What is Forex in forex and CFD trading

Forex (Foreign Exchange) is the global decentralized market for the trading of currencies, determining foreign exchange rates for every currency; it is the largest and most liquid financial market in the world. The Forex market matters for real trading decisions because it defines the price of currency pairs, which are the fundamental instruments in both spot forex and CFD trading, reflecting economic conditions, interest rate differentials, and political stability. A trader can verify or measure the Forex market’s current state by observing the bid and ask prices, the spread, and the transaction volume for any given currency pair on their trading platform. The term Forex is often used interchangeably with the FX market. You can explore other trading terms in our full glossary.

Key facts about Forex

• Market Size: Over $7.5 trillion average daily trading volume, as of April 2022, making it the most liquid financial market globally.
• Trading Structure: Operates over-the-counter (OTC), meaning transactions occur directly between two parties; not through a centralized exchange.
• Primary Instruments: Currency pairs, categorized as Majors (e.g., EUR/USD, GBP/USD), Minors or Crosses (e.g., EUR/JPY), and Exotics.
• Trading Hours: The Forex market is open 24 hours a day, five days a week, from Sunday evening (GMT) until Friday evening (GMT).
• Standard Unit: The lot, where one standard lot equals 100,000 units of the base currency.
• Price Movement: Measured in pips (percentage in point), which is typically the fourth decimal place in a currency pair quote; or the second decimal place for JPY pairs.
• Governing Body: There is no single international regulatory body; regulation is local and performed by national authorities like the FCA, ASIC, and CySEC.

How Forex works in forex and CFD trading

The process involves the simultaneous buying of one currency and selling of another, represented as a currency pair. In the pair EUR/USD, the Euro (EUR) is the base currency and the US Dollar (USD) is the quote currency.

The mechanics are as follows:

• Quote Formation: A broker or liquidity provider generates a two-way quote consisting of a Bid (the price at which the broker will buy the base currency, meaning the trader sells) and an Ask (the price at which the broker will sell the base currency, meaning the trader buys).
• Trade Execution: A trader places an order, for example, to buy EUR/USD. The order is executed at the Ask price.
• Liquidity Aggregation: For retail traders, brokers typically aggregate pricing from multiple liquidity providers (Tier-1 banks, investment firms) to ensure continuous execution and competitive spreads, particularly in high-volume Forex markets.
• Profit/Loss Calculation: The profit or loss is calculated based on the difference between the entry price and the exit price, multiplied by the position size.
• Pip Value Calculation: Pip Value = (One Pip in Decimal / Exchange Rate) × Lot Size (for pairs where the quote currency is the account currency). For EUR/USD, a one-pip move on a standard lot is usually $10.

Example of Forex with a real trade

The following example demonstrates the cost and PnL calculation for a simple trade in the Forex market.

• Open Position: Buy 1 standard lot of EUR/USD. Entry Ask Price: 1.0750 Position size: 1 standard lot (100,000 units)
• Close Position: Sell the position to close the trade. Exit Bid Price: 1.0800

Calculation:

• Price difference (profit in pips): 1.0800 – 1.0750 = 0.0050, or 50 pips.
• Value per pip: $10 (for a standard lot of EUR/USD)
• Gross Profit: 50 pips × $10/pip = $500
• Commission Cost: $0 (zero commission structure)
• Net Profit: $500

Result: The trade generates a net profit of $500 from the movement in the Forex price, with zero commission preserving the full pip value.

How Forex affects your cost and risk

The structure of the Forex market fundamentally affects a trader’s cost and risk by dictating execution costs, primarily through the spread, and by determining margin requirements based on volatility. Higher volatility in a Forex pair can lead brokers to increase margin requirements to mitigate their own risk exposure.

Forex compared with related concepts

Forex vs CFD

Forex trading, in the retail context, typically refers to the trading of spot currency pairs, whereas a CFD (Contract for Difference) is a broader instrument that allows a trader to speculate on the price movement of an underlying asset, which may be a currency pair, stock index, or commodity; the core mechanism of the Forex market is the underlying pricing for all currency CFDs.

Forex vs Futures Market

The Forex market is decentralized and over-the-counter, with prices set by liquidity providers, while the Futures Market is centralized on an exchange, with standardized contract sizes and expiration dates; the OTC Forex market offers greater flexibility in position sizing and trade duration compared to regulated currency futures contracts.

Broker differences in Forex across the industry

Brokerage models significantly impact the price and execution a trader receives in the Forex market, reflecting different approaches to risk and pricing.

How to verify Forex on your trading platform

A trader must constantly verify the current pricing and liquidity of the Forex instruments they trade to manage execution risk; the process below focuses on the MetaTrader 5 (MT5) platform.

• Open Market Watch: Open the Market Watch window in MT5, which displays the list of tradable currency pairs.
• View Symbol Specification: Right-click on the EUR/USD symbol and select Specification to view contract details like spread type and margin settings.
• Display Spread Column: Right-click again on the Market Watch and select Columns > Spread to show the current, dynamic spread in pips for all Forex pairs.
• Check Ask Line on Chart: Navigate to the Chart for EUR/USD and ensure the Ask line is visible; this visually shows the spread gap between the Bid and Ask prices.
• Check Depth of Market (DOM): Check the Depth of Market (DOM) window if available for institutional accounts; this displays current liquidity and the price levels available from liquidity providers for the Forex pair.
• Execute a Test Order: Place a small test order to confirm the executed price aligns with the advertised Ask price for a buy order, verifying the broker’s execution quality.

Sanity check: On a major pair like EUR/USD during core trading hours, the dynamic spread should typically be less than 1.0 pip on an institutional-grade account.
