1. Fidelity — Best Overall and Lowest Costs

Open a Fidelity account to experience the strongest all-around brokerage platform currently available. Fidelity eliminates account minimums, allowing you to start trading with exactly $0. The platform routes your orders to get price improvement, saving you an average of $0.015 per share on large orders. Park your uninvested cash here to automatically earn over 4.90% in their core sweep account.

Use the Active Trader Pro desktop platform to map out complex options strategies and analyze real-time market data. You get access to 45 distinct technical indicators and drawing tools. Fidelity shines by refusing to charge payment for order flow (PFOF) on stock trades. This means they do not sell your order data to high-frequency trading firms. Navigate the mobile app to execute trades on the go, though advanced traders might find the mobile charting slightly basic compared to the massive desktop suite.

Take advantage of their extensive mutual fund network to build a diversified retirement portfolio. Fidelity offers more than 3,700 no-transaction-fee mutual funds. You can also buy fractional shares of popular companies for as little as $1 per slice. Call their customer service team 24 hours a day if you run into technical issues or need help understanding a margin call.

Master the Trader Workstation desktop platform to execute complex algorithmic trades. This software packs a massive amount of data into a single screen.

3. Charles Schwab — Best for Research and Large Selection

Transfer your assets to Charles Schwab to access Wall Street-grade research without paying premium fees. Schwab acquired TD Ameritrade and successfully integrated the powerful thinkorswim trading platform into its core ecosystem. Launch thinkorswim on your desktop to utilize over 400 technical studies and 20 distinct drawing tools for deep chart analysis. Schwab supports your trading journey with 24/7 phone support and a massive network of over 300 physical branch locations.

Utilize the Schwab Stock Slices feature to buy fractional shares of any S&P 500 company for as little as $5 per transaction. You can purchase up to 30 different fractional slices in a single order to balance your equity exposure.

Watch out for the low interest rates paid on uninvested cash balances. The default sweep account pays less than 0.45%, which trails far behind top competitors. You must manually move your idle funds into a purchased money market fund to capture yields above 5.00%. Utilize their proprietary equity ratings to evaluate individual stocks before committing your capital to a new position.

Best for:

4. E-Trade — Best for Options and Web Platform

Set up an E-Trade account to dominate the options market through a highly intuitive web interface. E-Trade operates two distinct mobile applications. You can use the standard app for casual investing or launch the Power E-Trade app for active derivatives trading. Execute complex options strategies using the Power platform’s custom risk-reward sliders and integrated probability calculators. These tools visually map out your maximum profit and loss potential before you submit the order.

Qualify for the active trader pricing tier by executing at least 30 trades per quarter. This volume drops your options contract fee from the standard $0.65 down to $0.50 per contract. E-Trade provides a massive library of educational content and live webinars. This makes it incredibly easy to understand complex options Greeks (Delta, Theta, Gamma) before risking your capital.

Keep in mind that E-Trade operates under the ownership of Morgan Stanley. This brings massive institutional backing and access to exclusive initial public offering (IPO) shares. However, this corporate shift slightly slowed down customer service response times during peak morning market hours. Trade standard stocks and ETFs for exactly $0 commission. You can also open an automated core portfolio account if you deposit a minimum of $500 and pay a 0.30% annual advisory fee.

Best for:
Options traders who want powerful risk analysis tools on both web and mobile.

Skip if:
You want to trade direct international stocks or foreign exchange markets.

Key points:
– Charges $0.50 per options contract for users making 30 quarterly trades.
– Requires $0 minimum deposit to open the standard brokerage account.

5. M1 Finance — Best for Automated Investing

Fund an M1 Finance account to automate your wealth-building strategy using their unique “Pie” system. M1 Finance forces you to think long-term by organizing your portfolio into visual slices. Assign specific percentage weights to up to 100 individual stocks or ETFs. The platform automatically buys fractional shares to maintain your exact target allocation every single time you deposit fresh money.

Choose from over 100 pre-built expert portfolios if you prefer to remain entirely hands-off. You can select target-date retirement pies or income-focused dividend pies. M1 Finance charges a 0% management fee on these accounts, saving you thousands compared to traditional robo-advisors that usually charge 0.25% or more. Utilize their dynamic rebalancing feature to manage risk. This system automatically directs new deposits into your underperforming assets to bring your pie back to its target weights.

Note that M1 restricts trading to just 2 specific time windows per day. The morning window opens at 9:30 AM EST, and the afternoon window opens at 3:00 PM EST for premium members. This structure makes the platform completely useless for day traders looking to scalp quick price movements. You must also deposit an initial $100 to activate a standard taxable account, or $500 to open an individual retirement account (IRA).

Best for:
Passive investors who want to automate dollar-cost averaging into a custom portfolio.

You want to day trade, trade options, or control exact execution times.

6. Ally Invest — Best for Banking Integration

Link your finances through Ally Invest to manage your trading account and high-yield savings from one dashboard. Ally Invest eliminates the friction of moving money. Transfer funds instantly between your Ally Bank checking account and your Ally Invest brokerage account. This bypasses the standard 2-to-3-day ACH settlement period that plagues standalone brokerages.

Trade US stocks and ETFs for $0 commission using their streamlined web platform. The interface loads quickly and avoids overwhelming casual investors with unnecessary data feeds. Ally offers a robo-advisor option alongside its self-directed accounts. This allows you to split your total capital between active stock picking and automated portfolio management. Keep exactly 30% of your robo-portfolio in a cash buffer to waive the 0.30% annual advisory fee completely.

Be aware that Ally Invest lacks physical branch locations and does not offer advanced charting tools. You will not find level 2 market data or complex algorithmic routing options here. This makes the platform better suited for casual investors rather than hardcore technical analysts. Options traders pay a standard $0.65 per contract fee, and the platform does not offer a volume discount tier for hyper-active derivatives traders.

Best for:
Existing Ally Bank customers who want instant fund transfers and all-in-one financial management.

Skip if:
You rely on advanced technical indicators, level 2 data, or physical branch support.

Key points:
– Requires $0 minimum deposit for self-directed trading accounts.
– Executes internal bank-to-brokerage transfers in under 1 minute.
– Charges $0 commission on US stock and ETF transactions.
– Demands a $100 minimum to start the automated robo-portfolio.
– Waives the 0.30% advisory fee if you hold 30% in cash.

7. Merrill Edge — Best for Rewards and Bank of America Customers

Hit the $100,000 balance tier to unlock massive perks. This Platinum Honors tier grants you a 75% bonus on eligible Bank of America credit card rewards and heavily discounted mortgage origination fees. Merrill Edge provides excellent third-party research reports from Morningstar and CFRA. Read these professional analyst reports to gauge the fair value of a stock before executing a trade. Trade standard US stocks and ETFs for exactly $0 commission.

Do not expect to trade futures, direct cryptocurrencies, or fractional shares on this platform. Merrill Edge strictly limits its available asset classes compared to standalone brokerage giants. The platform also lacks a dedicated paper trading simulator for beginners to practice strategies. Use the MarketPro desktop platform to access customizable charting tools and streaming level 1 quotes if you maintain the required minimum balance.

Best for:
High-net-worth individuals who use Bank of America and want to multiply credit card rewards.

You want to buy fractional shares or trade advanced asset classes like futures.

Key points:
