What Is XAUUSD? A Beginner's Guide to Trading Gold
If you join any forex group today, you will see one symbol more than any other: XAUUSD. It is the price of one troy ounce of gold in US dollars, and it is the main market we cover at IDL Capital. This guide explains what you are actually trading when you buy or sell it.
What the symbol means
Currency codes follow an international standard. XAU is the code for gold (the "X" marks a commodity rather than a country, and "AU" comes from aurum, the Latin word for gold). USD is the US dollar. So XAUUSD is read as "gold priced in dollars". When the chart shows 4,150.00, one ounce of gold costs 4,150 dollars.
Your broker may add a suffix, such as XAUUSD.s, XAUUSDm or GOLD. These are the same market on a different account type. Always check which symbol your account uses before placing a trade.
How gold is quoted
Gold is quoted with two decimal places. A move from 4,150.00 to 4,151.00 is a move of one dollar. Traders describe this distance in different ways, which causes a lot of confusion:
- Points or dollars: 4,150.00 to 4,151.00 = 1 point, or $1.00.
- Pips: many traders and brokers call $0.10 one pip on gold, so that same $1.00 move is 10 pips. Others call $0.01 a pip. There is no single standard.
To avoid mistakes, we describe gold moves in price terms. "Stop loss 5.00 below entry" means five dollars of price, whatever your broker calls it.
What one lot of gold is worth
On most brokers, 1 standard lot of XAUUSD = 100 ounces. MetaTrader shows this in the symbol details as "contract size 100". That means:
| Position size | Ounces | Value of a $1.00 move |
|---|---|---|
| 1.00 lot | 100 oz | $100 |
| 0.10 lot | 10 oz | $10 |
| 0.01 lot | 1 oz | $1 |
This is why gold can feel dangerous. Gold often moves $20 to $40 in a single day. With 1.00 lot, a $30 move against you is a $3,000 loss. Position size matters more than anything else, and we cover it step by step in how to calculate lot size for gold.
What moves the gold price
Gold reacts to a handful of big drivers:
- The US dollar. Gold is priced in dollars, so a stronger dollar often pushes gold lower, and a weaker dollar often pushes it higher.
- Interest rates and inflation. Gold pays no interest. When real interest rates rise, holding gold becomes less attractive, and the opposite is also true.
- Risk sentiment. In times of fear, such as wars, banking stress or market crashes, investors often buy gold as a safe haven.
- US economic data. Releases like Non-Farm Payrolls (NFP), CPI inflation and Federal Reserve decisions regularly cause sharp moves within seconds.
- Central bank buying. Large purchases by central banks support demand over the longer term.
Why traders like gold, and why it is risky
Gold is popular because it moves a lot and trends clearly when a driver takes over. The same volatility is the danger. Spreads widen around news, price can jump through your stop loss, and a position that is too large can wipe out an account in one session.
Before trading gold with real money, make sure you can answer three questions for every trade: where is my entry, where is my stop loss, and how much will I lose if the stop is hit? If you cannot answer the last one in dollars, the position is not ready.
Key takeaways
- XAUUSD is the price of one ounce of gold in US dollars.
- One standard lot is usually 100 ounces, so every $1.00 move is worth $100 per lot.
- Describe distances in price ($5.00), not pips, to avoid confusion between brokers.
- The dollar, interest rates, risk sentiment and US news drive most big moves.
