Currency Pair in Forex is a quotation of two different currencies. The first currency in the pair is the base currency or transaction currency. The second currency in the pair is marked quote currency, payment currency or counter currency. This quote shows how many units of the counter currency needed to buy a unit of the base currency.

For example, the listing EUR / USD 1.2500 means that one euro is 1.25 against the U.S. dollar. If the offer moves from EUR / USD 1.2500 EUR / USD 1.2510, the euro is getting stronger and the weaker dollar. On the other hand, if the EUR / USD moving quote from 1.2500 to 1.2490 to the euro is getting weaker, while the dollar is getting stronger.

All forex trading involves the simultaneous purchase of one currency and the sale of another, but the currency pair itself can be viewed as a unit, a tool that is bought or sold. If you buy a pair currency, you buy the base currency and sell the quote currency. The offer (buy) represents how much of the variable currency is necessary for you to get a unit of the base currency. Conversely, if you sell the currency pair, you sell the base currency and variable currency. The letters page (sale price) for the currency pair represents how much you receive in the variable currency for the sale of a unit of the base currency.
