Best Online Brokers and Trading Platforms

Fidelity sits at the top of this list of the best online brokers and trading platforms. It is also the clearest example of why the ranking can’t be read from the fee columns alone. All seven brokers here charge $0 for online stock trades, so the stock commission tells you nothing about which one suits you. The real differences sit elsewhere:

• what each broker charges per options contract
• whether it requires a deposit to open
• whether it offers crypto and fractional shares
• the parts of the cost structure that never appear in a headline fee: payment for order flow, interest paid on idle cash, margin rates, fund fees and withdrawal charges

The order runs Fidelity, Charles Schwab, Robinhood, Vanguard, SoFi, eToro and Ally. That order is not a sort by price. Ally charges less per options contract than Fidelity or Schwab. SoFi, eToro and Robinhood charge $0 per contract for options, yet Vanguard, at $1 per contract, ranks above three of them. A broker’s position reflects more than its fee schedule. A lower-ranked broker can still be the better choice for a specific need: a trader who only buys and sells options on stocks, for example, or a long-term fund investor who never touches options at all.

How to Read This Ranking

Five measures can be compared directly for each broker: minimum deposit, stock trade cost, per-contract options fee, fractional shares and crypto. Three of them barely separate the field. All seven brokers charge $0 for stock trades, fractional shares are widely offered, and five of seven offer crypto. The separation comes from options pricing, minimums and the few gaps in fractional and crypto support.

The fields also differ in how much they matter to you:

• Per-contract options fee. This is the most visible cost difference between the brokers. It only matters if you trade options. A buy-and-hold investor in index funds will never pay it, so a $0 or $1 figure makes no difference to that person.
• Minimum deposit. Six brokers require no deposit to open (SoFi advertises “$0 to open”), and eToro requires $50. A $50 minimum is no barrier for most new accounts. It matters only if you want to open an account and fund it later, or test a platform with a few dollars.
• Fractional shares. Fractional trading lets you buy part of a share, so a $25 order can go into a stock trading at several hundred dollars. Six brokers on the list offer it. If you plan to build positions in fractional amounts at Ally, confirm with Ally that it supports them before opening an account.
• Crypto. Ally does not offer crypto, and Vanguard has not positioned itself as a crypto broker. If you want crypto alongside stocks in one login, that leaves five options here. How crypto is offered also varies by broker, and that affects protection (see the safety section below).

Two things a fee schedule cannot show also drive real cost. The first is execution quality: whether your order fills at a better or worse price than the quoted market. The second is how a broker treats the cash you aren’t investing. The broker profiles below cover both where the brokers differ on them.

Where the Seven Brokers Differ

Each profile focuses on what separates that broker from the others on the list.

Fidelity

Fidelity has a $0 account minimum, $0 stock trades and $0.65 per options contract. Schwab charges exactly the same three amounts, so Fidelity’s place at the top rests on what it adds beyond the headline schedule.

It does not accept payment for order flow. Payment for order flow (PFOF) is the practice of a broker routing customer orders to a market maker that pays the broker for that flow. It is legal and widespread among commission-free brokers. Critics argue it creates a conflict of interest: the broker earns money from where it sends your order, not only from how well that order is filled. Fidelity declines PFOF for stock trades. That removes one source of conflict, though execution quality still depends on how orders are routed and filled.

Breadth of investments. Fidelity offers U.S. and international stocks, several types of bonds, ETFs, physical metals and more than 10,000 mutual funds from Fidelity and other fund companies, many with no transaction fee. Fractional share trading covers stocks and ETFs, which matters for anyone building a diversified portfolio with small monthly contributions.

Tools for investors rather than just traders. Fidelity has customizable screeners for stocks, ETFs, mutual funds and fixed income, along with portfolio analysis tools. It also offers direct indexing, which builds a customized index-like portfolio from individual stocks so the investor can manage tax efficiency and exposure position by position.

