The following information is used for the next TWO questions.

Assume that you have sold two Australian dollar $($AUD$)$ futures contracts at the closing price on day $t=0.$ Over the subsequent days, the futures price has evolved as shown in the following table. All values are the closing futures price for that day.

$\backslash$table$[[$Day$,$Futures Price$],[t=0,$CHF$1\mathrm{.}0742/$AUD$],[t=1,$CHF$1\mathrm{.}0819/$AUD$],[t=2,$CHF$1\mathrm{.}0780/$AUD$],[t=3,$CHF$1\mathrm{.}0745/$AUD$],[t=4,$CHF$1\mathrm{.}0722/$AUD$]]$

Each futures contract on the Australian dollar has a size of AUD$125,000,$ an initial margin of $CHF2,000,$ and a maintenance margin of $CHF1,300.$ In addition, assume that you never withdraw any excess funds from your margin account and always meet any required margin calls.

Question $3$

What is the profit $(+)$ or loss $(-)$ on your position over the period $t=0$ to $t=4?$

Question $4$

What is the balance on your margin account at the end of day $t=4?$
