A Forex broker is a financial intermediary that gives retail traders access to the currency market by quoting prices, holding client accounts, and executing buy and sell orders. Most individuals cannot deal directly in the interbank network, so the broker sits between the trader and liquidity providers such as banks and other dealing firms. The same firm supplies a trading platform, account records, and, where the law requires it, identity checks before live funds are accepted. Knowing what a broker does – and what it does not do – comes before comparing brands or opening an account.

What Does a Forex Broker Do?
Forex trading is the exchange of one currency for another. A retail broker makes that exchange possible for clients who are not banks. In practical terms, the broker publishes a bid and an ask for each currency pair, accepts an order from the trader’s account, and reports a fill together with the resulting profit or loss.
The broker is also the custodian of the cash you deposit. That money is used as margin to support open positions. It is not a loan to the broker for its own trading, and it is not a pooled investment product. The firm’s job is to keep the account ledger, apply overnight financing where a position is held past the daily rollover, and process withdrawals back to the client when requested.
Because retail clients cannot call a dealing desk at a large bank and ask for a million-euro ticket, the broker aggregates many small orders. Some of those orders are matched internally. Others are passed to external liquidity. The commercial details of that process are what separate types of Forex brokers from one another. The function is the same: the broker is the access point to the market.
How a Broker Executes an Order
When you click buy or sell, the platform sends an instruction to the broker’s dealing system. That system either fills the order against its own book or routes it onward. You then receive a confirmation: instrument, direction, volume, price, and time. Slippage can occur if the quoted price moves before the fill, especially around news.
A dealing-desk (market maker) broker may take the other side of your trade. A no-dealing-desk broker typically sends the order to banks, other brokers, or an electronic network and charges a spread, a commission, or both. Neither model is automatically better. Each changes how prices are formed and whether the firm has a direct conflict with the client’s P/L. The dedicated guide to broker types covers those models in full.
Execution quality is visible in three numbers: the spread at the moment of the click, any commission on the ticket, and the difference between the requested price and the fill. A 0.8 pip delay on a standard lot of EUR/USD is about $8 of extra cost if each pip is worth $10.
Requotes appear when the broker rejects the requested price and offers a new one. They are more common on dealing-desk books in fast markets. STP and ECN-style accounts more often fill with slippage instead of a requote. The platform you use does not change the legal counterparty: the broker still operates the account.
The Legal Entity Behind the Brand
One brand can operate several companies: an EU investment firm, a UK subsidiary, an offshore dealer. Each has its own licence, leverage cap, and complaint venue. The account you open is with one of them. Marketing pages mix the brand. Legal documents name the company. Read that name before you fund.
A licence you can verify on a regulator’s register is a starting filter, not a guarantee of good fills. Authorities often cited in retail Forex include the UK FCA, Australia’s ASIC, CySEC for many EU-facing brands, and, for US-facing dealers, the CFTC with NFA membership. Licence numbers change and should be checked on the register, not copied from a banner. This page does not list live licence IDs.
Offshore incorporation is common. A brand may run a tightly supervised entity for clients in one region and a lightly supervised entity for clients elsewhere. Product features such as leverage, bonuses, and available pairs can differ between those entities. Regulation is an attribute of the legal company on your contract, not of the website’s logo.
Trading Accounts and KYC
Opening a live account is similar to opening a bank account. The broker must identify the client (know-your-customer checks), record the source of funds where rules require it, and classify the account as retail or professional. Until those steps are complete, withdrawals and sometimes even deposits can be blocked. A demo account uses a parallel ledger with virtual money and usually needs only an email address.
A demo copies the order ticket and often the same price feed, but fills are not sent to the live dealing book. Slippage, requotes, and gap risk on a demo can look milder than they are with real money. The demo is for learning the platform and the mechanics of lots, stops, and margin – not for proving that a strategy will survive live conditions.
Brokers group live accounts by minimum deposit, spread model, and commission. Names such as Standard, Raw, ECN, or Pro are marketing labels. What matters is whether the quote is a markup on the spread, a commission per lot, or both, and whether hedging two opposite positions on the same pair is allowed. Some firms also advertise funded-account promotions; a deposit bonus changes the cash credited to the account and usually adds extra withdrawal conditions. Those terms belong to the offer, not to the definition of a broker.
Balance, Equity and Leverage
Almost every retail Forex account includes leverage. Leverage is a ratio that sets how much notional the account can control relative to the margin locked for a trade. At 30:1, $1 of usable margin supports $30 of position size. At 100:1, the same dollar supports $100. The ratio does not change the size of a gain or a loss on the market; it only changes how much cash must sit in the account to open the trade.
Retail caps on leverage differ by region. European retail clients are often limited to 30:1 on major pairs. Other jurisdictions allow higher ratios. The number printed on a website is not a recommendation. Higher leverage simply makes it easier to open a position that is too large for the account.
The platform shows more than one balance figure. Balance is cash plus closed P/L. It ignores open trades. Equity is balance plus the floating P/L of open positions – the amount you would have if every trade were closed at the current quote. Used margin is the sum locked against open trades. Free margin is equity minus used margin, and it is what remains to open new trades or to absorb further losses. If equity falls toward used margin, the broker can issue a margin call and then close positions automatically.
Spreads, Commission and Swap
A broker is a commercial firm. It is paid from the spread, from commission, from overnight swap, or from a mix of the three. The spread is the gap between the bid (the price at which you can sell) and the ask (the price at which you can buy). On EUR/USD, a quote of 1.10000 / 1.10012 is a 1.2 pip spread. You start every round-turn slightly behind the mid-market price. A pip is the usual unit for that gap.
