How to Trade Gold (XAU/USD): A Practical Guide

Gold trades differently from currencies, and traders who arrive from forex often size a gold position the way they would size EUR/USD. That is the mistake this guide exists to prevent.

You will not find a price here. Prices change while you read and any number printed on a page is wrong by the time you see it. What follows is the mechanics: what moves gold, how a gold CFD is priced, what a contract is worth in money, what it costs to hold, and when the market is actually active.

The mechanics of CFDs themselves are covered separately. This guide assumes you know how a leveraged position opens, closes and settles.

What XAU/USD actually means

XAU is the ISO code for one troy ounce of gold. USD is the US dollar. Put together as XAU/USD, the quote reads exactly like a currency pair: the number of US dollars that one troy ounce costs.

Two consequences follow, and both matter more than they first appear.

Gold is quoted in dollars, so dollar strength affects it directly. When the US dollar strengthens against everything else, gold priced in dollars tends to fall even if nothing about gold itself has changed. Part of every gold move is a dollar move wearing a different label.

A troy ounce is not an ounce. A troy ounce is about 31.10 grams against roughly 28.35 for the ordinary ounce. This matters only for converting to physical quantities, but it explains why gold weights never quite match intuition.

What moves the gold price

Gold pays no interest, produces no earnings and has no cash flow. Its price is set by what people are willing to hold it instead of.

Real interest rates

This is the dominant long-run driver. The real interest rate is the nominal rate minus expected inflation, and it represents the return you give up by holding an asset that yields nothing.

When real yields rise, holding gold becomes more expensive in opportunity terms and demand tends to weaken. When real yields fall, the cost of holding gold falls with them. This relationship is not mechanical and it breaks down for months at a time, but over longer periods it explains more of gold's behaviour than any other single factor.

Practically, this means gold reacts strongly to anything that changes the expected path of interest rates: central bank decisions, inflation data, and employment data that feeds into rate expectations.

The US dollar

Because gold is priced in dollars, dollar strength and gold usually move in opposite directions. The relationship is loose rather than fixed, and there are periods where both rise together, typically when investors are buying dollars and gold simultaneously as defensive assets.

Central bank buying

Central banks hold gold as reserves, and their buying and selling moves in slow, large blocks. This demand is price-insensitive in a way that private demand is not, since a reserve manager diversifying does not stop because the price rose last week. Reported reserve changes are published with a lag, so this shows up as a persistent background bid rather than as a tradeable event.

Risk sentiment

Gold has a long-standing role as a defensive holding, and it often catches a bid during periods of financial stress or geopolitical uncertainty. The behaviour is inconsistent enough that treating it as a rule will cost you money. In some crises gold rises immediately, and in others it falls first as investors sell whatever is liquid to meet margin calls elsewhere, then recovers afterwards.

Physical and investment demand

Jewellery fabrication, industrial use and investment products all contribute. Jewellery demand carries seasonal patterns tied to wedding and festival seasons in the largest consuming markets. Exchange-traded product holdings shift with investor sentiment and are reported regularly. These influence the medium-term picture rather than the intraday one.

How a gold CFD is priced

A gold CFD does not track a single official price. Understanding what sits behind the quote explains several things that otherwise look like broker error.

The underlying is over-the-counter spot gold. The reference market is unallocated gold held in London, traded between bullion banks and large participants. There is no central exchange for spot gold in the way there is for equities.

The LBMA benchmark is a reference, not the live price. The LBMA Gold Price is set through electronic auctions administered by ICE Benchmark Administration, running at 10:30 and 15:00 London time. Those auctions produce the AM and PM benchmark prices used for settlement and valuation across the industry. They are not published on weekends or UK bank holidays. Your CFD quote moves continuously and does not stop at the auction price, though the auction periods themselves often bring a burst of volume.

Futures influence the quote. COMEX gold futures carry enormous volume and their pricing feeds back into spot. Futures trade at a small premium or discount to spot reflecting storage and financing, so the two are related without being identical.

The broker aggregates and marks up. Your quote comes from the broker's liquidity providers with a spread applied. This is why the price on your platform differs slightly from a price you see quoted elsewhere, and why the difference widens when liquidity thins.

Contract and lot sizes

This is where forex habits cause real damage, so work through the numbers rather than skimming them.

A standard gold lot is 100 troy ounces. One contract therefore represents 100 ounces of exposure.

The arithmetic that follows:

Now compare that to a currency pair. One standard lot of EUR/USD is 100,000 units, and a one pip move is worth about US$10. One standard lot of gold moves US$100 for every dollar of price change, and gold routinely moves ten or twenty dollars in a session.

A trader who opens one lot of gold because one lot of EUR/USD felt manageable has taken on a position that behaves very differently. Gold's daily range in dollar terms is frequently many multiples of what an equivalent forex position would produce.

Two practical rules follow:

1. Size gold positions from the dollar value of your stop distance, not from lot count. Decide the maximum you are willing to lose, divide by the value per dollar of movement at your intended size, and check that the resulting stop distance makes sense against gold's normal range.

