Gold moved $18 in the twenty minutes after a hot US inflation print, more than most currency pairs move in a full session, and a trader sizing gold the same way they size EURUSD found that out with a stop that got run over before it had time to matter. XAUUSD trades in dollars per ounce, not pips, and its typical daily range, often $25 to $40 in calm conditions and considerably more around a major US data release, makes it one of the most rewarding and one of the most punishing instruments on the watchlist depending entirely on whether the trader respects the difference.
What actually moves gold
Gold's price is driven mainly by two forces working together: the direction of the US dollar, since broad dollar weakness tends to lift gold given it is priced in dollars, and real yields, meaning US bond yields adjusted for inflation expectations. When real yields fall, gold gets more attractive relative to interest-bearing assets and tends to rally; when real yields rise, gold typically comes under pressure. A soft US CPI print often moves both drivers the same direction at once, dollar weaker and real yields lower, which is why gold's reaction to US inflation data is frequently sharper than a currency pair's reaction to the same release.
Sizing gold correctly
The pip-value math that works for EURUSD does not transfer directly. On a standard lot of gold, a $1 move is typically worth $100, which means a $100 risk budget, 1% of a $10,000 account, against a $4 stop supports roughly 0.25 lots, quite different from the lot sizes a EURUSD trader is used to. Traders who size gold in round numbers, half a lot, one lot, without running the actual arithmetic often discover their real risk was two or three times what they intended the first time a stop gets hit.
Gold's session character
Gold trades essentially around the clock but its real volatility windows track the same rhythm as forex: quieter through the Asia session, building through the London open around 8 AM London time as European desks get active, and often peaking during the London and New York overlap, especially on days carrying a US data release. Gold also has its own quirk around the London gold fix windows, historically 10:30 AM and 3 PM London time, when benchmark-related flows can produce brief, sharp moves unrelated to any obvious chart pattern.
Silver: gold's louder, less liquid cousin
Silver, XAGUSD, tends to track gold's direction but with noticeably more volatility per dollar of price, since the metal's smaller market means the same dollar flows produce bigger percentage swings. Silver also reacts to industrial demand data in addition to the dollar and yields story that drives gold, giving it a second, less predictable driver. Traders who apply gold's playbook to silver without adjusting stop distance for its larger typical range regularly get stopped out of otherwise correct trades.
Respecting the range before entering
The practical discipline for both metals is checking the recent daily range before setting a stop, not assuming a EURUSD-sized stop transfers over. A $3 stop that would be generous on a quiet EURUSD-style move is tight enough to get clipped by gold's normal noise on an average day, let alone a data day. Widening the stop and sizing down to match, rather than keeping the stop tight and oversizing, is the adjustment that actually respects the instrument's real character.
