Margin on Gold: A Different Contract, a Different Requirement
Scenario: gold trades at 2,000 dollars per ounce. Your broker's contract is 100 ounces per lot, with leverage of 1 to 20 for gold. What does one lot require, and what does a sudden leverage change do?
Work it out. Notional value of one lot: 100 times 2,000 is 200,000 dollars. Required margin at 1 to 20: 10,000 dollars.
That is already large for a small account. A 0.10-lot position has a notional of 20,000 and margin of 1,000 dollars.
Now consider how fast gold moves. A 20-dollar daily move on one lot changes profit by 2,000 dollars. On 0.10 lots, 200 dollars. If your account has 3,000 dollars and you hold 0.10 lots, a 20-dollar move against you is 6.7 percent of equity.
If the broker changes leverage on gold from 1 to 20 to 1 to 5, as some do during volatile times, the same 0.10-lot position requires 4,000 dollars, more than your equity, and you would face an immediate margin shortfall.
This is why positions in volatile instruments should be sized with substantial free margin. Keep margin use well below your limit, so that increased requirements do not force liquidation.
Also remember that moves in gold are quoted in dollars, not pips, so adapt your risk calculations.
Takeaway: for volatile instruments, size smaller and keep a margin buffer.
Practical step: compute the margin and the loss from a 20-dollar adverse move for 0.10 lots of gold at the current price.
