZ	1	$8.50

The calculation is:

Planned price distance × contract ounces × number of contracts

This is a planning estimate, not a guaranteed maximum loss. A stop order can fill worse than its trigger price in a fast or gapping market, and fees add to the realized result.

The contract should fit the strategy's natural invalidation distance. Shrinking a technically reasonable stop just to make a larger contract fit the account reverses that logic.

Step-by-step: how to trade gold futures

1. Decide whether you actually need futures

Gold exposure can also come from physical metal, exchange-traded products, mining shares, spot/CFD products where permitted, or options. Futures add standardized contract sizes, expiration, exchange clearing, and leverage.

If the question is broader than futures, start with the guide to trading gold across different instruments.

2. Choose the contract size

Compare GC, QO, MGC, and 1OZ using the dollar impact of a normal move for your setup.

A one-ounce contract and a 100-ounce contract may track the same underlying gold market, but they do not create the same account-level P&L.

3. Check the exact contract month and specification

Do not trade a futures symbol as if it were a perpetual asset.

Confirm:

the contract month,
last trading day,
settlement or delivery method,
current trading hours,
tick size,
current volume/liquidity for the month you plan to trade.

GC's trading termination is tied to the delivery month. 1OZ has its own listing and expiration rules. Use the current CME contract specification rather than memorizing a date from an article.

4. Check current margin, fees, and broker availability

Before placing an order, verify the broker's current:

initial and maintenance margin,
intraday margin policy if applicable,
commissions and exchange/regulatory fees,
liquidation policy,
supported gold futures symbols.

These are account- and broker-specific inputs. They should not be replaced by a universal account-size recommendation.

5. Define entry, invalidation, and position size

Write the setup before the order.

For example:

Entry:        4,000.00
Invalidation: 3,991.50
Distance:        8.50 per ounce

The same $8.50 distance creates very different contract-level exposure:

GC:  8.50 × 100 oz = $850
MGC: 8.50 × 10 oz  = $85
1OZ: 8.50 × 1 oz   = $8.50

Then decide whether the resulting exposure fits your own risk limit. Do not start with a desired number of contracts and work backward to an arbitrary stop.

6. Choose the order type deliberately

A market order prioritizes execution over price. A limit order controls the worst acceptable limit price but may not fill. A stop order becomes active only after its trigger condition and does not guarantee the eventual fill price.

For the mechanics, see market, limit, and stop orders explained.

7. Manage the position and expiration

If the trade is intended to be short term, know when the contract approaches its final trading and settlement/delivery window well before that date.

A continuous futures chart can hide the fact that the underlying tradable contract changes over time. If you hold longer, you may need to close or roll from one month to another. The dedicated futures expiration and rollover guide covers that process.

Gold futures vs XAUUSD: do not treat them as the same instrument

A common research mistake is to use "gold," "XAUUSD," and "gold futures" interchangeably.

They are related, but they are not identical.

Topic	COMEX gold futures	Spot/OTC XAUUSD
Contract	Standardized futures contract	Broker/dealer OTC product
Contract month	Yes	Usually no futures-style expiry
Clearing	Centrally cleared futures	Depends on provider/venue
Position size	Exchange-defined contract units	Broker-defined sizing
Margin	Futures exchange/broker framework	Provider-specific
Price series	Individual futures months / continuous chart	Spot/OTC feed

A historical XAUUSD chart can still help with candle-reading or event review, but it cannot reproduce COMEX contract-month behavior, futures margin, order-book liquidity, roll effects, or settlement.

ChartMini is useful for historical chart-reading practice; it is not a COMEX execution simulator and should not be used to infer futures fills or exchange margin.

What moves gold futures prices?

Gold futures respond to the gold market, but no single indicator is a reliable "leading signal."

Common variables traders monitor include:

U.S. monetary-policy expectations and interest rates,
inflation data and real-yield expectations,
U.S. dollar moves,
geopolitical and financial-stress events,
central-bank and investment demand,
positioning and liquidity around major scheduled releases.

The practical point is not that one variable always moves gold in the opposite direction. Relationships change by regime. A trading rule should be tested on the market and time period it claims to describe.

Common gold-futures mistakes

Treating margin as maximum risk

Posting $X of margin does not mean $X is the most the position can lose. P&L continues to change with the futures price until the position is closed or otherwise settled.

Using stale contract specifications

Contract families and trading hours change. In 2026, the expansion of 1OZ to 24/7 trading made many older "GC vs MGC only" explainers incomplete.

Comparing contracts by margin alone

A lower margin number does not tell you whether a contract fits your stop distance, holding period, liquidity needs, or execution plan.

Testing futures execution on a spot-gold chart

A spot XAUUSD replay does not contain the same contract-month, roll, futures order-book, or settlement information as COMEX futures.

Ignoring the contract month

The symbol family is not enough. You need to know which expiration you are actually trading and how close it is to termination.

FAQ

What is the smallest CME gold futures contract?

As of September 2026, 1-Ounce Gold futures (1OZ) represents one troy ounce, or 1/100 of the 100-ounce GC contract. CME lists it for 24/7 trading subject to maintenance windows.

What is the difference between GC and MGC gold futures?

GC represents 100 troy ounces. MGC represents 10 troy ounces, or one-tenth of GC. A $1-per-ounce move therefore changes one GC contract by about $100 and one MGC contract by about $10 before fees and execution effects.

How much money do I need to trade gold futures?

There is no durable universal dollar answer. You need to satisfy the current broker/clearing margin for the chosen contract and still have enough risk capacity for the planned trade. Margin changes over time, and a broker may require more than CME Clearing's minimum.

Do gold futures trade 24/7?

Not all gold futures use the same schedule. CME's 1-Ounce Gold futures now trade 24/7 subject to scheduled maintenance. The flagship GC and other traditional gold futures are generally available nearly 23 hours per weekday trading day from Sunday through Friday.

Can I get physical gold from a gold futures contract?

Settlement differs by product. GC is a deliverable contract, while 1OZ is cash settled to the 100-ounce Gold futures contract. If you do not intend to participate in delivery or settlement, understand the contract's rules and close or roll in accordance with your broker's policy before the relevant deadlines.

Is Micro Gold better for beginners?

MGC's 10-ounce size reduces the dollar impact of each gold-price move compared with GC, but that alone does not make a trade appropriate. Contract choice should be based on the setup's price risk, current margin, liquidity, costs, and your own risk limits.
