What Are the Major Currency Pairs?

Here is a number that catches most new traders off guard: the US dollar is on one side of close to 90% of all forex trades. Not 90% of American trades. Close to 90% of every currency trade on the planet, including a Japanese bank dealing with a German fund.

That sounds impossible until you remember every forex trade involves two currencies. Add up the share of every currency and the total comes to 200%, not 100%. The dollar takes a huge slice of it because most oil, most commodities and a large share of international invoices are still priced in dollars.

This is the entire reason the majors exist. A major currency pair is a pair where one side is the US dollar and the other side is the currency of another large, developed economy. Every other category in forex is defined by how far it sits from that centre.

That concentration has a very practical effect on you. Because so much of the world's trading activity points at the dollar, the pairs containing it have the most orders resting in the market at any given hour of the day. That is precisely what makes them cheaper and steadier to trade than anything else on your platform.

Most brokers and most textbooks list seven majors. There is no official committee voting on the membership, so you will occasionally see a list of six or eight, but these seven appear on almost every one. The spreads below are typical retail ranges during normal market hours, not a promise from any particular broker.

Reading a pair is simpler than it looks. In EUR/USD, the euro is the base currency and the dollar is the quote currency. A price of 1.0850 means one euro costs 1.0850 US dollars. The currencies involved across the seven are the euro (EUR), the Japanese yen (JPY), the British pound (GBP), the Swiss franc (CHF), the Australian dollar (AUD), the Canadian dollar (CAD) and the New Zealand dollar (NZD).

The nicknames are not marketing inventions. GBP/USD is called Cable because pound and dollar quotes used to travel down a transatlantic telegraph cable laid on the seabed in the 1860s. USD/CAD is the Loonie, after the loon bird stamped on the Canadian one dollar coin. EUR/USD picked up Fiber much later, a nod to the fibre optic lines that eventually replaced all that copper.

Take the dollar out of a pair but keep two major currencies, and you get a minor pair, also called a cross. EUR/GBP, EUR/JPY, AUD/NZD and CAD/CHF all qualify. The name is a leftover from the days when turning pounds into yen meant crossing through the dollar in two separate trades.

Pair a major currency with the currency of a smaller or emerging economy and you get an exotic. USD/TRY (Turkish lira), USD/ZAR (South African rand), USD/MXN (Mexican peso) and EUR/PLN (Polish zloty) all live here. Nothing is wrong with those economies. The question is purely how many people are trading their currency at 3am on a Tuesday.

That is the real dividing line, and it has a name: liquidity. Liquidity means how many buyers and sellers are standing ready to trade at any given moment. High liquidity gives you a tighter spread, faster fills and prices that move in small, orderly steps. Low liquidity gives you the opposite, and it charges you for the privilege.

Your MetaTrader 5 platform has already sorted this out for you. Right click inside the Market Watch window, choose Symbols, and you will see your broker's folders: Forex Majors, Forex Minors, Forex Exotics. If a pair is buried three folders deep and has to be enabled before it will even show you a price, that tells you plenty about how many people trade it.

Your broker quotes two prices for every pair. The bid is what you can sell at, the ask is what you can buy at, and the gap between them is the spread. That gap is the first cost of every trade, and you pay it the instant you open a position.

Say EUR/USD is quoted 1.08500 bid and 1.08508 ask. The difference is 0.00008. On most pairs one pip is 0.0001 (on yen pairs it is 0.01), so that spread is 0.8 pips.

Now put a size on it. A 0.10 lot trade on EUR/USD is 10,000 euros. One pip on 10,000 units is 10,000 x 0.0001 = $1. So the spread costs you 0.8 x $1 = $0.80 the moment you click buy. Open and close that same trade 20 times in a month and the spread has quietly taken 20 x $0.80 = $16 from your account.

Some accounts advertise a near zero spread and charge a separate commission instead, commonly around $7 per standard lot for a round turn, which works out to roughly $0.70 on a 0.10 lot trade. Different packaging, similar total. The point is that on the majors this cost is small and predictable.

Break even is further away than you think

With a 0.8 pip spread on EUR/USD, price only has to move 0.8 pips your way before you are level. On a quiet exotic quoted with a 45 pip spread, it has to move 45 pips, more than fifty times further, just to get you back to zero.

Exotics move. A pair like USD/TRY or USD/ZAR can travel several percent in a single session while EUR/USD often moves less than 1%. On a chart, that looks like pure opportunity sitting there unclaimed.

The catch arrives in three parts. The spread is wider, so every trade starts deeper in the hole. Liquidity thins out fast around news, so your stop loss can fill at a worse price than you asked for, which is called slippage. And overnight financing (the swap your broker charges or pays for holding a position past the daily rollover) is usually much larger on exotics, because the interest rate gap between the two currencies is much larger.

There is a quieter problem too. Fewer participants means fewer analysts covering the currency, patchier economic data, and in some cases a central bank that steps into the market without warning. When price moves because of a policy decision nobody outside the country saw coming, no amount of chart reading would have saved you.

None of this makes exotics forbidden. Experienced traders use them on purpose and for good reasons. It does mean a pair that punishes small mistakes harder is a strange place to go and make your first ones.

Gaps do not care about your stop loss

Thin pairs can reopen on Sunday a long way from where they closed on Friday. A stop loss cannot protect you across a gap, because there is no price in between for it to fill at. Your position size is the only real defence.

If you want one answer, it is EUR/USD. It is the most traded pair in the world, which buys you the tightest spreads available anywhere, the smallest slippage, and price that tends to move in steps rather than lurches.

There is a less obvious advantage too. Because so many people trade it, every economic release touching the euro or the dollar gets explained somewhere, in your language, within minutes. When you are still learning why price moved, that matters far more than it sounds.

USD/JPY and GBP/USD are sensible second pairs once EUR/USD feels familiar. GBP/USD typically covers a wider daily range, so the same lot size produces bigger swings in your balance. Crosses like GBP/JPY are famously volatile and are better left until you have a routine you trust. Exotics can wait longer still.

One honest caveat before you go. No pair is safe. EUR/USD is the calmest of the majors and it can still travel 100 pips in an hour after a central bank surprise. Liquidity lowers your transaction costs. It does not lower your risk. That job belongs to your position size and your stop loss, and nothing else.

Try the 30 day rule

Pick one major and trade only that pair for 30 days. You will start recognising its normal daily range, its quiet hours and how it reacts to news. That pattern recognition is worth more than watching eight charts badly.
