Micro Gold Futures: MGC vs GC vs 1-Ounce Gold Compared

Category: Market Education

Compare micro gold (MGC), standard gold (GC) and 1-Ounce Gold futures: tick values, margin, liquidity, trading hours, and which contract fits your account.

Gold futures used to be a big-account market. The standard COMEX contract (GC) controls 100 troy ounces — at recent prices, a notional value well into six figures — and moves $10 for every ten-cent tick. A $30 day in gold is $3,000 per contract. For most retail traders, that is not a position, it is a bet.

CME now lists gold in three sizes: standard GC, Micro Gold (MGC) at one-tenth the size, and 1-Ounce Gold (1OZ) at one-hundredth. This guide compares all three and shows how to pick the right one for your account and strategy. For setups, drivers, and session behavior in gold itself, read our gold futures trading strategies guide first.

The three gold contracts side by side

GC and MGC share the same ten-cent tick, so every chart level and stop distance translates directly between them — one MGC tick is simply $1 instead of $10. 1OZ is the newest and smallest, and its round-the-clock schedule is a genuine structural difference: it can trade on weekends, when GC and MGC are closed.

What gold's daily range means in dollars

Gold's daily range expands sharply around U.S. inflation data, FOMC decisions, and geopolitical shocks. Ranges of $20–$60 are ordinary in active periods. Here is what a single adverse move costs in each contract:

• $10 against you: GC = $1,000, MGC = $100, 1OZ = $10
• $25 against you: GC = $2,500, MGC = $250, 1OZ = $25
• $50 against you: GC = $5,000, MGC = $500, 1OZ = $50

With a $25,000 account and a 1% risk rule ($250), GC only permits a $2.50 stop on one contract — well inside gold's normal noise. MGC permits a $25 stop on one contract or a $12.50 stop on two. That difference decides whether your stop sits at a real structural level or at a random point your account happens to afford. See our guide to position sizing and risk of ruin for the math.

Margin and capital requirements

Exchange margins move with volatility, and gold's big 2024–2026 rally pushed notional values — and margins — up. As a rule of thumb, MGC margin runs about one-tenth of GC margin. Broker day-trading margins can be much lower than exchange overnight margins for both contracts.

Ignore the margin number when sizing. It tells you what your broker will let you hold, not what you can afford to lose. Size from your stop distance and risk budget. Our explainer on futures margin requirements covers the difference between initial and maintenance margin.

Liquidity: why GC still sets the price

GC is the price-discovery contract. MGC trades actively but with a thinner order book, and market makers price it off GC. 1OZ is newer still, and its liquidity is building. Practical implications:

1. Read order flow on GC. Volume profile, footprint, and depth-of-market signals are more informative from GC. Execute in MGC if that fits your size.
2. Expect slightly wider spreads in MGC during fast markets — CPI releases, FOMC statements, and overnight geopolitical headlines.
3. Be careful with 1OZ on weekends. 24/7 access does not mean deep liquidity at 3 a.m. Saturday. Thin books can print sharp moves on small orders.

For 1–20 MGC contracts during the London and New York overlap, fills are generally clean. Execution quality matters most for stop orders in fast markets. Our order execution optimization guide covers how to handle thin books.

Commissions: ten micros are not one standard

Fees are charged per contract, and micro fees are not one-tenth of standard fees. Ten MGC equal one GC in exposure but typically cost two to four times as much in round-turn commissions and exchange fees.

If you consistently trade 10 or more MGC, price out a move to GC. If you trade 1–5 MGC, the sizing flexibility usually outweighs the fee drag. For scalpers the math matters most — fee drag scales with trade count.

Which contract fits which trader

Choose MGC if:

• Your account is under roughly $100,000 and GC sizing would force stops inside gold's normal noise.
• You want to scale in and out of positions in increments.
• You are forward-testing an automated strategy with real fills before committing size.
• You trade a prop firm evaluation with contract caps. See our prop firm evaluation guide.

Choose GC if:

• Your consistent size would be 10+ MGC.
• You trade calendar spreads or need the deepest book for large orders.
• You use depth-of-market scalping where queue position in the price-discovery contract matters.

Consider 1OZ if:

• You want very small exposure — hedging a small physical holding, or learning gold with minimal risk.
• You specifically want to react to weekend news before Sunday's open, and you accept thin weekend liquidity.

