For beginners entering financial trading, understanding the basic structure and logic of the forex market is the first step toward building a solid trading foundation. 

1. What Is Forex Trading? 

Forex trading simply refers to exchanging one currency for another. 

In the forex market, currencies are always traded in pairs, meaning when you buy one currency, you are simultaneously selling another. 

Examples of currency pairs: 

• EUR/USD (Euro vs US Dollar) – shows how many US dollars are needed to buy 1 euro. 
• GBP/JPY (British Pound vs Japanese Yen) – shows how many yen are needed to buy 1 pound. 

How traders profit: 
Traders aim to profit from changes in exchange rates. 

• If you believe a currency will increase in value, you buy. 
• If you expect it to decrease, you sell. 

By capturing price movements in the market, traders can potentially generate profits.
