Know When to Buy or Sell a Currency Pair

Forex Trading Basics: What You Need to Know

What Is Forex Trading?

Forex (short for “foreign exchange” or simply “FX”) is the global marketplace where currencies are exchanged. It’s the largest and most liquid financial market in the world, where banks, institutions, and individual traders speculate on exchange rates.

How Does Forex Trading Work?

Forex trading involves predicting whether one currency will rise or fall in value against another. When you trade forex, you’re essentially buying one currency while selling another. This is done in pairs, such as EUR/USD or GBP/JPY.

A currency’s value can fluctuate based on economic indicators, political events, or market sentiment. Traders aim to profit by buying low and selling high—or vice versa.

Executing a forex trade is similar to trading in other financial markets. If you’ve traded stocks or commodities, you’ll find the process familiar. Even if you haven’t, forex platforms make it relatively easy to get started.

How to Profit from Forex Trading

The objective is to exchange one currency for another in anticipation that the price will move in your favor.

For example:

• You buy 10,000 EUR at an exchange rate of 1.1800 (EUR/USD).
• Two weeks later, you sell the same euros at 1.2500.
• Your profit: (1.2500 – 1.1800) × 10,000 = $700.

Understanding Forex Quotes

Currencies are always quoted in pairs, such as USD/JPY or GBP/USD. The first currency is called the base currency, and the second is the quote currency.

• The exchange rate shows how much of the quote currency you need to buy one unit of the base currency.
• Example: If GBP/USD = 1.21228, it means 1 GBP = 1.21228 USD.

Buying and Selling in Forex

• If you believe the base currency will rise, you buy the pair (go "long").
• If you think it will fall, you sell the pair (go "short").

You’re always simultaneously buying one currency and selling another.

Using Fundamentals to Trade Forex

Currency prices are influenced by macroeconomic factors like GDP growth, employment, interest rates, and trade balances. Since every currency belongs to a country or region, analyzing the health of an economy can help forecast currency strength.

For example:

• If you expect the U.S. economy to weaken, you might buy EUR/USD expecting the euro to strengthen against the dollar.
• If you expect strong Japanese exports and a weaker yen, you might buy USD/JPY anticipating the dollar will rise.

This type of analysis is called fundamental analysis and will be explored in more detail later.

Trading in Lots

Currencies are traded in standardized amounts called lots:

• Micro lot: 1,000 units
• Mini lot: 10,000 units
• Standard lot: 100,000 units

You don't need the full amount to trade thanks to margin and leverage.

Understanding Leverage and Margin

Leverage lets you control a large position with a small deposit (margin). For example:

• With 50:1 leverage, you only need $2,000 to control a $100,000 position.
• This amplifies gains—and losses.

Let’s say:

• You buy 100,000 units of GBP/USD at 1.50000 (value: $150,000).
• Margin requirement: 2% ($3,000).
• Price rises to 1.50500.
• Profit: $500 (a 16.67% return on your $3,000 margin).

But beware: high leverage can magnify losses too. A 100-pip drop with a $100,000 position could wipe out a $1,000 account.

Rollover and Interest Rates

When holding trades overnight, you may earn or pay interest depending on the interest rate differential between the two currencies in your pair.

• If you buy a currency with a higher interest rate than the one you’re selling, you might earn interest (positive rollover).
• If it’s the reverse, you may be charged interest (negative rollover).

Example:

• Buying USD/JPY could earn interest if U.S. rates exceed Japanese rates.

Rollover fees are applied at your broker’s cut-off time, typically 5:00 pm ET. Check with your broker for specific rates.
