Answer: No margin call
Explanation:
Based on the information given in the question, the new margin will be calculated as:
= Initial margin + (Sales - Settlement quote)/100 × Size
= 6100 + [(780 - 802)/100 × 5000]
= 6100 + (-22 × 5000)
= 6100 - 1100
= 5000
Since we've our new margin as 5000 while the maintenance margin is 4400, then there'll be no margin call once new margin is higher.
