Forex trading is the buying and selling of currencies from different countries, done through banks, brokers, and trading platforms rather than a central exchange

When you trade forex, you are betting that one currency will gain or lose value against another. For example, you might buy euros while selling US dollars, betting that the euro will strengthen. The trade happens in pairs — always one currency against another — and the price moves constantly based on supply, demand, interest rates, and economic news. Unlike stock markets, forex trading runs 24 hours a day across Tokyo, London, and New York, so there is always a market open somewhere.

Most forex trading happens between large banks, hedge funds, and professional traders. Retail traders — people trading their own money — make up a smaller portion but can open accounts through brokers that let them trade with borrowed money, called leverage. This means you can control a large position with a small deposit, which amplifies both gains and losses.

Key Takeaways

  • Forex trades happen in currency pairs, with one currency bought and another sold simultaneously, 24 hours a day across global markets.
  • Prices move based on economic data, interest rate decisions, geopolitical events, and the flow of money between countries.
  • Retail traders typically use brokers and leverage to trade, meaning they control large positions with small deposits and face proportionally large losses.
  • The bid-ask spread — the difference between what you pay to buy and what you receive to sell — is how brokers make money and affects your cost per trade.
  • Forex trading is not regulated the same way as stock trading, and brokers operate under different rules depending on their country and your location.

How currency pairs and pricing work

Every forex trade involves two currencies written as a pair, like EUR/USD (euro and US dollar). The first currency is the base currency and the second is the quote currency. When you see EUR/USD at 1.0950, that means one euro costs 1.0950 US dollars. If the price rises to 1.0960, the euro has strengthened — you would need more dollars to buy one euro.

The price you see on your screen is actually two prices at once: the bid (what buyers will pay right now) and the ask (what sellers want right now). The difference between them is the spread. If EUR/USD shows a bid of 1.0948 and an ask of 1.0950, the spread is 0.0002. You buy at the ask (1.0950) and sell at the bid (1.0948), so you lose the spread immediately. Tighter spreads mean lower costs; wider spreads mean higher costs. Spreads vary by currency pair, broker, and market conditions.

Prices move in small increments called pips. For most currency pairs, one pip is 0.0001 — the fourth decimal place. If EUR/USD moves from 1.0950 to 1.0951, that is a one-pip move. Traders measure profit and loss in pips because the actual dollar amount depends on how much you are trading.

What moves forex prices

Currency values shift based on which country's economy looks stronger and where investors think money will earn better returns. If the US Federal Reserve raises interest rates, investors want to hold more dollars to earn that higher rate, so demand for dollars increases and the dollar strengthens. If the European economy enters recession, investors sell euros, and the euro weakens.

Economic data releases — jobs reports, inflation figures, GDP growth — cause sharp price moves because traders immediately recalculate what a currency should be worth. Central bank decisions and statements move markets even more. Geopolitical events like elections, wars, or trade disputes also shift currency values when they change the outlook for an economy.

Supply and demand from real-world transactions matter too. When a US company buys goods from Europe, it needs euros, so it sells dollars to buy them. Multiply that across millions of transactions and you see currency flows that push prices. Tourism, investment flows, and government spending all affect which currencies people need.

Leverage and how it changes the stakes

Retail brokers offer leverage, typically 50:1 or 100:1, meaning you can control $100,000 in currency with $1,000 of your own money. This amplifies returns — a 1% move in your favor becomes a 50% or 100% gain on your deposit. But it also amplifies losses. A 1% move against you wipes out your entire $1,000 deposit or more.

Leverage is why forex trading is risky for retail traders. You can lose more than you deposited. If your account drops below a certain level (the margin requirement), the broker automatically closes your positions to stop further losses. This is called a margin call. You have no choice — the broker closes the trade whether you want it closed or not.

