Currency Pairs if you say Forex


The Definition of Currency Pair
 

The quotation and pricing structure of the currencies traded in the forex market: the value of a currency is determined by its comparison to another currency.
The first currency of a currency pair is called the "base currency", and the second currency is called the "quote currency". The currency pair shows how much of the quote currency is needed to purchase one unit of the base currency.






currency pair is the quotation of the relative value of a currency unit against the unit of another currency in the foreign exchange market. The currency that is used as the reference is called the counter currency or quote currency and the currency that is quoted in relation is called the base currency or transaction currency.

2. NZD/USB: The pair changed its course from a steady and healthy rally to more range bound trading. 

3. EUR/AUD: While both EUR/USD and  AUD/USD are choppier and less predictable now, the cross is moving quite nicely. 

4. GBP/USDZ: Cable closed the list last time, and its behavior improved since then.

5. EUR/USD: The most popular pair closes the list.



Investopedia explains Currency Pair
All forex trades involve the simultaneous buying of one currency and selling of another, but the currency pair itself can be thought of as a single unit, an instrument that is bought or sold. If you buy a currency pair, you buy the base currency and sell the quote currency.