The limits. Fidelity charges fees on certain non-Fidelity mutual funds, so “more than 10,000 funds” does not mean 10,000 free funds. It does not offer futures. Its crypto offering covers only a small number of coins. Its commissions on multi-leg options trades are less competitive than at brokers built around options.

Small charges inside “$0.” Zero-commission trades at Fidelity still carry pass-through charges. Sell orders are subject to an activity assessment fee, which has historically run from $0.01 to $0.03 per $1,000 of principal. A limited number of ETFs carry a transaction-based service fee. These charges are small, and they apply on top of the $0 commission.

Crypto is a separate entity. Fidelity Crypto is provided by Fidelity Digital Assets, a limited-purpose trust company chartered by the New York State Department of Financial Services. The brokerage arm does not hold the crypto. Crypto held there is not covered by SIPC or FDIC protection. That is the same position crypto holders face at most brokers, but here the separation is written into the account structure.

Fidelity was founded in 1946 by Edward C. Johnson and is headquartered in Boston. It operates more than 200 investor centers, which matters to investors who want an in-person branch alongside the online platform.

Charles Schwab

Schwab matches Fidelity on all three headline figures: $0 minimum, $0 stock trades, $0.65 per options contract. It also offers fractional shares and crypto. The differences between the two leaders lie in platforms, education and how cash is treated.

thinkorswim. Schwab acquired TD Ameritrade in a deal announced in 2020 and completed client integration in mid-2024. That brought thinkorswim, TD Ameritrade’s well-regarded active trading platform, into Schwab’s lineup. thinkorswim offers detailed charting, trading analytics, multiple order types and real-time paper trading. Paper trading means placing simulated orders with virtual money against live market data, a way to learn order entry and test a strategy without risking capital. Schwab therefore runs two tracks: the standard Schwab.com and app experience for investors, and thinkorswim (desktop, web and mobile) for active traders.

Education. Schwab’s learning materials span articles, regularly scheduled coaching videos and live training events at individual branches. Pairing structured education with a paper-trading-capable platform is a practical route for a beginner who plans to move into options or more active trading later.

Mobile. Schwab’s app gives mobile access to stock screeners, charting and conditional orders. A conditional order is one that triggers only when a set condition is met, such as a price level or the fill of another order. A mobile version of thinkorswim covers more advanced workflows. Schwab also offers an AI assistant inside the app for navigation and general questions.

Forex access. Through thinkorswim, Schwab offers spot forex trading. Its forex costs come from spreads and overnight financing rather than a separate commission. Forex trading is not available to residents of Ohio and Arizona. If currency pairs are your main interest, a dedicated forex broker comparison such as our best forex brokers ratings covers that market in more depth.

The weaknesses are cash and margin. Schwab’s margin rates are comparatively high. The interest it pays on uninvested cash is low unless you move that cash into a money market fund or similar product yourself. For an investor holding a few thousand dollars in cash between purchases, the gap between a low sweep rate and a money market fund yield can exceed a year’s worth of options commissions. Schwab’s fractional share trading covers stocks but not ETFs.

Schwab began in April 1971 as First Commander Corporation and took the Charles Schwab & Co. name in 1973. It is now one of the largest U.S. brokers by assets.

Robinhood

Robinhood has a $0 minimum, $0 stock trades and $0 for stock and ETF options. That last figure is worded precisely. Options on individual stocks and ETFs carry no per-contract fee, but index options are priced separately with a per-contract fee. Futures also carry their own charges. Members of Robinhood Gold, the broker’s paid monthly subscription, pay lower fees on index options and futures. Gold also adds research, data and interest on uninvested cash.

How the costs work. Robinhood’s no-commission model made $0 stock and ETF trades the industry norm. Its revenue model relies more heavily on payment for order flow than Fidelity’s. The two brokers’ identical “$0 stock trades” are therefore not equivalent in how each earns money from your orders. Robinhood’s overall fee structure is competitive but layered: different rules for standard options, index options, futures, crypto and Gold members.

