Roger wants Robert to do more practice, so he asks him to do an example by himself. Below is the example that Robert needs to do: Three days ago, you entered into a futures contract to buy 62,500 at $1.30 per . You start with $3,000. Your maintenance margin is $1,000. 1. What is the critical rate where you will receive a margin call? 2. Over the past three days the contract has settled at $1.32, $1.28, and $1.26. How much have you made or lost in $ every day (day 1, 2, 3)? What is your balance at the end of each day? 3. What is your total profit or loss (in $) for the 3-day period? 4. Would you receive a margin call during this three-day period?
