CFD risk warning: Between 74% and 89% 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.
Walking into a forex broker's platform for the first time can feel like entering a room where everyone is speaking a different language. Spreads, pips, margin calls, swap rates — these terms appear everywhere, and misunderstanding even one can cost real money.
This guide explains the 40 terms every EU retail trader must know before placing their first trade, with plain-English definitions, worked examples, and EU-specific context (ESMA rules, MiFID II, and CIF regulation numbers where relevant).
1. Market basics
These are the foundation. You will encounter every one of these terms within your first five minutes on a trading platform.
Currency pair
Basics
Two currencies quoted against each other — the base currency (first) and the quote currency (second). EUR/USD shows how many US dollars one euro buys. Major pairs involve USD; minor pairs don't. Exotic pairs include one emerging-market currency.
Example: EUR/USD 1.0850 means €1 = $1.0850
Pip
Basics
The smallest standard price increment. For most 4-decimal-place pairs (EUR/USD, GBP/USD), 1 pip = 0.0001. For JPY pairs (USD/JPY), 1 pip = 0.01. Many brokers also quote fractional pips (pipettes) — a 5th decimal place.
Example: EUR/USD moves from 1.0850 to 1.0855 = 5 pips
Bid price
Basics
The price at which the broker will buy the base currency from you — the price you sell at. Always lower than the ask price. When you click "Sell" on a currency pair, you trade at the bid.
Example: EUR/USD Bid 1.08497
Ask price
Basics
The price at which the broker will sell the base currency to you — the price you buy at. Always higher than the bid. The difference between ask and bid is the spread — your first cost on every trade.
Example: EUR/USD Ask 1.08510
Lot size
Basics
The standardised unit of a forex trade. Standard lot = 100,000 units. Mini lot = 10,000 units. Micro lot = 1,000 units. Nano lot = 100 units. Most EU retail accounts allow micro or mini lots, which is how small accounts control risk.
Example: 0.01 lot on EUR/USD = 1,000 units = ~$0.10/pip value
Base vs quote currency
Basics
In EUR/USD, EUR is the base (the currency you're buying or selling) and USD is the quote (the currency you're using to pay). Profits and losses are usually denominated in the quote currency. If your account is in EUR and you trade EUR/USD, your P&L is in USD and converted back.
Example: Buying EUR/USD = buying euros, selling dollars
Long position
Basics
Buying a currency pair in expectation that it will rise in value. You profit when the pair moves up. "Going long" EUR/USD means you believe the euro will strengthen against the dollar. Forex allows you to be long or short on any pair.
Example: Buy EUR/USD at 1.0850; sell at 1.0900 = +50 pips profit
Short position
Basics
Selling a currency pair in expectation that it will fall. You profit when the pair moves down. Unlike stocks, forex (and CFDs) make short-selling as easy as long-buying — you simply click "Sell" instead of "Buy".
Example: Sell EUR/USD at 1.0850; buy back at 1.0800 = +50 pips profit
2. Costs & fees
Every trade has a cost. Understanding these terms helps you calculate the true cost before you execute.
Spread
Cost
The gap between bid and ask, expressed in pips. This is the broker's primary revenue on Standard accounts. A 1.0-pip spread on EUR/USD means you start each trade down 1 pip. Spreads vary by account type, broker, and market conditions.
Example: Ask 1.08510 − Bid 1.08497 = 1.3-pip spread
Commission
Cost
A flat fee charged per lot traded, typically on ECN/Raw accounts that offer tight raw spreads. Commission is charged on open and/or close of a trade. The total cost = raw spread + commission × 2 (round-turn). Common: $3–$7 per side per standard lot.
Example: $3.50/lot each way = $7 round-turn on 1 standard lot
Swap / rollover
Cost
An overnight fee charged (or credited) when you hold a position past the daily rollover time (usually 22:00 server time). Based on the interest rate differential between the two currencies. Swaps can be positive (you receive money) or negative (you pay). Swap-free accounts replace this with a fixed administration fee.
