What Is Forex (FX)?

Forex (FX) refers to the global electronic marketplace for trading international currencies and currency derivatives. It has no central physical location, yet the forex market is the largest, most liquid market in the world by trading volume, with trillions of dollars changing hands every day. Most of the trading is done through banks, brokers, and financial institutions.

The forex market is open 24 hours a day, five days a week, except for holidays. The forex market is open on many holidays on which stock markets are closed, though the trading volume may be lower.

Its name, forex, is a portmanteau of foreign and exchange. It’s often abbreviated as fx.

Key Takeaways

• Forex (FX) market is a global electronic network for currency trading.
• Formerly limited to governments and financial institutions, individuals can now directly buy and sell currencies on forex.
• In the forex market, a profit or loss results from the difference in the price at which the trader bought and sold a currency pair.
• Currency traders do not deal in cash. Brokers generally roll over their positions at the end of each day.

Understanding Forex (FX)

Forex traders use various analysis techniques to find the best entry and exit points for their trades. Forex exists so that large amounts of one currency can be exchanged for the equivalent value in another currency at the current market rate.

Some of these trades occur because financial institutions, companies, or individuals have a business need to exchange one currency for another. For example, an American company may trade U.S. dollars for Japanese yen in order to pay for merchandise that has been ordered from Japan and is payable in yen.

A great deal of forex trade exists to accommodate speculation on the direction of currency values. Traders profit from the price movement of a particular pair of currencies.

Forex Pairs and Quotes

Currencies being traded are listed in pairs, such as USD/CAD, EUR/USD, or USD/JPY. These represent the U.S. dollar (USD) versus the Canadian dollar (CAD), the Euro (EUR) versus the USD, and the USD versus the Japanese Yen (JPY), respectively.

There will also be a price associated with each pair, such as 1.2569. If this price was associated with the USD/CAD pair it means that it costs 1.2569 CAD to buy one USD. If the price increases to 1.3336, it now costs 1.3336 CAD to buy one USD. The USD has increased in value (the CAD has decreased) as it now costs more CAD to buy one USD.

Forex Lots

In the forex market, currencies trade in lots called micro, mini, and standard lots. A micro lot is 1,000 units of a given currency, a mini lot is 10,000, and a standard lot is 100,000.

This is obviously exchanging money on a larger scale than going to a bank to exchange $500 to take on a trip. When trading in the electronic forex market, trades take place in blocks of currency, and they can be traded in any volume desired, within the limits allowed by the individual trading account balance. For example, you can trade seven micro lots (7,000) or three mini lots (30,000), or 75 standard lots (7,500,000).

How Large Is the Forex?

The forex market is unique for several reasons, the main one being its size. Trading volume is generally very large. The Forex market trades over $5 trillion per day compared to $200 billion for the equities market.

The largest foreign exchange markets are located in major global financial centers including London, New York, Singapore, Tokyo, Frankfurt, Hong Kong, and Sydney.

How to Trade Forex

The forex market is open 24 hours a day, five days a week, in major financial centers across the globe. This means that you can buy or sell currencies at virtually any hour.

In the past, forex trading was largely limited to governments, large companies, and hedge funds. Now, anyone can trade on forex. Many investment firms, banks, and retail brokers allow individuals to open accounts and trade currencies.

When trading in the forex market, you’re buying or selling the currency of a particular country, relative to another currency. But there’s no physical exchange of money from one party to another as at a foreign exchange kiosk.

In the world of electronic markets, traders usually take a position in a specific currency with the hope that there will be some upward movement and strength in the currency they’re buying (or weakness if they’re selling) so that they can make a profit.

A currency is always traded relative to another currency. If you sell a currency, you are buying another, and if you buy a currency you are selling another. The profit is made on the difference between your transaction prices.

Spot Transactions

A spot market deal is for immediate delivery, which is defined as two business days for most currency pairs. The major exception is the purchase or sale of USD/CAD, which is settled in one business day.

The business day excludes Saturdays, Sundays, and legal holidays in either currency of the traded pair. During the Christmas and Easter seasons, some spot trades can take as long as six days to settle. Funds are exchanged on the settlement date, not the transaction date.

The U.S. dollar is the most actively traded currency. The euro is the most actively traded counter currency, followed by the Japanese yen, British pound, and Chinese renminbi.

Market moves are driven by a combination of speculation, economic strength and growth, and interest rate differentials.

Forex Rollover

Retail traders don’t typically want to take delivery of the currencies they buy. They are only interested in profiting from the difference between their transaction prices. Because of this, most retail brokers will automatically «roll over» their currency positions at 5 p.m. EST each day.

The broker basically resets the positions and provides either a credit or debit for the interest rate differential between the two currencies in the pairs being held. The trade carries on and the trader doesn’t need to deliver or settle the transaction.

