XAUUSD vs GC Futures: Which Should You Chart?

Two markets for one metal

XAUUSD is spot Gold. It is an over-the-counter market: banks, liquidity providers and brokers quote prices to each other and to clients, and there is no central exchange where every trade prints. When you open an XAUUSD chart on TradingView, you are looking at one provider’s quote stream — OANDA’s, or another broker’s. Two XAUUSD charts from two providers will agree on the big picture and disagree on details: the exact tip of a wick, the spread during a news release, the price at which the daily candle closes.

GC is the Gold futures contract traded on COMEX, part of CME Group. It is a standardized contract for 100 troy ounces, traded on a central order book, with a smaller Micro contract (MGC) for 10 ounces. Every trade goes through the exchange, so there is one tape, one official volume number, and one set of highs and lows for everyone. The trade-off is that futures expire: each contract has a delivery month, and the market’s attention moves from one contract to the next through the year.

Both track the same underlying metal and move together tick for tick in any way that matters for direction. The differences are in the plumbing — and four of them matter for a day trader.

Difference 1: the price is not the same number

GC normally trades above spot. The gap, called the basis, reflects the cost of carrying Gold until the contract’s delivery date — mostly interest rates, plus storage and insurance. The further away the delivery month and the higher the rates, the wider the gap; as expiry approaches, the futures price converges toward spot.

Practically, this means a level is not portable between the two charts. A prior-day high marked on GC is not at the same dollar price as the prior-day high on XAUUSD, and the offset is not constant: it shrinks as the contract ages and jumps when the market rolls to the next one. If you read a level in one place and execute in another, translate it by the current gap, not by a number you remember from last month.

Difference 2: real volume vs tick volume

This is the one that changes what your indicators measure.

On GC, volume is the number of contracts that actually changed hands, reported by the exchange. On spot XAUUSD there is no central tape, so TradingView shows tick volume: the number of price updates in the provider’s feed during the bar. It counts how often the quote changed, not how much metal traded.

Tick volume is not useless. Quotes update more often when the market is active, so it works as a proxy for activity. It is what our own volume-by-hour study uses, and we label it as such: across 653 normal days, the hours starting 15:00 and 16:00 Paris carried 8.4% and 8.5% of the day’s tick volume, 14:00 carried 6.5%, and the London open hour at 09:00 carried 4.5%. On the 119 data days in the sample, 14:00 rose to 10.7% and 15:00 to 10.5%. Those are shares of a day’s activity — a question a proxy can answer reasonably well. The full breakdown is in our hour-by-hour volume study.

What a proxy cannot do is tell you how much traded at a given price. That limits three families of tools:

Two honest notes on that table. First, delta on a TradingView chart is an approximation on either instrument — it is inferred from lower-timeframe bars, not read from the order book — but it is a better-grounded approximation when the volume underneath is real. Second, an activity-weighted VWAP on spot is still a usable line. It behaves sensibly, and everything we measured about band touches — 6,945 of them over 830 days — was measured on spot. It is simply not the VWAP that a futures execution desk is benchmarked against. We explain the weighting in detail in the session-anchored VWAP guide.

Difference 3: futures expire, spot does not

A spot chart is one continuous series. A futures chart is a sequence of contracts glued together.

Liquidity in Gold futures concentrates in a handful of delivery months — February, April, June, August and December are the ones that carry the volume. As one approaches delivery, traders move to the next, and the “front month” changes. The symbol most people chart, the continuous contract (GC1! on TradingView), stitches those contracts into a single line.

The stitching has consequences:

• Roll gaps. The new contract trades at a different price than the old one, because its delivery date is further away. On an unadjusted continuous chart, that shows up as a jump that never traded.
• Back-adjustment. TradingView can adjust historical prices to remove the jump. That repairs the shape of the chart and shifts old price levels away from where they actually printed. Both settings are defensible; you need to know which one you are looking at.
• Volume around the roll. For a few days, activity is split between two contracts. Volume on the front month fades while the next one builds, and a volume profile spanning the roll mixes the two.

For intraday work within a single week, none of this bites. For anything that compares today with months of history — a composite profile, an anchored VWAP from a swing low three months back, a multi-year statistic — it does.

