Forex trading — short for foreign exchange trading — is the buying and selling of currencies on the global currency market with the aim of making a profit. With a daily trading volume exceeding $7.5 trillion, the forex market is the largest and most liquid financial market in the world — bigger than all global stock markets combined.
Unlike stock markets, forex has no central exchange. It operates as a decentralised, over-the-counter (OTC) market — a global network of banks, brokers, financial institutions, corporations, governments, and individual retail traders, all exchanging currencies around the clock.
In this guide — updated for 2026 — we cover everything a beginner needs to know: what forex is, how it works, who participates, what currency pairs are, how trading sessions work, what leverage and margin mean, the main trading strategies, and how to get started safely.
What Is the Forex Market?
The foreign exchange market (forex) is where currencies are traded. Every time a business converts revenue from one currency to another, a tourist exchanges money at an airport, or a central bank intervenes to stabilise its currency — a forex transaction takes place.
For retail traders, forex means speculating on whether one currency will rise or fall in value relative to another. If you believe the Euro will strengthen against the US Dollar, you buy EUR/USD. If the Euro rises as expected, you profit. If it falls, you lose.
The forex market serves several purposes in the global economy:
- Facilitating international trade: Companies that import or export goods must convert currencies to pay suppliers or receive payments.
- Hedging currency risk: Businesses and investors use forex to protect against adverse currency movements.
- Speculation: Traders attempt to profit from currency price movements.
- Central bank operations: Governments and central banks buy and sell currencies to manage exchange rates and monetary policy.
How Does Forex Trading Work?
Forex trading works by simultaneously buying one currency and selling another. Currencies are always traded in pairs — for example, EUR/USD (Euro vs US Dollar). The first currency in the pair is the base currency and the second is the quote currency.
If EUR/USD is quoted at 1.0850, it means one Euro buys 1.0850 US Dollars. If you believe the Euro will strengthen, you buy the pair (go long). If you believe it will weaken, you sell the pair (go short).
Bid, Ask, and Spread
Every forex quote has two prices:
- Bid price: The price at which the broker will buy the base currency from you (the price you sell at).
- Ask price: The price at which the broker will sell the base currency to you (the price you buy at).
- Spread: The difference between bid and ask. This is the broker’s primary source of revenue on standard accounts. Tighter spreads mean lower trading costs.
Pips
A pip (percentage in point) is the smallest standard price movement in a currency pair. For most pairs, one pip equals 0.0001 (the fourth decimal place). For example, if EUR/USD moves from 1.0850 to 1.0855, it has moved 5 pips.
Lots
Forex is traded in standardised contract sizes called lots:
| Lot Type | Units of Base Currency | Pip Value (approx. USD) |
|---|---|---|
| Standard Lot | 100,000 | ~$10 per pip |
| Mini Lot | 10,000 | ~$1 per pip |
| Micro Lot | 1,000 | ~$0.10 per pip |
| Nano Lot | 100 | ~$0.01 per pip |
Beginners should start with micro or nano lots to limit risk while learning the market.
Currency Pairs — Majors, Minors, and Exotics
There are hundreds of currency pairs available in forex, grouped into three categories:
Major Pairs
The most traded pairs globally, all involving the US Dollar. They offer the highest liquidity and tightest spreads:
- EUR/USD — Euro / US Dollar (most traded pair in the world)
- GBP/USD — British Pound / US Dollar
- USD/JPY — US Dollar / Japanese Yen
- USD/CHF — US Dollar / Swiss Franc
- AUD/USD — Australian Dollar / US Dollar
- USD/CAD — US Dollar / Canadian Dollar
Minor Pairs (Cross Pairs)
Pairs that do not include the US Dollar but involve major currencies. Examples: EUR/GBP, EUR/JPY, GBP/JPY. Slightly wider spreads than majors.
Exotic Pairs
One major currency paired with a currency from an emerging or developing economy. Examples: USD/TRY (Turkish Lira), USD/ZAR (South African Rand), USD/MXN (Mexican Peso). Higher spreads, higher volatility, and less liquidity — but potentially larger moves. Forex activity in emerging economies has grown significantly in recent years, as explored in our article on forex growth in Japan, Iran, and Mongolia.
Forex Trading Sessions — When Is the Market Open?
The forex market operates 24 hours a day, 5 days a week — from Sunday evening (22:00 GMT) to Friday evening (22:00 GMT). This is possible because trading is handed off between major financial centres as they open and close around the world.
| Session | Time (GMT) | Key Markets | Characteristics |
|---|---|---|---|
| Sydney | 22:00 – 07:00 | Australia, New Zealand | Low volatility, AUD/NZD pairs most active |
| Tokyo (Asian) | 00:00 – 09:00 | Japan, China, Singapore | JPY pairs most active, moderate volatility |
| London (European) | 08:00 – 17:00 | UK, EU, Switzerland | Highest volume — 35%+ of daily forex volume |
| New York (US) | 13:00 – 22:00 | USA, Canada | USD pairs most active, high volatility |
The most active and volatile period is the London-New York overlap (13:00–17:00 GMT) — when both the largest forex centres are simultaneously open. Most major price moves and economic data releases occur during this window.
