Risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. The majority of retail investor accounts lose money when trading CFDs. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

Forex has its own language, and brokers rarely stop to explain it. This glossary defines the 45 terms new EU retail traders meet most often — in plain English, with the EU-specific context (ESMA leverage caps, MiFID II disclosures, negative balance protection) that most generic glossaries leave out.

Use the search box to jump straight to a term, or browse by category. Each definition is short on purpose: enough to understand what you are reading in a broker's fee table or platform, not a textbook.

The basics

Forex (FX)Basics

Short for "foreign exchange" — the global market where currencies are traded against each other. Most retail EU traders access it through CFDs rather than owning the underlying currency.

Currency pairBasics

Two currencies quoted against each other, e.g. EUR/USD. The first is the base currency, the second is the quote currency. A price of 1.0850 means one euro buys 1.0850 US dollars.

Majors, minors, exoticsBasics

Majors are the most-traded pairs (all involve USD, e.g. EUR/USD, GBP/USD). Minors (crosses) exclude USD, e.g. EUR/GBP. Exotics pair a major with an emerging-market currency and usually carry the widest spreads.

PipBasics

The smallest standard price move in most pairs — the fourth decimal place (0.0001). For JPY pairs it is the second decimal (0.01). Pips are how spreads, profits and losses are measured.

PipetteBasics

A fractional pip — one tenth of a pip (the fifth decimal place). Many brokers now quote to pipettes for tighter pricing, so a spread of "0.8" may display as 0.00008.

Lot sizeBasics

The volume of a trade. A standard lot is 100,000 units of the base currency, a mini lot is 10,000, and a micro lot is 1,000. Beginners usually start with micro or mini lots to keep risk small.

Bid and askBasics

The bid is the price you can sell at; the ask (or offer) is the price you can buy at. The ask is always slightly higher — the gap between them is the spread.

Long / shortBasics

Going long means buying, expecting the price to rise. Going short means selling, expecting it to fall. CFDs let you do both without owning the currency.

CFD (contract for difference)Basics

A derivative that tracks a currency pair's price without you owning it. You profit or lose on the price difference. Nearly all retail forex trading in the EU is done via CFDs and is covered by ESMA's retail protection rules.

Account currencyBasics

The currency your trading account is denominated in (often EUR for EU traders). If you trade a pair that does not include your account currency, a conversion fee may apply — a common hidden cost.

Costs & pricing

SpreadCosts

The difference between the bid and ask price, measured in pips — the broker's built-in charge on every trade. Tighter is cheaper. See our full guide to how forex spreads work.

Fixed vs variable spreadCosts

A fixed spread stays the same regardless of market conditions; a variable (floating) spread widens and narrows with liquidity. We compare the trade-offs in fixed vs variable spreads for EU traders.

CommissionCosts

A separate per-trade charge, common on raw-spread and ECN accounts (e.g. €3.50 per lot per side). It replaces part of the spread markup. Always read whether it is charged per side or round-turn.

Swap (rollover)Costs

An interest charge or credit for holding a position overnight, based on the interest-rate difference between the two currencies. It can quietly erode profits on multi-day trades — see swaps and overnight fees explained.

ECN / STPCosts

Order-routing models. ECN (Electronic Communication Network) and STP (Straight Through Processing) pass your order to liquidity providers with raw spreads plus a commission. We list the best ECN forex brokers for EU traders.

Market maker vs dealing deskCosts

A market maker sets its own prices and may take the other side of your trade; a dealing desk manages order flow internally. Both are legal under EU regulation, but the pricing model affects your all-in cost.

Inactivity feeCosts

A monthly charge (typically €10–€50) applied after 3–12 months without trading. One of the most common hidden costs — see how to spot hidden forex fees.

Deposit / withdrawal feeCosts

Charges for moving money in or out. Many EU brokers advertise "free deposits" but apply withdrawal fees or currency-conversion markups. Check both directions before funding.

All-in costCosts

The true cost of a trade: spread + commission + any swap. Comparing brokers on spread alone is misleading — always add commission back in. Our trade cost calculator does the maths.

Orders & execution

Market orderOrders

An instruction to buy or sell immediately at the best available price. Fast, but the fill price can differ slightly from what you saw — see slippage.

Limit orderOrders

An order to buy below or sell above the current price, filled only if the market reaches your level. Used to enter at a better price or take profit.

Stop-lossOrders

An order that closes a losing position automatically at a set price, capping your loss. The single most important risk tool for beginners — always set one.

Take-profitOrders

An order that closes a winning position automatically at a target price, locking in gains without you watching the screen.

SlippageOrders

The difference between the price you expected and the price you actually got, usually during fast markets or news. Can work for or against you.

