How the Forex Market Works

Currency Trading Mechanism

In the Forex market, you don't buy a single currency — you always trade currency pairs. When you buy one currency, you simultaneously sell another.

EUR/USD transaction example:

• Buy EUR/USD = buy euros, sell dollars
• Sell EUR/USD = sell euros, buy dollars
• Rate 1.0850 = for 1 euro you get 1.0850 dollars

1. EUR/USD — euro/US dollar (23% of turnover)
2. USD/JPY — dollar/Japanese yen (14% of turnover)
3. GBP/USD — British pound/dollar (9% of turnover)
4. USD/CHF — dollar/Swiss franc (5% of turnover)
5. AUD/USD — Australian dollar/US dollar (5% of turnover)
6. USD/CAD — dollar/Canadian dollar (4% of turnover)
7. NZD/USD — New Zealand dollar/US dollar (2% of turnover)

Key Concepts in Forex

Spread

Spread is the difference between the buy price (Ask) and sell price (Bid).

EUR/USD example:

• Bid: 1.0845 (sell price)
• Ask: 1.0847 (buy price)
• Spread: 2 pips (0.0002)

Pip

Pip (percentage in point) is the smallest unit of currency rate change.

• For most pairs: 4th decimal place (0.0001)
• For yen pairs: 2nd decimal place (0.01)
• Example: EUR/USD rose from 1.0845 to 1.0855 = 10 pips increase

Leverage

Leverage allows trading larger amounts than available capital.

Popular leverage ratios:

• 1:30 (for retail investors in EU)
• 1:100 (for professional investors)
• 1:500 (brokers outside EU)

Example with 1:30 leverage:

• Deposit: 1000 EUR
• Maximum position: 30,000 EUR
• Control: position worth 30x more than capital
