Problem:
You buy eight contracts of Euro currency futures (i.e. total of one million Euros) with an initial margin of $2835 per contract. You buy the contracts at $1.3468/Euro and after a few days of trading the contracts end at a price of $1.3534/Euro with the following ending price each day: $1.3465, $1.3443, $1.3434 and $1.3534. What would be the margin account value per day? [Starting value being $22,680 (i.e. 8*2835 = $22,680)].
