XAU/USD Trading Guide: How Gold Behaves for Forex Traders
XAU/USD trading explained: how gold is quoted, what a lot and a pip mean, what moves the price, and why gold needs wider stops and smaller positions.
Gold sits in the same watchlist as EUR/USD and opens with the same buy and sell buttons, so it is easy to treat it as just another pair. Then your first XAU/USD trading position moves $30 in an hour, the lot size means something different and the platform’s idea of a “pip” matches nothing you learned on currencies.
Quick answer: XAU/USD is the price of one troy ounce of gold in US dollars. A lot is often 100 ounces, so 0.10 lots gains or loses $10 per $1 move. Gold tends to fall when US real yields and the dollar rise, and to rise in fear. It swings more than major pairs, so use wider stops and smaller positions.
What is XAU/USD? Gold priced in dollars
XAU/USD is the spot price of gold in US dollars. XAU is the code for gold in the international list of currency codes (ISO 4217), which is why trading platforms can show it in the same format as a currency pair. A price of 4,012.35 means one troy ounce of gold costs $4,012.35. A troy ounce is about 31.1 grams, a little heavier than the ordinary ounce used for food. Prices in this guide are illustrative round numbers, not a forecast.
Strictly speaking, gold is not a currency pair. It is a commodity with a currency code. No country issues it, no central bank sets an interest rate on it, and it pays nothing to hold. When you buy EUR/USD you hold euros that earn the euro rate; when you buy XAU/USD you hold a metal that earns nothing at all. That one difference explains much of how gold behaves, and we will come back to it.
Retail traders usually trade XAU/USD as a CFD or a rolling spot contract, just as they trade currencies. You never receive a bar of metal; you trade the change in price. Underneath, the real market is huge. London is the centre of the physical, over-the-counter trade between banks and bullion dealers, and New York hosts the main gold futures market. Your broker’s price is drawn from that activity.
Gold reacts to the forces forex traders already watch: US interest rates, the US dollar and the market’s mood. It often moves like a currency with no central bank, which makes it a useful safe haven gauge even if you never trade it. Our guide to safe-haven currencies puts gold alongside the dollar, yen and franc; this article is about trading it.
XAU/USD contract size, pips and points
On currency pairs a standard lot is 100,000 units of the base currency. On XAU/USD the base is ounces of gold, and a standard lot is often 100 troy ounces. “Often” matters: some platforms use a different contract size, so open the contract specification for gold on your own platform before you trade. Everything below assumes 100 ounces per lot.
With that contract, the money is simple. Each $1 move in the gold price is worth $1 per ounce you hold:
- 1.00 lot = 100 oz = $100 per $1 move
- 0.10 lots = 10 oz = $10 per $1 move
- 0.01 lots = 1 oz = $1 per $1 move
Because the price is quoted in dollars, these values are fixed in dollars, much like a pip on EUR/USD. If your account is in pounds or euros, the broker converts the dollar result at the current rate.
Why “pip” means different things on gold
On currencies, everyone agrees what a pip is. On gold, they do not. XAU/USD is usually quoted to two decimal places, so the smallest step is one cent, $0.01. Platforms then label that step, or a bigger one, in different ways:
- Many MetaTrader-style platforms call the smallest price step a point, which on a two-decimal gold quote is $0.01. A few price feeds show a third decimal, which shrinks the point again.
- Many brokers describe a pip on gold as $0.10.
- Many traders talk about gold moves in dollars: “gold is up $15”.
So a $5 move can be described as 500 points, 50 pips or $5, depending on who is speaking. None of them is wrong, but mixing them up is how a trader thinks they set a 50-pip stop and actually set one 50 cents away.
The habit that protects you is to think and plan in dollars per ounce: “my stop is $12 away and I hold 5 ounces, so I risk $60.” Then translate into your platform’s units only at the last step. The same discipline applies to any instrument whose pip is unfamiliar, which is why the Academy lesson on pips and lots starts from money, not jargon.
What moves gold: real yields and the US dollar
Two forces do most of the work on XAU/USD over weeks and months, and both come back to the fact that gold pays no interest.
Real yields: the cost of holding gold
A real yield is the interest rate on a bond after inflation. If a US government bond pays 4% and inflation is expected to run at 2%, the real yield is about 2%. Markets watch it directly through inflation-protected US Treasury bonds, known as TIPS.
Gold competes with that bond for the same safe money. When real yields are high, holding gold means giving up a solid, inflation-beating return, so gold tends to struggle. When real yields are low or negative, cash and bonds lose value after inflation, gold’s lack of income stops being a handicap, and it tends to attract buyers.
The link is a tendency, not a law. It held well for much of the 2010s, and in 2022, as the Federal Reserve raised rates quickly and real yields jumped, gold fell for much of the year. But from 2023 gold went on to set new record highs while real yields stayed high, a break that coincided with heavy central-bank buying, which the World Gold Council puts above 1,000 tonnes a year in 2022, 2023 and 2024. Treat real yields as the backdrop, then check whether something bigger is overriding it.
