Leverage is quoted as a ratio — 1:100, 1:500 — and it reads like permission to trade bigger. It is really a statement about how much of your balance the platform locks up as collateral, and therefore about how far the price can travel against you before the position is closed on your behalf. Those are two different facts, and confusing them is one of the more reliable ways to lose an account.
Buying gold on margin does not mean the platform hands you a suitcase of cash. It means you post a fraction of the trade's full value as collateral and the platform carries the rest. That fraction is the inverse of the leverage ratio: at 1:100 you post one percent of notional, at 1:500 you post 0.2 percent, at 1:20 you post five percent.
The full value is what matters for the arithmetic. A standard lot of XAU/USD is 100 troy ounces, so at 2,400 an ounce the notional value is 240,000. That number does not change when the leverage setting changes. Only the slice held as margin does.
| Term | What it means | Example: 10,000 deposit, 1 lot at 2,400, 1:100 |
|---|---|---|
| Balance | Cash from closed trades only | 10,000 |
| Equity | Balance plus the floating profit or loss | 9,800 if the position is 200 down |
| Used margin | Collateral locked by open positions | 2,400 |
| Free margin | Equity minus used margin; the room for new trades | 7,400 |
| Margin level | Equity divided by used margin, as a percentage | 408% |
Balance is history. Equity is the present. Liquidation is decided by equity, which is why a position can be closed while the balance still looks healthy — the loss has already happened, it simply has not been booked yet.
Margin is notional divided by the leverage ratio. At 2,400 an ounce, one lot is 240,000 of notional, so the collateral is straightforward:
| Leverage | Margin per standard lot | Maximum lots on 10,000 |
|---|---|---|
| 1:20 | 12,000 | 0.83 — less than one lot |
| 1:50 | 4,800 | 2.08 |
| 1:100 | 2,400 | 4.16 |
| 1:200 | 1,200 | 8.33 |
| 1:500 | 480 | 20.8 |
Read the right-hand column as a warning rather than an invitation. Nearly twenty-one lots on a ten-thousand account is not a strategy; it is a position that a two-dollar move can end.
Most platforms issue a margin call when margin level falls to around 100 percent and force-close positions at around 50 percent. Using that 50 percent figure, the buffer in dollars is:
Buffer = equity − (stop-out level × used margin)
10,000 equity, 2,400 used margin, 50 percent stop-out: 10,000 − 1,200 = 8,800 of room.
One lot moves 100 per dollar of gold, so 8,800 ÷ 100 = 88 dollars of adverse travel.
From 2,400 that is a fall to 2,312, a move of about 3.7 percent.
Now run the same trade at 1:500. The margin held drops to 480, the stop-out threshold to 240, and the buffer becomes 9,760 — a move of 97.60, closing at 2,312.40. Almost identical. This is the point that surprises people: for a fixed position size, changing the leverage setting barely moves the price at which you are liquidated. What changed was how much of the balance sat free, and therefore how much more could be piled on top.
One dollar of movement on one standard lot is worth 100 dollars, full stop. That figure is a property of the contract, not of the margin setting. A trader who risks fifty dollars by placing a stop eight dollars away is risking fifty dollars at 1:20 and at 1:500 alike.
What leverage changes is the ceiling on size, and size is the variable that decides everything else. Two traders can hold the same one-lot position and carry completely different risk, because one has ten thousand behind it and the other has two thousand. The honest measure is effective leverage: notional divided by equity. One lot on 10,000 equity is 24 times effective leverage, meaning a 4.2 percent move against the position erases the account. That number is visible before the trade and is far more useful than the ratio in the platform header.
If you want the mechanical relationship between ounces, lots and dollars per point, pips and lots for gold works through it. For choosing the size in the first place, position sizing from a fixed risk budget is the better starting point.
The danger appears when the whole balance is committed as margin, because then the buffer shrinks to nothing. If equity equals used margin, a stop-out at 50 percent triggers after a loss of half the balance, and the size was chosen so that the notional is leverage times the balance. The move required is therefore:
Distance to a 50 percent stop-out, fully margined = 0.5 ÷ leverage
1:20 → 2.5 percent, about 60 dollars at 2,400
1:100 → 0.5 percent, about 12 dollars
1:500 → 0.1 percent, about 2.40
Gold covers two dollars and forty cents in seconds around a US inflation print. At 1:500 with the account fully committed, the stop-out is not a risk management tool; it is a scheduled event. The lesson is not that high leverage is inherently reckless — it is that high leverage plus maximum size leaves no room for the market to breathe.
Not directly. A one dollar move on one standard lot of gold is worth one hundred dollars whether the account is set to 1:20 or 1:500. Leverage changes how much the platform holds as collateral and therefore how many lots you are allowed to open. It raises risk only through the position size it makes possible, which is why effective leverage — notional divided by equity — is the figure worth watching.
It is set by the platform, not by the leverage ratio, and fifty percent is a common level for a forced close with a warning around one hundred percent. Because it varies, the contract specification should be read before sizing a position. The stop-out price depends on equity, used margin and the stop-out percentage — not on how confident the trade feels.
Distance equals equity minus the stop-out percentage multiplied by used margin, divided by the value of a one dollar move. On one standard lot that value is one hundred dollars. With ten thousand of equity, twenty-four hundred of used margin and a fifty percent stop-out, the buffer is eight thousand eight hundred dollars — an eighty-eight dollar move, or about 3.7 percent at twenty-four hundred an ounce.
