Gold is one of the most traded instruments in the world, but almost every generic trading journal gets the math wrong. The result: your P&L looks right but your R calculations are off, your risk-per-trade is miscalculated, and your performance data is lying to you.
The XAUUSD Contract Size Problem
XAUUSD has a contract size of 100 troy ounces per standard lot. This means:
- 1 standard lot (1.0) = 100 oz = $100 per $1 price move
- 1 mini lot (0.1) = 10 oz = $10 per $1 price move
- 1 micro lot (0.01) = 1 oz = $1 per $1 price move
The correct P&L formula is: price_distance × contract_size × lots
So if you sold 0.01 lots at 2324.83 and exited at 2329.50, your loss is:
(2329.50 - 2324.83) × 100 × 0.01 = 4.67 × 1 = $4.67
Many journals use a pip value of $10 or divide by pip size incorrectly, giving you a P&L that's off by a factor of 10. Always verify against your MT5 statement.
How to Import XAUUSD Trades from MT5
In MetaTrader 5:
- Go to View → Terminal → Account History
- Right-click → Save as Detailed Report (this saves as HTML)
- Import the HTML file into your trading journal
A good journal will automatically detect XAUUSD and apply the correct 100 oz/lot contract size, and calculate your commission separately (typically $5 per standard lot on ECN accounts).
Setting Up R Calculations for Gold
Your stop loss distance on XAUUSD is usually measured in dollars, not pips. If you enter at 2320 with a stop at 2315, your stop is $5 away. On 0.1 lots, your dollar risk is $5 × 100 × 0.1 = $50.
This means your R multiples are based on dollar risk, not pip risk. Always log:
- Entry price — where you entered
- Stop loss price — your actual stop, not your mental stop
- Lot size — exact size taken
From these three values, your journal can calculate exact dollar risk and realized R for every trade.
Common XAUUSD Journaling Mistakes
1. Not logging the session. Gold has very different behaviour in the London session vs NY Open. Asian session gold is often choppy and range-bound. Logging session lets you discover where you actually make money.
2. Not tracking news days. NFP, CPI, and Fed announcements cause extreme XAUUSD moves. If you trade these, flag them. If you don't, make sure your journal shows you're avoiding them.
3. Ignoring spread on small accounts. On micro lots, a 30-pip spread on gold can eat 30% of a typical trade's profit. Log commission separately to see your true edge.
The best gold traders I've seen all share one habit: they review their last 20 trades before taking the next one. The journal is the edge.
