Major currency pairs, also known as "majors," are the most commonly traded pairs in the Forex market. They typically involve the US Dollar (USD), the Euro (EUR), the British Pound (GBP), the Swiss Franc (CHF), the Japanese Yen (JPY), the Canadian Dollar (CAD), and the Australian Dollar (AUD). The USD/PLN pair, on the other hand, is classified as a "minor" pair. Minor pairs involve a major currency like the USD, but the other currency is from a developing economy and has a lower trading volume, such as the Polish Zloty (PLN).
