A CFD broker contract is not a casual sign-up form. It is a legally binding agreement that defines the terms under which you trade Contracts for Difference. Despite the speed of online account opening, the underlying contract, often titled “Client Agreement,” “Terms of Business,” or “Customer Agreement”, can run tens of thousands of words. Brokers licensed by the Financial Conduct Authority (FCA), the Cyprus Securities and Exchange Commission (CySEC), or the Australian Securities and Investments Commission (ASIC) embed critical clauses that directly affect your trading costs, risk exposure, and rights in dispute. This article walks you through each key provision, explaining what to look for and what the fine print usually means.
1. Scope and Governing Law
The opening section of a broker contract defines the legal framework. It specifies which regulator oversees the broker and under which jurisdiction disputes are resolved. For example, a broker registered with the FCA in the United Kingdom will state that the agreement is governed by English law. A broker regulated by CySEC will refer to Cypriot law and the European Securities and Markets Authority (ESMA) rules. This matters because regulatory protection levels differ. FCA-regulated brokers, for instance, must offer negative balance protection to retail clients under ESMA guidelines since 2018. ASIC-regulated brokers introduced similar protections under ASIC’s Product Intervention Order in 2021.
Check whether the contract mentions “Retail Client,” “Professional Client,” or “Eligible Counterparty.” If you are classified as a retail client, you receive the highest level of regulatory safeguards, including leverage caps, mandatory risk warnings, and access to the Financial Ombudsman Service. If the broker has classified you as a professional client (sometimes after a simple online quiz), you lose many of those protections. Read the classification clause carefully and confirm your status matches how you applied.
2. Product Definition: What Is a CFD?
The contract will define the financial instrument you are trading. Look for a section titled “Definitions” or “Interpretation” and find the entry for “Contract for Difference” or “CFD.” It usually reads something like: “a contract between the Client and the Company the purpose of which is to obtain the difference between the opening price and the closing price of the underlying asset without physical delivery.” This is the legal basis of the instrument. The definition may also list which underlying asset classes are available, shares, indices, forex pairs, commodities, and cryptocurrencies. For a full explanation of the product, see What Is a CFD?.
Some contracts add a clause stating that the broker has the unilateral right to change the list of available instruments or close a position in a particular asset without prior consent. This is particularly common for CFDs on crypto and volatile small-cap shares. If you see such a clause, note that the broker can act to protect its own risk, and you may not have the right to hold a position to expiry if the broker decides to delist it.
3. Leverage and Margin Requirements
Leverage in CFDs is the single most powerful, and dangerous, feature of the product. The contract will state the maximum leverage offered for each asset class. Under ESMA rules for retail clients, major forex pairs are capped at 30:1, non-major forex at 20:1, indices at 20:1 (with some exceptions for major indices like the FTSE 100 at 10:1), commodities at 10:1, and shares at 5:1. Crypto CFDs are often capped at 2:1 for retail clients in the EU and UK. For professional clients, leverage can go much higher, 100:1 or 500:1 is not uncommon.
The margin clause will specify both initial margin (the deposit required to open a position) and maintenance margin (the minimum equity needed to keep the position open). These are usually expressed as percentages. For example, a 1% initial margin on a £10,000 position means you need £100 in your account. A maintenance margin of 0.5% means your equity cannot fall below £50. If the contract says “margin is subject to change without prior notice,” that is a warning sign. While many brokers do adjust margins before major news events, you should check the broker’s published margin schedule separately. For a deeper look at margin mechanics, read Margin Requirements.
3.1 Margin Calls and Liquidation
The contract must describe the sequence of events that occurs when your account equity drops below the margin threshold. This is the margin call and liquidation procedure. Standard wording: “If the Client’s equity falls below 50% of the initial margin requirement, the Company reserves the right to close any or all open positions without prior consent.” Some brokers set the threshold at 100% (meaning positions are closed as soon as equity equals the required margin). Others use a tiered system, a warning at 80%, automatic partial closing at 50%. The key point is the “without prior consent” phrase. Once triggered, the broker can act instantly. You cannot demand a delay or a phone call. Be sure you understand the exact percentage and whether the broker closes all positions or only the most unprofitable one.
Important: Look for the phrase “negative balance protection.” Under ESMA and ASIC rules, retail clients must have this protection, meaning the broker cannot seek more than your deposited amount if the market gaps against you. If the contract lacks this clause, you could be liable for debts far exceeding your deposit.
4. Costs: Spreads, Commissions, and Overnight Financing
The broker contract will list the costs you pay, though not always in a transparent table. You need to locate the sections on “Spread,” “Commission,” and “Swap” or “Overnight Financing.”
