The foreign exchange market — commonly known as forex or FX — is the largest and most liquid financial market in the world. With daily turnover exceeding seven trillion US dollars, it dwarfs every equity and commodity exchange combined. Yet despite its scale, the fundamentals of forex trading can be understood in a single sitting.
At its core, forex trading is the simultaneous buying of one currency and selling of another. Every trade is a bet on how the relative value of two currencies will move. If you think the euro will strengthen against the US dollar, you buy EUR/USD. If you think it will weaken, you sell EUR/USD. That is the entire mechanic — every other concept builds on it.
How Currency Pairs Work
Every forex price is quoted as a pair of two currency codes separated by a slash. The first code is called the base currency; the second is the quote currency. The price tells you how much of the quote currency is needed to buy one unit of the base currency.
For example, if EUR/USD is quoted at 1.08500, it means one euro costs 1.08500 US dollars. When that price rises to 1.09000, the euro has strengthened — or equivalently, the dollar has weakened — by 500 pips.
A pip (point in percentage) is the smallest standard price move in a forex quote. For most pairs, it equals the fourth decimal place (0.0001). For JPY pairs, it equals the second decimal place (0.01). Pips are how traders measure profit, loss, and market volatility.
Major, Minor, and Exotic Pairs
- Major pairs include the US dollar paired with another highly traded currency: EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD, USD/CAD, NZD/USD. These have the tightest spreads and deepest liquidity.
- Minor pairs (also called cross pairs) exclude the US dollar but include other major currencies: EUR/GBP, EUR/JPY, GBP/JPY, AUD/NZD, EUR/CHF.
- Exotic pairs match a major currency against the currency of a smaller or emerging economy. They typically show wider spreads and sharper movements.
Lots, Leverage, and Margin
A lot is the standard unit of size in forex trading. One standard lot equals 100,000 units of the base currency. A mini lot is 10,000 units and a micro lot is 1,000 units. Choosing an appropriate lot size is one of the most important risk-management decisions you will make.
Leverage lets you control a position much larger than the capital you put up. At 1:100 leverage, 1,000 US dollars of margin controls 100,000 US dollars of currency. Leverage amplifies gains — but also losses — in direct proportion, so it must be used with discipline.
A 1% adverse move at 1:100 leverage wipes out 100% of your deposited margin on that position. Always size your trades so you can survive a string of losses without closing your account.
When the Forex Market is Open
Forex trades 24 hours a day from Sunday evening to Friday evening (UTC). Activity rotates across four major sessions: Sydney, Tokyo, London, and New York. The overlap between London and New York (approximately 12:00–16:00 UTC) generates the highest volume and tightest spreads of the trading week.
Reading a Forex Quote
Every live quote shows two numbers: the bid (the price at which your broker will buy the base currency from you) and the ask (the price at which they will sell it to you). The gap between them is the spread, and it is effectively the cost of entering a trade. Tighter spreads mean lower round-trip costs.
“In any market, your edge begins the moment you stop guessing and start understanding how prices are formed.”
Key Takeaways
- Forex is a two-sided market — every trade is long one currency and short another.
- Prices move in pips, and profit/loss is the product of pips moved and position size.
- Leverage magnifies both directions; treat it as risk, not opportunity.
- Liquidity peaks during the London–New York session overlap.
- Start with major pairs and small lot sizes while you learn.
