What Is Forex (FX)? – An Introduction to Forex Trading

There’s something enticing about using money to make money. This is exactly what happens in the foreign exchange (forex, or FX) trading, which involves exchanging one currency into another, with the aim of making a profit from changes in their relative value.

The forex market is the world’s largest financial market, with $7.5 trillion being traded on average each day, according to the latest survey of the Bank of International Settlements (BIS), dwarfing other markets, such as stocks, credit or commodities.

Forex trading has increased over the past three decades due to globalization and increased international trade. Retail investors began trading forex in the 1990s due to the growth of Electronic Communication Networks (ECNs), which made it possible for retail traders to access interbank markets.

Prior to that, speculation on the exchange rate between different currencies was confined to large financial institutions. The proliferation of online trading platforms then led to an exponential growth in retail forex trading. 

In this article, we’ll explain the mechanisms of the forex market and forex trading in detail, showing the different ways to trade forex, as well as the benefits and drawbacks of trading currencies for financial gain.

Understanding the forex market

Continue reading to find out how the forex market works, who the participants are, when and how you can access it, and how it’s regulated.

What is the forex market

The foreign exchange market (forex, FX market) is the marketplace for the buying and selling of currencies. It’s also the largest and most liquid financial market in the world. The size of the forex market may be hard to fathom as the daily trading volume is so vast ($7.5 trillion per day, to be precise, as we’ve written above.)

That’s six times larger than the combined trading volume of all the world’s stock markets, according to the BIS.

It’s important to note, however, that retail forex trading is responsible for only around 6% of the volume of currencies changing hands in the market.

Unlike stocks, which trade on exchanges such as the New York Stock Exchange or the London Stock Exchange, currencies trade through a decentralized global network of computers. Commercial and investment banks, corporations and other businesses, hedge funds, central banks, institutional investors, such as insurers and pension funds, as well as retail investors participate in the forex market.

They are exchanging currencies for a multitude of reasons, including practical purposes, such as to carry out international trade transactions, pay for contractors and suppliers overseas, and tourism.

However, the biggest part of currency transactions is conducted for financial reasons, such as hedging (offsetting potential losses in another market), and speculation (to earn profit from the shifts in currency values.)

The forex market has different layers depending on access:

The interbank market: This consists of primary dealers (market makers). These are the large banks, insurers and other institutions that trade large amounts of currencies.

The over-the-counter market: Individual traders who access the market via online brokerages and trading platforms.

The forex market also determines the value of each currency. The only meaningful way to express what a currency is worth is in relation to another currency. This is why currency trading always happens in pairs (forex pairs) by simultaneously buying and selling the two currencies linked in the pair.

Ultimately, currency values are determined in the interbank market, while other market participants use those exchange rates as the basis.

Similarly to many other markets, the forex market is very sensitive to geopolitical events. Events like elections, political instability, and international conflicts can cause dramatic currency swings.

Other factors that move currency markets include, supply and demand, economic data, such as a nation’s gross domestic product (GDP), inflation or unemployment figures, and perhaps most importantly central bank interest rate decisions.

The combination of the sheer size and liquidity of the global forex market and the high volatility of exchange rates caused by the factors outlined above create a lot of trading opportunities and make forex one of the most popular markets among speculators, including retail traders like you.

Where is the forex market?

Forex trading is a decentralized, or over-the-counter market and there’s no one location for forex trading. Currencies are traded through a global network of bank computers.

FX trading is concentrated in the biggest global financial centers: London, New York, Tokyo, and Sydney. London dominates the FX market with a 38% share in the daily turnover, according to the BIS.

Who trades on the forex market?

Retail traders are just one player in forex trading. The major players include governments and their central banks, commercial banks, financial institutions, corporations and retail traders.  A little of what each entity’s impact is on forex trading:

Central Banks: The banks that control each country’s money have a big impact on currency rates. Examples include: The Federal Reserve (US), European Central Bank (Europe), Bank of Japan (Japan), and Bank of England (UK). Central banks influence currency values by setting interest rates to attract foreign investment and by injecting money into an economy. They can also buy or sell currency to stabilize or change its value.

Commercial Banks: Major banks such as JPMorgan Chase, Deutsche Bank and HSBC facilitate large currency trades for their clients (multinational companies, big investors). They also trade on their own account (proprietary trading) to make profits. These large banks form the interbank market, the core of forex trading.

Financial Institutions: Hedge funds, investment firms, and pension funds also trade forex, to diversify their investments, protect against currency risks, and speculate on price changes. They do this with complex trading strategies involving large amounts of money.

Corporations: Businesses that import or export goods need to exchange currencies to pay for goods or receive payment. Like financial institutions, they may also use forex trading to hedge against fluctuations in the market.

Retail traders: These are individual investors who trade forex through online forex brokers. They trade to try and profit from currency price movements. They can also use  “leverage,” which allows them to trade larger amounts of money than they actually have, but it can also increase their losses.

