While a lot of foreign exchange is done for practical purposes, the vast majority of currency conversion is undertaken by forex traders to earn a profit. The amount of currency converted every day can make price movements of some currencies extremely volatile – which is something to be aware of before you start forex trading.

What is a forex pair?

A forex pair is a combination of two currencies that are traded against each other. There are hundreds of different combinations to choose from, but some of the most popular include the euro against the US dollar (EUR/USD), the US dollar against the Japanese yen (USD/JPY) and the British pound against the US dollar (GBP/USD).

What are the base and quote currencies?

The base currency is always on the left of a currency pair, and the quote is always on the right. The base currency is always equal to one, and the quote currency is equal to the current quote price of the pair – which shows how many of the quote currency it’ll cost to buy one of the base. So, when you’re trading currency, you’re always selling one to buy another.

What is a pip in forex?

A pip in forex is usually a one-digit movement in the fourth decimal place of a currency pair. So, if GBP/USD moves from $1.35361 to $1.35371, then it has moved a single pip. But, if you’re trading JPY crosses, a pip is a change at the second decimal place. A price movement at the fifth decimal place in forex trading is known as a pipette.

What is a lot in forex trading?

Currencies are traded in lots, which are batches of currency used to standardise forex trades. As forex price movements are usually small, lots tend to be very large. For example, a standard lot is 100,000 units of the base currency.

How does forex trading work?

Forex trading works like any other transaction where you are buying one asset using a currency. In the case of forex, the market price 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 shows how many US dollars it would take to buy one pound.

Each currency has its own code – which lets traders quickly identify it as part of a pair. We’ve included codes for some of the most popular currencies below.

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

    To buy a currency pair means that you expect the price to rise, indicating that the base currency is strengthening relative to the quote currency. To sell a currency pair means that you expect the price to fall, which would happen if the base currency weakened against the quote.

    For example, you’d ‘buy’ the GBP/USD pair if you think that the pound will strengthen against the dollar – meaning you’ll need more dollars to buy a single pound. Or, you’d ‘sell’ this pair if you think that the pound will weaken against the dollar – meaning you’ll need fewer dollars to buy a single pound.

  • What is the spread in forex trading?

    The spread in forex trading is the difference between the buy and sell prices. For example, the buy price might be 1.3428 and the sell price might be 1.3424. For your position to be profitable, you’ll need the market price to either rise above the buy price or fall below the sell price – depending on whether you’ve gone long or short.

  • What are margin and leverage in FX trading?

    Margin refers to the initial deposit you need to commit in order to open and maintain a leveraged position. So, a trade on EUR/GBP might only require a 3.33% margin in order for it to be opened. As a result, instead of needing £100,000 to open a position, you’d only need to deposit £3300.

Why do people trade forex?

  • Speculating on currencies strengthening or weakening
  • Hedging with forex
  • Seize opportunity 24 hours a day

Speculating on currencies strengthening or weakening

Traders speculate on forex pairs to profit from one currency strengthening or weakening against another. When the price of a pair is rising, it means that the base is strengthening against the quote and when it’s falling, the base is weakening against the quote.

That’s because a rising price means that more of the quote are needed to buy a single unit of the base, and a falling price means that fewer of the quote are needed to buy one of the base. So, traders would likely go long if the base is strengthening relative to the quote currency, or short if the base is weakening.

Some of the most popular forex trading styles are scalping, day trading, swing trading and position trading. You might choose a different style depending on whether you have a short- or long-term outlook.

Hedging with forex

Hedging is a way to mitigate your exposure to risk. It’s achieved by opening positions that will stand to profit if some of your other positions decline in value – with the gains hopefully offsetting at least a portion of the losses. Currency correlations are effective ways to hedge forex exposure. An example would be EUR/USD and GBP/USD, which are positively correlated because they tend to move in the same direction. So, you could go short on GBP/USD if you had a long EUR/USD position to hedge against potential market declines.

Seize opportunity 24 hours a day

The forex market is open 24 hours a day thanks to the global network of banks and market makers that are constantly exchanging currency. The main sessions are the US, Europe and Asia, and it’s the time differences between these locations that enables the forex market to be open 24 hours a day.

What moves the forex market?

