Why Are These Brokers the Best for Stock Trading?
Here is a quick overview of why we think these are the best stock brokers:
- Interactive Brokers is the best stock broker for day trading in 2026 4.3/5 IBKR provides access to an unparalleled array of equity products originating from 24 diverse countries. Whether seeking capital appreciation, dividends, or voting rights, you can directly invest in stocks. Alternatively, you can engage in speculative trading on price movements through CFDs, futures and more than 13,000 ETFs. IBKR also enhanced its European equity derivatives offering in 2024 by adding trading on CBOE Europe Derivatives (CEDX).
- NinjaTrader 4.5/5 Stocks can be traded by connecting the NinjaTrader platform to supporting brokers. The firm also provides access to a range of index futures via standard and micro contracts, including the E-Mini S&P 500 Index Futures and E-Mini Russell 2000 Index Futures.
- eToro USA 3.4/5 You can trade 3000+ popular US stocks and ETFs at eToro US, with zero commissions and fractional shares available. The broker remains an excellent choice for beginner stock traders, thanks to its comprehensive eToro Academy and user-friendly stock market research features.
- FOREX.com 4.3/5 FOREX.com provides access to a wide array of US, EU, and UK stock CFDs, featuring spreads as narrow as 1 point. This enables you to speculate on established household names and emerging IPOs, fostering ample opportunities for diversification within stock portfolios. US stocks are accessible from as low as 1.8 cents per share.
- Plexytrade 3.9/5 Plexytrade's range of 48 US stock CFDs trails most competitors, though the selection of 15 popular global indices (including S&P 500, Nasdaq 100, and Dow Jones) is reasonable. Still, the lack of stock market research tools like stock screeners and the minimum deposit requirement to access the economic calendar (a typically free feature at other stock brokers) is disappointing.
- TradeUp 3.5/5 In our tests across mobile, web and desktop, TradeUP delivered a strong stock-trading experience with basic market/limit/stop/stop-limit orders, 22 core indicators and 30+ drawing tools, reliable quotes/fills, and clean confirmations. Beyond mainstream U.S. equities, access extends to selected OTC names and 250+ Chinese ADRs (e.g., BABA, BIDU, NIO).

- The new IBKR Desktop platform takes the best of TWS while adding bespoke tools like Option Lattice and Screeners with MultiSort to create a genuinely impressive trading experience for day traders at every level.
- While primarily geared towards experienced traders, IBKR has made moves to broaden its appeal in recent years, reducing its minimum deposit from $10,000 to $0.
Cons

- Support can be slow and frustrating based on tests, so you might find it challenging to reach customer service representatives promptly or encounter delays in resolving issues.
- You can only have one active session per account, so you can’t have your desktop program and mobile app running simultaneously, making for a sometimes frustrating trading experience.

Pros
- NinjaTrader launched CME Group Single Stock futures in July 2026, allowing traders to express directional views in top U.S. companies like Nvidia, and Amazon without needing options

- NinjaTrader's ecosystem gives traders access to thousands of add-ons and applications from developers across more than 150 countries, covering indicators, strategies, and custom tools that go well beyond what the platform ships with natively
Cons
- Intraday margin requirements can spike by as much as four times in the 15 minutes leading up to major economic news releases, and may stay elevated for several minutes after volatility subsides — a detail that can catch underprepared traders off guard at exactly the wrong moment.
- NinjaTrader was acquired by Kraken in May 2025, and while it continues to operate independently for now, traders who value long-term stability may have reservations about how the platform's direction and pricing could shift under new ownership.
- NinjaTrader was fined $250k in 2025 for failing to implement an adequate anti-money laundering (AML) program and for supervisory failures.

Why Trade Stocks With Plexytrade?
Plexytrade is a newcomer in the brokerage scene with attention-grabbing features like 1:2000 leverage, zero spreads on select instruments and fast execution speeds of less than 46 milliseconds.

- Plexytrade lacks regulation in major jurisdictions, significantly increasing the risks of opening an account and depositing funds.
- With around 100 instruments, Plexytrade restricts the flexibility of investors who prefer to trade across various assets, especially compared to Blackbull with its 26,000 securities.

