Gold is where sizing mistakes are most expensive, because brokers disagree about what a pip is and the contract is 100 ounces. Fix those two numbers and the rest is ordinary risk maths.
XAU/USD is one troy ounce of gold priced in US dollars, and a standard contract is 100 ounces. A $1.00 move is $100 per standard lot, a $0.10 move is $10 and a $0.01 move is $1 - brokers disagree about which of those they call a pip. Gold is driven mainly by real interest rates, the US dollar and safe-haven demand.

One pip = 0.1 of price. A standard lot is 100 troy ounces, so pip value = pip size × contract size × lots. Figures assume a USD account; confirm the contract size with your broker.
A professional charting terminal with a coach built in - the Mirror Desk helps you document, forward-test and encode your own edge as an indicator, from your own trade log. It is a tool for your process, not a signal service and not a promise of results. It is a free preview of the real desk, and a free guest account is required to open it: put in your email, we send a login code, and you are on a live chart in under a minute. The preview runs real market data with one indicator at a time - nothing is saved and no broker is connected. A preview of the product, not advice.
Open XAUUSD on the live desk (H1) → See what the desk does →A standard gold contract is 100 troy ounces, so every $1.00 of price is $100 per lot. Where people get hurt is the word "pip": some platforms call $0.10 a pip, others $0.01, and a few show points. Check your specification, set it in the gold pip calculator, and the tenfold error disappears.

Gold's daily range in dollars is large compared with a currency pair, so the honest output of any sizing calculation is usually a much smaller lot than traders expect. That is the tool working. For the full walkthrough see gold trading for beginners.

It depends on the broker: some call $0.10 one pip, others $0.01. On a 100-ounce contract those are $10 and $1 per standard lot respectively.
A standard XAU/USD contract is 100 troy ounces, so a $1.00 price move is $100 per lot. Some brokers offer 10-ounce or 1-ounce contracts.
Real interest rates, the US dollar, safe-haven demand and longer-term central bank buying.
Usually a pip convention or contract size mismatch, or a stop sized for a currency pair rather than gold's wider range.