The forex market is made up of currencies from all over the world, which can make exchange rate predictions difficult as there are many forces that can contribute to price movements. That said, the following factors can all have an effect on the forex market.

Supply and demand

Exchange rates for forex pairs are based on the supply and demand of one currency versus another. In basic terms, if demand for one currency is greater than another then the price of the first currency will rise against the second.

The below factors all feed into what influences supply and demand.

Central banks

A currency’s supply is controlled by central banks, who can announce measures that will have a significant effect on that currency’s price.

Central banks choose whether to increase or decrease interest rates. Typically when a country chooses to raise interest rates, the country's currency may increase in value. This is because it attracts foreign investors who want to benefit from the higher interest rates.

Quantitative easing, meanwhile, involves injecting more money into an economy, and can cause a currency’s price to fall in line with an increased supply.

Interest rates and carry trades

One of the more popular investments among institutional investors is called a carry trade - based on interest rate differentials between countries.

This involves selling a currency with a low interest rate, with the goal of using the proceeds to buy a currency with a higher interest rate. This aims to capture the difference between the rates.

Fiscal policy

This is how governments influence the levels and allocations of taxes and public spending. The currency of a country with, for example, a high debt ratio and low growth is likely to be sold off. FX traders may instead prefer to buy a currency of a country with lower debt and higher growth.

International trade

Both anticipated and actual international trade between countries also influences FX prices. For example, a currency from a country with a trade deficit could be worth less than one with a trade surplus.

This is because a country with a trade deficit imports more goods and services than it exports - and therefore needs to buy the currencies of its trading partners to pay for these imports.

News reports and market sentiment

Commercial banks and other investors tend to want to put their capital into economies that have a strong outlook. So, if a positive piece of news hits the markets about a certain region, it will encourage investment and increase demand for that region’s currency. If negative news hits, then demand might be expected to fall. This is why currencies tend to reflect the reported economic health of the region they represent.

Market sentiment, which often reacts to the news, can also play a major role in driving currency prices. If traders believe that a currency is headed in a certain direction, they will trade accordingly and may convince others to follow suit, increasing or decreasing demand.

Learn the ways to trade forex

There are several ways to trade forex, including trading spot forex, forex forwards and currency options. When you trade with us, you’ll be speculating on the price of spot forex, forwards and options either rising or falling with a spread betting or CFD account.

  • Spot forex trading lets you trade forex pairs at their current market price with no fixed expiries
  • Forex or currency forwards enable you to trade forex pairs at a specified price to be settled at a set date in the future or within a range of future dates
  • Forex or currency options let you trade contracts that give the holder the right, but not the obligation, to buy or sell a currency pair at a set price, if it moves beyond that price within a set time frame

All of these – spot, forwards and options – can be traded with FX spread bets and FX CFDs. These are financial derivatives which let you speculate on whether prices will rise or fall without having to own the underlying asset.

What is a forex broker?

A forex broker provides access to trading platforms that can be used to buy and sell currencies. For example, when you trade forex with us, you’ll be able to use our award-winning platform8 or MT4 – both of which have their own unique benefits.

Forex brokers charge a fee, usually in the form of a spread. This is the difference between the buy (offer) and sell (bid) prices, which are wrapped around the underlying market price. The costs for a trade are factored into these two prices, so you’ll always buy slightly higher than the market price and sell slightly below it.

Traditionally, a forex broker would buy and sell currencies on behalf of their clients or retail traders. But, with the rise of online trading, you can buy and sell currencies yourself with financial derivatives like spread bets and CFDs, so long as you have access to a trading platform. This is because all forex trades are conducted over-the-counter (OTC), rather than on exchange like stocks.

Discover the risks and rewards of trading forex

  • Forex is the most-traded financial market in the world, which means that forex prices are constantly moving, creating more opportunities to trade
  • Some forex pairs are more volatile than others. Those with low liquidity are often more volatile, including many ‘minor’ pairs
  • Pairs that include USD are often more liquid because as the world’s reserve currency, USD is often in high demand
  • Slippage is sometimes an issue in forex trading, given how volatile the market can be. To help mitigate the effects of slippage on your forex trades, you should add stops and limits
  • But, if you are aware of the risks and take appropriate steps to mitigate your exposure, then the forex market can be the source of your next opportunity