When the trade is closed the trader realizes a profit or loss based on the original transaction price and the price at which the trade was closed. The rollover credits or debits could either add to this gain or detract from it.

Since the forex market is closed on Saturday and Sunday, the interest rate credit or debit from these days is applied on Wednesday. Therefore, holding a position at 5 p.m. on Wednesday will result in being credited or debited triple the usual amount.

Forex Forward Transactions

Any forex transaction that settles for a date later than spot is considered a forward. The price is calculated by adjusting the spot rate to account for the difference in interest rates between the two currencies. The amount of adjustment is called «forward points.»

The forward points reflect only the interest rate differential between two markets. They are not a forecast of how the spot market will trade at a date in the future.

A forward is a tailor-made contract. It can be for any amount of money and can settle on any date that’s not a weekend or holiday. As in a spot transaction, funds are exchanged on the settlement date.

Forex Futures

A forex or currency futures contract is an agreement between two parties to deliver a set amount of currency at a set date, called the expiry, in the future. Futures contracts are traded on an exchange for set values of currency and with set expiry dates.

Unlike a forward, the terms of a futures contract are non-negotiable. A profit is made on the difference between the prices the contract was bought and sold at.

Most speculators don’t hold futures contracts until expiration, as that would require they deliver/settle the currency the contract represents. Instead, speculators buy and sell the contracts prior to expiration, realizing their profits or losses on their transactions.

How Forex Differs From Other Markets

There are some major differences between the way the forex operates and other markets such as the U.S. stock market.

Fewer Rules

This means investors aren’t held to as strict standards or regulations as those in the stock, futures, or options markets. There are no clearinghouses and no central bodies that oversee the entire forex market. You can short-sell at any time because in forex you aren’t ever actually shorting; if you sell one currency you are buying another.

Fees and Commissions

Since the market is unregulated, fees and commissions vary widely among brokers. Most forex brokers make money by marking up the spread on currency pairs. Others make money by charging a commission, which fluctuates based on the amount of currency traded. Some brokers use both.

Full Access

There’s no cut-off as to when you can and cannot trade. Because the market is open 24 hours a day, you can trade at any time of day. The exception is weekends, or when no global financial center is open due to a holiday.

Leverage

The forex market allows for leverage up to 1:50 in the U.S. and even higher in some parts of the world. That means a trader can open an account for $1,000 and buy or sell as much as $50,000 in currency. Leverage is a double-edged sword; it magnifies both profits and losses.

Example of Forex Transactions

Assume a trader believes that the EUR will appreciate against the USD. Another way of thinking of it is that the USD will fall relative to the EUR.

The trader buys the EUR/USD at 1.2500 and purchases $5,000 worth of currency. Later that day the price has increased to 1.2550. The trader is up $25 (5000 * 0.0050). If the price dropped to 1.2430, the trader would be losing $35 (5000 * 0.0070).

About the Rollover

Currency prices move constantly, so the trader may decide to hold the position overnight. The broker will roll over the position, resulting in a credit or debit based on the interest rate differential between the Eurozone and the U.S.

If the Eurozone has an interest rate of 4% and the U.S. has an interest rate of 3%, the trader owns the higher interest rate currency in this example. Therefore, at rollover, the trader should receive a small credit. If the EUR interest rate was lower than the USD rate, the trader would be debited at rollover.

Rollover can affect a trading decision, especially if the trade can be held for the long term. Large differences in interest rates can result in significant credits or debits each day, which can greatly enhance or erode profits (or increase or reduce losses) of the trade.

Most brokers provide leverage. Many U.S. brokers leverage up to 1:50. Let’s assume our trader uses 1:10 leverage on this transaction. If using 10:1 leverage the trader is not required to have $5,000 in an account, even while trading $5,000 worth of currency. Only $500 is needed.

In this example, a profit of $25 can be made quite quickly considering the trader only needs $500 or $250 of trading capital (or even less if using more leverage). That shows the power of leverage. The flip side is that the trader could lose the capital just as quickly.

Is Forex Trading for Beginners?

Forex trading can be risky and complex, involving quick decisions due to how fast exchange rates change. It is likely not suited for beginner traders; however, traders can spend time learning forex trading with test trading or with low levels of capital.

How Much Do You Need to Start Trading Forex?

You can start trading Forex with around $100. This will be enough to get you started in buying and selling currencies. It is also a good level for beginners as it isn’t a very large amount of capital to lose.

What Are the Risks of Forex Trading?

There are many risks to forex trading. Exchange rates are very volatile, changing often, which could quickly impact a trade. There is also a significant amount of leverage involved in FX, meaning small movements can result in large losses. In addition, there is transaction risk, interest rate risk, and global or country risk.

The Bottom Line

Forex is foreign exchange, which refers to the global trading of currencies and currency derivatives. It is the largest financial market in the world, involving the buying and selling of currencies in pairs, taking advantage of changing rates.
