XAU/USD Gold Position Size Calculator
Gold (XAU/USD) has unique specifications compared to regular forex pairs. One standard lot = 100 troy ounces. One pip = $0.01 per ounce = $1.00 per standard lot. This is significantly different from EUR/USD where 1 pip = $10/lot.
Getting position size wrong on gold is one of the most common mistakes traders make, especially those transitioning from forex. Gold's daily range of 100–300+ pips means an oversized position can wipe your FTMO daily limit in a single candle.
Frequently Asked Questions
What is the pip value for XAU/USD gold?
For XAU/USD: 1 pip = $0.01 per ounce. Since 1 standard lot = 100 oz, the pip value = $0.01 × 100 = $1.00 per pip per standard lot. This is much lower than EUR/USD ($10/pip/lot). For a mini lot (0.1), pip value = $0.10. For a micro lot (0.01), pip value = $0.01.
Why does gold need a larger SL than forex pairs?
Gold's average daily range (ATR) is typically 100–300 pips, compared to EUR/USD at 70–120 pips. Setting a 20-pip SL on gold means you will be stopped out frequently by normal price noise. A typical ATR-based SL for gold is 150–250 pips (1.0–1.5× ATR), which in dollar terms is only $1.50–$2.50 per mini lot — still very manageable with proper position sizing.
How does ATR-based position sizing work for gold?
ATR (Average True Range) measures volatility. Setting SL at 1.5× ATR means your stop is 1.5 standard deviations of recent volatility away, reducing the chance of being stopped by noise. For gold ATR(14) of 150 pips: SL = 1.5 × 150 = 225 pips = $2.25 per mini lot. With $10,000 account and 1% risk ($100), safe lots = $100 ÷ (225 × $1) = 0.44 lots.
What lot size is safe for gold on FTMO $10,000?
For FTMO $10,000 with 1% risk per trade: Risk amount = $100. With typical gold SL of 100 pips: Safe lots = $100 ÷ (100 × $1) = 1.0 lot. With 200-pip SL: 0.50 lots. Always keep your daily total risk well under 5% ($500) as FTMO's daily loss limit applies to the entire day's P&L including floating losses.
What R:R ratio should I use for gold trading?
Most professional gold traders use minimum 1:1.5 or 1:2 R:R. With gold's high volatility, targets of 150–400 pips are common when SL is 100–200 pips. A 1:2 ratio means you only need to be right 34% of the time to break even. For EA/algorithmic trading, backtesting should confirm that the average winner is at least 1.5× the average loser.