The US dollar
Gold is priced in dollars, so a stronger dollar makes it more expensive for anyone paying in euros, yen or rupees, and a weaker dollar makes it cheaper. As a result XAU/USD tends to move in the opposite direction to the dollar and often in the same direction as EUR/USD. The correlation is loose and can break for months, but when gold and EUR/USD are both rising, you should assume a large part of the move is dollar weakness. Our EUR/USD trading guide explains what drives that side of the story.
US data days
Because real yields and the dollar both react to US inflation and jobs figures, those releases are often gold’s busiest moments. A hotter-than-expected CPI print tends to lift Treasury yields and the dollar, which tends to push gold down; a soft one tends to do the reverse. The mock release below shows the dollar’s reaction on EUR/USD. Read gold the same way round: when EUR/USD falls on a hot number, XAU/USD usually falls with it.
| Time | Cur. | Impact | Event | Previous | Forecast | Actual |
|---|---|---|---|---|---|---|
| 13:30 | USD | ●●● | CPI (inflation, year on year) | 3.2% | 3.1% | — |
A mock US CPI release. Slide the actual figure away from the forecast to see the illustrative reaction in EUR/USD. Gold usually leans the same way: a hot surprise lifts the dollar and yields, which tends to weigh on XAU/USD.
The Academy lesson on inflation and CPI explains how to read the release, and our guide on how interest rates affect currency covers the chain from rate expectations to prices.
Gold as a safe haven, and why central banks matter
The second family of drivers is about fear and about who is buying.
Risk-off: gold usually rises, but not always
In a risk-off move, investors sell shares and higher-yielding currencies and buy the havens. Gold usually joins the havens. It has no issuer that can default, it cannot be printed and it has held value over centuries, so worried investors reach for it, especially when the worry is about inflation, a government or the financial system itself. Gold is not on the map below, but in most fearful episodes it sits with the havens rather than the risk currencies. Switch the mood to see the company it keeps.
Tap a currency to see why it behaves this way.
Risk-on versus risk-off for the major currencies. Gold is not shown, but in most risk-off episodes it behaves more like USD, JPY and CHF than like AUD or NZD.
The exception is a dash for cash. When a shock is sudden and severe, investors sell whatever they can to raise dollars, and gold is easy to sell. In March 2020, as the pandemic hit markets, gold fell by more than 10% in about two weeks before going on to its first close above $2,000 that summer. A haven that pays you nothing can still be sold to meet a margin call elsewhere. The risk-on vs risk-off guide covers how to tell the two kinds of panic apart.
Central-bank buying
The other force is quieter and slower. Central banks hold gold in their reserves, and in recent years many have been adding to them. The World Gold Council’s figures put central-bank purchases above 1,000 tonnes a year in 2022, 2023 and 2024, far more than in the previous decade. That steady demand does not move the price minute by minute, but it helps explain why gold kept rising when real yields said it should not. The lesson on central banks and interest rates covers the other side of central-bank work: setting rates.
Put together, the drivers look like this. Read them as forces pulling on one price, some up and some down, often at the same time.
Two smaller influences are worth knowing. Physical demand for jewellery and bars, especially from India and China, matters over years rather than days. And gold has links to some currencies: Australia is one of the world’s largest gold producers, so the Australian dollar sometimes moves with it, though iron ore matters more, as our guide to commodity currencies explains.
When gold trades: sessions, spreads and swap
On most platforms XAU/USD trades almost around the clock from Sunday evening to Friday evening, with a short pause each day. Like EUR/USD, it is quietest in Asian hours and busiest when London and New York overlap, but gold has a few fixed points of its own. The most important is the LBMA Gold Price, a benchmark auction run twice a day in London, at 10:30 and 15:00 London time, which large buyers and sellers use to price physical gold.
Spreads on gold
The spread on XAU/USD is quoted in dollars and cents per ounce, so compare it in money, not in pips. Multiply the spread by the ounces you trade: a 30-cent spread on 10 ounces costs $3 to open. Like every instrument, gold’s spread widens in the quiet hours, around the daily rollover and in the seconds around big US releases. Our guide to forex trading costs shows how spread, commission and overnight charges add up.
Swap: holding gold overnight
Positions held past the daily rollover, 5 p.m. New York time, pay or earn a swap. On gold it is driven mainly by US dollar interest rates plus the broker’s markup. Economically, a long gold position is like borrowing dollars to hold a metal that pays nothing, so while dollar rates are well above zero, holding long gold overnight usually costs money. A short position may earn a small credit, or may still pay once the markup is taken. Check the swap in your platform’s contract specification, and check which night is charged three times. Our guide to forex swap explains the calculation, and swap-free accounts usually replace swap with a fee rather than removing the cost.
XAU/USD trading volatility: wider stops, smaller positions
Gold moves a lot. A day’s range of around 1% of the price is common, which at an illustrative $4,000 is $40, and on major news days it can be several times that. Over the long run, gold’s percentage swings have typically been larger than EUR/USD’s, often around twice as large. In money terms, 0.10 lots of gold can easily swing by a few hundred dollars in a session.
