Suppose that you sold a futures contract for $3.75 per bushel and the contract ended at

$3.60 after several days of closing prices of $3.80, $3.70, $3.65, $3.70, $3.65, and $3.60.

What would the mark to market sequence be?  

 

day 1 : -0.05

day 2 : +0.1

day 3 : +0.05

day 4 : -0.05

day 5 : +0.05

day 6 : +0.05

 What are the calculations ?