Crypto. Robinhood offers crypto trading alongside stocks and provides a Web3 wallet that lets customers move crypto in and out without transfer fees. Not every broker that offers crypto allows transfers to an outside wallet. Some only let you buy, hold and sell inside the account. If you want to move coins to self-custody, that difference matters more than the number of coins listed. Crypto availability can vary across Robinhood’s platforms and by state.

Platforms. Robinhood began as a mobile app. It launched Robinhood Legend, a desktop trading platform, in October 2024 to serve more active traders. It also offers 24-hour trading in certain stocks five days a week.

What it lacks. Robinhood does not offer forex, mutual funds or fixed income, and its research is limited compared with the brokers above it. It now offers retirement accounts, but you need an individual account before you can open an IRA.

Robinhood was founded in 2013 by Vlad Tenev and Baiju Bhatt, who met as Stanford University roommates. It initially offered only individual taxable accounts.

Vanguard

Vanguard charges $0 for stock trades and $1 per options contract. Opening a brokerage account is one question; buying Vanguard mutual funds is another, because many of those funds carry their own minimum initial investment. For an investor who plans to start with a single fund purchase, the fund minimum is the number that matters.

Built for buy-and-hold. Vanguard does not compete on active trading tools. It focuses on long-term investing, especially through index funds and ETFs, and its platform is intentionally plain. The $1 options fee is the highest per-contract figure on this list, and for a long-term fund investor it is irrelevant. For an options trader it is a reason to look elsewhere.

Low-cost funds and cash. Vanguard was established in 1975 in Valley Forge, Pennsylvania, and launched the first index fund available to individual investors in 1976. The company is owned by its funds, which in turn are owned by their shareholders. That structure underpins its low-cost positioning. Vanguard also pays competitive interest on cash balances. For long-term investors, the expense ratio on the funds they hold for decades usually costs more than any trading fee they will pay.

An example of that point, with assumed figures: on a $100,000 portfolio, an expense ratio of 0.05% costs $50 a year, while 0.50% costs $500 a year. The gap repeats every year and compounds through lost growth. Assumptions: constant balance, no growth, fees calculated on the year-end balance.

The drawbacks. Vanguard charges high withdrawal fees on some fund transactions. It requires a 60-day holding period on initial cash and check deposits. Its mobile app supports trading only in stocks, ETFs and Vanguard mutual funds.

SoFi

SoFi has “$0 to open,” $0 stock trades and $0 options per contract, and it offers both fractional shares and crypto. On those measures, SoFi matches or undercuts every broker on the list.

The wording “$0 to open” is worth reading literally. It describes the opening requirement for the account, not a promise that every product inside it has no minimum. SoFi’s position below Robinhood and Vanguard, despite headline fees that match or beat theirs, is another sign that this ranking weighs more than the fee columns. Before choosing SoFi on cost alone, compare the factors in the “How to Choose” section below, particularly research depth, order types and how idle cash is treated.

eToro

eToro has a $50 account minimum, $0 stock trades and $0 options per contract. It is the only broker on the list that requires a deposit to open.

Social trading is the core difference. eToro’s CopyTrader feature lets you automatically replicate the trades of other investors in real time. Before following someone, you can review their performance history, risk score and portfolio allocation, and you can start or stop copying at any time. Smart Portfolios bundle themes or groups of stocks into an automated allocation. A built-in social feed lets users share, discuss and react to trades.

Copying a trader means taking on their risk at your scale. A past performance record does not predict future results. A trader with a strong record built on high-risk positions can lose quickly, and a copied account follows those losses. Treat the risk score and the drawdown history as more informative than the headline return.

Crypto has its own fee. Crypto trades on eToro carry a percentage fee rather than a flat commission. The cost therefore scales with trade size: a fee that is trivial on a $100 buy is not trivial on a $10,000 one. eToro’s U.S. crypto list was cut back to bitcoin, bitcoin cash and ether following a 2024 settlement with the SEC, and the selection has since expanded again.

