What is Forex Trading?
Forex (Foreign Exchange) trading is the act of buying and selling currencies to profit from changes in exchange rates. Unlike stocks or commodities, forex trading involves simultaneous buying of one currency and selling of another, traded in pairs like EUR/USD or GBP/JPY.
Did You Know?
The forex market operates 24 hours a day, 5 days a week, allowing you to trade at any time that suits your schedule. This is because trading sessions overlap across different time zones globally.
The forex market exists because businesses, governments, and individuals need to exchange currencies for various reasons - from international trade to tourism. As a retail trader, you're speculating on these exchange rate movements to potentially generate profits.
The World's Largest Financial Market
The forex market is the largest and most liquid financial market in the world, with a daily trading turnover of about $9.6 trillion in April 2025, according to the Bank for International Settlements Triennial Survey. Most of that is interbank, corporate and institutional business — retail speculation is a small slice.
📊 Market Size Comparison
- Global FX turnover (BIS, April 2025): $9.6 trillion per day
- Most traded pair: EUR/USD
- Most traded currency: the US dollar, on one side of 89% of all trades
Deep liquidity in the major pairs usually means tight spreads — but liquidity thins around news releases, holidays and the daily rollover, when spreads widen and slippage increases.
Why Size Matters
- High Liquidity: Easy to buy and sell without affecting price
- Tight Spreads: Lower transaction costs on major pairs
- Many participants: Central banks, commercial banks, funds and companies all trade — although regulators fined several large banks in 2014–2015 for attempting to manipulate FX benchmark rates, so "too big to manipulate" is not true.

Understanding Currency Pairs
In forex, currencies are always traded in pairs. When you trade forex, you're essentially betting that one currency will strengthen or weaken against another.
Currency Pair Structure
EUR/USD = 1.1850
• EUR (Base Currency): The first currency in the pair
• USD (Quote Currency): The second currency in the pair
• 1.1850 (Exchange Rate): 1 EUR equals 1.1850 USD
Types of Currency Pairs
1. Major Pairs
Most traded pairs, all include USD:
- EUR/USD (Euro/US Dollar) - "Fiber"
- GBP/USD (British Pound/US Dollar) - "Cable"
- USD/JPY (US Dollar/Japanese Yen) - "Ninja"
- USD/CHF (US Dollar/Swiss Franc) - "Swissy"
- AUD/USD (Australian Dollar/US Dollar) - "Aussie"
- USD/CAD (US Dollar/Canadian Dollar) - "Loonie"
- NZD/USD (New Zealand Dollar/US Dollar) - "Kiwi"
2. Minor Pairs (Cross Currencies)
Don't include USD but involve other major currencies:
- EUR/GBP, EUR/JPY, GBP/JPY
- EUR/CHF, GBP/CHF, CHF/JPY
- EUR/AUD, GBP/AUD, AUD/JPY
3. Exotic Pairs
Include one major currency and one from a developing economy:
- USD/MXN (US Dollar/Mexican Peso)
- EUR/TRY (Euro/Turkish Lira)
- USD/ZAR (US Dollar/South African Rand)
⚠️ Beginner Warning
Start with major pairs only. They have tighter spreads, higher liquidity, and more predictable movements. Exotic pairs can be extremely volatile and expensive to trade.
How Forex Trading Works
The Basic Mechanics
Forex trading is straightforward in concept: you're trying to exchange one currency for another at an advantageous rate, then reverse the trade when the exchange rate moves in your favor.
📈 Real Trading Example
- Analysis: You believe EUR will strengthen against USD
- Entry: Buy EUR/USD at 1.1850 (buying EUR, selling USD)
- Movement: EUR/USD rises to 1.1950
- Exit: Close position (sell EUR, buy back USD)
- Profit: 100 pips × position size = your profit
Going Long vs. Going Short
📈 Going Long (Buying)
• Expect base currency to strengthen
• Buy the pair at a lower price
• Profit when price rises
• Loss when price falls
📉 Going Short (Selling)
• Expect base currency to weaken
• Sell the pair at a higher price
• Profit when price falls
• Loss when price rises
Leverage and Margin
Forex trading typically involves leverage, allowing you to control a large position with a relatively small amount of capital. While this can amplify profits, it equally amplifies losses.
🚨 Critical Risk Warning
Leverage is a double-edged sword. If you use the full 100:1 leverage, a 1% move against you wipes out the margin behind the position. What matters is your effective leverage (position size ÷ equity): keep it low, and size every trade from your stop-loss with the position size calculator. Retail limits are 30:1 on major pairs in the EU, UK and Australia and 50:1 in the US.
Essential Forex Terminology
Pip (Percentage in Point)
The smallest price move in a currency pair. For most pairs, it's the fourth decimal place (0.0001). For JPY pairs, it's the second decimal place (0.01).
Example: EUR/USD moves from 1.1850 to 1.1851 = 1 pip movement
Spread
The difference between the buy (ask) and sell (bid) price. This is essentially the broker's commission.
Example: Buy: 1.1852, Sell: 1.1850 = 2 pip spread
Lot Size
The unit of measurement for trading:
- Standard Lot: 100,000 units of base currency
- Mini Lot: 10,000 units
- Micro Lot: 1,000 units
- Nano Lot: 100 units
Margin
The amount of money required to open a leveraged position. Think of it as a security deposit.
Example: $1,000 margin at 100:1 leverage controls $100,000 position