4.1 Spread
The spread in CFDs is the difference between the bid price (sell) and the ask price (buy). The contract will state that the spread is variable and determined by the broker based on market conditions. For major forex pairs like EUR/USD, typical spreads on standard accounts are 0.6-1.2 pips; on raw or “zero spread” accounts, commissions apply instead. For indices, spreads on the FTSE 100 might be 1-2 points; for the S&P 500, 0.5-1.5 points. The contract should say that spreads may widen during volatile periods or news announcements. Do not expect a fixed number in the contract itself, spreads are usually published on the broker’s website and can change.
4.2 Commission
Commissions in CFDs appear mostly on share CFDs and on raw forex accounts. A common structure for UK share CFDs is 0.1% of the trade value, with a minimum charge of £9 per order. For US shares, the minimum might be $10. For forex, a raw account might charge $3.50 per lot per side (i.e., $7 round turn). Read the contract for the exact calculation: some brokers charge commission on both opening and closing, others only once. The contract should also state whether VAT or other taxes are added.
4.3 Overnight Financing (Swap)
If you hold a CFD position past a certain cut-off time (usually 22:00 London time on the spot market, and earlier for some brokers), you are charged or credited overnight financing (swap). The contract should describe the calculation: Position Size × (Reference Rate ± Broker Markup) / 360. The reference rate is often the London Interbank Offered Rate (LIBOR) or its successor, the Secured Overnight Financing Rate (SOFR), plus a broker markup, typically 2% to 3% per annum. For long positions, you pay the reference rate plus the markup; for short positions, you receive the reference rate minus the markup. Triple swaps are applied on Wednesday for forex to account for weekend settlement. The contract must disclose the markup, but the exact rate may be listed on the broker’s website. If the wording says “swap rates are subject to change at any time,” that is standard, but you should be able to check the current rates in the trading platform.
5. Order Execution and Slippage
The execution policy defines how your orders are filled. Most CFD brokers operate under a “Straight Through Processing” (STP) model or a “Market Maker” model. The contract will state something like: “The Company acts as principal and counterparty to all Client trades.” That is typical of a market maker. It means the broker takes the opposite side of your trade. In an STP model, the broker passes your order to a liquidity provider. The contract should also describe slippage and gapping, the difference between the requested execution price and the actual fill price, especially during high volatility or low liquidity. Many contracts have a clause stating that slippage is considered normal and that the broker does not guarantee execution at stop-loss or limit levels outside of normal market conditions.
5.1 Stop Loss and Guaranteed Stop Loss
Look for the specific terms regarding stop-loss orders. Standard stop-loss orders are not guaranteed; they become market orders when triggered, and the actual fill may be worse than the stop price. The contract should include a “Guaranteed Stop Loss” (GSL) option, guaranteed stop-loss, which ensures closure at the exact price you set, regardless of gapping. The GSL will come with a premium or a wider spread. The contract must disclose the cost and conditions: typically, GSLs are only available on certain instruments (major forex, some indices) and cannot be placed within a certain percentage of the current market price (e.g., 0.5% for major pairs).
5.2 Limit Orders
Limit orders allow you to set a price at which you want to buy or sell. The contract will state that limit orders are executed as the market reaches the limit price, but partial fills can occur if liquidity is insufficient. Some brokers offer “fill or kill” (FOK) or “immediate or cancel” (IOC) variants; check if those are described. The contract should also clarify the handling of limit orders during off-market hours or around news events.
6. Position Sizing and Lot Requirements
Every CFD broker defines position sizes in terms of “lots,” “units,” or “contracts.” For forex, a standard lot is 100,000 units of the base currency; a mini lot is 10,000; a micro lot is 1,000. For indices, the contract might define a lot as “1 Index CFD per point” or “CFD representing a fixed notional value, e.g., £10 per point.” The contract should specify the minimum trade size (e.g., 0.01 lots for forex) and the maximum trade size (often capped at 100 standard lots per order). You should also check the position sizing rules that apply to your account type. Some brokers allow fractional share CFDs (e.g., 0.1 share of Apple) while others require whole shares.
The contract may include a “close only” clause. If your account equity falls below a certain level (like 200% of used margin), you may be restricted to closing positions only, no new openings. This is a common protection for both the broker and the client, but it may appear in the fine print under “Account Management” or “Trading Restrictions.”
