What is Forex Trading? Tips and Pointers

If you have exchanged money before an overseas trip, you have encountered an exchange rate. But what is forex trading, and how does it differ from buying holiday money?

Forex trading, also called foreign exchange or FX trading, involves buying one currency while selling another. Speculative traders aim to profit from changes in exchange rates, rather than simply obtaining foreign currency to spend. 

Understanding the basics starts with three questions: what are you trading, how is your profit or loss calculated, and what could go wrong?

What Is Forex Trading Used For?

Businesses exchange currencies to pay overseas suppliers. Investors use forex to manage currency exposure, while traders speculate on price movements. Protecting an investment against exchange-rate changes is known as currency hedging. 

Much of the forex market operates over the counter (OTC), through banks and dealers rather than one central exchange. According to the Bank for International Settlements (BIS), global FX turnover averaged approximately USD 9.5 trillion a day in April 2025. This includes spot transactions and derivatives, not just retail trading. 

How Does Forex Trading Work?

Currencies are quoted in pairs. For example, EUR/USD = 1.1000 means one euro is worth 1.1000 US dollars.

The first currency, EUR, is the base currency. The second, USD, is the quote currency, which expresses the base currency’s value. 

Buying EUR/USD, known as going long, expresses an expectation that the euro will strengthen against the dollar. Selling it, or going short, expresses the opposite view. A long position benefits from a rising exchange rate; a short position benefits from a falling rate, before costs. 

Other commonly traded pairs include GBP/USD, the British pound against the US dollar, and USD/JPY, the US dollar against the Japanese yen. 

Forex Trading vs Forex CFDs

The product matters. Exchanging money through a bank gives you foreign currency to hold or spend. A forex contract for difference (CFD) instead lets you speculate on a currency pair without owning the underlying currencies. Retail forex CFDs commonly use leverage, which increases exposure relative to the money committed. 

Forex Trading Example: From Prices to Profit

Before calculating a trade, understand the prices on your screen. The ask is the price at which you buy; the bid is the price at which you sell. Their difference is the spread. 

Price movements are measured in pips. One pip is usually 0.0001, although it is generally 0.01 for yen-quoted pairs such as USD/JPY. 

Position sizes are often expressed in lots. A standard lot commonly represents 100,000 units of the base currency, a mini lot 10,000 and a micro lot 1,000. 

Now suppose EUR/USD is quoted at 1.1000 / 1.1002. You expect the euro to strengthen and open a buy position equivalent to EUR 10,000, entering at the ask price of 1.1002.

The spread is 0.0002, or 2 pips.

Hypothetical outcome	Closing bid price	Calculation	Result
Close immediately, with prices unchanged	1.1000	(1.1000 − 1.1002) × 10,000	USD 2 loss
Close after the price rises	1.1050	(1.1050 − 1.1002) × 10,000	USD 48 profit
Close after the price falls	1.0950	(1.0950 − 1.1002) × 10,000	USD 52 loss

These illustrations exclude commissions, overnight financing and currency-conversion charges.

The initial USD 2 loss explains why a new position can start below zero. The spread is already reflected in these entry and exit prices, so it should not be subtracted again.

Some accounts also charge commissions, while positions held overnight may incur financing charges. Zero commission does not mean zero trading costs. 

What Causes Forex Prices to Move?

Exchange rates respond to changing supply and demand. Three influences are particularly useful for beginners to understand. 

Interest rates: Higher interest rates can attract investment into a currency, but the comparison with other economies matters. A country’s interest rate is only part of the picture, not a reliable signal on its own. 

Economic conditions: Growth, trade conditions and the relative economic outlook influence currency demand. New information can change how investors assess one economy compared with another.

Politics and market confidence: Trade policies and uncertainty can alter investment decisions. For example, the BIS linked increased FX activity in April 2025 partly to US tariff announcements and investors adjusting their currency hedges. 

The practical lesson is to compare both sides of a currency pair, rather than assume that one positive headline guarantees a rise.

When Can You Trade Forex?

The conventional forex market operates approximately 24 hours a day, five days a week, as activity moves between Asia-Pacific, European and North American financial centres. It generally closes over the weekend, although exact product hours and daily breaks depend on the broker. 

Is Forex Trading Risky?

Yes, particularly when leverage is involved. Leverage allows a larger position to be controlled with a smaller amount of capital, called margin. Profits and losses are based on the full position, not just the margin.

For example, at 10:1 leverage, USD 1,000 of margin supports a position worth USD 10,000. A 1% adverse movement would produce approximately USD 100 of losses before costs, equivalent to 10% of that margin.

Margin is not a fee or a guaranteed maximum loss. A broker may automatically close positions when the funds supporting them fall below required levels. Rules on leverage and loss protection vary by jurisdiction, provider and client classification. 

Sudden price changes can also cause slippage, when an order executes at a different price from the one expected. A stop-loss order is intended to close a position when a specified price level is reached, but an ordinary stop-loss does not guarantee the execution price. 

How to Start Learning Forex Trading

Start by studying one currency pair and practising order placement with virtual funds. Use demo practice to calculate position sizes, understand costs and record why you would enter or exit a trade. Do not treat demo profits as proof of future live results.

Before depositing, verify the exact company behind your account, its relevant regulatory permissions and its official contact details. Check these through the appropriate regulator’s register, rather than relying on a brand name alone. 

Build a trading plan that defines your position size, intended exit and acceptable loss before entering. Avoid committing money needed for essential expenses.

Conclusion

Understanding forex means more than predicting whether a currency will rise or fall. You also need to know what product you are trading, how costs affect the result and how much exposure you are taking.

Build that understanding before risking real money. Being able to explain a trade’s potential loss is just as important as calculating its possible profit.