When is the forex market open? 

Forex trading also owes its popularity among retail investors to the fact that because the FX market is open 24 hours a day, five days a week (weekdays).

Retail traders can access the forex market from Sunday at 5:00 pm ET to Friday at 5:00 pm ET.

This is because trading moves around the globe between the time zones of the four main trading centers (Sydney, Tokyo, London and New York). In other words, there’s always one main trading center that is open any time during the day, five days a week.

How is the foreign exchange market regulated? 

One drawback to forex is it’s prone to fraud, due to its globalized, speculative and decentralized nature. However, there are government agencies that regulate foreign exchange markets. 

Regulators such as the Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA)  in the US, the Financial Conduct Authority in the UK, the Financial Services Agency in Japan (FSA) and the Australian Securities and Investments Commission (ASIC) are important overseers of forex markets.

They do this through: 

Setting leverage limits: To protect investors from excessive risk, regulators often impose restrictions on the amount of leverage a broker can offer to retail traders. 

Conducting audits and inspections: Regulators carry out regular audits and inspections of forex brokers to ensure compliance with regulatory standards. 

Consumer protection: Regulators may provide mechanisms for handling complaints from traders against brokers and resolving disputes.

Licensing and supervision: Regulatory bodies issue licenses to forex brokers and other financial institutions and monitor activity to ensure compliance with the norms of transparency and best practices.

Standardization: Regulators issue standards and directives that investment service providers must follow. These can include capital requirements, negative balance protection, investor fund protection and others.

What is forex trading and how does it work? 

Forex trading is short for foreign currency trading or foreign exchange (FX) trading, and in its most simple form, it’s the conversion of one currency into another. People and businesses convert currencies for travel, trade, and investment. Forex trading, specifically, involves trying to profit from changes in the relative values of different currencies.

The various reasons people engage in forex trading

• Trade: International businesses need to exchange currencies to pay for goods and services from foreign suppliers. For example, a US company importing goods from Europe may need to convert US dollars into euros.
• Tourism: Travelers exchange their domestic currency for the local currency of their destination. This is a common and necessary exchange for international travel.
• Financial gain (speculation): Speculators aim to profit from fluctuations in exchange rates. They analyze market trends and economic data to predict future currency movements and place trades accordingly. For instance, if a trader believes the euro will strengthen against the US dollar, they will buy EUR/USD.
• Hedging: Businesses and investors use forex trading to hedge against currency risk. For example, a company with overseas investments may use forex contracts to protect against potential losses due to unfavorable exchange-rate movements. Hedging is a risk-management tactic to reduce the impact of adverse currency fluctuations on financial assets.

What does trading forex involve?

Trading currencies is not unlike buying or selling any other financial instrument. In the case of forex, the market price (exchange rate) tells a trader how much of one currency is required to purchase another.

For example, the current market price of the GBP/USD currency pair is 1.2897 (on March 11, 2025.) It shows how many US dollars it would take to buy one pound: £1 = $1.2897

Traders work with currency pairs, predicting whether one currency will rise or fall against another. If the bet is correct, they make money. If the market goes against them, they make a loss.

Currency values constantly fluctuate due to various economic and political factors, creating endless trading opportunities. Understanding these factors and their potential impact on currency values is essential for successful forex trading.

Forex trading involves a series of interconnected actions, starting with selecting a reputable forex broker who provides access to a trading platform. Traders then analyze currency pairs using technical and fundamental analysis to identify potential trading opportunities.

Technical analysis involves studying historical price charts and patterns to predict future price movements, while fundamental analysis focuses on economic indicators, news events, and geopolitical factors that can influence currency values. Once a trader identifies a trading opportunity, he or she places a buy or sell order through their trading platform, specifying the currency pair, trade size, and desired entry and exit points.

Ways to trade and invest in currencies

It’s important to understand the various ways to participate in the forex market, each with its own characteristics and risks. Here’s a breakdown:

Spot FX: This is the most common form of forex trading. It involves the exchange of one currency for another at the current market price. Trades settle “on the spot,” though in reality, settlement usually occurs within two business days. The spot market is highly liquid and operates 24 hours a day, making it accessible to a wide range of traders.

Forwards: Forex forwards are customized, private contracts between two parties to exchange currencies at a predetermined rate on a future date. Unlike spot trades, forwards are not standardized and are often used by corporations and institutions to hedge against future exchange rate fluctuations. This allows businesses to lock in a specific exchange rate for future transactions, reducing uncertainty.

Futures: Forex futures are standardized contracts traded on exchanges, obligating the buyer to purchase or the seller to sell a specific currency at a predetermined price on a future date. They are similar to forwards but trade on official exchanges, making them more transparent and liquid. Futures contracts have standardized sizes and settlement dates.

