Forex Trading Guide for Beginners

How forex trading works comes down to one idea: you exchange one currency for another, hoping the rate moves in your favour before you exchange back. Retail traders almost never take delivery of the money. They hold a leveraged position with a broker and settle the difference in cash. This guide builds that picture from the quote upwards.

Reading a currency quote

A pair such as AUD/USD 0.6600 tells you that one Australian dollar costs 0.66 US dollars. The first currency is the base; the second is the quote. If you think the Australian dollar will strengthen against the US dollar, you buy the pair. If you think it will weaken, you sell it.

Every quote has two sides. The bid is the price at which you can sell; the ask (or offer) is the price at which you can buy. The gap is the spread, and it is the first cost of every trade. If AUD/USD is quoted 0.6599 / 0.6601, the spread is two pips and you start every position slightly behind.

Pips, lots and what a move is worth

Currencies move in small steps. The standard unit is the pip: 0.0001 for most pairs and 0.01 for pairs that include the Japanese yen. Many brokers also quote a fifth decimal, sometimes called a pipette.

Position size is measured in lots:

For pairs where the US dollar is not the quote currency, the pip value has to be converted, which is what our pip calculator does automatically.

Leverage and margin

Because daily moves in major pairs are small, forex is usually traded with borrowed exposure. Your broker asks you to put up a fraction of the position's value as margin. With 30:1 leverage, the margin is one thirtieth of the position's value.

Rules matter here. In the UK, the EU and Australia, retail clients are limited to 30:1 on major pairs and 20:1 on the others. In the US, the limits are 50:1 on majors and 20:1 elsewhere. If your equity falls to half the margin required, UK and EU brokers must start closing positions, and retail clients there are protected against losing more than their account balance. Offshore brokers advertising 500:1 or more are, by definition, operating outside those rules.

How forex trading works in one worked trade

The numbers below are illustrative and ignore slippage.

1. You buy 0.3 lots of AUD/USD at 0.6600. That is 30,000 Australian dollars, worth $19,800.
2. At 30:1 leverage, the broker sets aside $19,800 ÷ 30 = $660 as margin.
3. Each pip on 30,000 units is worth 30,000 × 0.0001 = $3.
4. The spread is 1.2 pips, so the trade opens $3.60 in the red.
5. You set a stop-loss at 0.6570, 30 pips away. If it is hit, the loss is 30 × $3 = $90 plus costs.
6. You set a target at 0.6660, 60 pips away. If it is reached, the gain is 60 × $3 = $180 before costs.

Notice that the $90 risk is already about 14% of the $660 margin. That is the effect of leverage. Use the position size calculator to reverse the process: start from the loss you can accept and let it tell you the lot size.

Order types you will meet

• Market order: fills straight away at the best price the broker offers. In quiet markets that is close to the price you saw; around news it may not be.
• Limit order: waits until the price reaches a level you choose, or better. Useful for entering at a planned price.
• Stop order: triggers a market order once a price is touched. A stop-loss is the defensive version.
• Take-profit: a limit order that closes a winning position at a target.

A stop-loss is a plan, not a promise. If the market jumps over your level, for example at the Sunday open after weekend news, the order fills at the next available price, which can be well beyond it. Some brokers sell guaranteed stops for an extra charge.

Trading sessions and liquidity

The market opens on Sunday at 17:00 New York time, as Wellington and Sydney begin their Monday, and runs continuously until Friday at 17:00 New York time. Activity moves with the sun:

• Asia-Pacific: Sydney and Tokyo. Yen and Australian dollar pairs are most active.
• Europe: London is the largest single centre for currency dealing. Euro, sterling and Swiss franc pairs pick up.
• North America: New York. US data releases land during this session.

Spreads tend to be tightest when two major centres overlap, especially London and New York, and widest around 17:00 New York time when the trading day rolls over. Positions held past that cut-off are charged or paid a financing amount called a swap, and many brokers apply three days' worth on Wednesday to cover the weekend.

What moves exchange rates

• Interest rate expectations. Central bank decisions, and what markets expect them to do next, are the single largest driver of major pairs.
• Economic releases. Inflation, employment and growth figures arrive on a published calendar and can move a pair sharply within seconds.
• Risk appetite. In stressed markets money often flows towards the US dollar, the yen and the Swiss franc, and away from currencies linked to commodities.
• Trade and capital flows. Over longer periods, what a country buys, sells and borrows from abroad shapes its currency.

Two further ideas are worth knowing. The carry trade means borrowing in a low-interest currency to hold a higher-yielding one, collecting the difference through positive swaps; it works until a sharp move in the exchange rate wipes out months of interest in days. And correlation means some pairs tend to move together, such as those sharing the US dollar, so holding several of them can quietly multiply the same bet.

Crypto readers will recognise the pattern: the same risk-off days that pull bitcoin lower often push the dollar and yen higher.

Costs, including "commission-free" accounts

There is no such thing as free forex trading. A "commission-free" account builds its charge into a wider spread; a "raw spread" account shows a narrower spread and adds a commission per lot. Add overnight swaps, and currency conversion if your account is not in dollars. Commission-free forex can end up the more expensive choice for active traders. Our breakdown of trading fees runs the numbers.

Mistakes beginners make most

1. Sizing by feel. Choosing one lot because it is a round number, instead of working out what the stop-loss would cost.
2. Moving the stop. Pushing a stop further away when price approaches it turns a planned small loss into an unplanned large one.
3. Trading through news. Spreads can widen sharply in the seconds around a central bank decision or a jobs report.
4. Ignoring the swap. A position held for weeks can pay more in financing than it ever made in price movement.
5. Using a demo account for too short a time. A few good days on virtual money prove very little. Practise until you have seen losing weeks as well as winning ones.

Where forex and crypto meet

Some providers now offer crypto pairs alongside currencies, usually as CFDs. In the UK these crypto derivatives cannot be sold to retail consumers at all, and in the EU they carry the lowest leverage cap of 2:1. If a platform offers you high-leverage crypto CFDs, check who regulates it using the steps in how to choose a broker.