Commission, where it exists, is usually charged per side or per round-turn on the lot, not on the account cash. Swap (also called rollover) is applied when a position is held through the broker’s end-of-day cut-off. It can credit or debit the account depending on the pair, the direction, and the interest-rate differential. The table below is an illustrative cost sheet for one standard lot of EUR/USD. Live figures must be read from the broker’s specification.
| Cost item | Example figure | Cash impact on 1.00 lot |
|---|---|---|
| Spread 1.2 pips | $10 per pip | $12 to break even |
| Commission $7 per lot per side | Round-turn | $14 |
| Swap, long, one night | −$6.50 (example) | −$6.50 if held overnight |
| Total friction, same-day round-turn | Spread + commission | $26, or about 2.6 pips |
Live figures must be read from the broker’s specification, not from a marketing banner.
Worked Example: Margin and Cost
Suppose EUR/USD trades at 1.1000 and you open 0.10 lot (10,000 euros) on a USD account. Notional value is 10,000 × 1.1000 = $11,000. At 30:1 leverage the required margin is about $11,000 ÷ 30 = $366.67.
If the pair moves 20 pips against you, a mini lot loses about $1 per pip, so the floating loss is $20. The spread paid at entry is extra: 1.2 pips × $1 ≈ $1.20. Add a $1.40 round-turn commission (one tenth of the $14 in the table) and the trade needs a little over 22 pips in its favour before it shows a net profit.
None of these numbers is a live quote. They show how the broker’s pricing and the position size interact. Spread is taken from traded size, not from idle cash: 1.2 pips costs about $12 on 1.00 lot and about $0.12 on 0.01 lot.
Position sizing and stop placement belong to Forex risk management, not to the broker’s marketing copy.
Regulation in Outline
A regulated Forex broker is a firm that holds a licence (or equivalent authorisation) from a financial authority and must follow conduct, capital, and client-money rules. Typical requirements include segregating client funds from the firm’s own cash, keeping a minimum of regulatory capital, reporting trades, and offering a complaints path. The authority’s name is not a guarantee that every ticket will be filled as hoped. It is a statement that the firm is supervised.
This page explains what regulation is. It is not a checklist for picking a firm. For a step-by-step comparison of safety, costs, platforms, and withdrawals, use the separate guide on how to choose a Forex broker.
The broker also publishes contract specifications: contract size, minimum volume, stop level, swap method, and trading hours. Those figures decide whether a 0.01 lot is allowed and how a weekend gap is treated. They should be read before size is increased.
What a Forex Broker Is Not
A broker is not your investment adviser unless a separate advisory contract says so. Educational webinars and daily market notes are marketing and teaching material. They are not personal recommendations. A broker is also not an exchange. There is no single central Forex exchange for retail spot CFDs; prices are the broker’s quotes, often derived from a panel of banks.
A broker does not remove market risk. Leverage, spreads, and fast execution can make losses larger and faster than a cash purchase of currency at a high-street bank. If equity falls below the maintenance margin, positions can be closed whether or not you agree with the price. Negative-balance protection, where it is offered, is a product feature of a given entity, not a universal law.
Finally, a broker is not the same as a signal provider, a PAMM manager, or a social-copy network. Those services may sit on top of a brokerage account. The legal counterparty for the fill remains the broker named on the account documents.
Trading CFDs and Forex with leverage can result in losses that exceed the deposit. This page is educational and is not investment advice. Figures in the examples are illustrative and should be checked with the broker before they are used on a live order.
Frequently Asked Questions About Forex Brokers
What is a Forex broker?
A Forex broker is an intermediary that gives retail traders access to currency prices, holds client accounts, and executes buy and sell orders on those accounts.
How does a Forex broker make money?
Most brokers earn from the bid–ask spread, from a commission per lot, from overnight swap, or from a combination of those charges. The mix depends on the account type.
Do I need a Forex broker to trade currencies?
Retail traders who want leveraged spot or CFD Forex almost always need a broker (or a bank with an equivalent dealing desk). Direct access to the interbank market is not available to most individuals.
What is the difference between a broker and a trading platform?
The broker is the firm that holds the account and is the counterparty or agent for the trade. The trading platform is the software used to view prices and send orders to that firm.
What is the difference between account balance and equity?
Balance is cash plus closed profit and loss. Equity is balance plus the floating profit or loss of open positions. Free margin is equity minus margin already used.
What does it mean if a Forex broker is regulated?
It means a named legal entity is authorised by a financial authority and must follow that authority’s capital, conduct, and client-money rules. It does not guarantee profitable trades or perfect execution.
Is a demo account enough to judge a broker?
A demo account is useful for learning the platform and order types. Live fills, withdrawals, and slippage can differ, so a demo is not a full test of the firm.
Is every Forex broker a market maker?
No. Some brokers take the other side of client trades (dealing desk). Others route orders to external liquidity (STP or ECN-style). Many groups operate more than one model across account types.
Summary
A Forex broker is the intermediary that quotes currencies, holds your cash as margin, and turns platform orders into fills. It is paid through spread, commission, and swap. It may act as market maker or pass orders to other liquidity, which is why broker type matters for execution. Regulation describes the legal entity on the contract, not the quality of every trade.
Once the role of the broker is clear, two follow-on questions are practical rather than definitional: which execution model you are dealing with, and which firm you will actually use. Those answers live in the guides to broker types and to choosing a broker, not in this definition.
