what are forex trading markets

Currency/Forex/FX markets
The foreign exchange markets trade one state or
economic bloc’s currency versus another’s (commonly
called a cross rate). These markets are traded in ‘pairs’
of two separate currencies (i.e GBP/EUR is the Sterling
versus Euro currency pair). When a ‘Buy’ trade is made
in a currency pair the client is anticipating that the fist
quoted currency is going to rally versus the second.
Therefore if a client ‘Buys’ the EUR/YEN cross he wants
the Euro to rally versus the Yen.