Leverage and Margin in Forex
Leverage is one of forex’s most powerful — and most dangerous — features. It allows you to control a large position with a relatively small amount of capital.
For example, with 1:100 leverage, a $1,000 deposit controls a $100,000 position. A 1% move in your favour doubles your money. A 1% move against you wipes it out entirely.
| Leverage Ratio | Capital Required for $10,000 trade | 1% move profit | 1% move loss |
|---|---|---|---|
| 1:10 | $1,000 | +$100 (+10%) | -$100 (-10%) |
| 1:100 | $100 | +$100 (+100%) | -$100 (-100%) |
| 1:500 | $20 | +$100 (+500%) | -$100 (-500%) |
Margin is the deposit required to open a leveraged position. If a broker requires 1% margin on a $100,000 trade, you need $1,000 in your account to open it.
Who Participates in the Forex Market?
| Participant | Role | % of Volume |

| Hedge Funds | Speculative trading, large position sizes | ~15% |
| Corporations | Currency conversion for international trade, hedging | ~15% |
| Retail Traders | Individual speculation via broker platforms | ~5–8% |
| Brokers / ECNs | Provide market access and liquidity to retail traders | ~10% |
Main Forex Trading Strategies
Scalping
Opening and closing trades within seconds to minutes to capture very small price movements. Requires fast execution, tight spreads, and intense focus. Not suitable for beginners.
Day Trading
All positions are opened and closed within the same trading day — no overnight exposure. Reduces swap costs and weekend gap risk. Suitable for intermediate traders who can monitor markets during active sessions.
Swing Trading
Positions held for days to weeks, aiming to capture medium-term price swings. Less time-intensive than scalping or day trading. Most suitable for beginners and part-time traders.
Position Trading
Long-term trades held for weeks, months, or even years based on fundamental macroeconomic analysis. Low frequency, low stress, but requires deep understanding of economic drivers.
Carry Trade
Borrowing in a low-interest-rate currency and investing in a high-interest-rate currency to earn the interest rate differential (swap). Popular during stable market conditions but vulnerable to sudden reversals.
Essential Tools for Forex Traders
- Trading Platform: MetaTrader 4 (MT4) and MetaTrader 5 (MT5) are the industry standard. They offer charting, automated trading (Expert Advisors), and a wide range of technical indicators.
- Economic Calendar: Tracks scheduled economic data releases (NFP, CPI, central bank decisions) that drive major currency moves. Available free on most broker websites.
- Technical Indicators: RSI (Relative Strength Index), MACD, Bollinger Bands, Fibonacci retracement levels — tools for analysing price trends and identifying entry/exit points.
- Risk Management Tools: Stop-loss orders (automatically close a losing trade at a set level) and take-profit orders (close a winning trade at a target). Essential for every trader.
- Demo Account: A simulated trading account using virtual money. Every beginner should trade on demo for at least 2–3 months before risking real capital.
How to Get Started in Forex Trading — Step by Step
- Learn the basics: Study currency pairs, pip values, leverage, margin, and the main trading sessions before opening any account.
- Choose a regulated broker: Look for regulation by FCA (UK), ASIC (Australia), CySEC (EU), or equivalent. Check that the broker offers MT4/MT5, competitive spreads, and reliable customer support.
- Open a demo account: Practice with virtual money until you are consistently profitable over at least 2–3 months.
- Develop a trading plan: Define your strategy, risk per trade (typically 1–2% of account balance), daily loss limit, and profit targets before going live.
- Start small with a live account: Open a micro account with a small deposit. Focus on execution discipline, not profit, in the first months.
- Review and improve: Keep a trading journal recording every trade — entry reason, exit reason, result, and lesson learned. Review weekly.
Frequently Asked Questions
What is forex trading in simple terms?
Forex trading is buying one currency and simultaneously selling another, with the goal of profiting from changes in the exchange rate between them. For example, buying EUR/USD means you are buying Euros and selling US Dollars, betting the Euro will rise against the Dollar.
How much money do I need to start forex trading?
Many brokers allow you to open a live account with as little as $10–$50. However, trading with very small amounts limits position sizes and makes meaningful profit difficult. A more practical starting amount is $200–$500 using micro lots, which allows proper risk management with small position sizes.
Is forex trading profitable?
Forex trading can be profitable, but most retail traders lose money — studies suggest 70–80% of retail forex traders lose money over time. Profitability requires disciplined risk management, a proven strategy, and significant experience. It is not a get-rich-quick scheme.
What is the best time to trade forex?
The most active and liquid period is the London-New York overlap (13:00–17:00 GMT), when both the largest trading centres are open simultaneously. Most major economic data is released during this window, creating the largest price moves.
What is leverage in forex?
Leverage allows you to control a large position with a small deposit. With 1:100 leverage, $100 controls a $10,000 position. While leverage amplifies profits, it equally amplifies losses — a 1% adverse move on a 1:100 leveraged position wipes out the entire margin. Always use leverage cautiously.
What is the difference between forex and stocks?
Forex trades currency pairs 24/5 with no central exchange and very high liquidity. Stock trading involves shares of individual companies on regulated exchanges with set trading hours. Forex offers higher leverage and lower minimum deposits; stocks offer ownership in companies and dividends. Both involve significant risk.