Example: Holding 1 lot EUR/USD long overnight may cost $0.50–$3.00/night
Pip value
Cost
The monetary value of a 1-pip move for your trade size. Depends on lot size, the currency pair, and your account currency. Knowing pip value lets you calculate risk precisely before placing a trade.
Example: 1 standard lot EUR/USD = $10/pip; 0.10 lot = $1/pip; 0.01 lot = $0.10/pip
Slippage
Cost
The difference between the price you expected to fill at and the price you actually filled at. Occurs during high volatility or low liquidity (e.g. news releases, market open). Can work for or against you. Stop losses may not execute at the exact price in fast markets — this is called gapping.
Example: Order to sell at 1.0850 filled at 1.0843 = 7 pips of negative slippage
Deposit / withdrawal fee
Cost
Fees charged by the broker for depositing or withdrawing funds. Many EU-regulated brokers charge zero deposit fees but may charge for withdrawal via certain methods (e.g. bank wire). Always check the full fee schedule before opening an account.
Example: Free card deposits; €5 for international bank transfer
Inactivity fee
Cost
A monthly charge levied on dormant accounts, typically after 6–12 months of no trading activity. Can erode small balances if forgotten. Check the broker's fee schedule — some EU brokers charge €5–€10/month after the inactivity threshold.
Example: €10/month if no trades placed in 12 months
3. Order types
Orders are your instructions to the platform. The right order type can protect your capital and improve your entry price.
Market order
Orders
An instruction to buy or sell immediately at the current best available price. Guarantees execution but not price — you may get slight slippage. Most beginner trades are market orders. Best used when entering quickly is more important than getting an exact price.
Example: "Buy EUR/USD now at market" fills at 1.08510
Limit order
Orders
An instruction to buy or sell only at a specified price or better. Buy limit orders execute at or below your set price; sell limits execute at or above. Guarantees price but not execution — if the market never reaches your level, the order won't fill.
Example: Buy EUR/USD limit at 1.0820 — only fills if price drops to 1.0820
Stop order
Orders
Triggers a market order when the price reaches a specified level. A buy stop is placed above current price (to enter a breakout); a sell stop is placed below (to enter a breakdown). Can be used to enter or exit trades. Subject to slippage in fast markets.
Example: Buy stop EUR/USD at 1.0900 — triggers a buy if price reaches 1.0900
Stop loss
Orders
An order that automatically closes your position at a pre-set loss level. The most important risk management tool for retail traders. Set it before or immediately after opening a position. Under ESMA rules, EU retail accounts have negative balance protection — but stop losses are still essential to limit losses before hitting that protection.
Example: Buy EUR/USD at 1.0850; stop loss at 1.0820 = maximum loss of 30 pips
Take profit
Orders
An order that automatically closes a profitable position at a target price. Locks in gains without requiring you to watch the screen. Together with a stop loss, defines your risk:reward ratio. A 1:2 risk:reward means your take profit is twice as far from entry as your stop loss.
Example: Buy at 1.0850; TP at 1.0910 = 60-pip profit target (2× the 30-pip SL)
Trailing stop
Orders
A dynamic stop loss that moves in your favour as the trade profits, but never moves against you. Set as a fixed number of pips from the current price. Lets profits run while automatically protecting gains if the market reverses. Can be set in MT4/MT5.
Example: 20-pip trailing stop on a long EUR/USD trade — follows price up, locks in profit
Pending order
Orders
Any order that is not executed immediately — limit, stop, or stop-limit orders. The platform holds the instruction and executes it automatically if the conditions are met. Pending orders expire if not filled by a set time or manually cancelled.
Example: Place a buy limit at 1.0820 valid until end of day
4. Risk & account management
These terms directly affect how much money you can lose. Know them before you fund your account.
Leverage
Risk
The ratio of position size to account balance used. ESMA caps EU retail leverage at 30:1 for major pairs. Leverage amplifies both gains and losses proportionally. A 1% move against a 30:1 position = 30% of your margin lost. High leverage is the primary reason retail traders lose money quickly.
