i Short answer
XAU/USD is the price of one troy ounce of gold in US dollars. At most brokers one standard lot is 100 ounces, so a $1 move in the gold price is worth $100 per lot, which is about R1,655 at R16.55 to the dollar. A 0.01 lot moves R16.55 for every $1.
Gold CFDs trade almost 24 hours on weekdays, but the most liquid hours for South Africans are the London session from about 09:00 SAST and the London and New York overlap in the afternoon, when US data is released.
Key Takeaways
- One standard lot of XAU/USD is usually 100 ounces; check your broker’s contract size before trading.
- A $1 move is worth $100 per standard lot, $10 per mini lot and $1 per micro lot.
- Gold moves $20 to $60 on an ordinary day at current prices, so the rand risk per lot is large.
- Spreads are tightest during the London and New York sessions and widest around the daily rollover.
- The rand gold price also depends on USD/ZAR, which matters if your account is in rand.

1. What XAU/USD is
XAU is the international code for gold and USD for the US dollar, so XAU/USD is the dollar price of one troy ounce, quoted like a currency pair. Retail traders in South Africa almost always trade it as a CFD, tracking the spot price without owning or storing metal, as explained in how gold trading works in South Africa.
Gold has been unusually volatile in 2026, reaching a record above $5,500 in January before falling back to around $4,100 to $4,200 by October. At those levels a 1% daily move is $40 or more, which is why position size matters more on gold than on most currency pairs.
2. Lots, pips and rand value
At most brokers one standard lot of XAU/USD is 100 ounces, one mini lot is 10 ounces and one micro lot is 1 ounce. A $1 change in the gold price is therefore worth $100 on a standard lot, $10 on a mini lot and $1 on a micro lot. At R16.55 to the dollar that is R1,655, R165.50 and R16.55.
Brokers define a pip on gold differently: some use $0.01, some $0.10. That is why it is safer to think in dollars of price movement than in pips. If your stop is $15 away, a standard lot risks $1,500, about R24,800; to risk R1,000 you need about 0.04 lots. The index and gold position size calculator does this for any stop and account size.
3. Margin and leverage
Margin is the position value divided by leverage. One standard lot at $4,170 an ounce is worth $417,000, about R6.9 million. At 1:20, the EU and UK retail cap for gold, the margin is about R345,000; at 1:100 it is about R69,000; at 1:500 about R13,800.
South Africa has no statutory cap, so high leverage is common, as why brokers offer high leverage explains. On gold that is especially dangerous: a $40 move on one lot is R66,000, more than the margin at 1:100. The margin calculator shows the margin and the move that would trigger a margin call.
| Lot size | Ounces | Value of a $1 move |
|---|---|---|
| Standard (1.00) | 100 | $100, about R1,655 |
| Mini (0.10) | 10 | $10, about R165.50 |
| Micro (0.01) | 1 | $1, about R16.55 |
| 0.05 lots | 5 | $5, about R82.75 |
| 0.25 lots | 25 | $25, about R413.75 |
4. Best hours to trade gold in SAST
Gold CFDs trade almost continuously from Sunday night to Friday night, with a short daily break around midnight SAST. Liquidity is thin in the Asian morning, builds when London opens at about 09:00 or 10:00 SAST depending on UK clock changes, and peaks during the overlap with New York in the afternoon.
The biggest scheduled moves come with US data, released at 14:30 SAST while the US is on daylight saving time and 15:30 SAST in the US winter, and with Federal Reserve decisions in the evening. The session hours in SAST page has the current times.
5. What moves gold
Gold tends to rise when US real interest rates fall, when the dollar weakens, when central banks buy, and when geopolitical or financial stress increases demand for a safe asset. It tends to fall when real yields rise and the dollar strengthens. Big moves often come on US inflation and employment data.
For South Africans there is a second layer: the rand gold price is the dollar price times USD/ZAR. Gold priced in rand can rise even when the dollar price is flat if the rand weakens, which is part of the link between gold and the rand. The Krugerrand and gold value calculator converts any dollar price to rand per gram and per ounce.
6. Costs and tax
Gold spreads are usually around $0.10 to $0.40 during active hours and wider around the rollover and at the Sunday open. Positions held past the daily close pay overnight financing on the full position value, which is often negative on both long and short gold positions.
Profits are taxable in South Africa. Frequent short-term gold trading is usually treated as income at your marginal rate; the trading tax calculator gives the estimate.
- Contract size of one lot at your broker
- Rand value of a $1 move for your position size
- Stop distance in dollars, from the chart
- Position size from your rand risk per trade
- SAST time of the next US data release
- Overnight financing if you will hold past the close
★ Why It Matters
Gold attracts South African traders because it is familiar, liquid and tied to the rand. It is also one of the most volatile instruments a beginner can trade, and the default lot size is large.
The single most useful habit is to convert every gold trade into rand before placing it: stop distance in dollars, times the value per lot, times the exchange rate.
✕ Common mistakes
- Trading a full lot because it is the platform default.
- Thinking in pips when brokers define a gold pip differently.
- Ignoring the rand’s effect on a rand-denominated account.
- Holding gold CFDs for months and paying financing every night.
- Trading through US data releases with a tight stop.

Frequently asked follow-up questions
How much is one pip on gold?
It depends on how your broker defines a pip, either $0.01 or $0.10. It is clearer to use dollar movement: a $1 move is worth $100 on one standard lot of 100 ounces.
How much money do I need to trade gold?
With micro lots, a small account can open a position, but a normal daily move on 0.01 lots is several hundred rand. Size from your stop and risk, not from the minimum deposit.
What is the best time to trade XAU/USD in South Africa?
The London session from about 09:00 or 10:00 SAST and the London and New York overlap in the afternoon, especially around US data at 14:30 or 15:30 SAST.
Why does gold move so much?
It reacts strongly to US real interest rates, the dollar, central bank buying and geopolitical risk. At prices above $4,000 an ounce, a 1% move is $40.
Is trading gold better than buying Krugerrands?
They do different jobs. CFDs are for short-term trading with leverage and financing costs; Krugerrands are owned outright, carry no VAT and suit long-term holding.
Do I pay tax on gold trading profits?
Yes. Frequent gold CFD trading is usually taxed as income at your marginal rate.
