Why “pip” means different things on gold
Gold is quoted as XAUUSD: the number of US dollars for one ounce. On currency pairs such as EUR/USD the market broadly agrees that a pip is 0.0001, but gold has no single definition: some brokers count a pip as 0.1 dollars, others as 0.01 dollars, usually following how many decimals the platform shows.
That is why one trader says gold moved “100 pips” and another says “10 pips” about the same move, which is one dollar on the ounce price. Both are right by their own definition. The clearest habit is to measure moves in dollars per ounce, then convert to pips using your broker’s definition.
Illustrative exampleIf the price goes from 4000.00 to 4001.00, the move is one dollar per ounce. If your broker’s pip is 0.1, that is 10 pips; if it is 0.01, it is 100 pips.
Contract size: where the 100 comes from
One gold lot stands for a set number of ounces that your broker states in the symbol’s specification. The common size is 100 ounces per lot, the same as the standard COMEX gold futures contract at CME Group. Some brokers use a different size, so do not assume 100 before you check.
In MetaTrader you find it in Market Watch: right-click XAUUSD, choose Specification and look for Contract size.
The gold pip value formula
Pip value = contract size × pip size × number of lots.
Because gold is quoted in dollars, the result is in dollars. With a 100-ounce contract:
- Standard lot (1.00): a 0.01 move is 1 dollar, a 0.1 move is 10 dollars, and a one-dollar move is 100 dollars.
- Mini lot (0.10): a 0.1 move is 1 dollar, and a one-dollar move is 10 dollars.
- Micro lot (0.01): a 0.1 move is 0.10 dollars, and a one-dollar move is 1 dollar.
Notice that the steadiest number is what a one-dollar move is worth: one standard lot on a 100-ounce contract makes or loses 100 dollars for every dollar the ounce price moves, whatever the pip definition.
Example: what you make or lose when gold moves
Example with made-up numbers, for illustrationYou buy 0.30 lots at 4000.00 with a broker whose contract is 100 ounces, and close at 4006.00. The move is 6 dollars per ounce and your size is 0.30 × 100 = 30 ounces, so the profit is 6 × 30 = 180 dollars. Had you closed at 3996.00, the loss would be 4 × 30 = 120 dollars.
The same sum in pips: with a 0.1 pip the move is 60 pips, the pip value for your size is 100 × 0.1 × 0.30 = 3 dollars, and the profit is 60 × 3 = 180 dollars. Same answer, because both methods measure the same thing.
Lot size on gold from your risk
The safer way is to start from the amount you accept to lose if the stop-loss is hit, and derive the size from it:
Lot size = risk amount ÷ (stop distance in dollars per ounce × contract size).
Example with made-up numbers, for illustrationYour balance is 10,000 dollars and you risk 1%, so 100 dollars. Entry is 4000.00 and the stop is 3995.00, a distance of 5 dollars per ounce. Lot size = 100 ÷ (5 × 100) = 0.20 lots. Check: 0.20 lots = 20 ounces, and 20 × 5 = 100 dollars, exactly the amount you set.
If the result is a size the platform does not accept (say 0.237), round it down to the nearest allowed size (0.23) so the loss never exceeds the amount you set.
If your account is not in dollars
The formulas above give dollars because gold is quoted in dollars. If your account is in euros or another currency, convert the result at the current exchange rate between the dollar and your account currency. That is why the pip value in such accounts shifts slightly as the exchange rate moves, even with the same trade size.
Common mistakes with gold pips
- Carrying the currency-pair rule (0.0001) over to gold, which makes the pip value completely wrong.
- Assuming every broker uses a 100-ounce contract without checking the symbol specification.
- Mixing up 0.1 and 0.01 when reading “pips” in a post or a signal, so the stop looks ten times closer or further than it is.
- Sizing from a pip count without knowing your broker’s pip definition; measuring the distance in dollars per ounce is safer.
- Forgetting the spread: on gold it is measured the same way and is part of the trade’s cost, so it belongs in your target and stop.
Skip the manual sums with Joymista
Joymista has two tools that apply all of this for you. FOREX CALCULATOR starts with your broker and fills in the contract size, then gives you the pip value and the trade’s profit or loss in dollars. POSITION CALCULATOR starts from your balance, your risk and your entry and stop, and gives you the distance in pips and the suggested lot size. Both count a gold pip as 0.1 dollars with a 100-ounce contract by default.