Example: €1,000 at 30:1 controls €30,000 of EUR/USD
Margin
Risk
The deposit required to open and hold a leveraged position. Expressed as a percentage of the full position value. At 30:1, margin requirement = 3.33%. Margin is not a fee — it's collateral held by the broker. It's returned when you close the position (adjusted for P&L).
Example: Opening €10,000 EUR/USD at 3.33% margin requires €333
Free margin
Risk
The amount of margin not currently tied up in open positions. Free margin = equity minus used margin. This is the money available to open new trades or absorb losses on existing ones. When free margin falls to zero, no new trades can be opened.
Example: Account equity €1,500; used margin €333; free margin €1,167
Margin call
Risk
An alert from the broker when your account equity falls below a specified percentage of required margin (often 100%). You must either deposit more funds or close some positions. If equity falls further to the stop-out level (often 50%), the broker begins closing your positions automatically.
Example: Broker margin call at 100% of used margin — deposit or close trades
Negative balance protection
Risk
An ESMA-mandated EU rule: your losses on a retail CFD/forex account can never exceed your deposited funds. If extreme market volatility causes your account to go into deficit, the broker absorbs the loss. Only applies to retail clients — Professional clients do not have this protection.
Example: Account value drops to −€200 due to gap; broker resets it to €0
Equity
Risk
Your account balance adjusted for unrealised profits and losses on open positions. Equity = balance + open P&L. This is the real-time value of your account. It changes every second while you have open trades. A margin call triggers based on equity, not balance.
Example: Balance €1,000; open trade down €120; equity = €880
Risk:reward ratio
Risk
The ratio of potential loss (stop loss distance) to potential gain (take profit distance) on a trade. A 1:2 ratio means you risk 1 pip to make 2. Professional traders typically trade only when the risk:reward is at least 1:2. Even with a 40% win rate, a 1:2 R:R strategy is profitable overall.
Example: SL = 20 pips; TP = 40 pips = 1:2 risk:reward
Drawdown
Risk
The peak-to-trough decline in your account balance over a period. A 20% drawdown means your account fell 20% from its highest point. Drawdown measures how much pain a trading strategy inflicts before recovering. Prop firms and fund managers monitor maximum drawdown as a key risk metric.
Example: Account peaks at €2,000, falls to €1,500 = 25% drawdown
5. Account & platform terms
MetaTrader 4 / MT4
Platform
The world's most popular retail forex trading platform. Available as desktop, web, and mobile apps. Most EU brokers support MT4. Supports custom indicators (EAs), backtesting, one-click trading. Being gradually replaced by MT5 but still widely used as of 2026.
Used by: Exness, AvaTrade, IC Markets, XM, Pepperstone
MetaTrader 5 / MT5
Platform
The successor to MT4, offering more timeframes, order types, and multi-asset trading (stocks, futures). MT5 EAs are not backwards-compatible with MT4. Most major EU brokers now offer MT5 alongside or instead of MT4. Features: depth of market, economic calendar, improved backtesting engine.
Used by: Exness, AvaTrade, Pepperstone, IC Markets
Demo account
Platform
A practice account funded with virtual money. Identical to a live account in terms of platform and pricing but with no real financial risk. Use a demo account to learn the platform, test strategies, and get comfortable with order types before depositing real money.
Tip: All major EU brokers offer free unlimited demo accounts
ECN broker
Account
Electronic Communication Network. An ECN broker routes your orders directly to liquidity providers (banks, institutions) rather than acting as the counterparty. Offers tighter spreads but charges commission. ECN = STP (Straight Through Processing) in practice, though brokers use the terms differently. True ECN provides direct market access with no dealing desk intervention.
Example: Raw spread 0.0 pips + $3.50 commission/lot each way
Market maker
Account
A broker that takes the opposite side of your trade internally rather than routing it to the market. Market makers set their own bid/ask prices and profit from the spread. Not inherently bad — most retail brokers are partly market makers. EU-regulated market makers must still comply with best execution requirements under MiFID II.
Example: Many major retail brokers operate as market makers on Standard accounts
6. EU regulatory terms
These terms are specific to trading with EU-regulated brokers. Knowing them helps you assess broker safety.
