What Is Forex Trading? How the Currency Market Works
Forex trading is the buying and selling of global currencies on the foreign exchange market, where participants exchange one currency for another at agreed-upon prices to profit from fluctuations in exchange rates. It operates 24 hours a day across decentralised electronic networks, making it the world's largest and most liquid financial market with daily trading volumes exceeding $7.5 trillion, according to the Bank for International Settlements.
How Does Forex Trading Work in Practice?
Forex trading works through currency pairs—you simultaneously buy one currency and sell another. When you trade EUR/USD at 1.0850, you're buying euros and selling US dollars, expecting the euro to strengthen against the dollar.
Every currency pair shows a bid price (what buyers will pay) and an ask price (what sellers want). The difference—the spread—represents the broker's commission.
What Are the Main Currency Pairs Traders Use?
Major currency pairs account for roughly 75% of forex trading volume and include EUR/USD, USD/JPY, GBP/USD and USD/CHF. These pairs all involve the US dollar and offer the deepest liquidity, narrowest spreads and most predictable price movements.
Traders choose pairs based on trading hours, volatility preferences and fundamental factors. The London-New York overlap (8 a.m. to noon Eastern) sees the heaviest volume and tightest spreads for EUR/USD and GBP/USD.
How Much Money Do You Need to Start Forex Trading?
Retail forex brokers typically allow account minimums from $0 to $500, though practical starting capital depends on your risk tolerance and strategy. With a $500 account and conservative 1% risk per trade, you'd risk $5 on each position—enough for micro lots (1,000 units) on major pairs but limiting your strategic options.
Leverage magnifies both the opportunity and the danger for small accounts. A beginner using 10:1 leverage on a $1,000 account controls $10,000 in currency, but a 2% adverse move costs $200—a fifth of the account.

What Moves Forex Prices and Exchange Rates?
Interest rate differentials drive long-term currency trends because capital flows toward higher yields. When the Federal Reserve raises rates while the European Central Bank holds steady, investors sell euros to buy dollar-denominated bonds, strengthening USD/EUR.
Economic indicators release on fixed schedules and trigger immediate volatility. US Nonfarm Payrolls (first Friday of each month), GDP reports, Consumer Price Index data and Purchasing Managers' Index figures all move major pairs.
Is Forex Trading Risky for Beginners?
Forex trading carries substantial risk, particularly for beginners who underestimate leverage and overestimate their ability to predict short-term price movements. The combination of 24-hour markets, high leverage and rapid price swings means accounts can suffer significant losses in hours.
Regulatory protections vary by broker jurisdiction. US-registered brokers must maintain membership in the NFA and comply with CFTC capital requirements, segregating customer funds from company assets.
What Are the Tax Rules for Forex Trading Profits?
The Internal Revenue Service (IRS) treats forex gains and losses differently depending on whether you trade spot forex contracts or exchange-traded currency futures. Spot forex (the majority of retail trading) defaults to Section 988 treatment as "ordinary gain or loss," taxed at your regular income rate up to 37%.
Forex traders must report every closed position on IRS Form 8949 and Schedule D if claiming capital gains treatment, or on Form 4797 and Schedule C if trading as a business. The IRS allows deductions for platform fees, data subscriptions, education and home-office expenses if you qualify as a trader (the Tax Court defines this as frequent, regular trades attempting to profit from short-term swings, not occasional investing).
FAQ
Can you make a living from forex trading?
Some full-time traders earn consistent income from forex, but it requires substantial capital (often $50,000+), years of experience, disciplined risk management and the psychological resilience to handle losing streaks. Most professionals risk 0.5-1% per trade and target 2-5% monthly returns, not the 10-20% gains advertised by unlicensed promoters.
How do forex brokers make money if trading is commission-free?
Forex brokers earn primarily through the bid-ask spread—the difference between buy and sell prices. On a EUR/USD spread of 1.2 pips, the broker captures $12 per standard lot traded.
What is a pip in forex trading?
A pip (percentage in point) measures the smallest price increment in a currency pair, typically the fourth decimal place (0.0001) for most pairs or the second decimal (0.01) for yen pairs. If EUR/USD moves from 1.0850 to 1.0855, that's a 5-pip change worth $5 per mini lot or $50 per standard lot.
Do I need a special license to trade forex?
Retail forex traders do not need a license—you're trading your own capital, not managing others' money. However, anyone offering forex trading advice for compensation, managing client accounts or operating a fund must register with the CFTC and NFA as a Commodity Trading Advisor (CTA) or Commodity Pool Operator (CPO), meeting strict capital and reporting requirements.
How is forex different from stock trading?
Forex trades currency pairs 24 hours a day with no central exchange, while stocks trade on exchanges (NYSE, Nasdaq) during set hours. Forex offers higher leverage (up to 50:1 in the US versus 2:1 for stocks), lower capital requirements and no uptick rule for short selling.
What are the best times to trade forex?
The highest liquidity and tightest spreads occur during session overlaps: London-New York (8 a.m.–noon ET) for EUR/USD and GBP/USD, and Tokyo-London (3–4 a.m. ET) for yen pairs.

How the interest calculator estimates compound growth
Compound interest applies each period’s rate to the starting balance plus previously credited interest. This interest computation differs from simple interest, which calculates interest only on the original principal. A daily compound interest calculator uses more compounding periods than a monthly or annual model, although the practical difference depends on the stated rate, account terms, and length of time.
Enter a starting amount, recurring contribution, assumed return, compounding frequency, and time horizon. The resulting future value calculator estimate is not a guarantee, particularly when modeling an investment with changing returns. For deposit accounts such as high yield savings, compare the annual percentage yield rather than relying only on the stated interest rate. The rule of 72 can provide a rough mental estimate, but a calculator offers more detail.
