Forex trading examples

Example 1
An investor has a margin deposit with Saxo Bank of USD 100,000.
The investor expects the US dollar to rise against the Swiss franc and therefore decides to buy USD 2,000,000 - 2% of his maximum possible exposure at a 1% margin Forex gearing.
The Saxo Bank dealer quotes him 1.5515-20. The investor buys USD at 1.5520.
Day 1: Buy USD 2,000,000 vs. CHF 1.5520 = Sell CHF 3,104,000.
Four days later, the dollar has actually risen to CHF 1.5745 and the investor decides to take his profit.
Upon his request, the Saxo Bank dealer quotes him 1.5745-50. The investor sells at 1.5745.
Day 5: Sell USD 2,000,000 vs. CHF 1.5745 = Buy CHF 3,149,000.
As the dollar side of the transaction involves a credit and a debit of USD 2,000,000, the investor's USD account will show no change. The CHF account will show a debit of CHF 3,104,000 and a credit of CHF 3,149,000. Due to the simplicity of the example and the short time horizon of the trade, we have disregarded the interest rate swap that would marginally alter the profit calculation.
This results in a profit of CHF 45,000 = approx. USD 28,600 = 28.6% profit on the deposit of USD 100,000.

Example 2:
The investor follows the cross rate between the EUR and the Japanese yen. He believes that this market is headed for a fall. As he is not quite confident of this trade, he uses less of the leverage available on his deposit. He chooses to ask the dealer for a quote in EUR 1,000,000. This requires a margin of EUR 1,000,000 x 5% = EUR 10,000 = approx. USD 52,500 (EUR /USD 1.05).
The dealer quotes 112.05-10. The investor sells EUR at 112.05.
Day 1: Sell EUR 1,000,000 vs. JPY 112.05 = Buy JPY 112,050,000.
He protects his position with a stop-loss order to buy back the EUR at 112.60. Two days later, this stop is triggered as the EUR o strengthens short term in spite of the investor's expectations.
Day 3: Buy EUR 1,000,000 vs. JPY 112.60 = Sell JPY 112,600,000.
The EUR side involves a credit and a debit of EUR 1,000,000. Therefore, the EUR account shows no change. The JPY account is credited JPY 112.05m and debited JPY 112.6m for a loss of JPY 0.55m. Due to the simplicity of the example and the short time horizon of the trade, we have disregarded the interest rate swap that would marginally alter the loss calculation.
This results in a loss of JPY 0.55m = approx. USD 5,300 (USD/JPY 105) = 5.3% loss on the original deposit of USD 100,000.