ESMA
EU Reg
European Securities and Markets Authority. The EU-wide financial regulator that issued the leverage limits and other retail CFD rules in 2018. ESMA rules apply to all brokers regulated by CySEC (Cyprus), FCA (UK — post-Brexit, separate), BaFin (Germany), AMF (France), and other EU national regulators. The core retail protections: max 30:1 leverage on majors, negative balance protection, mandatory risk warnings.
MiFID II
EU Reg
Markets in Financial Instruments Directive II. The EU regulatory framework governing all financial instruments including CFDs. Requires brokers to: provide Key Information Documents (KIDs), follow best execution obligations, disclose conflicts of interest, categorise clients as Retail, Professional, or Eligible Counterparty, and maintain records of all communications.
CySEC
EU Reg
Cyprus Securities and Exchange Commission. Because Cyprus is an EU member state, CySEC-regulated brokers hold a passportable EU licence under MiFID II — meaning they can legally operate across all 27 EU countries. Many major forex brokers are registered in Cyprus for this reason. CySEC licence IDs are formatted as NNN/NN (e.g. Exness: 178/12, AvaTrade: 347/17).
ICF — Investor Compensation Fund
EU Reg
The Cyprus-based compensation scheme protecting retail clients of CySEC-regulated brokers up to €20,000 per client if the broker becomes insolvent. Only covers retail clients — Professional clients are excluded. Does not cover trading losses, only the firm's failure to return client funds. UK equivalent is FSCS (up to £85,000).
KID — Key Information Document
EU Reg
A standardised 3-page document required by EU law (PRIIPs regulation) for every CFD product offered to retail clients. Includes: product description, risk indicator (1–7 scale), cost breakdown, performance scenarios, and how to complain. Brokers must provide KIDs for each instrument. Read these before trading a new product.

Frequently asked questions
What is a pip in forex trading?
A pip (percentage in point) is the smallest standard price move in a currency pair. For most pairs quoted to 4 decimal places (e.g. EUR/USD), one pip equals 0.0001. On a standard lot (100,000 units), one pip equals approximately $10 in profit or loss. For JPY pairs quoted to 2 decimal places, one pip equals 0.01.
What does leverage mean in EU forex trading?
Leverage lets you control a large position with a small deposit. Under ESMA rules, EU retail traders are limited to a maximum of 30:1 on major currency pairs. This means €1,000 controls €30,000 of currency. Leverage amplifies both profits and losses — a 1% adverse move on a 30:1 leveraged position wipes 30% of your margin.
What is the spread in forex?
The spread is the difference between the buy price (ask) and sell price (bid). It is the broker's primary fee on most retail accounts. For EUR/USD, a typical retail spread is 0.8–1.5 pips on a Standard account and 0.0–0.3 pips on an ECN/Raw account (plus a per-lot commission). Spreads widen during low-liquidity periods.
What is margin in forex?
Margin is the collateral you must deposit to open and maintain a leveraged position. At 30:1 leverage, the margin requirement is 3.33% — to open a €10,000 position you need €333 in margin. Margin is not a fee — it's returned when you close the trade (adjusted for P&L). If your equity falls below the margin call level, the broker alerts you to deposit more or close positions.
What is a CFD and is it the same as forex?
A CFD (Contract for Difference) is a derivative product that tracks the price of an underlying asset without you owning it. Most retail forex trading in the EU is done through CFDs on currency pairs. CFD forex brokers regulated under MiFID II must provide Key Information Documents and comply with ESMA leverage limits.
What is a lot size in forex?
A lot is a standardised unit of measurement for a forex trade. A standard lot is 100,000 units of the base currency. A mini lot is 10,000 units and a micro lot is 1,000 units. Most EU retail traders start with micro or mini lots to manage risk at small account balances.
What does stop loss and take profit mean?
A stop loss is an order that automatically closes your trade at a pre-set loss level, capping your downside. A take profit closes the trade at a target profit. Together they define your risk:reward ratio before you enter. Always set a stop loss on every trade — do not rely solely on negative balance protection for loss control.