Expiry itself also generates folklore, the best-known being that options expiration pins Gold to round numbers. We tested it over 39 COMEX expirations: the close landed within $10 of the nearest $50 level 25.6% of the time on OPEX days versus 35.1% on normal days, and OPEX day ranges were 0.85× ATR — slightly quieter, nothing special. The pin theory is not supported by that sample.

Difference 4: the day does not start at the same time

Both markets trade nearly around the clock from Sunday evening to Friday evening, New York time. But “the day” is defined by the feed, not by the metal. Futures have an exchange-defined session with a daily maintenance break. Each spot provider sets its own daily rollover, and they do not all agree.

This matters more than it sounds. The prior-day high, the prior-day low, the daily open and any daily-anchored VWAP all depend on where the day boundary sits. Move the boundary and some of those levels move with it. Two traders who both say “price swept the prior-day low” may be looking at two different prices, each correct on its own chart.

The same goes for wicks. A spot provider’s spread widens in thin hours and around releases, which can stretch a wick on that feed and not on another. In our Fair Value Gap study of 55,739 five-minute gaps on spot, three in ten were narrower than about $0.25 — spread territory. At that scale, the feed you chose is part of the pattern.

So which one should you chart?

Start from what you trade, not from what looks more professional.

If you trade spot or a CFD through a broker: your fills, your stops and your liquidations happen at your broker’s prices. Chart the feed closest to your execution for anything involving levels, stop placement and sweeps. A wick that exists only on the futures chart did not take you out; a wick that exists only on your broker’s feed did.

If you trade GC or MGC: chart the futures contract you are in. Your levels, your volume and your fills all come from the same tape, which is the cleanest situation available. Check whether your data is real-time — on TradingView, exchange futures data is delayed unless you subscribe to the exchange feed — and decide deliberately whether you want back-adjustment on or off.

If volume is part of your method and you trade spot: run two charts. Keep XAUUSD for execution-side levels and open GC alongside it for profile, delta and volume-weighted VWAP. Read structure from the futures volume (where the value area is, whether a breakout carried participation) and translate levels across by the current gap between the two prices.

If your method is price and time only — sessions, prior-day and prior-week levels, ranges, regime — either chart does the job. Pick the one you execute on and stay consistent. Consistency matters more than the choice: a backtest made on one feed and traded on another has a small, silent mismatch built into every level.

For the tools themselves, the split is straightforward. Level and range tools such as Liquidity Levels or Range & ADR Tracker are built on price and time, so the choice of instrument changes where their levels sit, not what they measure. Volume Profile - Intraday, Anchored Volume Profile + Traps, CVD Pro and VWAP Session Bands take whatever volume the chart gives them: on GC that is traded contracts, on spot it is tick volume. RVOL Time-of-Day compares a feed with its own history at the same hour, which is why it holds up on a proxy. And Gold COT Positioning is a futures-market dataset by nature: the report it reads describes positions in COMEX Gold futures, whichever chart you display it on.

What this means for our own numbers

Every statistic on this blog was measured on XAU/USD spot data from Dukascopy — not on futures. The sweep study covers 2,434 sweeps over 807 days; the VWAP work covers 830 days; the volume-by-hour study uses tick volume and says so. We chose spot for a reason that follows from everything above: one continuous series, no rolls, no adjustment decisions hidden in the history.

That choice has a cost, and we list it in the limits of each study: spot is not futures. A frequency measured on one provider’s spot feed should be close on GC, because the two markets move together — but “should be close” is an expectation, not a measurement. Day boundaries differ, wicks differ, and the basis moves levels around. If you trade futures and want to rely on a number we publish, check it on your own chart first. The definitions are published so that you can: how a sweep is defined, where the day starts, which horizon is used. Our sweep study spells out each of those choices, and they are the first thing to match before comparing your numbers with ours.

A five-minute check on your own chart

1. Read the full symbol. The prefix tells you the source: a broker name means a spot quote stream, COMEX means the exchange.
2. Look at the volume label. On a spot symbol, treat it as tick volume, whatever the axis says.
3. On futures, check the contract. Continuous or a specific month? Back-adjusted or not? Real-time or delayed?
4. Compare one known level. Put yesterday’s high on both charts and note the gap. That is today’s translation between the two.
5. Match the chart to the account. Levels and stops come from the instrument you execute on. Volume context can come from the other one.
