Forex Trading Guide for Beginners

This entry explains how forex trading works from the ground up, for readers who may know crypto but have never looked at a currency chart. Forex, short for foreign exchange, is the market where one currency is swapped for another. It is enormous, it is open five days a week around the clock, and for retail traders it is almost always accessed through a broker using borrowed money. Each of those facts shapes the way the market behaves.

How forex trading works: reading the quote

Currencies are always priced in pairs. In GBP/USD 1.2640, the first currency (pounds) is the base and the second (dollars) is the quote. The number tells you that one pound costs 1.2640 dollars.

• If you buy GBP/USD, you are buying pounds and paying in dollars. You gain if the pound strengthens against the dollar.
• If you sell GBP/USD, you are doing the reverse, and you gain if the pound weakens.

If you already trade BTC/USDT, the logic is identical: base first, quote second. The difference is the size of the moves and the fact that both sides of a currency pair are official money backed by a central bank.

A broker shows two prices at once. The lower one, the bid, is what you receive when you sell; the higher one, the ask, is what you pay when you buy. The gap between them is the spread, and it is the first cost of every trade.

Majors, crosses and exotics

The majors are the most heavily traded pairs, each involving the US dollar: EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD and NZD/USD. Crosses leave the dollar out, for example EUR/GBP or AUD/JPY. Exotics pair a major currency with one from a smaller or emerging economy. Spreads usually widen as you move from majors to exotics, and retail leverage limits are lower for anything outside the majors.

Pips, lots and what a move is worth

Currency prices usually move by fractions of a percent a day, so they are quoted to four or five decimal places. The standard step is the pip: 0.0001 on most pairs and 0.01 on pairs quoted in Japanese yen. Many brokers show a fifth decimal, a tenth of a pip, often called a pipette.

Position size is measured in lots:

When the dollar is the base currency, as in USD/JPY, the pip is worth a fixed amount of yen and has to be converted back into dollars at the current rate, so its dollar value drifts slightly as the price changes. The pip value calculator handles the conversion for you.

Leverage and margin

A standard lot of GBP/USD at 1.2640 controls a position worth $126,400. Few retail traders put that much cash down. Instead the broker asks for margin, a deposit that is a fraction of the position's value, and lends the rest. The ratio is the leverage.

Leverage is capped for retail clients in many places. In the UK, the EU and Australia the limit on major pairs is 30:1, falling to 20:1 on other pairs and gold. In the US, retail forex is capped at 50:1 on majors and 20:1 on others. If losses shrink your margin level to 50% of the required margin in the UK or EU, the broker starts closing positions automatically, and retail CFD clients there have negative balance protection, so an account cannot go below zero.

The cap limits the size of position you can open, not the speed at which you can lose money on it. The margin calculator shows what a given trade ties up, and the position size calculator works back from the amount you are willing to lose.

Sessions and the weekly clock

Forex has no central exchange, so it follows the working day around the world. Trading opens on Sunday at 17:00 New York time, as Wellington and Sydney start their Monday, and runs continuously until 17:00 New York time on Friday. Liquidity moves west through the day: Asia, then Europe, then North America.

• Asian hours are usually calmer, with yen and Australian dollar pairs most active.
• London hours carry the heaviest volume of the day.
• The London and New York overlap is typically the busiest window, with the tightest spreads on majors.

At 17:00 New York time each day, open positions roll over to the next value date and are charged or credited overnight financing. Because spot trades settle two business days forward, most providers apply three days of financing on Wednesday night to cover the weekend. Spreads also tend to widen for a few minutes around the rollover.

What moves exchange rates

An exchange rate is a comparison between two economies, so anything that changes the outlook for one against the other can move it.

• Interest rates. Central banks set short-term rates. Money tends to flow towards currencies where rates are expected to rise, because holding them pays more.
• Inflation and jobs data. These shape what central banks will do next, which is why a monthly employment report can move the dollar within seconds.
• Growth and trade. A strong economy and healthy exports usually support a currency.
• Risk appetite. In stressful periods money often shelters in the US dollar, the Swiss franc and the yen, the same moments when riskier assets, crypto included, tend to fall.

Reading these drivers is the core of fundamental analysis. Many traders also study price charts, but even they usually check the economic calendar so they are not caught holding a position through a major release.

Where your forex funds sit

Before any of the above matters, you have to decide who will hold your money. With a broker authorised in a strict jurisdiction, client forex funds must be kept in segregated accounts, separate from the firm's own cash, so that creditors cannot claim them if the broker fails. Some countries add a compensation scheme on top, up to a limit.

With an unregulated offshore firm, there may be no segregation, no compensation and no authority to complain to. That is why the ten-point broker checklist starts with the regulator's register rather than the spread. And if a stranger offers to trade your money for you in a "managed forex fund" with a promised monthly return, read the scams entry before replying.

What a trade costs

• Spread: paid on every trade, built into the prices you see.
• Commission: charged per lot on some accounts, usually those with very tight spreads.
• Overnight financing (swap): a charge or credit for holding a leveraged position past the daily rollover, based on the interest rate gap between the two currencies plus the broker's markup.
• Conversion: if your account is in a different currency from the profit or loss, a conversion fee may apply.

The trading fees entry adds these up for a real-looking example.

A full worked trade

All figures are illustrative. Suppose you buy 0.3 lots of GBP/USD at 1.2640, which is 30,000 pounds, on an account with 30:1 leverage.

1. Margin: 30,000 × 1.2640 ÷ 30 = $1,264 is set aside.
2. Pip value: 0.3 × 100,000 × 0.0001 = $3 per pip.
3. Stop-loss at 1.2605: that is 35 pips below the entry, so the planned loss is 35 × $3 = $105, plus costs.
4. Target at 1.2710: 70 pips above the entry, worth 70 × $3 = $210 before costs.

Notice what the leverage did: a price change of well under 1% produces a gain or loss that is a sizeable fraction of the $1,264 margin. That is the whole appeal of forex and the whole danger of it. A trader who sets the stop first and sizes the position from it controls the loss; one who picks a size first and hopes for the best does not.
