You have purchased one futures contract on the Canadian dollar at a price of $0\mathrm{.}9082$ at the close of business today $($day $1).$ The initial and maintenance margins are $$1600$ and $$1200$ per contract, respectively. The notional amount $=C$$$100,000$ and one tick $=$ $$\frac{0\mathrm{.}0001}{C}S.$

Over the course of the next $5$ days, the closing prices are:

$\backslash$table$[[$Day$,$Close$],[1($today$),0\mathrm{.}9082],[2,0\mathrm{.}9062],[3,0\mathrm{.}9045],[4,0\mathrm{.}9057],[5,0\mathrm{.}9063],[6,0\mathrm{.}9085]]$

What is your account balance each day? What is your total profit$/$loss$?$

$3.$ Suppose that you shorted five futures contracts on the euro, receiving a price of $1\mathrm{.}2166($day $1).$ Your broker requires initial margins of $$\frac{1500}{?}$ contract and maintenance margins of $$\frac{1100}{?}$ contract. Recall that the contract size on sterling futures is $125,000.$ Suppose the closing prices over the next few days are:

$\backslash$table$[[$Day$,$Price$],[1,1\mathrm{.}2166],[2,1\mathrm{.}2188],[3,1\mathrm{.}2182],[4,1\mathrm{.}2202],[5,1\mathrm{.}2175],[6,1\mathrm{.}2163]]$

What is your account balance each day? What is your total profit$/$loss$?$
