In the financial world, understanding what a broker is has become essential for every investor. So, what’s the answer? In essence, a broker is an agent that connects the buyer with the seller in financial markets.
However, there are different types of brokers, from those specializing in stock trading to others focused on currencies. Each one is designed to suit different investment styles and goals.
For that reason, in this article you’ll find everything you need on the subject so you can choose the best broker.
A broker is an intermediary that facilitates trading in the markets and can be either an authorized entity or individual. Its main function is to execute the buy or sell orders it receives from its clients, whether they are independent traders, businesses, or individuals.
Now, what is a broker in trading?
It’s the one who enables access to the financial markets through a specialized digital platform. Without it, operating would not be possible.
A broker acts as a bridge between the investor and the financial markets. Whether to buy or sell assets like stocks, currencies, cryptocurrencies, or commodities directly.
The main functions of a broker are:
Execute buy/sell orders as indicated by the client, without making decisions on their behalf.
Provide access to proprietary or digital platforms.
Offer charts, indicators, and analysis tools.
Provide access to financial news and real-time quotes.
Safeguard and protect the client’s funds in segregated accounts.
It’s important not to confuse the role of a broker with that of a trader. The following table can help you understand the differences between these two terms:
Trader | Broker |
Is the client of the broker. | Is the intermediary between the trader and the market. |
Makes investment decisions. | Executes the orders received from the trader. |
Places buy or sell orders. | Processes them in the market. |
Assumes the profit or loss of each trade. | Earns a commission regardless of the outcome. |
Relies on technical or fundamental analysis. | Does not analyze or decide for the client. Just facilitates the trade. |
May trade short- or long-term, depending on their style. | Provides tools for various types of trading. |
Their activity gives meaning to the existence of the broker. | Their role depends on the existence of traders. |
There are different types of brokers depending on the financial product they offer:
They focus on the stock market, allowing investors to trade shares of publicly listed companies. This is the most well-known type and is usually sought out for investing in the world’s major indices and stock exchanges.
Broker examples: Interactive Brokers, Charles Schwab.
They specialize in the currency exchange market—the largest and most liquid in the world.
This type of broker operates online and enables trading with low capital, from any device, and with extended trading hours.
In this case, there are two categories:
Dealing Desk (Market Maker): They create their own internal market.
Non-Dealing Desk: They send orders directly to the market through liquidity providers.
Broker examples: IC Markets, Pepperstone.
They facilitate access to futures contracts traded on regulated exchanges. This allows investing in assets such as commodities, energy, currencies, or stocks, focusing on speculation or risk hedging.
Broker examples: NinjaTrader, TD Ameritrade.
Used to trade derivatives known as options, whose value depends on the performance of an underlying asset.
They are ideal for advanced investment strategies in instruments like stocks, currencies, or commodities.
Broker examples: Tastytrade, Thinkorswim (by TD Ameritrade).
They provide access to various investment funds, such as bonds, treasury bills, or mutual funds. These are often chosen by those looking to diversify their portfolios with lower-risk or long-term products.
Broker examples: Vanguard, Fidelity.
This type of broker acts as an intermediary in the purchase and sale of real estate. They also offer guidance throughout the entire process.
Broker examples: Keller Williams, Century 21.
Brokers can also be categorized based on the services they offer:
Full-Service Brokers. They provide personalized advice, financial planning, asset management, banking products, and access to private investments. They typically have higher costs but support the client at every step.
Discount Brokers. They charge lower commissions and cater to traders and investors who manage their own operations. A popular example of this type is eToro.
Online Brokers. These operate exclusively through digital platforms and only execute orders. They are usually chosen by those who already know the market and prefer to trade independently.
Now that you know the types of brokers, the next question is: how can I find a reliable broker?
Check the following recommendations.
To invest with confidence, you need to know how to choose the best broker. However, in the financial world, making this kind of decision isn’t easy. That’s why we’re here to offer some key recommendations:
Today’s financial market is incredibly diverse. From traditional brokers to apps offering currency exchange and access to digital products.
The problem? Not all available options are regulated, which can put your money at risk.
So before trusting any broker with your funds, the first thing you should do is verify their legal status. That means confirming whether they operate under a reliable financial authority, as this ensures they follow standards designed to protect investors.
Make sure that depositing and withdrawing funds is easy and unrestricted. Also, check whether the broker suits your investment needs by reviewing things like:
The type of products offered.
The level of service provided.
Applicable fees.
The minimum deposit required to start trading.
It’s just like comparing banks when exchanging dollars for pesos—you need to evaluate which one works best for your finances.
The broker must offer clear and upfront information about all fees: commissions, spreads, withdrawal charges, or inactivity penalties.
Pro tip: Start with a small amount to test the platform and evaluate its transparency, processing times, and customer support.
Ideally, choose a broker that offers customer support during full market sessions (24 hrs × 5 days). This can be via live chat, phone, or even a personal account manager.
The key is having someone available when you need to resolve issues or emergencies.
Top brokers provide well-structured educational material—from beginner to advanced levels. This may include seminars, webinars, tutorials, or even a full academy to support your development as a trader.
Understanding what a broker is and the different types available is the foundation for making better investment decisions. It helps you choose a reliable broker that fits your profile—making the difference between moving forward with confidence or taking unnecessary risks.
Always evaluate if the broker is regulated, the services offered, tools provided, and the associated costs before taking the first step.