Options: Forex options give the buyer the right, but not the obligation, to buy or sell a currency at a specific price (the strike price) on or before a certain date. This provides flexibility, allowing traders to profit from favorable price movements while limiting potential losses. Options trading involves paying a premium to a broker for the right to exercise the option.

Currency ETFs: Currency ETFs (exchange-traded funds) are investment funds that track the value of a single currency or a basket of currencies. They trade on stock exchanges like regular stocks, providing a way to gain exposure to currency movements without directly trading forex. ETFs can be a simpler and more diversified option for some investors.

Forex CFDs (contracts for difference): CFDs allow traders to speculate on the price movements of currencies without actually owning them. A CFD is a contract between a trader and a broker, where they exchange the difference in price between the opening and closing of the trade. CFDs offer leverage and there are CFDs on spot forex, forex futures, and forex options. They are popular due to their flexibility and accessibility.

Spread betting: Spread betting is a form of speculation where traders bet on the direction of currency price movements. Profits and losses are determined by the accuracy of the prediction and the size of the price movement. Spread betting is popular in the UK and some other regions, and profits are often tax-free. However, it also involves high leverage, so losses can be significant.

The basics of forex trading for beginners

Forex trading involves buying and selling currencies with the goal of profiting from fluctuations in their exchange rates. Essentially, you’re speculating on whether one currency will increase or decrease in value relative to another. It’s the largest and most liquid financial market in the world, operating 24 hours a day, five days a week. Beginners should understand that it’s a high-risk, high-reward endeavor. Learning the basics of currency pairs, market analysis, and risk management is crucial before diving in. It makes sense to start with a demo account to practice without risking real money.

What are the base and quote currencies in a forex pair?

In a forex pair, like EUR/USD, the first currency (EUR) is the base currency, and the second currency (USD) is the quote currency. The base currency represents the unit of the purchase, and the quote currency shows how much of the quote currency you need to buy one unit of the base currency. So, if EUR/USD is 1.10, it means one euro is worth 1.10 US dollars. The base currency is always equal to one, and the quote currency is what changes in value.

What does it mean to buy or sell a currency pair?

When you “buy” a currency pair (go long), you’re speculating that the base currency will increase in value relative to the quote currency. If you “sell” a currency pair (go short), you’re betting that the base currency will decrease in value relative to the quote currency. For example, if you buy EUR/USD, you expect the euro to strengthen against the dollar. If you sell EUR/USD, you anticipate the euro to weaken against the dollar.

What is a forex broker?

A forex broker acts as an intermediary between you and the forex market. A broker provides trading platforms, access to currency pairs, and facilitates your buy and sell orders. Brokers often offer leverage, educational resources, and customer support. It’s important to choose a reputable and regulated broker to ensure the safety of your funds and a fair trading environment. They make money through the spread, or commissions.

While currency trading through electronic networks dates back to the 1970s, online forex trading platforms began to appear in the 1990s. The evolution of the internet and trading software made it possible for individuals to trade currencies on their computers. Online forex brokers make it easy to trade forex from anywhere.

What is a pip in a forex trade?

A pip (percentage in point) is the smallest price movement that a given exchange rate can make, and it’s the standard unit of measurement in forex trading. For most currency pairs, a pip is the fourth decimal place (0.0001). For example, if the EUR/USD moves from 1.1200 to 1.1201, that’s a one-pip increase. Profits or losses in a trade are calculated based on pips, too.

What is a lot in FX trading?

A lot is a standardized unit of measurement for the size of a forex trade. There are standard lots (100,000 units of the base currency), mini lots (10,000 units), micro lots (1,000 units), and nano lots (100 units). The lot size you choose directly affects the potential profit or loss of your trade. Larger lots result in greater potential gains or losses per pip movement.

What is the spread in forex trading?

The spread is the difference between the bid price (the price at which you can sell the base currency) and the ask price (the price at which you can buy the base currency). It’s essentially the broker’s commission. A narrower spread means lower trading costs. For example, if the EUR/USD bid price is 1.1200 and the ask price is 1.1202, the spread is 2 pips.

Margin and leverage in FX trading

Margin is the amount of money you are required to deposit into your trading account to open and maintain a leveraged position. Leverage allows you to control a larger position with a smaller amount of capital. For example, 100:1 leverage means you can control $100,000 worth of currency with $1,000 of your own money. While leverage can amplify profits, it also magnifies losses. It is important to use leverage with caution and implement strong risk- management strategies.

Popular forex trading strategies

All forex trading involves risk, but there are strategies investors can use to mitigate risk depending on the circumstances. Some popular forex trading strategies:

Scalping

Forex scalping is an extremely short-term trading strategy that aims to profit from small price changes. Scalpers often execute numerous trades throughout the day, sometimes holding positions for only seconds or minutes. They seek to accumulate small profits on each trade, which can add up to a substantial gain over time.

