Forex trading refers to buying one currency while selling another. It takes place in the foreign exchange market, commonly known as forex or FX.
Currencies are used every day for international travel, trade, business payments and cross-border transactions. The forex market is where exchange rates between currencies are quoted and exchanged.
Unlike a traditional stock exchange, forex is generally an over-the-counter market. This means transactions can take place through banks, financial institutions, brokers and electronic trading systems rather than through one central exchange.
This article explains the basic structure of forex trading, how currency pairs are quoted, what can influence exchange rates and the key terms used in the market.
What Is the Forex Market?
The forex market is the global market for exchanging one currency for another.
An exchange rate shows the value of one currency in relation to another. For example, EUR/USD shows the value of the euro relative to the US dollar.
Forex activity takes place for many reasons. Banks may exchange currencies for client payments. Companies may need different currencies for international operations. Governments and central banks may manage foreign-currency reserves. Financial institutions may also participate in currency markets as part of their wider market activity.
For individual users, forex products may be available through authorised providers and online trading platforms. The products, order-execution arrangements, trading hours and conditions available can vary by provider, jurisdiction and account type.
How Forex Trading Works?
Forex is quoted and traded in currency pairs.
When a person places an order involving a currency pair, one currency is bought and the other is sold at the same time. The value of the position is linked to changes in the exchange rate between those two currencies.
For example, EUR/USD represents the euro against the US dollar. If the quoted rate changes, the relative value between the two currencies has changed.
A forex transaction may be opened through a market order, limit order or another order type made available by the platform. The way an order is handled depends on the product, provider, market conditions and execution policy.
The price shown when an order is submitted may not always be the final execution price. During fast-moving conditions, available prices can change quickly.
Understanding Currency Pairs
A currency pair contains two currency codes.
For example:
- EUR/USD — Euro and US dollar
- GBP/USD — British pound and US dollar
- USD/JPY — US dollar and Japanese yen
- AUD/USD — Australian dollar and US dollar
The first currency in the pair is called the base currency. The second is called the quote currency.
A currency pair quotation shows how much of the quote currency is needed for one unit of the base currency.
For example, if EUR/USD is quoted at 1.1000, this means one euro is quoted at 1.1000 US dollars.
Exchange rates move continuously while the relevant market is open. These movements can be influenced by economic data, central-bank decisions, political developments and changing market conditions.
Base Currency and Quote Currency
The two currencies in a pair have different roles.
Base Currency
The base currency is shown first in the pair.
In EUR/USD, the euro is the base currency.
Quote Currency
The quote currency is shown second in the pair.
In EUR/USD, the US dollar is the quote currency.
The quoted price shows the amount of the quote currency associated with one unit of the base currency.
Understanding this structure is important because it helps explain how a pair is priced and how movements in the exchange rate are displayed on a trading platform.
Buy and Sell Prices
Forex platforms commonly show two prices for a currency pair.
Bid Price
The bid price is the available price for selling the base currency.
Ask Price
The ask price is the available price for buying the base currency.
The difference between these two prices is known as the spread.
For example, if a platform displays a bid price of 1.1000 and an ask price of 1.1002 for EUR/USD, the spread is the difference between those prices.
Spreads can vary depending on the currency pair, market liquidity, time of day and market conditions.
What Can Influence Exchange Rates?
Currency exchange rates are influenced by many factors. No single factor determines how a currency pair will move.
Interest-Rate Decisions
Central-bank interest-rate decisions can influence currency markets. Market participants may also monitor policy statements, press conferences and economic outlooks issued by central banks.
Inflation Data
Inflation reports provide information about price changes within an economy. Currency markets may respond to inflation data alongside other economic indicators.
Employment and Economic Activity
Employment figures, gross domestic product data, retail-sales reports, manufacturing data and other economic releases may influence market conditions.
Political and Geopolitical Developments
Government policy, elections, trade developments and geopolitical events can affect market activity and exchange-rate movements.
International Trade
Imports, exports and cross-border business activity can influence demand for currencies. Trade data may therefore be monitored by market participants.
Market Sentiment
Market sentiment refers to the general view or level of caution among market participants. Sentiment can change quickly during major news events or periods of uncertainty.
Economic news can provide context, but it does not provide certainty about future market movements.
Major, Minor and Exotic Currency Pairs
Currency pairs are often grouped into broad categories.
Major Pairs
Major pairs usually include the US dollar and another widely traded currency.
Examples include:
- EUR/USD
- GBP/USD
- USD/JPY
- USD/CHF
- AUD/USD
- USD/CAD
- NZD/USD
Minor Pairs
Minor pairs generally involve widely traded currencies but do not include the US dollar.
Examples may include:
- EUR/GBP
- EUR/JPY
- GBP/JPY
- AUD/NZD
Exotic Pairs
Exotic pairs usually combine a widely traded currency with a currency from a smaller or developing market.
Available pairs, pricing and trading conditions can differ across platforms and jurisdictions. Some pairs may have wider spreads or lower liquidity during certain market conditions.
Forex Market Sessions
The forex market operates across major financial centres in different time zones during the business week.
The main sessions are commonly associated with:
- Sydney
- Tokyo
- London
- New York
As one major centre closes, another may be opening or already active. This creates overlapping periods when activity may increase.
However, specific trading hours can vary by provider, product and jurisdiction. Public holidays, daylight-saving changes, maintenance periods and exceptional market events can also affect availability.
Before placing an order, review the trading hours shown in the platform and the relevant product specification.
Common Forex Terms
Costs and Trading Conditions
Forex products can involve different charges and conditions. These can vary depending on the provider, jurisdiction, account type and product.
Common considerations may include:
- Spreads
- Commissions
- Financing charges where applicable
- Currency-conversion charges
- Margin requirements
- Platform fees where applicable
- Trading hours
- Order-execution arrangements
Market conditions can also affect pricing. During periods of reduced liquidity or significant news activity, spreads may widen and prices may move more quickly.
Before using a product, review the relevant product specification, fees, order-execution policy, client agreement and risk disclosures.
Margin and Leverage
Some forex products use margin and leverage.
Margin is the amount required to open or maintain a position. Leverage can increase the market exposure associated with a position.
Because leverage can increase the effect of price movements, it can also increase the level of risk. Margin requirements and available leverage can vary by product, provider, jurisdiction and market conditions.
It is important to understand how margin works, how requirements may change and what may happen if the value of an open position moves sharply.
🔖 Summary
Forex trading involves the exchange of one currency for another through currency pairs such as EUR/USD, GBP/USD and USD/JPY.
Exchange rates are influenced by a wide range of factors, including interest-rate decisions, inflation data, economic reports, political developments, international trade and market sentiment.
Understanding currency-pair structure, bid and ask prices, spreads, order types, costs, margin and leverage can help readers build a clearer foundation in forex-market terminology.
