| Pair | Typical Spread (pips) | Spread as % of ATR (H1) |
|---|---|---|
| EURUSD | 0.1 - 0.5 | ~0.5% |
| GBPUSD | 0.5 - 1.5 | ~1.5% |
| USDJPY | 0.2 - 0.8 | ~1% |
| XAUUSD | 2 - 10 | ~3-5% |
On XAUUSD, a 5-pip spread on a 20-pip SL means you are paying 25% of your risk just to enter the trade. That is not workable. You must widen stops proportionally — typical XAUUSD stop losses are 50-150 pips (not 20-30 like on forex pairs) to keep the spread-to-risk ratio reasonable.
EURUSD H1 average true range: ~15-25 pips. XAUUSD H1 ATR: ~$3-8 (which is 30-80 in pip-equivalent terms). A 20-pip stop loss — completely normal on EURUSD — gets hit within 2-3 candles on XAUUSD during active sessions. If you are backtesting with forex-sized stops on gold, you are not testing a strategy — you are testing how fast gold eats tight stops.
The rule of thumb: multiply your forex stop by 2-4× when moving to XAUUSD. If you use 20-pip stops on EURUSD, start with 60-80 "pips" on XAUUSD. Then size your position down so the dollar risk stays the same.
Gold is a commodity with currency-pair naming. It correlates with USD strength (inversely), real yields, geopolitical risk, and equity market fear — factors that barely move EURUSD or GBPUSD. A technical setup that works on EURUSD during quiet Asian sessions may work on XAUUSD only during high-volatility US overlap. Your entry criteria need to be validated specifically on gold data, not assumed to transfer.
Forex pairs see their biggest moves during London open (8-9 AM GMT). Gold sees its biggest moves during the US session overlap with London (1-5 PM GMT), particularly around US economic data releases (CPI, NFP, FOMC). If you are backtesting XAUUSD with London-only session filters, you are missing gold's actual volatility window.
On forex, 1 standard lot = 100,000 units, and a 1-pip move = approximately $10 (varies by pair). On XAUUSD, 1 standard lot = 100 ounces, and a $1 move = $100 profit/loss. If you are used to EURUSD where a 50-pip move on 0.1 lots = $5, the equivalent on XAUUSD is a $5 move on 0.05 lots — but the price moves $30-50 in a day. Gold can move your account 5-10% in a single session if you are not sizing correctly.
Before backtesting XAUUSD: decide your dollar risk per trade first, then work backward to lot size. Never start with lot size and discover your risk later. This is true for all pairs but catastrophic to get wrong on gold.
