Most new traders spend weeks studying strategies before giving any serious thought to who they’ll trade through. That’s the wrong order. Your broker/dealer shapes what you can trade, what it costs, what leverage you have access to, and what your protections are if something goes wrong. Understanding the landscape before you commit is worth the time.
What is a broker/dealer?
A broker/dealer is a licensed firm that facilitates transactions in financial instruments. The term describes two functions: acting as a broker, the firm executes transactions on behalf of clients and earns a commission. Acting as a dealer, it trades from its own inventory. Most large financial institutions do both.
The category is broad. A real estate brokerage, a stock brokerage, and a commodities firm are all broker/dealers — they hold different licenses and serve different markets. If you want to buy shares of a publicly traded company, you use an equities broker/dealer. If you run a business with commodity exposure, you might work with one licensed in futures. Many of the largest institutions hold multiple licenses simultaneously and service multiple markets at once.
Prime brokers
Prime brokers provide bundled services to hedge funds, family offices, and professional capital managers. Their offering goes well beyond trade execution — it includes custody, securities lending, leverage facilities, risk reporting, and capital introduction.
Most individual investors won’t interact with a prime broker directly. But if your long-term goal is managing capital professionally — building a fund, raising outside capital, running institutional strategies — understanding what prime brokers offer and which firms provide those services is foundational knowledge worth having early.
Major prime brokerage operations include:
- Goldman Sachs
- JP Morgan
- Morgan Stanley
- Bank of America (Merrill Lynch)
- Citibank
- Barclays
- UBS
- BNP Paribas
- Interactive Brokers

Retail brokers
Retail brokers service individual investors — offering brokerage accounts, trading platforms, research tools, and in some cases advisory services. Many are subsidiaries of the same large institutions that run prime brokerage operations; others are independent.
Platform capabilities, commission structure, margin requirements, and account approval processes vary significantly. Worth evaluating:
- Charles Schwab (includes the thinkorswim platform, formerly TD Ameritrade’s)
- Fidelity
- Interactive Brokers
- E*TRADE (Morgan Stanley)
- Tastytrade
- Merrill Edge (Bank of America)
- TradeStation
- Ally Invest
- Webull
Before selecting a broker, clarify what you’re trying to accomplish. A firm suited for long-term equity investing may not be the right fit for active options or futures trading. The Options Overview — Choosing a brokerage covers what to look for in detail, including the difference between full-service and discount brokers. The Account approval levels section is equally important — your broker’s approval level determines which strategies you can actually execute.
Introducing brokers
Introducing Brokers (IBs) are most relevant in the futures, commodities, and forex space. An IB acts as an intermediary between the client and a Futures Commission Merchant (FCM). The IB handles the client relationship — onboarding, advisory services, strategy discussion — while delegating trade execution and account custody to the FCM.
One important distinction: IBs do not hold or accept client funds. All money and accounts are maintained at the FCM. This is worth understanding clearly before working with any IB.
The regulatory structure differs from equities:
- Equities: Registered with the SEC, governed by FINRA
- Futures / Commodities / Forex: Registered with the CFTC, governed by the NFA
When evaluating any firm, verifying their registration with the appropriate regulator is straightforward and free. It tells you immediately what they’re licensed to do — and if something doesn’t match what they’re telling you, that’s a clear signal. The Options Definitions reference covers regulatory terms you’ll encounter as you dig into this.
Most large firms operate as all three
This is what makes the landscape complex: most major banks and financial institutions hold multiple licenses simultaneously, operating as prime broker, retail broker, and introducing broker across different divisions for different client segments. A firm like Goldman Sachs or JP Morgan services hedge fund clients through its prime brokerage arm, retail clients through its consumer division, and commodity clients through its futures brokerage — often concurrently.
Understanding this overlap matters as you develop industry relationships and start to understand where you fit in the broader capital structure. The product or service a firm offers you depends heavily on which division is talking to you — and which license that division holds.
A note from Ryan
I was a former Series 3 and Series 30 licensee, both on the commodity side. Understanding the distinction between IBs, FCMs, and the regulatory bodies governing them was a core part of the licensing process. The practical value showed up early: knowing who you’re dealing with, what their actual license covers, and what your protections are as a client changes how you evaluate every firm you consider working with.
Take the time to research before you open an account. The decisions you make here have a long shelf life.