RequoteOrders

When a broker cannot fill your order at the requested price and offers a new one. More common with dealing-desk brokers; rare with ECN execution.

Execution speedOrders

How quickly your order is filled after you click. Faster execution reduces slippage. We track this in our EU broker execution scorecard.

Spread wideningOrders

A temporary jump in the spread during low liquidity or major news. A "0.6 pip" advertised spread can briefly become several pips at these moments.

Risk & margin

LeverageRisk

Trading a position larger than your deposit. Expressed as a ratio (e.g. 30:1). For EU retail traders, ESMA caps major-pair leverage at 30:1 — see our ESMA leverage analysis.

MarginRisk

The deposit required to open a leveraged position. At 30:1 leverage, a €10,000 position needs about €333 of margin. It is set aside, not spent.

Free vs used marginRisk

Used margin is locked in your open trades; free margin is what remains available to open new positions or absorb losses.

Margin callRisk

A warning that your account equity has fallen too close to the margin needed to keep positions open. You must add funds or close trades.

Margin close-out (stop-out)Risk

Under ESMA rules, EU brokers must automatically close retail positions when account equity falls to 50% of required margin — a safety floor to limit losses.

Negative balance protectionRisk

Mandatory for EU retail traders: you cannot lose more than the money in your account, even in a violent market gap. It does not, however, protect you from fees.

DrawdownRisk

The drop from a peak in your account balance to a subsequent low, usually shown as a percentage. A measure of how much risk a strategy has taken.

Equity vs balanceRisk

Balance is your account value with all trades closed; equity is balance plus or minus the running profit/loss of open trades. Margin is measured against equity.

VolatilityRisk

How much and how fast a price moves. Higher volatility means bigger opportunities and bigger risks — and often wider spreads.

Risk-to-reward ratioRisk

The size of your potential loss versus your target gain on a trade, e.g. 1:2 means risking €50 to make €100. A core discipline for consistent trading.

Regulation & account terms

ESMARegulation

The European Securities and Markets Authority, which sets the retail-trading rules EU brokers follow: leverage caps, negative balance protection, standardised risk warnings and a ban on trading bonuses.

MiFID IIRegulation

The EU directive governing investment services. It requires brokers to disclose all costs and charges up front in a Key Information Document before you open an account.

CySECRegulation

The Cyprus Securities and Exchange Commission — one of the most common EU regulators for forex brokers. A CySEC licence lets a broker "passport" its services across the EU.

Regulated / licensedRegulation

A broker authorised by an EU regulator (CySEC, BaFin, CNMV and others). Always check the licence number on the regulator's public register. See our forex broker regulation guide.

Segregated fundsRegulation

Client money kept in separate bank accounts from the broker's own funds, so it is protected if the broker fails. A basic requirement for EU-regulated brokers.

Investor compensation schemeRegulation

An EU safety net (e.g. the Cyprus ICF) that reimburses eligible clients up to a set limit — commonly €20,000 — if a regulated broker becomes insolvent.

KID (Key Information Document)Regulation

A standardised cost-and-risk disclosure EU brokers must give you before you trade a CFD. It contains the fee numbers worth reading before you deposit.

Demo accountRegulation

A practice account with virtual money and live prices. The safest way to learn a platform — though some demos understate swap and slippage costs.

Retail vs professional clientRegulation

Retail clients get full ESMA protections (leverage caps, negative balance protection). Professional clients waive some protections for higher leverage — rarely suitable for beginners.

Frequently asked questions

What is the most important forex term for a beginner to understand?

Leverage. It is what makes forex both attractive and dangerous. Understanding that 30:1 leverage multiplies losses as fast as gains — and that ESMA caps it at 30:1 for EU retail traders precisely for that reason — is the foundation of trading safely.

What is the difference between a pip and a spread?

A pip is a unit of price movement (0.0001 on most pairs). A spread is a distance measured in pips — specifically the gap between the bid and ask price, which is the broker's charge on the trade. So the spread is quoted in pips.

Do these terms mean the same thing worldwide?

The core terms (pip, lot, spread, leverage) are universal. What changes by region is the regulation: leverage caps, negative balance protection and the compensation scheme described here are specific to EU-regulated retail accounts under ESMA and MiFID II.

Where can I check that a broker is properly regulated?

On the public register of the regulator named on the broker's website — for example the CySEC register in Cyprus or BaFin in Germany. Match the licence number exactly. Our regulation guide walks through the steps.

Risk warning: Trading forex and CFDs carries a high risk of loss. Leverage amplifies both gains and losses. Past performance is not a reliable indicator of future results.
