A$.$ A foreign exchange trader with a U$.$S$.$ bank took a short position of $6,083,993$ when the $$/$ exchange rate was $1\mathrm{.}63.$ Subsequently, the exchange rate has changed to $1\mathrm{.}67.$ Compute the profit $($or loss$)$ of the short position.

B$.$ A bank is quoting the following exchange rates against the dollar for the Swiss franc and the Australian dollar:

SFr$/$$ $=$

A$$/$$ $=$

An Australian firm asks the bank for an A$$/$SFr quote. The cross$-$rate for an A$$/$SFr bid is $\_\_\_\_$ and for an A$$/$SFr ask is

C$.$ Assume you are a trader with Deutsche Bank. From the quote screen on your computer terminal, you notice that Dresdner Bank is quoting $0\mathrm{.}7627/$$$1\mathrm{.}00$ and Credit Suisse is offering SF$1\mathrm{.}1806/$$$1\mathrm{.}00.$ You learn that UBS is making a direct market between the Swiss franc and the euro, with a current $/$SF quote of $\mathrm{.}6395.$ Show how you can make a triangular arbitrage profit by trading at these prices. $($Ignore bid$-$ask spreads for this problem. Assume that you have $$5,000,000$ with which to conduct the arbitrage$)$

$($Please enter your answer in the format: e$.$g$.,$ buy $$50,000$ or sell $25,000)$

Step$1$: $($e$.$g$.,$ buy $$50,000$ or sell $25,000)$

Step$2$: $($e$.$g$.,$ buy $$50,000$ or sell $25,000)$

Step$3$: $($e$.$g$.,$ buy $$50,000$ or sell $25,000)$

Step$4$: total profit or loss is $($just the amount with currency sign, e$.$g$.,"$$$5,000"$ for a profit or $"-$$$5,000"$ for a loss

D$.$ If the exchange between Euro and U$.$S$.$ dollar is $$1\mathrm{.}285$ per euro, and the exchange rate between Switzerland franc $($SF$)$ and U$.$S dollar is $$1\mathrm{.}208$ per SF$.$ Compute the cross rate of euro$/$SF$($please keep for decimals, e$.$g$.,0\mathrm{.}0004).$

E$.$ If the exchange between Euro and U$.$S$.$ dollar is $$1\mathrm{.}353$ per euro, and the exchange rate between Switzerland franc $($SF$)$ and U$.$S dollar is $$1\mathrm{.}298$ per SF$.$ Compute the cross rate of SF$/$euro $($please keep for decimals, e$.$g$.,0\mathrm{.}0004).$
