Broker
Quick Answer
A broker is a person or firm that facilitates transactions in financial instruments for clients. Depending on the market and regulatory framework, a broker may receive and execute client orders, provide access to trading venues or perform other intermediary functions. The precise legal meaning and responsibilities of a broker vary between jurisdictions and financial markets.
How does a Broker work?
A broker acts as an intermediary in the process of buying or selling financial instruments.
For example, an investor wishing to buy shares generally does not interact directly with every potential seller in the market. Instead, the investor submits an order through a brokerage firm, which facilitates or executes the transaction according to the applicable market structure.
FINRA describes a broker as an investment professional who acts as an intermediary between buyers and sellers of securities and executes transactions. Brokerage firms can provide clients with access to markets for products such as shares and bonds.
The exact role can differ significantly depending on whether the firm operates in securities, futures, foreign exchange, derivatives or another market.
Key features of a Broker
Several characteristics are commonly associated with brokers:
Intermediary role: Brokers generally facilitate transactions on behalf of clients.
Order handling: A broker may receive, transmit or execute client orders.
Market access: Brokerage firms can provide the systems and infrastructure through which clients access financial markets.
Compensation: Brokers may earn commissions, fees, spreads or other forms of compensation depending on their business model.
Different broker types exist: Securities brokers, futures intermediaries and introducing brokers can have different legal definitions and responsibilities.
Regulation varies: Registration, capital, conduct and client-protection requirements depend on the jurisdiction, product and broker structure.
Broker and dealer are not identical concepts: A broker generally acts for clients, while a dealer trades for its own account.
In U.S. securities terminology, the SEC distinguishes a broker—someone engaged in buying or selling securities for the accounts of others—from a dealer, which buys or sells securities for its own account.
Simple Broker example
Suppose a client wants to buy:
100 shares of Company A
The client submits an order through a brokerage platform.
The broker or brokerage infrastructure may then route or execute the order in accordance with the relevant market and execution arrangements.
If the shares execute at:
$50 per share
the transaction value would be:
100 × $50 = $5,000
The broker has facilitated the client's access to the transaction.
Depending on the firm's business model, separate commissions, spreads, financing charges or other costs may apply.

Potential benefits and uses
Brokers provide infrastructure that can make financial markets accessible to individual and institutional clients.
Their functions may include:
accepting and processing orders;
providing trading platforms;
connecting clients with markets or execution arrangements;
maintaining transaction and account records;
providing market information or research where applicable;
supporting account administration;
facilitating settlement or working with firms that perform settlement functions.
FINRA notes that brokerage firms vary considerably in the services they provide. Some focus mainly on trade execution, while others may provide broader investment-related services.
The availability of any specific service depends on the broker and should not be assumed from the word “broker” alone.
Risks, limitations and common misconceptions
A common misconception is that all brokers operate in exactly the same way.
They do not.
A broker's role can depend on:
jurisdiction;
regulatory status;
financial instrument;
execution model;
whether it acts only as intermediary or also as principal;
relationships with exchanges, liquidity providers or other financial institutions.
Another misconception is that broker and dealer mean the same thing. In securities-market terminology, a broker generally conducts transactions for customers, while a dealer conducts transactions for its own account. A single firm can sometimes perform both roles and therefore be described as a broker-dealer.
A broker should also not automatically be confused with an Introducing Broker (IB). In U.S. derivatives regulation, the CFTC defines an introducing broker as an intermediary that solicits or accepts certain client orders but does not accept the client funds or property used to margin or secure those trades.
Finally, using a broker does not remove trading risk. Market prices can move adversely, orders may execute differently from expected prices, and the financial strength, regulatory status and operating model of the intermediary can also matter.
