Quoting Conventions

In the Foreign Exchange market, currencies are traded in pairs. For instance, a speculator may trade the Euro versus the US Dollar, EUR/USD, or the US Dollar versus the Japanese Yen, USD/JPY. The base currency is the term for the first currency in the pair. The counter currency is the term for the second currency in the pair. The exchange rate represents the number of units of the counter currency that one unit of the base currency can purchase.

Traders in the Foreign Exchange market are speculating on the exchange rate between two currencies. Exchange rates measure the relative strength of one currency to another. Speculators make buy and sell decisions on currency pairs based on fundamental and technical analysis, with the intention of the exchange rate moving in their favor.

EUR/USD
In this example euro is the base currency and thus the “basis” for the buy/sell.

If you believe that the US economy will continue to weaken and this will hurt the US dollar, you would execute a BUY EUR/USD order. By doing so you have bought euros in the expectation that they will appreciate versus the US dollar. If you believe that the US economy is strong and the euro will weaken against the US dollar you would execute a SELL EUR/USD order. By doing so you have sold euros in the expectation that they will depreciate versus the US dollar.

 

If you think the British economy will continue to be the leading economy among the G7 nations in terms of growth, thus buying the pound, you would execute a BUY GBP/USD order. By doing so you have bought pounds in the expectation that they will appreciate versus the US dollar. If you believe the British are going to adopt the euro and this will weaken pounds as they devalue their currency in anticipation of the merge, you would execute a SELL GBP/USD order. By doing so you have sold pounds in the expectation that they will depreciate against the US dollar.

USD/CHF
In this example the USD is the base currency and thus the “basis” for the buy/sell.

If you think the Swiss franc is overvalued, you would execute a BUY USD/CHF order. By doing so you have bought US dollars in the expectation that they will appreciate versus the Swiss Franc. If you believe that due to instability in the Middle East and in U.S. financial markets the dollar will continue to weaken, you would execute a SELL USD/CHF order. By doing so you have sold US dollars in the expectation that they will depreciate against the Swiss franc.

Sample Trade

A trader wishes to speculate on EUR/USD. Believing that the EUR will rise against the USD, or that the exchange rate will move upwards, the trader places an order to buy EUR/USD at a market rate of 1.3050. Let us also assume that the trader is speculating on 100,000 units of the base currency, which is the standard lot size, or trading increment, used in the Foreign Exchange market. Since the base currency is the first currency in the pair, the trader is speculating on the value of 100,000 Euros with respect to the US Dollar.

In this example, the trader is buying Euros, since he believes the Euro will rise in value with respect to the US Dollar. Accordingly, he finances the transaction of buying 100,000 Euros by borrowing an equivalent amount of US Dollars.

For the trader, the value of the amount borrowed is a function of the exchange rate. Since the exchange rate at the time of the transaction was 1.3050, the market cost for 1 Euro was 1.3050 US Dollars. Hence, 100,000 Euros cost $130,500 (1.3050 * 100,000). This borrowed amount of 130,500 USD must be paid back when the transaction is closed.

Let’s assume that the trader is correct in assuming that the Euro would rise in value with respect to the USD, and that the exchange rate moved to 1.3150, 100 pips above the rate at which the trader entered. If the trader were to close his position now, the 100,000 Euros he purchased at the onset of the transaction would be sold, and his debt of 130,500 US Dollars would be paid off.
