Answer:
$0.20
Explanation:
For computing the change in future price, first we have to determine the loss which is shown below:
Loss = Initial Margin - Maintenance Margin
= $4,000 - $3,000
= $1,000
Now the change in future price would be
= Loss ÷ size of the contract
= $1,000 ÷ 5,000 ounces
= $0.20
The future price is increased by $0.20
And, if the margin call is not meet than the broker will stop at best price so that he cannot suffer more loss
