Pip Value & Contract Specifications
Gold (XAU/USD) has a contract size of 100 troy ounces per standard lot. One pip = $0.01 (one cent of gold price movement). This gives a fixed pip value of $1.00 per standard lot, regardless of the current gold price — unlike forex pairs where pip value shifts with the exchange rate. In IDR terms the value changes daily with the USD/IDR rate.
| Lot Size | Contract (oz) | Pip value (USD) | Pip value (IDR @ 18.50) | 500-pip stop loss |
|---|---|---|---|---|
| 0.01 (micro) | 1 | $0.01 | R0.185 | ~R92.50 |
| 0.10 (mini) | 10 | $0.10 | R1.85 | ~R925 |
| 0.50 | 50 | $0.50 | R9.25 | ~R4,625 |
| 1.00 (standard) | 100 | $1.00 | R18.50 | ~R9,250 |

Position Sizing Example
Suppose you have a R50,000 account and risk 1% per trade (R500). You place a 500-pip stop loss on XAU/USD (a normal intra-day buffer given gold's volatility).
At USD/IDR 18.50, each pip per lot = R18.50. The formula:
Lots = Risk ÷ (Stop pips × Pip value dalam IDR)
Lots = R500 ÷ (500 × R18.50) = R500 ÷ R9,250 ≈ 0.054 lots
Round down to 0.05 lots (5 micro-lots). This keeps your risk within budget even if gold gaps through your stop on a major news event.
About XAU/USD — Key Drivers & Trading Hours
Gold is one of the most volatile instruments available to retail traders. A typical daily range is 500–1,000 pips (using the $0.01 pip convention), and on high-impact days (Fed decisions, geopolitical shocks) moves can exceed 3,000 pips. Indonesia traders have a natural affinity for gold — Indonesia is historically one of the world's largest gold producers, and the IDR maintains a well-documented negative correlation with gold prices.
The key drivers of XAU/USD price are: US Dollar strength (inverse relationship), real interest rates and Fed policy expectations, safe-haven demand during geopolitical crises, and central bank gold reserve purchases. The COMEX gold futures market sets the global price benchmark.
Best trading hours for XAU/USD in SAST: London–New York overlap 14:00–18:00 SAST offers the tightest spreads and highest liquidity. The COMEX open around 16:30 SAST is frequently the most volatile 30-minute window of the day. Avoid market orders before 09:00 SAST when spreads can widen to 30+ pips.
Warning: Gold's 500–1,000 pip daily ATR means even a modest 0.10 lot position can swing R925–R1,850 in a single session. Start with micro lots (0.01–0.03) until you have a calibrated sense of how gold moves on your chosen time frame.