How Did DayTrading.com Choose The Best Brokers For Day Trading Stocks?
We exhaustively evaluated each stock broker, assigning them an overall rating that served as the basis for our platform rankings. This rating is a culmination of:
- Quantitative metrics: We scrutinized over 200 data points across 8 core categories, carefully documented by our experts.
- Qualitative insights: Our extensive testing process yielded valuable observations that further informed our evaluation.
Below are the key considerations that shaped our stock broker ratings. We recommend you take these factors into account when choosing an online stock broker.
Regulation and Trust
We prioritized online stock brokers that are authorized by trusted financial regulators like the US Securities & Exchange Commission (SEC), UK Financial Conduct Authority (FCA), and Australian Securities & Investments Commission (ASIC).
That’s because top-tier regulators ensure stock brokerages provide measures that can help protect your capital from business failure. The UK’s Financial Services Compensation Scheme (FSCS), for example, protects investments up to £85,000.
Leading regulators also enforce restrictions on leveraged stock trading for retail investors, typically set at 1:5. Leveraged trading is particularly common among short-term traders and it’s regulated to curb potential losses, offering protection in case the stock markets move against you.
- Plus500 maintains its position as one of the most heavily regulated stock brokers (via CFDs) we’ve tested with real money, earning our trust with 7 licenses and a listing on the London Stock Exchange.
Stock Trading Fees
We chose brokers that offer low stock trading and non-trading fees, taking into account commissions on popular shares, margin fees, plus any deposit/withdrawal and inactivity charges.
Picking a brokerage account with low trading fees is especially important if you are day trading stocks, as a large volume of transaction fees can cut into profit margins.
- XTB continues to stand out for its low stock trading fees after introducing zero commissions on shares and charging a competitive 0.5% conversion fee. It’s also one of a limited number of stock brokers we’ve tested to offer high interest on uninvested cash (up to 4.9%).
Stock Market Access
We favored brokers with access to a wide range of stock exchanges, providing short-term trading opportunities across a selection of markets and industries.
Importantly, stock market trading is centralized, meaning that shares in most large companies are sold through national exchanges, such as the New York Stock Exchange (NYSE), National Association of Securities Dealers Automated Quotations (NASDAQ), and London Stock Exchange (LSE).
Companies will not be listed on all exchanges, therefore, you should look for a broker with a global reach, especially if you want to build a diverse portfolio.
Also, some brokers specialize in buying and selling company shares directly, while others only allow you to speculate on stocks as the underlying assets using products like CFDs. These derivatives can be an excellent option for day traders looking for leveraged vehicles to profit from shorter-term price movements.
- Year after year, we’ve been impressed with CMC Markets, which offers an almost unrivalled suite of 10,000+ shares including major stocks in technology, banking, finance, plus consumer and retail sectors.
Stock Trading Platforms and Apps
We selected brokers with excellent stock trading platforms and apps that have clearly been designed with ease of use in mind for beginner traders, alongside helpful stock screeners and sophisticated analysis tools for advanced investors.
That’s because a user-friendly platform ensures smooth navigation, timely execution of trades, and provides valuable tools and insights to inform stock trading decisions.
- eToro’s stock trading platform and app stood out during testing for its simple interface that will appeal to new traders. It also provides intuitive charting and in-built indicators that will serve day traders, as well as integrated research and news feeds, trading calendars and expert commentary.
What Is A Stock Broker?
An online stock broker allows you to purchase company stocks and shares, or trade related derivatives like CFDs, via a website, desktop platform or mobile app, using just the internet.
These brokers will have connections to the stock market and will purchase the stock on your behalf. Trades can be executed at the click of a button, in real-time via their online platforms.
How Do Stock Brokers Make Money?
Stock brokers make money through several avenues. Often you will pay a commission, which is a flat fee per transaction. That said, we’re increasingly seeing online stock brokers, such as XTB, move to commission-free models.
In these instances, stock brokers may make money through a markup on the spread, which is the difference between the price a buyer is willing to pay (bid) and the price a seller is willing to accept (ask) for a particular stock, representing the transaction cost and liquidity in the market.
Some stock brokers are also market makers meaning they create liquidity by taking the other side of your trade. Sometimes, brokers can make money this way if a stock trader makes a loss.
How Do I Start Trading Stocks?
The first step is to open an account with a stock brokerage.
You will find a wide assortment of online stock brokers and trading platforms available online, but choosing the best one for you depends on the stocks you want to trade, your trading strategy and your personal preferences.
You will then need to deposit the minimum amount, which typically ranges from $0 to $500. We’ve learned that depositing more upfront can often provide access to better quality stock trading tools and market research.
After that, you can log into the stock trading platform or app to find opportunities and place trades.
If you are new to stock trading, I recommend starting with a demo account. They simulate real-life market conditions, but any orders placed are with ‘paper money’. This means you can explore a platform and practice day trading stocks before risking real money.
Michael MacKenzieAuthorFAQ
Are Online Stock Brokers Safe?
The best way to stay safe is to choose a trustworthy stock broker. The most reliable sign of a trustworthy stock broker is authorization from one or more respected regulators, such as the SEC in the US, the ASIC in Australia, the FCA in the UK, or the CySEC in Europe.
We regularly verify the licenses of our recommended stock brokers on the respective regulator’s database to ensure they are authorized by the financial bodies they claim to be.
Our team is also comprised of industry experts who keep abreast of major security incidents and unfair trading practices – marking such stock brokerages down where appropriate. This was the case with Robinhood when its trading practices were found to be harmful to retail investors.