That has two consequences for XAU/USD trading. First, a stop loss has to sit outside gold’s normal noise, which means further away in dollars than a beginner expects. A $3 stop on gold is like a 2-pip stop on EUR/USD: almost certain to be hit by random movement. Second, because the stop is wider, the position has to be smaller to keep the same money at risk.
How do you decide how wide is wide enough? Use the chart’s structure first: place the stop beyond the swing high or low that would prove your idea wrong, with a buffer for gold’s noise. Many traders then sanity-check the distance against the Average True Range, a measure of typical recent movement; our guide to the ATR indicator shows how. Step through the illustrative chart below to see why a tight stop on gold is often a false economy.
Illustrative XAU/USD chart, not real prices. A $5 stop under support is taken out by an ordinary wick before price rises. A stop beyond the structure, with a smaller position, survives the same noise for the same dollar risk.
Leverage on gold is capped lower
Leverage magnifies gains and losses alike, and regulators treat gold as riskier than major currency pairs. Under the rules the European Securities and Markets Authority introduced in 2018, which the UK kept, retail clients can use at most 1:20 on gold, against 1:30 on major pairs. Australia applies a similar cap. That means a margin of 5% of the position’s value: 10 ounces at $4,000 is $40,000 of gold and needs $2,000 of margin. Leverage only sets what you are allowed to open; the position size you choose sets what you can lose. Our guide to leverage in forex and the lesson on leverage and margin go into the detail.
The same method works for any position: risk in dollars, divided by the stop in dollars, gives the ounces. The lesson on position sizing and our guide to position sizing in forex cover the general formula, and the lesson on stop-loss placement explains how to put the stop where the market proves you wrong.

What would you do?
You hold 0.10 lots of gold, bought at 4,000 with a stop at 3,980. US inflation is due in ten minutes and the forecast is for a slightly softer figure. Your loss if the stop is hit is $200, on a $10,000 account. What do you do?
Common mistakes when trading gold
Using currency lot sizes on gold
A trader used to 0.50 lots on EUR/USD who opens 0.50 lots of gold holds 50 ounces, worth $50 for every $1 move. On an ordinary $40 day that is a $2,000 swing. Always convert lots to ounces first.
Mixing up pips, points and dollars
Setting a “50-pip” stop without knowing whether your platform’s pip is $0.01 or $0.10 can leave the stop ten times closer or further than you meant. Plan in dollars per ounce and convert at the end.
Copying stop distances from currency pairs
Gold’s normal noise is much larger than a major pair’s. A stop that would be sensible on EUR/USD is often inside gold’s ordinary wiggle. Place stops from the chart, then size down to fit them.
Treating gold as a separate bet from the dollar
Long gold, long EUR/USD and short USD/CHF can all be the same bet against the dollar. One strong US data release can hit all three. Count them together, as our guide to currency correlation and the lesson on correlations show.
Assuming gold always rises in a crisis
In a sudden dash for cash, gold can be sold with everything else, as it was for a fortnight in March 2020. A haven tendency is not a hedge you can rely on for a specific trade.
Frequently asked questions
Is XAU/USD a currency pair?
Not strictly. XAU is gold's code in the international currency code list, so platforms quote it like a pair, but gold is a commodity. No country issues it, no central bank sets a rate on it and it pays no interest. It is traded alongside forex because it reacts to the same forces: US rates, the dollar and risk mood.
How much is 1 pip on XAU/USD?
It depends on the platform. Gold is usually quoted to two decimals, and many brokers call $0.10 a pip, while MetaTrader-style platforms call the $0.01 step a point. The safest approach is to count in dollars: with 100 ounces per lot, each $1 move is worth $100 per lot, $10 on 0.10 lots and $1 on 0.01 lots.
What is the lot size for gold?
A standard lot of XAU/USD is often 100 troy ounces, so 0.10 lots is 10 ounces and 0.01 lots is 1 ounce. Some platforms use different contract sizes, so check the contract specification on yours before trading. Getting this wrong is one of the most common and expensive mistakes new gold traders make.
What leverage can I use on gold?
For retail clients in the UK and EU, leverage on gold is capped at 1:20, which means a margin of 5% of the position's value, compared with 1:30 on major currency pairs. Australia applies a similar cap. Professional clients can be offered more, but give up some protections. Leverage magnifies losses as much as gains.
What moves the price of gold the most?
Over weeks and months, US real yields and the US dollar: gold tends to fall when they rise and rise when they fall. Fear usually lifts gold, except in a sudden dash for cash. Central-bank buying has added steady demand in recent years. Day to day, US inflation and jobs data and Fed decisions cause the biggest moves.
When is the best time to trade XAU/USD?
Gold is usually most active during London hours and the London–New York overlap, when US data is released and both big markets are open. Asian hours tend to be quieter, with wider spreads. The London auctions at 10:30 and 15:00 and Fed decisions can also bring bursts of activity. Choose active hours you can actually be present for.
