Its volatility remains moderate to high, depending on the period, making it a good learning ground. It's a technical market, but not too complex for beginners well-trained.

It often requires a greater capital to effectively diversify your positions. Volatility is generally lower than in Forex, but movements can be slower.

Cryptocurrencies

Cryptos are available 24 hours a day, 7 days a week. Their volatility is very high, which can generate rapid gains, but also sudden losses.

Understanding a currency pair

Comprendre le fonctionnement d'une paire de devise

On the foreign exchange market, you don't buy a currency "on its own": you buy a currency "in its own right". currency against another. This is what we call a currency pair.

For example:
EUR/USD = 1.0850

This means that one euro is worth 1.0850 US dollars.
EUR is the base currency (the one you buy or sell).
USD is the quote currency (the one you pay with).

Comprendre le marché des devises

Trading a pair: buy or sell

When you open a position on a pair, you have two choices:

  • Buy (long) EUR/USD = you expect the euro will rise against the dollar.

  • Sell (short) EUR/USD = you expect the euro will fall against the dollar.

You place a buy or sell order on the basis of a technical analysiswhich you'll learn to do in the following chapters.

BID, ASK, SPREAD: concepts you really need to know

When you consult a price chart on your trading platform, you don't see just one price, but two:

  • The BID the price at which you can sell the pair

  • ASK the price at which you can buy the pair

  • What's the SPREAD in trading? It's the difference between these two prices.

The spread represents the entry fee of your trade. The lower it is, the better the market is for you.

Example:

  • EUR/USD Bid: 1.0848

  • EUR/USD Ask: 1.0850

  • Spread : 2 pips (i.e. 0.0002)

→ Un pip is the unit of minimum variation on most pairs (often the 4th decimal place, but it depends on the currency pair). This is how we measure market movements in Forex.

The three types of currency pairs

When you trade on the foreign exchange market, you have access to dozens of currency pairs. These are generally grouped into three main categoriesaccording to their popularity, trading volume and volatility.

1. Major pairs

These are the most widely traded on the Forex market. They include always the US dollar (USD)the world's most widely used currency. They are highly liquid, well-analyzed, and generally have the lowest spreads - perfect for learn to trade currencies.

Here are a few examples:

  • EUR/USD The most traded pair in the world. It alone accounts for around 30 % of Forex volume.

  • GBP/USD Also known as "Cable". More volatile than EUR/USD.

  • USD/JPY Very active during the Asian session. It often reflects the overall mood of the market.

  • USD/CHF Stable, often used as a safe haven.

→ Why start with major pairs?

  • Very low spreads (less than 2 pips on EUR/USD)

  • Maximum liquidity = fast order execution

  • More regular and predictable movements

2. Minor (or crossed) pairs

These pairs cross two currencies not including the U.S. dollar. Trading volume is lower than on the majors, and spreads can be a little higher. They are interesting, but require a little more experience.

Examples of minor pairs:

  • EUR/GBP Less volatile, interesting for observing economic differences between Europe and the UK.

  • EUR/JPY More mobile, often used for medium-term strategies.

  • GBP/JPY Highly volatile. Reserved for more advanced traders.

→ Please note: minor pairs react to several savings at the same timeThis means keeping up to date with the latest economic news.

3. Exotic pairs

These pairs combine a major currency (such as the euro or the dollar) to a foreign currency. emerging country or less liquid (such as the Turkish lira, South African rand or Mexican peso).

Examples:

  • USD/TRY (dollar/Turkish lira)

  • EUR/ZAR (euro/South African rand)

  • USD/MXN (dollar/Mexican peso)

To be avoided as a beginner:

  • Very high spreads (sometimes 50 to 100 pips)

  • High volatility, sudden movements

  • Low liquidity = slippage and sometimes poor execution

  • More complex analysis, due to lack of reliable information

What influences the exchange rate?

Qu'est ce qui influence le marché du forex

For investing in Forex it is essential to understand which influences currency fluctuations. Contrary to popular belief, it's not traders who move the market, but global economic, political and psychological factors.

Here are the most important ones to know:

1. Supply and demand

As in any market, the price of a currency depends on the balance between those who want to buy it... and those who want to sell it.

➤ The more a currency is in demand (e.g. because the country's economy is in good shape), the more its value increases.
➤ Conversely, if investors flee a currency, its price is falling.

2. Major economic announcements

Some publications have a direct and immediate impact on currencies. These are high-stakes moments for traders.

The most watched :

  • Unemployment rate

  • Inflation (CPI)

  • GDP

  • Balance of trade

  • Monetary policy decisions

→ These announcements are known in advance thanks to the economic calendar, which you'll learn to read in the next chapters.

3. Central banks

Decisions and speeches by central banks such as ECB (Europe), the Fed (United States), or the BoJ (Japan) may cause the foreign exchange market to react in just a few seconds.

Why? Because they directly influence :

  • Visit interest rate

  • Money supply trends

  • Investor confidence in the country's economy

4. Macroeconomic indicators

A good Forex trader needs to keep an eye on :

  • Visit key rates

  • Visit economic growth

  • Visit public debt

  • The general political climate

All these elements give signals about the strength of a currency.

5. Geopolitical context and market sentiment

This is why certain assets are called "safe-havenssuch as :

  • Visit yen (JPY)

  • Visit Swiss franc (CHF)

  • Visit US dollar (USD) in times of global crisis
