Forex Trading Guide for Beginners

This guide shows how forex trading works in practice, using one example trade that we follow from quote to closing. Forex, short for foreign exchange, is the buying of one currency with another. Businesses and banks do it to pay for goods and manage risk; retail traders do it to speculate on the exchange rate. The retail version is usually a leveraged contract with a provider rather than a delivery of actual banknotes, and that detail shapes most of the rules below.

Reading a quote

A quote such as GBP/USD 1.2640 / 1.2642 contains three facts. The first currency, GBP, is the base; the second, USD, is the quote currency. The left price (bid) is what the provider pays if you sell one pound; the right price (ask) is what you pay to buy one. The difference, 0.0002, is the spread: 2 pips that you pay the moment you open the trade.

Pips, lots and what one move is worth

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

For pairs that are not quoted in dollars, the pip value has to be converted at the current rate; the pip calculator does that for you.

A worked trade from open to close

Illustrative example You expect the pound to rise against the dollar and buy 0.5 lots (50,000 pounds) of GBP/USD at 1.2640.

• Pip value: 0.5 lots × $10 = $5 per pip.
• Stop-loss at 1.2600: 40 pips below entry, so the planned maximum loss is 40 × $5 = $200, plus costs.
• Target at 1.2720: 80 pips above entry, worth 80 × $5 = $400 before costs.
• Position value: 50,000 × 1.2640 = $63,200.
• Margin at 30:1: $63,200 ÷ 30 = $2,106.67 set aside while the trade is open.
• Spread cost if the spread is 1.2 pips: 1.2 × $5 = $6.

Notice that the reward is twice the risk, but that says nothing about probability. The trade may hit the stop first. The position size calculator works this the other way round: start from the dollar amount you are willing to lose and it tells you the lot size.

How forex trading works behind the platform

When you press buy on a retail platform, you are rarely buying currency on an exchange. In most countries the product is a rolling spot contract or a CFD: an agreement with your provider that pays out the change in the exchange rate. The provider either takes the other side of your trade itself, passes it on to banks and other liquidity providers, or does a mix of both depending on size. Your order ticket usually offers three instructions:

• Market order: fill now at the best available price.
• Limit order: fill only at your chosen price or better, for example buying GBP/USD only if it dips to 1.2620.
• Stop order: becomes a market order once a level is touched; a stop-loss is the most common use.

Every position also has a running profit or loss marked to the current bid (for buys) or ask (for sells). That is why a new trade usually starts slightly negative: you bought at the ask, and it is valued at the bid.

Leverage and margin rules

Retail leverage is capped in the major regulated markets. In the UK and EU, the limits are 30:1 on major pairs and 20:1 on other pairs, gold and major indices. Australia applies similar caps, and in the US the limits are 50:1 on majors and 20:1 on other pairs. If your account equity falls to 50% of the margin required, a UK or EU provider must start closing positions, and negative balance protection means a retail client cannot lose more than the money in the account.

The best time to trade forex

The market opens on Sunday at 17:00 New York time and runs continuously until Friday at 17:00. Activity rises and falls as the main financial centres open and close. For most beginners the best time to trade forex is when the pair you are watching has the most participants, because spreads are usually narrower and prices move more smoothly.

Scheduled data releases, such as central bank decisions and employment figures, can widen spreads for a few minutes even in busy hours. Many beginners simply avoid opening trades just before them.

Overnight financing and the Wednesday triple charge

Positions still open at 17:00 New York time are rolled to the next value date, and the provider charges or credits a financing amount based on the interest-rate difference between the two currencies plus its own mark-up. Because most spot trades settle two business days later, the rollover on Wednesday usually covers the weekend and is charged three times. Our trading fees guide shows how these charges add up over a week.

What moves exchange rates

• Interest rate expectations. A central bank that is expected to keep rates higher for longer tends to support its currency.
• Inflation and jobs data, because they change those expectations.
• Trade and capital flows, such as large companies converting overseas earnings.
• Risk appetite. In stressed markets, money often moves towards currencies seen as safe.

None of these produces a reliable forecast. They explain why prices move, not where they will go next.

A short routine before every trade

1. Write down why you are entering and what would prove the idea wrong.
2. Place the stop-loss at that level, then size the position so that hitting it costs no more than your chosen share of the account.
3. Check the economic calendar for scheduled releases in the next few hours.
4. Check the spread and the overnight financing rate if you might hold past 17:00 New York time.
5. After closing, record the result and whether you followed the plan. Over time the log teaches more than any single trade.