2. Check your broker's contract specification rather than assuming. Contract sizes and minimum increments vary between firms, and some quote gold in different units entirely.

Margin. Under ASIC's product intervention order, gold sits in a lower leverage band than major currency pairs, so a gold position ties up proportionally more margin than a same-notional forex position. Confirm the current cap and your broker's margin requirement before sizing.

Spread and overnight funding

Spread. Gold spreads are quoted in dollars and cents rather than pips, and they are wider than major currency pairs in percentage terms. They vary considerably through the day, tightening during London and New York overlap and widening in the thin hours around the daily rollover.

Because a gold spread of, say, 30 cents costs US$30 on a standard lot, the cost of entry is meaningful. Short-horizon gold trading is expensive relative to major forex for exactly this reason.

Overnight funding. Gold positions are financed like any other leveraged position and are charged or credited each night held. Two features catch people out:

• The charge is calculated on the full notional value, which for a 100-ounce contract is substantial.

• Weekend financing is usually applied as three days on a single midweek night, so a position held across a weekend attracts a larger charge than a weekday night.

Long gold positions typically pay financing, while short positions may pay or receive depending on prevailing rates. Check the swap table for the specific instrument on your account rather than assuming direction.

For a multi-week gold view, financing accumulates into a material part of the outcome. Gold CFDs are structured for shorter horizons.

When gold is most active

Gold trades nearly around the clock on weekdays, but liquidity is far from evenly distributed. Times below are London time, since that is where the physical market clears. Australian traders should convert with care, because daylight saving shifts at both ends of the year and the offset is not constant.

The Asian session. Physical demand from the largest consuming markets sets a tone, and Shanghai pricing gives an early read. Ranges are typically narrower and moves are less impulsive.

The London morning. Liquidity steps up sharply. This is the core of the physical market and the point where overnight positioning gets tested.

The 10:30 auction. The AM benchmark auction concentrates order flow. Volume rises and short bursts of movement are common as participants transact around the benchmark.

The London and New York overlap. The deepest liquidity of the day and the tightest spreads. Most US economic data lands in this window, which makes it both the best time to trade and the most volatile.

The 15:00 auction. The PM benchmark, used widely for valuation and settlement, brings a second concentration of flow.

The late New York session. Liquidity drains away, spreads widen, and the daily rollover applies financing.

Two scheduled event types dominate gold's biggest moves: US inflation data and US central bank decisions. Both land during the overlap, and both can produce a move larger than a typical full day's range within minutes. Spreads widen in the seconds before these releases as liquidity providers withdraw quotes.

Practical points before you place a gold trade

• Check the weekend gap risk. Gold closes and reopens, and news over the weekend can produce a gap that a standard stop cannot protect you inside.

• Set your stop against the level, then size to it. Gold's normal range means a stop placed at a forex-sized distance will be hit by ordinary noise.

• Know the rollover time on your account. It determines when financing applies and it is often when spreads are widest.

• Read the contract specification. Contract size, minimum increment, margin requirement and swap rates all vary by broker.

Frequently asked questions

Is gold a currency pair or a commodity?

Both descriptions are used. XAU/USD is quoted like a currency pair and often sits under FX on trading platforms, while its drivers and its contract specification are those of a commodity. Treat the quote convention as a currency pair and the risk profile as a commodity.

Why is gold quoted in US dollars?

The global bullion market settles in dollars and the London market prices in dollars, so USD pricing is the international convention. Brokers also offer gold against other currencies, though those quotes are less liquid and carry wider spreads.

Does gold always rise when markets fall?

No, and building a strategy on that assumption is a common way to lose money. Gold often gains during periods of stress, but in sharp liquidity events it can fall first as participants sell liquid assets to raise cash, then recover afterwards. The relationship is a tendency rather than a rule.

What is the smallest gold position I can trade?

Most brokers allow fractional lots, commonly down to 0.01 of a standard lot, which is one troy ounce of exposure. The minimum varies by broker and account type.

Why did my gold trade cost so much more than a forex trade of the same lot size?

Because the contract is larger in effect and the spread is wider. One gold lot moves US$100 per dollar of price change against roughly US$10 per pip on a standard forex lot, and gold routinely moves many dollars in a session. Lot count is not a comparable measure across instruments.

Can I hold a gold CFD long term?

You can, but financing accrues nightly on the full notional value and works against a long hold. Investors seeking long-horizon gold exposure generally use instruments without a nightly financing charge.

What time do gold spreads widen most?

Around the daily rollover in the late New York session, when liquidity is thinnest, and in the seconds surrounding major US data releases, when providers pull quotes.

Where can I see the official benchmark price?

The LBMA publishes benchmark information at lbma.org.uk. Note that this is a twice-daily benchmark rather than a live price, so it will not match your platform quote.

Gold is available as a CFD alongside other markets at www.axonmarkets.com.

Risk warning: CFDs are leveraged products and carry a high level of risk. Losses can exceed the margin committed to a position and can consume your entire account balance. Gold is a volatile instrument and a standard contract carries substantial notional exposure. CFDs are not suitable for all investors. Make sure you understand how these products work and whether you can afford the risk of losing your money. This article is educational information only.