What moves gold — the short version

All three contracts respond to the same drivers. Knowing them tells you when to trade and when to stand aside:

• Real interest rates. Gold pays no yield, so falling inflation-adjusted yields tend to support it and rising real yields tend to weigh on it.
• The U.S. dollar. Gold is priced in dollars; a weaker dollar often lifts gold, though the relationship breaks down at times.
• Central bank buying. Official-sector purchases were a major support in recent years.
• Risk shocks. Geopolitical escalations tend to produce fast safe-haven bids, often overnight.
• Scheduled data. CPI, PCE, nonfarm payrolls, and FOMC decisions reliably expand the range. Our economic calendar trading guide covers how to plan around them.

Three MGC setups worth testing

1. London–New York overlap momentum

Gold's most active window typically runs from the U.S. morning session (roughly 7:00 a.m. CT) through late morning. Mark the overnight high and low; trade a 15-minute close beyond either extreme in the direction of the break, with a stop back inside the range. MGC lets you size this correctly even when the overnight range is wide.

2. Post-data retracement

After CPI or payrolls, gold often makes an initial spike, then retraces part of it. Wait for the first 5-minute bar after the release to close. If price reverses through the midpoint of that bar, trade the retracement toward the pre-release price, with a stop beyond the spike extreme.

3. Silver-confirmation trend filter

Gold and silver usually trend together. Take MGC trend entries only when silver (SI) is moving the same direction on the same timeframe — the filter can cut signals that fail on one-metal noise. Our silver futures guide covers the relationship.

Automating micro gold

• Signal from GC, execute on MGC when your platform supports multiple data series in one strategy.
• Build a news blackout around CPI, payrolls, and FOMC unless the strategy is designed for news.
• Use ATR-based stops. Gold's volatility regime shifts dramatically; fixed tick stops that fit a quiet month fail in a volatile one. See our ATR stops guide.
• Roll deliberately. GC and MGC concentrate liquidity in the even-month active contracts (February, April, June, August, October, December). Roll before first notice day, especially since both are physically settled.
• Daily loss cap. Let the algo shut itself off after a fixed dollar loss.

Worked example: one trade, three contracts

Account: $40,000. Risk per trade: 1% = $400. Setup: long gold at a support shelf with a structural stop $18 below entry.

• GC: $18 × 100 oz = $1,800 risk per contract. Not sizeable — 4.5× the budget.
• MGC: $18 × 10 oz = $180 per contract. $400 ÷ $180 = 2 contracts ($360 risk).
• 1OZ: $18 × 1 oz = $18 per contract. 22 contracts — precise, but the fee load on 22 contracts is heavy.

MGC is the practical answer here: on budget, manageable fees, and two contracts allow a partial exit at the first target.

Gold's session map

Gold trades nearly around the clock, but activity is uneven. Knowing the rhythm helps you choose when a micro position makes sense:

• Asian session (evening CT): generally quieter, with occasional moves on Chinese demand or regional headlines. Our overnight Globex strategies guide covers this window.
• London open (around 2:00 a.m. CT): volume picks up, and the London price-setting process can create short bursts of directional activity.
• New York morning (roughly 7:00 a.m. CT onward): typically the most active window, especially on U.S. data days at 7:30 a.m. CT.
• Afternoon: activity tapers after the COMEX settlement window; FOMC days are the exception.

Many traders confine MGC strategies to the London–New York overlap and stand aside overnight, where thinner micro liquidity amplifies slippage.

Backtesting on GC data, trading MGC

MGC's history is shorter and its volume lower than GC's. A reasonable workflow is to research on GC data — longer history, cleaner volume profile — and then validate on MGC data to confirm the fills and fees you should expect. Adjust the commission model to MGC's per-contract fees before trusting any result. Differences in results between the two data sets usually point to slippage or fee assumptions that need fixing.

Common mistakes with micro gold

• Over-trading because ticks feel cheap. Keep the same daily trade cap you would use on GC.
• Holding through first notice day. MGC is physically settled. Most brokers force-liquidate ahead of it, sometimes at poor prices.
• Treating 1OZ weekend prices as signals. A thin weekend print may not survive the Sunday open when GC liquidity returns.
• Ignoring fees in backtests. Model micro commissions accurately or backtest results may overstate what live trading delivers.

Gold in a micro portfolio

MGC pairs naturally with equity-index micros. Gold's drivers — real yields, the dollar, and safe-haven demand — often diverge from stock-market risk, so adding it may smooth a portfolio's equity curve. Traders often build a micro portfolio of MES or MNQ, MGC, and MCL to spread risk across three distinct drivers. Our MES vs MNQ guide covers the index side.

Journal every gold trade

Log each MGC trade with the session, whether data was scheduled, stop distance in dollars, and slippage. Patterns show up fast: many traders find their gold results depend heavily on time of day. NocNoe's trade journal and AI coach surface those patterns automatically, and NocNoe algos handle sizing, stops, and rolls. Compare NocNoe plans to get started.