Different brokers set different leverage limits, and the rules vary by country. In the United States, retail brokers can offer up to 50:1 leverage. In Europe, the limit is lower. Some countries ban retail leverage entirely or require warnings about the risk of losing money.

How brokers make money and what you pay

Forex brokers do not charge commissions the way stock brokers do. Instead, they make money from the spread — the difference between bid and ask prices. Every time you open a trade, you pay the spread. On a tight spread like 1 pip, the cost is small. On a wide spread, especially during volatile market hours or for exotic currency pairs, the cost is larger.

Some brokers also charge a small fee per trade or offer accounts with tighter spreads but a per-trade commission. A few brokers make money by taking the other side of your trade — betting against you. These are called market makers. Others, called ECN brokers, route your trade to the market and charge a commission instead of widening the spread. The model matters because it affects your costs and whether the broker has an incentive for you to lose.

Overnight holding costs also apply. If you keep a position open past the end of the trading day, the broker charges or credits you interest based on the difference in interest rates between the two currencies. This is called the rollover or swap. On some pairs, especially when you are short a high-interest currency, the cost can be significant.

Regulation and where brokers operate

Forex brokers are not regulated the same way as stock brokers or banks. In the United States, the Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) oversee retail forex brokers, but the rules are lighter than for stock trading. In Europe, brokers must be regulated by their country's financial authority, and there are stronger protections for retail traders. In other countries, regulation ranges from strict to nonexistent.

This matters because an unregulated or lightly regulated broker can disappear with your money, offer unfair pricing, or refuse to pay out winnings. Before opening an account, check whether the broker is regulated and by whom. A broker regulated by the CFTC, the UK Financial Conduct Authority, or the European Securities and Markets Authority offers more protection than one registered in a jurisdiction with no real oversight.

Brokers also vary in how they handle your money. Some hold client funds in segregated accounts, meaning your money is separate from the broker's operating money and protected if the broker fails. Others do not. This is a basic question to ask before depositing.

Spot forex versus futures and forwards

Spot forex is the most common type of retail trading. You buy or sell a currency pair at the current market price, and the trade settles in two business days. This is what most retail brokers offer.

Forex futures are standardized contracts traded on regulated exchanges like the Chicago Mercantile Exchange. They have fixed sizes, expiration dates, and are regulated like stock futures. Futures are more transparent than spot forex because prices are public and the exchange guarantees the trade, but they are less flexible and have higher minimum positions.

Forwards are custom contracts between two parties, usually banks or large institutions, to exchange currencies at a set price on a future date. They are not traded on an exchange and are not regulated for retail traders. Most retail traders never encounter forwards.

Frequently Asked Questions

Can I make money trading forex?

Yes, but most retail traders lose money. The combination of leverage, spreads, and the difficulty of predicting currency moves means that statistically, the majority of retail accounts end up negative. Successful forex traders typically have years of experience, strict risk management, and realistic expectations about returns.

What is the minimum amount I need to start?

Brokers vary, but many allow you to open an account with $100 to $500. However, starting with a small deposit and using high leverage is a common way to lose that money quickly. Most professionals recommend starting with an amount you can afford to lose entirely and using low leverage while you learn.

Is forex trading the same as currency exchange at an airport?

No. Airport currency exchange is a one-time transaction at a fixed rate. Forex trading is speculative — you are betting on price movements and using leverage. The spreads at an airport are also much wider than in forex markets because you are paying for the convenience of the exchange service.

What time of day should I trade?

The most active and liquid hours are when two major markets overlap — typically London and New York overlap in the morning US time. During these hours, spreads are tighter and prices move more predictably. Trading during low-volume hours (late US evening or early Asian morning) often means wider spreads and more erratic price moves.

Do I need to watch the market all day?

No. You can set stop-loss and take-profit orders that close your position automatically at a certain price, so you do not have to monitor the screen constantly. However, major news events or gaps in price overnight can cause your stop-loss to execute at a worse price than you expected, especially if the market moves very fast.