This strategy requires a high degree of focus, quick decision-making, and access to a fast and reliable trading platform. Due to the rapid nature of this strategy, it is very high risk.

Day trading

This method of trading  involves opening and closing positions within the same trading day. Day traders aim to capitalize on intraday price fluctuations, avoiding overnight risk. They typically use technical analysis to identify short-term trading opportunities. This strategy requires traders to be actively involved in the market throughout the day, monitoring price charts and responding to market movements.

Swing trading

This strategy involves holding positions for several days to weeks, aiming to capture price swings in the market. Swing traders use both technical and fundamental analysis to identify potential price movements. They seek to profit from medium-term trends and are less concerned with short-term fluctuations. This strategy allows for more flexibility than day trading, as traders don’t need to monitor the market constantly.

Trend trading

This method focuses on identifying and following the prevailing market trend. Trend traders aim to enter positions in the direction of the trend and hold them until the trend reverses. They use various technical indicators, such as moving averages and trend lines, to identify and confirm trends. This strategy can be applied to various timeframes, from short-term to long-term.

Position trading

This is a long-term strategy that involves holding positions for weeks, months, or even years. Position traders focus on long-term trends and fundamental analysis, such as economic data and geopolitical events. They are less concerned with short-term price fluctuations and aim to profit from significant market moves.

News trading

As the name implies, involves capitalizing on market volatility caused by economic news releases and other significant events. Traders who use this strategy must have a deep understanding of how news events can impact currency values.

They need to react quickly to news releases and execute trades accordingly. This strategy can be highly profitable but also carries significant risk, as news events can cause sudden and unpredictable market movements.

Pros and cons of trading forex

Forex demo accounts are a great way to understand the advantages and risks of forex trading. Forex trading’s global popularity stems from its numerous advantages. Key benefits include: unparalleled liquidity and volume, a 24-hour market, low transaction costs, the potential for amplified gains through leverage, and the flexibility to utilize diverse trading strategies.

However, forex can also be risky, particularly for unschooled investors. Trading with leverage can amplify an investor’s losses and forex trading is only simple on the surface, so new investors often face risks they are unprepared for.

The benefits of forex trading, explained

Liquidity and trading volume: The forex market is highly liquid, with over $6 trillion traded daily. This makes it the most liquid market in the world, allowing traders to enter and exit the market quickly.

The large trading volume provides price stability, minimizing the risk of slippage, and ensuring that forex traders can trade forex without delays.

Convenient 24-Hour market: One of the biggest advantages of forex trading is that the market operates 24 hours a day, five days a week. Forex market hours allow traders to trade at any time, accommodating different time zones and trading styles.

The forex market opens in the Asia-Pacific region and follows the sun across Europe and the Americas, creating a continuous trading cycle.

Low transaction costs: Forex trades typically have low transaction costs due to tight spreads offered by forex brokers. Most trading platforms have transparent fee structures, ensuring traders can minimize the costs of trading activities.

Unlike futures trading or the stock market, forex brokers do not charge commissions on trades but earn through the spread (the difference between the bid and ask prices).

Margin trading and leverage: Forex trading allows traders to trade with leverage, meaning they can control large positions with relatively small amounts of capital. Margin trading can amplify potential gains, making forex trading attractive for those seeking high returns.

Many online trading platforms offer flexible leverage ratios, depending on the trader’s experience and risk tolerance.

Diverse trading strategies: Forex traders can employ a wide range of trading strategies, from short-term day trading to long-term swing trading. This flexibility allows traders to tailor their approach according to their trading style and market conditions.

Traders in the forex market can also use automated trading systems and algorithms to enhance their trading decisions.

The main risks of forex trading, explained

High volatility and risk: The forex market is known for its high volatility, meaning currency prices can fluctuate rapidly and unpredictably. These fluctuations can be influenced by various factors, including economic news, geopolitical events, and market sentiment. This inherent volatility exposes traders to a substantial risk of significant losses, especially when leverage is used. The potential for quick profits is balanced by an equal potential for quick losses.

Leverage risks: While leverage can amplify gains, it also magnifies losses. This double-edged sword can lead to substantial financial setbacks if the market moves against a trader’s position. Even small price movements can result in significant losses that may exceed the initial investment. Therefore, without proper risk management, leverage can be extremely dangerous.

Complexity and lack of centralized regulation: The forex market is decentralized, meaning it operates without a central exchange. This lack of centralized regulation can create complexities and potential for counterparty risk. Additionally, understanding the numerous factors that influence currency prices requires a deep understanding of economics, geopolitics, and market analysis. This complexity can be overwhelming for novice traders.

The need for constant monitoring: Because the market is open 24 hours a day, it can be difficult to monitor all of the market changes. Because of this, traders can miss important price changes that can negatively affect their trading positions.
