Currency Pairs: Forex Trading Basics for Beginners

Introduction to the Forex market

The forex market (Foreign Exchange Market) is the largest financial market in the world, with daily volume exceeding 7.5 trillion US dollars. For comparison — the New York Stock Exchange records a daily volume of around 30-40 billion dollars. The difference is colossal: the currency market is more than 200 times larger than the world's biggest stock exchange. This enormous liquidity means that even the largest transactions have minimal impact on prices, making forex attractive to traders of any capital size.

The forex market is decentralised — there is no single physical location or central exchange. Transactions are executed electronically through a network of banks, brokers, hedge funds and retail traders connected in an interbank system. Trading runs 24 hours a day, 5 days a week — from Monday morning in Sydney to Friday afternoon in New York.

Currencies are traded exclusively in pairs — by buying one, you simultaneously sell the other. That is the fundamental principle of forex: every transaction has two sides. When you buy EUR/USD, you acquire euros and simultaneously sell US dollars. You are betting that the euro will gain value against the dollar. Conversely — selling EUR/USD means selling euros and buying dollars, counting on the euro to weaken.

The forex market has no exchange — it is a network of banks, brokers and traders connected electronically. This decentralisation provides 24/5 liquidity.

Types of currency pairs

Currency pairs fall into three main categories, each with a different risk profile, liquidity and transaction costs. Understanding these categories is the basis of an informed choice of instruments.

Major pairs (Majors) contain the US dollar on one side. The majors include EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD and USD/CAD. EUR/USD is the most liquid pair in the world — it accounts for around 25% of all forex transactions. Major pairs feature the lowest spreads (often 0.5-1.2 pips at ECN brokers), the highest liquidity and the lowest slippage risk. They are the ideal starting point for any beginner trader.

Cross pairs (Minors/Crosses) do not contain the US dollar. Examples include EUR/GBP, EUR/JPY, GBP/JPY, AUD/NZD, EUR/CHF. These pairs trade on a cross rate — their value is derived from each currency's relationship to the USD. Cross pairs have slightly higher spreads (1-3 pips) and lower liquidity, but they offer unique opportunities — GBP/JPY, for example, is known as "The Beast" for its high volatility and wide daily price ranges.

Exotic pairs (Exotics) combine a major currency with the currency of a developing country. Examples: USD/TRY (dollar/Turkish lira), EUR/PLN (euro/Polish zloty), USD/ZAR (dollar/South African rand). Exotic pairs have high spreads (10-100+ pips), lower liquidity and greater volatility. They are difficult for beginners to trade because of high transaction costs and the risk of price gaps.

How to read an exchange rate

Every currency pair consists of a base currency and a quote currency. In the EUR/USD pair, the euro is the base currency and the dollar is the quote currency. A rate of 1.0850 means that 1 euro costs 1.0850 US dollars. You always buy or sell units of the base currency, and the price is expressed in the quote currency.

Every forex transaction has two prices: the bid (sell price) and the ask (buy price). The bid is the price at which the broker will buy the base currency from you — the price at which you close a long position. The ask is the price at which the broker sells you the base currency — the opening price of a long position. The bid is always lower than the ask — the difference is the spread.

A practical example: EUR/USD quotes a bid of 1.08492 and an ask of 1.08498. You open a long position at 1.08498 (the ask). For the trade to be profitable, the price must rise above 1.08498. When the price reaches 1.08520, you close the position at the 1.08520 bid. The profit is 22 pips minus the 0.6-pip spread = 21.4 pips net.

Pip, spread and lot — the language of forex

A pip (Percentage in Point) is the smallest unit of price change in most currency pairs — usually the fourth digit after the decimal point. When EUR/USD moves from 1.0850 to 1.0851, that is a 1-pip move. The exception is pairs with the Japanese yen (JPY), where a pip is the second digit after the decimal point (e.g. 149.50 → 149.51 = 1 pip). Most brokers now quote to the fifth decimal place (a pipette), i.e. 0.1 pip.

The spread is the difference between the ask and bid prices — your basic transaction cost. On EUR/USD at ECN brokers, the spread is often 0.2-1.0 pips. On cross pairs 1-3 pips, on exotics 10-100+ pips. The spread is not fixed — it widens during low liquidity (nights, holidays) and around major macroeconomic events. Never open a position right before a data release — the spread can widen 5-10 times.

A lot is the unit of position size. A standard lot is 100,000 units of the base currency, a mini lot (0.1) is 10,000, a micro lot (0.01) is 1,000. With a standard lot on EUR/USD, 1 pip ≈ 10 USD. With a mini lot 1 pip ≈ 1 USD, with a micro lot 1 pip ≈ 0.10 USD. On a $10,000 account, micro lots let you risk a sensible amount — a 50-pip loss at 0.01 lots is only about 5 USD.

Leverage and margin in forex

Trading forex requires a deposit called margin. Margin is the amount locked on your account as "collateral" for an open position. At 1:30 leverage (the maximum for major pairs in the EU under ESMA), to open a position worth 30,000 USD you only need 1,000 USD of margin. The remaining funds on the account are the "free margin", which covers potential losses.

The margin level is a percentage indicator showing the ratio of free capital to locked margin. When the margin level falls below the Margin Call threshold (usually 100%), the broker starts closing positions automatically — the so-called Stop Out. Keep your margin level above 200% for safety. In multi-position trading, the total margin of all open positions must be monitored constantly.

The overnight holding cost (swap) is a fee or credit applied for keeping a position open overnight. The swap arises from the interest rate differential between the two currencies. If the interest rate of the currency you bought is higher, you receive the swap (positive). If lower — you pay the swap (negative). For day traders the swap is irrelevant; for swing traders it can significantly affect results.

A practical example: your first EUR/USD trade

Let us walk through a full trade cycle. You have an account with a $20,000 balance. You decide on a long position on EUR/USD at 1.08500. You set a stop-loss at 1.08200 (30 pips of risk) and a take-profit at 1.09100 (60 pips of profit — an R:R ratio of 1:2).

You risk 1% of your capital, i.e. $200. With a 30-pip stop-loss and a pip value of about $0.80 at 0.1 lots, your position is 0.1 lots (10,000 EUR). When the price reaches 1.09100, you close with a profit of 60 pips × $0.80/pip = $480. After deducting the spread (about 1 pip = $0.80) and any swap, the net profit is around $470.

The alternative scenario: the price falls to 1.08200. The stop-loss closes the position with a loss of 30 pips × $0.80/pip = $240. That is less than 1.2% of your capital — within acceptable risk. The key point is that you knew these numbers before you opened the position, not after the fact.

Remember: in forex you do not have to be right often. With an R:R ratio of 1:2, a 34% win rate is enough to be profitable. The quality of decisions outweighs their quantity.

Summary: the forex learning path

Forex trading is a marathon, not a sprint. Start by understanding the basics: how currency pairs work, and what pip, spread and lot mean. Then open a demo account and spend at least 3 months practising without risk. Test different major pairs, experiment with position sizes and learn to read the charts.

Key steps at the start: choose a regulated broker with low spreads on EUR/USD, open a demo account, learn to read currency pairs and calculate pip values, set a stop-loss on every trade and keep a trading journal. Discipline and patience are your greatest edge in the market.
