How to Trade Gold (XAU/USD): A Step-by-Step Guide with Real Numbers
What one lot of gold is, the margin it takes, what a $1 move is worth, the overnight cost, and how to size a position so a bad day stays a small loss.

Quick answer: trading gold means buying or selling XAU/USD, the price of one troy ounce in US dollars, as a CFD. One lot is 100 ounces, so a $1 move is worth $100 per lot (or $1 on the minimum 0.01 lot). The margin is the position value divided by your leverage: at $4,140 an ounce and 1:100, 0.01 lot needs about $41. You can go long if you expect gold to rise or short if you expect it to fall.
This guide walks through every number you need before placing a first gold trade, using the live contract specifications from the GCC Brokers trading server.
Step 1: Know what you are trading
When you trade XAU/USD on MetaTrader 5 you are trading a contract for difference on the spot gold price. You do not take delivery of metal. Your profit or loss is the difference between the price when you open and the price when you close, multiplied by the size of the position.
The contract details at GCC Brokers (read live from the trading server, 4 October 2026):
| Specification | XAU/USD |
|---|---|
| Contract size | 100 troy ounces per lot |
| Price quoted to | 2 decimal places ($0.01) |
| Minimum trade | 0.01 lot (1 ounce) |
| Maximum trade | 50 lots |
| Lot step | 0.01 |
| Margin | Position value ÷ account leverage |
| Leverage | Up to 1:500, depending on account type and classification |
| Triple-swap day | Wednesday |
The XAU/USD page always shows the current figures, including the live spread.
Step 2: Work out the position value and margin
The position value is lots × 100 ounces × price. The margin you need to open it is that value divided by your leverage.
Take a gold price of $4,140.00:
| Trade size | Ounces | Position value | Margin at 1:100 | Margin at 1:500 |
|---|---|---|---|---|
| 0.01 lot | 1 | $4,140 | $41.40 | $8.28 |
| 0.10 lot | 10 | $41,400 | $414 | $82.80 |
| 1.00 lot | 100 | $414,000 | $4,140 | $828 |
Margin is a deposit, not a cost: it is returned when you close. But it is also not the amount you can lose. If the market moves against you, losses come out of the rest of your balance, and if your margin level falls to the stop-out level (20% on GCC Brokers accounts) positions are closed automatically.
The margin calculator does this for any size and leverage.
Step 3: Know what a move is worth
Because one lot is 100 ounces:
- A $1.00 move in gold = $100 per lot, $10 per 0.1 lot, $1 per 0.01 lot.
- A $0.01 move (one point, the smallest price step) = $1 per lot.
Gold often moves $20 to $40 in a normal day and much more around US data or geopolitical news. On one full lot, a $30 move is $3,000. On 0.01 lot it is $30. That difference is why position size matters more than anything else in this guide.
Step 4: Decide direction and set your exit before you enter
- Buy (long) if you expect gold to rise. You profit if the price goes up.
- Sell (short) if you expect it to fall. You profit if the price goes down.
Before opening, decide where you would accept being wrong (the stop-loss) and where you would take profit. A worked example:
Account balance: $5,000. You want to risk at most 1%, which is $50. You plan to buy at $4,140 with a stop-loss at $4,115, $25 below. Each 0.01 lot loses $25 if the stop is hit, so 0.02 lot risks $50. Margin at 1:100: about $83. Margin level stays far above stop-out.
Work it backwards every time: risk in dollars ÷ (stop distance × $1 per 0.01 lot) = number of 0.01 lots. The position size calculator does the arithmetic.
Step 5: Count the costs
Spread. The difference between the buy and sell price is paid when you open. It varies with market conditions and account type, and is usually widest around the daily pause and the Monday open. The Standard account has no commission; the Zero account trades on raw spreads with a commission.
Swap. A position open at the daily rollover (17:00 New York time, which is 01:00 in Dubai in summer) is charged or credited a swap. On 2 October 2026 the gold swap was -67.39 points per lot for a buy and +38.67 points for a sell. One point on one lot is $1, so holding one lot long for one night cost about $67, and 0.02 lot about $1.35. Wednesday night charges three nights, to cover the weekend. Rates are reset on the server daily; the swap calculator uses the current ones.
Step 6: Trade at the right hours
Gold trades almost 24 hours a day from Monday to Friday, with a one-hour pause each night. Liquidity is deepest when London and New York overlap, roughly 16:00 to 20:00 in Dubai on the summer schedule. Our guide to gold trading hours in Dubai and Riyadh time has the full timetable for both clock seasons.
What moves the gold price
- US interest rates and the Federal Reserve. Gold pays no interest, so higher expected rates tend to weigh on it and lower rates support it.
- Inflation data. CPI and PCE releases shift rate expectations within minutes.
- The US dollar. Gold is priced in dollars; a weaker dollar usually lifts it.
- Geopolitics and risk sentiment. Conflict and financial stress drive safe-haven demand.
- Central bank buying. Official purchases have been a large source of demand in recent years.
The economic calendar shows when the next market-moving releases are due, in your local time.
A checklist before your first gold trade
- Open a demo account and place the same trade there first.
- Decide your risk per trade in dollars, then size the position from your stop distance.
- Check the live spread on the XAU/USD page, and avoid the daily pause and Monday open.
- Know whether you will hold overnight, and on which night the triple swap falls.
- Keep your margin level well above the 20% stop-out.
