Forex Trading Guide for Beginners

How forex trading works is easier to grasp once you drop the jargon. You exchange one currency for another, hoping the rate moves in your favour before you swap back. Everything else (pips, lots, leverage, swaps) is detail about measuring and financing that exchange.

Reading a currency quote

Currencies are quoted in pairs. In GBP/USD 1.2650, one British pound costs 1.2650 US dollars. The first currency is the base; the second is the quote currency. Buying the pair means buying pounds and paying in dollars. Selling it means the opposite, and you can do that without owning pounds first.

Every quote has two prices. The bid is what the provider will pay you if you sell; the ask is what you pay to buy. The gap is the spread, and it is the first cost of every trade. If GBP/USD shows 1.2649 / 1.2651, the spread is 2 pips.

Pairs fall into three groups. Majors include the US dollar and another widely traded currency, such as EUR/USD or USD/JPY. Minors or crosses pair two non-dollar currencies, such as EUR/GBP. Exotics combine a major currency with one from a smaller economy; their spreads are usually much wider.

Pips and lots: how moves become money

A pip is the standard unit of movement: 0.0001 for most pairs and 0.01 for pairs quoted in Japanese yen. A standard lot is 100,000 units of the base currency; mini (10,000) and micro (1,000) lots are also common. For any pair quoted in US dollars, one pip on one standard lot is worth $10.

So a move that looks tiny on the chart can be large in cash. A 50-pip move on two standard lots is worth $1,000. Our pip calculator does this conversion for any pair, including yen and cross pairs where the value changes with the exchange rate.

Leverage and margin, without the sales pitch

Because currencies move in small steps, retail forex is almost always traded with leverage: you put down a deposit, called margin, and control a larger position. Regulators have capped this for retail clients. In the UK, EU and Australia the limit is 30:1 on major pairs and 20:1 on other pairs; in the US it is 50:1 on majors and 20:1 on others.

Leverage does not change how far the price moves; it changes how much of your balance each move represents. At 30:1, a 1% move against a fully leveraged position wipes out 30% of the margin behind it. Providers in the UK and EU must close positions when your margin level falls to 50% of the required amount, and retail clients there are protected from a negative balance. Offshore firms often promise leverage of several hundred to one with neither safeguard.

Use the margin calculator to see how much of your balance a trade locks up, and the position size calculator to size it from the loss you can accept.

How forex trading works on one trade (illustrative numbers)

Suppose you buy 0.3 lots of GBP/USD at 1.2650 with a stop-loss at 1.2620 and a target at 1.2710.

• Pip value: 0.3 × 100,000 × 0.0001 = $3 per pip.
• Distance to the stop: 30 pips, so the planned loss is 30 × $3 = $90, plus costs.
• Distance to the target: 60 pips, so the planned gain is 60 × $3 = $180, before costs.
• Position value: 0.3 × 100,000 × 1.2650 = $37,950. At 30:1 the margin required is $1,265.

A stop-loss is an instruction, not a guarantee. If the price jumps over your level, for example after a surprise announcement or over a weekend, the order fills at the next available price and the loss can be larger than planned.

Trading sessions and why timing changes costs

The market opens on Sunday at 17:00 New York time, as Asia-Pacific centres begin their Monday, and closes on Friday at 17:00 New York time. Activity moves from Sydney and Tokyo to London and then New York. Spreads are usually tightest when London and New York are both open and widest around the daily rollover at 17:00 New York time, when liquidity thins out.

Positions still open at the rollover pay or receive an overnight financing charge, often called a swap. Many providers apply three days' worth on Wednesday night to cover the weekend. The fees guide explains how these charges add up over weeks.

What moves exchange rates

• Interest-rate expectations. Central bank decisions and the language around them are the single biggest driver of major pairs.
• Scheduled data. Inflation, employment and growth figures are released on published calendars and can move prices sharply within seconds.
• Risk appetite. In stressed markets, money has historically tended to flow towards currencies seen as safe, which can move pairs regardless of the economic data.
• Unscheduled events. Elections, policy surprises and conflicts create gaps that stop-losses cannot fully protect against.

NAS100 on a forex platform: not actually forex

Many retail platforms list stock-index products alongside currency pairs, so "NAS100 forex" trading has become a common phrase. NAS100 is usually a provider's label for a CFD tracking the Nasdaq-100 index. It sits on the same screen as EUR/USD, but it is an equity-index product with different drivers, different hours and a lower retail leverage cap in the UK and EU (20:1 for major indices).

Illustration: if an index CFD pays $1 per point and the index stands at 20,000, one contract has a notional value of $20,000. At 20:1 the margin is $1,000, and a 1.5% move of 300 points is a $300 gain or loss, nearly a third of that margin. Index products often move more in a day than major currency pairs do, so treat them as a separate market, not a forex variant.

Mistakes that cost beginners the most

Most early losses in forex come from a short list of habits rather than from bad luck. Recognising them in advance is cheaper than learning them with real money.

• Sizing by the margin, not the risk. The platform lets you open whatever your margin allows. That figure has nothing to do with how much you can afford to lose. Size from the stop-loss distance instead.
• Trading without a stop. A position with no exit plan relies on hope. Even a wide stop is better than none, because it forces you to decide the maximum loss before emotion takes over.
• Moving the stop further away. Widening a stop because the price is approaching it turns a planned small loss into an unplanned large one.
• Ignoring the calendar. Holding a leveraged position through a central bank decision or a major data release without realising it was scheduled.
• Counting only the spread. Overnight financing and commissions are small per trade but add up over dozens of trades and weeks of holding.
• Chasing losses. Doubling the size of the next trade to win back the last one is how a bad day becomes a closed account.

None of these requires a better strategy to fix. They require a written plan for each trade: entry, stop, size, target and the reason for the trade, decided before the order is placed.

Where the platform fits in

The trading software (for example MetaTrader 5, covered in our MT5 demo account guide) only displays prices and sends orders. The company behind it decides your prices, holds your money and, in a market-maker model, may take the other side of your trade. That is why checking the firm on a regulator's register comes before comparing charts or features. Our checklist on how to choose a broker walks through it.
