The foreign exchange market—commonly called forex or FX—is where one currency is exchanged for another. At its simplest, forex is the system that sets the price of one country’s money relative to another’s. Those prices, called exchange rates, change continuously as buyers and sellers trade currencies around the world. For everyday people it looks familiar: converting dollars to euros before a trip. For traders it becomes a market where people try to profit from changes in those exchange rates. Trading carries risk; this article is educational and not personal financial advice.
How the forex market works
Forex trading always involves a pair of currencies. One currency is the base and the other is the quote. When you see EUR/USD quoted at 1.10, that means one euro is worth 1.10 US dollars. If you buy that pair you are buying euros and selling dollars; if you sell the pair you are selling euros and buying dollars. These paired prices move as supply and demand change.
Most trading is electronic and over-the-counter rather than on a single exchange. That means banks, brokers and other participants connect by computer systems and trade continuously during business days. Because trading shifts from one financial center to another, the market is effectively open 24 hours a day from Monday morning in Asia until Friday evening in New York. That continuous flow is why forex is the world’s most liquid market—large trades can often be executed quickly without big price jumps.
Who trades currencies and why
A wide range of participants use the forex market for different reasons. Large commercial banks and institutional investors provide much of the market’s liquidity. Corporations use forex to pay suppliers and manage the risk of doing business in other currencies. Central banks intervene at times to stabilise or influence their national currency. Hedge funds and professional traders speculate on expected moves. Retail traders—individuals using online brokers—now make up a visible, though smaller, share of daily turnover.
Each group approaches the market with a different goal. A manufacturer importing parts wants to settle a legitimate payment; a hedge fund may take a leveraged bet on an interest-rate-driven move; a tourist swaps cash for local currency. Those different motives create the continuous buying and selling that drive exchange rates.
Main instruments and ways to trade
Currencies can be traded in several forms. The spot market is the simplest: currencies are exchanged “on the spot” at the current price, or with settlement a couple of days later. Forward contracts let two parties agree today on a price for a future exchange; companies use them to lock in costs. Futures and options are exchange-traded versions of forward-like commitments and rights, which standardise size and settlement. Retail traders commonly trade derivatives such as contracts for difference (CFDs) or margin spot contracts offered by brokers—these let traders gain exposure without physically moving currencies.
For example, a US exporter expecting to be paid in euros in three months might sell euros forward now to avoid the risk that the euro falls in value before payment. A retail trader, by contrast, might buy EUR/USD through a broker because they expect the euro to strengthen against the dollar over the next few days.
Key trading terms explained simply
Prices in forex move in small units called pips. For most pairs a pip is the fourth decimal place; if EUR/USD moves from 1.1000 to 1.1001, that’s one pip. Traders usually work with standardised trade sizes called lots. A standard lot equals 100,000 units of the base currency; mini and micro lots are smaller, and many brokers let retail traders use these to control position size.
Leverage is a central feature of forex trading: it lets you control a large position with a relatively small deposit (margin). For example, 50:1 leverage means a $1,000 deposit can control $50,000 of currency. While leverage can magnify gains, it also magnifies losses and can lead to losing more than your initial deposit if the market moves quickly against you.
Spreads are another important concept: the broker’s buy and sell prices differ slightly, and that difference is a trading cost. During periods of low liquidity or after major news, spreads can widen and execution can be poorer.
What moves exchange rates?
Exchange rates respond to whatever changes the balance of supply and demand for a currency. Several types of events routinely move the market. Central bank interest-rate decisions or statements can powerfully shift expectations about returns available in a currency. Economic data—like inflation, GDP, and employment—can change investors’ views on a country’s prospects and its currency. Geopolitical events, elections, or sudden crises can trigger rapid “flight-to-quality” moves into safe-haven currencies. Market sentiment and traders’ positioning also matter: if many traders are crowded into one side, a small trigger can cause big price swings.
An example: if the central bank of a country unexpectedly raises interest rates, foreign investors may buy that country’s bonds to benefit from higher yields. That demand for local bonds usually increases demand for the local currency, causing it to appreciate against others.
How retail traders approach the market
Retail traders generally access forex through regulated brokers that provide trading platforms, charts and order types. Most start on demo accounts to learn execution and test strategies without risking real money. Typical strategies include trend-following, which seeks to ride a developing directional move; range trading, aiming to buy at support and sell at resistance when prices are oscillating; and news trading, which attempts to capitalise on market reactions to scheduled releases.
Order types such as market, limit and stop-loss orders help manage entries and exits. A stop-loss is especially important: it sets a predefined point at which a losing trade will be closed to limit damage. Position sizing—deciding how much of your account to risk on each trade—is another cornerstone of responsible trading.
Practical example: a simple trade story
Imagine you expect the euro to strengthen against the dollar after strong European GDP data. You open a small buy position on EUR/USD, buying 0.1 standard lot through your broker. The pair moves up 50 pips and you close the trade. Your profit equals 50 pips times the pip value for your trade size, minus spreads and any overnight financing if you held the position beyond the trading day. Had the trade moved the other way and hit your stop-loss set at 30 pips, you would have limited your loss to that pre-agreed amount. The trade’s outcome depends on position size, leverage, and how well risk was controlled.
Risks and caveats
Trading forex carries significant risks and is not suitable for everyone. Leverage can amplify losses and lead to rapid account depletion; volatile news events or thin-market conditions can produce slippage where your order fills at a worse price than expected. Counterparty risk—relying on a broker or dealer to honour trades—matters, so choosing a reputable, regulated broker is important. Weekend gaps can leave positions exposed to moves while the retail market is closed. Algorithmic or high-frequency players can affect short-term price action in ways that are hard for individual traders to predict. Emotional factors—overtrading, revenge trading after losses, or ignoring a trading plan—are common causes of failure.

Steps to get started carefully
Begin with a clear learning path: study basic terms, practice on a demo account, and track your progress in a trading journal. Choose a broker that is regulated in your jurisdiction, offers transparent pricing and reliable execution, and provides risk management tools. Build a simple trading plan that defines when you will enter, where you will place a stop-loss, and how you will size each position relative to your account balance. Start small, protect capital with sensible stops, and treat learning as the main objective—profits, if they come, will follow disciplined learning and risk control.
