You are long 30 gold futures contracts, established at an initial settle price of $1,542 per ounce, where each contract represents 100 troy ounces. Your initial margin to establish the position is $12,000 per contract and the maintenance margin is $11,200 per contract. Over the subsequent four trading days, gold settles at $1,531, $1,527, $1,537, and $1,547, respectively.
