Example 1
An investor has a margin deposit with GO Markets of USD 100,000.
The investor expects the US dollar to rise against the Japanese Yen and therefore decides to buy USD 3,000,000.
On GO Markets, he is quoted USD/JPY 119.40-44, and he buys UDS/JPY at 119.44. Buy USD 3,000,000 x JPY 119.44 = Sell JPY 358,320,000
Four days later, the dollar has risen to JPY 120.50 and the investor decides to take his profit. The spread on GO Markets is 120.50-54. He sells at 120.50. Sell USD 3,000,000 x JPY 120.50 = Buy JPY 361,500,000
Profit / Loss calculation
As the dollar side of the transaction involves a credit and a debit of USD 3,000,000 the investor's USD account will show no change.
The JPY account will show a debit of JPY 358,320,000 and a credit of JPY 361,500,000 for a profit of JPY 3,180,000, equal to approximately USD 26,390 for a 26.4% profit on the deposit of USD 100,000.
Example 2
An investor analyzing the cross rate between the Euro and Swiss Franc believes the market is headed for a fall.
As he is moderate in his risk taking, he does not fully utilise the leverage available on his deposit, seeking instead to sell EUR 1,000,000 x 2% = EUR 20,000 = approximately USD 22,627.00 at the prevailing spot rate, thereby using approximately 22% of his available margin.
On GO Markets, he is quoted 1.5426/31. He sells EUR 1,000,000 v. CHF 1.5426 = buy CHF 1,542,600.
He protects his position with a stop-loss order to buy back the Euro at 1.5460. Two days later, this stop is triggered as the Euro strengthens short term despite the investor's original expectations. Buy EUR 1,000,000 v CHF 1.5460 = Sell CHF 1,546,000.
Profit / Loss calculation
The EUR side involves a credit and debit of EUR 1,000,000 thus the EUR account shows no change.
The CHF account is credited CHF 1,542,600 and debited CHF 1,546,000 for a loss of CHF 3,400 = approximately USD 2,500, a 2.5% loss on the original deposit of USD 100,000.
Due to the simplicity of the example and the short time horizion of the trade, we have disregarded the interest rate swap that would marginally alter the loss calculation.
Example 3
The investor believes the Canadian dollar will strengthen against the US Dollar. It is a long-term view, so he takes a small position to allow for wider swings in the rate.
On GO Markets, he sees a quote in USD 1,000,000 against the Canadian dollar of 1.3840 / 45. The investor sells USD/CAD at 1.3840. Selling USD is the equivalent of buying Canadian dollars. He swaps the position out for two months and receives a forward rate of 1.3880 for day 61 due to the interest rate differential between the two currencies.
After one month, the desired move has occurred. The investor buys back US dollar at 1.3615. He has to swap the position forward for a month to match the original sale. The forward rate is agreed at 1.3635. Buy USD 1,000,000 v. CAD 1.3635 = sell CAD 1,363,500 for day 61.
The two trades are settled and the trades go off the books. Profit secured on Day 31 can be used for margin purposes before Day 61.
Profit / Loss calculation
The USD account receives a credit and debit of USD 1,000,000 and shows no change on the account.
The CAD account is credited CAD 1,388,000 and debited CAD 1,363,500 for a profit of CAD 24,500 (approximately USD 18,000) = profit of 18% on the original deposit of USD 100,000.
