Suppose that you enter into a short futures contract to sell July silver for 55.20 per ounce on the New York Commodity Exchange. The sire of the contract is 5.000 ounces. The initial margin is 54.000, and the maintenance margin is 53,000. What change in the futures price will lead to a margin call? What happens if you do not meet the margin call?