7. Fees, Dividends, and Corporate Actions
Beyond trading costs, the contract will list other fees: deposit fees, withdrawal fees, inactivity fees, and currency conversion fees. Deposit fees are rare on major brokers (e.g., IG Group or CMC Markets do not charge for bank transfers), but some smaller brokers charge a percentage. Withdrawal fees are more common, often £10 or €10 per withdrawal, or a percentage (1-2%) for credit card withdrawals. Inactivity fees appear after a period of no trading, typically 6 to 12 months. The amount can be $10 to $50 per month, deducted from your account. Currency conversion fees apply if your account base currency differs from the CFD instrument’s currency, often 0.5% to 1% of the trade value.
Dividend adjustments: If you hold a share CFD over the ex-dividend date, the contract will state that your account is credited (for long positions) or debited (for short positions) with an amount equal to the dividend. The adjustment is usually applied on the ex-dividend date. The contract should disclose whether the dividend is gross or net of tax. For UK shares, the adjustment is often the gross dividend; for US shares, it may be net of the 15% withholding tax. Read the specific clause to avoid surprises.
Corporate actions: For share CFDs, the contract should outline how stock splits, reverse splits, mergers, and takeovers are handled. The standard approach is that the broker will adjust the CFD position to reflect the corporate action, either by changing the number of units and the price or by closing the position at the last trading price. If the broker intends to close the position at its discretion (e.g., in a cash takeover where the underlying shares are delisted), the contract must state the notice period, often zero to 48 hours. CFDs on shares are particularly affected by these events, so traders should review this section before trading around earnings or merger announcements.
8. Reporting, Complaints, and Dispute Resolution
The contract will specify how you receive trading statements and confirmations. Usually, you can access them through the broker’s online platform or via email. The frequency may be: daily (for open positions), monthly, or quarterly. Some brokers provide a real-time view in the platform rather than separate reports. The clause should say that statements are deemed correct unless you object within a certain period, commonly two to ten business days. If you miss that window, you may forfeit your right to challenge a trade or balance.
Dispute resolution is a critical section. The contract must name the relevant ombudsman service: the Financial Ombudsman Service (FOS) in the UK, the Financial Services Ombudsman in Ireland, or the Office of the Ombudsman for Banking Services in South Africa. For CySEC brokers, the Financial Ombudsman of the Republic of Cyprus is the first step, followed by the European Consumer Centre. The contract will also mention the possibility of arbitration, but note that arbitration is usually binding and often more expensive. If the contract specifies a jurisdiction outside your country of residence (e.g., the British Virgin Islands for a broker licensed there), your legal recourse may be limited. Always confirm that the broker is registered with a reputable ombudsman scheme and that the contract includes a clear complaint procedure (step-by-step: internal complaint → regulator → ombudsman).
9. Termination and Suspension
A broker can terminate the agreement or suspend your account under certain conditions. Common causes: inactivity for 12 months, providing false information, breach of margin terms, or any illegal use of the account. The contract will state that the broker can close all open positions upon termination, sometimes immediately, sometimes after a notice period (e.g., 5 business days). You should also look for a clause that allows the broker to “close out any open positions if the Company deems it necessary to protect its interests.” This is a broad discretion clause. While regulators frown upon arbitrary use, it is present in many contracts. If you trade large positions or hold long-term positions, this clause poses a real risk of forced closure during a news event that the broker considers risky to its own exposure.
On the client side, you typically have the right to terminate the agreement at any time with written notice, but the broker may still apply fees for pending transactions. If you close your account, details about how to withdraw remaining funds should be specified, some brokers require a minimum withdrawal amount (e.g., £50) and charge a fee if the balance is below a threshold.
10. Practical Steps Before Signing
Before you click “Accept,” take these steps:
- Print or save a PDF of the full client agreement. Brokers often update terms with 10 days’ notice. Having the original version helps you compare changes.
- Highlight key numbers: margin percentages, swap charges, commission rates, fee thresholds, and the liquidation threshold.
- Check for negative balance protection, if it is missing, consider a different broker.
- Find the regulatory warnings. The contract should include statements such as “CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 74% of retail investor accounts lose money when trading CFDs with this provider.” That is the required risk warning for FCA brokers.
- Cross-reference the contract with the broker’s website. Sometimes the website promises one thing (e.g., no inactivity fee) but the contract says something else. The contract prevails in a dispute.
- Ask for clarification via live chat or email. Save the correspondence. If a support agent tells you that a certain fee does not apply, but the contract says it does, the written contract may still be enforced, but your evidence could help in a complaint.
Reading a CFD broker contract thoroughly is time-consuming, but it is the single most effective way to avoid unexpected losses. The clauses on leverage, margin, costs, and forced closure can cost or save you hundreds or thousands of pounds.
