Forex has its own vocabulary, and nothing slows a beginner down more than hitting five unfamiliar words in one sentence. This is your quick-reference glossary: the 20 terms that unlock almost every other forex guide, each explained in plain English.
The essentials
- Currency pair — Two currencies quoted together, like EUR/USD. You're always buying one and selling the other.
- Base currency — The first currency in a pair (the EUR in EUR/USD); the one you're buying or selling.
- Quote currency — The second currency (the USD in EUR/USD); the price is expressed in it.
- Pip — The smallest standard price move in a pair, usually the fourth decimal place.
- Spread — The gap between the bid and ask price — a core cost of every trade.
Prices and orders
- Bid — The price at which you can sell.
- Ask — The price at which you can buy.
- Lot — A standardised trade size. A standard lot is 100,000 units; mini and micro lots are smaller.
- Long — Buying, expecting price to rise.
- Short — Selling first, expecting price to fall.
Risk and money
- Leverage — Controlling a large position with a small deposit; it magnifies gains and losses.
- Margin — The deposit required to open a leveraged position.
- Margin call — A demand to add funds (or close trades) when losses eat into your margin.
- Stop loss — An order that closes a trade automatically to cap a loss.
- Take profit — An order that closes a trade automatically to lock in a gain.
Conditions and costs
- Volatility — How much and how fast price moves.
- Liquidity — How easily you can buy or sell without moving the price.
- Swap (rollover) — Interest paid or earned for holding a position overnight.
- Slippage — When an order fills at a different price than expected, common around news.
- OTC (over-the-counter) — Trading directly with a dealer rather than on a central exchange, as most retail forex does.
Warning
Two terms cause the most beginner damage: leverage and margin. They sound technical, but together they're the fastest way to lose an account. Understand them before you fund anything.
How to use this list
You don't need to memorise all 20 at once. Bookmark this page and refer back whenever a term trips you up. The vocabulary sinks in naturally as you read more guides and watch real charts.
Risk
Knowing the words isn't the same as knowing the risks. Even with the vocabulary down, trade only with money you can afford to lose and always use a stop loss.
Put the terms into practice
Vocabulary becomes second nature when you see it in action. A regulated broker with a free demo lets you connect each term to a live chart before risking real money.
