Why Gold Margin Is a Moving Target
When you trade gold, your broker sets margin as a percentage of the position's notional value. Notional value is the contract size multiplied by the gold price. Since the gold price changes constantly, the margin required to hold the same position changes with it. The fixed part is the contract specification: a standard lot is 100 troy ounces, a pip is a movement of $0.01, and that pip is worth $1.00 per standard lot. Lot sizes are written as 0.01, 0.10 or 1. The variable part is the gold price itself, which is why the live calculator above is the only place to get a current margin figure.
Leverage is simply the inverse of the margin percentage. If your account is on higher leverage, the margin percentage is lower, so less of your account equity is tied up as margin for the same notional exposure. Lower leverage means a higher margin percentage and more equity committed. Either way, the margin is not a static number you can memorise; it is recalculated as the gold price moves.

How Leverage Changes the Margin You Tie Up
Leverage and margin are two ways of describing the same relationship. The margin requirement is the fraction of notional value your broker holds aside. If leverage is higher, that fraction is smaller. If leverage is lower, the fraction is larger. For gold, the notional value of a standard lot is 100 troy ounces times the gold price, so the cash margin is that notional multiplied by the margin percentage. Because the gold price is always changing, the margin requirement for an open position will drift even if you do not change your lot size.
This matters for how much free margin you have available. Free margin is the equity left after margin is set aside. When the gold price moves against you, your equity falls and the margin requirement may rise if the notional value increases. Both effects can reduce your free margin. That is why gold traders watch their margin level closely, especially around volatile sessions like the London–New York overlap.

When Margin Level Triggers a Call
Margin level is your account equity divided by the margin currently required, expressed as a percentage. It is not a fixed number; it rises and falls with both your equity and the margin requirement. A margin call is triggered when that percentage falls to or below the broker's stop-out level. At that point, the broker may close positions to bring the margin level back above the threshold. Because gold's notional value moves with the price, a sharp adverse move can lower your equity and raise your margin requirement at the same time, pushing the margin level down faster than you might expect from the price move alone.
To manage this, you can reduce your lot size, add funds, or use lower leverage. Each action changes either the notional exposure or the margin percentage, which in turn changes the margin level. The live calculator above will show the current margin and margin level based on the latest gold price and your broker's leverage. Always check it before and during a trade, especially if you hold positions through the Asian, London or New York sessions.
Spreads are tightest when two sessions are open at once and widest when one desk has gone home and the next has not arrived. The shaded band is the overlap.