Other costs. eToro has no withdrawal fee but sets a minimum withdrawal amount. Currency conversion fees can apply when money moves between currencies. In the U.S., forex and CFD trading are not offered and margin trading is not available. U.S. accounts also have a narrower asset list than eToro’s global offering, and the platform has relatively few advanced trading tools.

eToro was founded in 2007 and is based in Tel Aviv, Israel. It operates globally with a community of millions of users. Its strongest case is for newer investors who want to learn by watching how others allocate, not for traders who need deep charting or complex order types.

Ally

Ally has a $0 minimum, $0 stock trades and $0.50 per options contract. It does not offer crypto, so Ally and Vanguard are the two brokers here without it.

For an options trader choosing among brokers that charge a per-contract fee, Ally’s $0.50 is lower than Fidelity’s and Schwab’s $0.65 and Vanguard’s $1. It is still higher than the $0 charged by Robinhood (for stock and ETF options), SoFi and eToro. The decision comes down to whether a per-contract fee is worth paying for Ally’s platform and its place in a wider banking relationship, compared with $0 options at a broker that may fall short elsewhere.

When a Broker Outside This List Fits Better

The seven brokers above cover most self-directed U.S. investors. A few needs push readers toward firms that are not on this list. Interactive Brokers is the most common alternative, and several of its competitors serve narrow needs well.

International markets: Interactive Brokers. Interactive Brokers (IBKR) offers access to 170 markets across 40 countries and 29 currencies, with stocks, funds, bonds, futures, options, forex and crypto on one platform. Most U.S. online brokers offer no direct international trading at all. If you want to buy shares on a foreign exchange in its local currency, rather than through a U.S.-listed ADR or ETF, IBKR is the reference point.

IBKR has two pricing plans. Lite charges $0 commissions on U.S.-listed stocks and ETFs. Pro uses tiered pricing that falls as trading volume rises. Options cost $0.65 per contract on both plans, with Pro scaled by volume. IBKR is known for low margin rates, competitive interest on unused cash, algorithmic order types, APIs and real-time margin monitoring. Its Trader Workstation (TWS) platform has a steep learning curve; IBKR Desktop is the more approachable alternative. Backtesting is only available through the API and third-party tools. IBKR offers limited access to IPOs and OTC stocks. The firm was founded in 1977 by Thomas Peterffy and is headquartered in Greenwich, Connecticut.

Heavy options trading: tastytrade. tastytrade charges $1 per options contract with a cap of $10 per leg, and no commission to close options positions. For a trader who opens large positions, the cap matters. Under that cap, opening 50 contracts in a single leg costs $10 rather than $50. Assumptions: one leg, opening trade, regulatory and clearing fees excluded. The platform is built around options analytics and connects to tastylive programming. It does not offer on-platform paper trading or mutual funds. It launched as tastyworks in 2017, rebranded in 2023 and is based in Chicago.

Screening: E*TRADE. E*TRADE, owned by Morgan Stanley since a $13 billion acquisition in 2020, offers custom and predefined screeners for stocks, ETFs, mutual funds and options on its Power E*TRADE platforms. It charges $0.65 per options contract, reduced to $0.50 for customers who make at least 30 options trades a quarter, and $1.50 per contract, per side, for futures. “Per side” means you pay on both the opening and the closing trade, so a round trip costs $3.00 per contract before exchange and regulatory fees. Fractional ETFs are only available through its robo-advisor or dividend reinvestment. E*TRADE was founded in 1982 and was one of the first brokers to offer trading over the internet.

Futures. Fidelity does not offer futures. Robinhood and Schwab do, but futures traders weigh margin requirements, platform speed and per-contract fees differently from stock investors. Our futures trading platforms ranking covers that market specifically.

Research depth: Merrill. Merrill Edge charges $0 for stock and ETF trades and $0.65 per options contract. It gives customers access to Bank of America Global Research and integrates with Bank of America banking. It does not offer futures, crypto or fractional shares.

How to Choose an Online Broker

No ranking can account for your goals, account size and trading frequency. The factors below are the ones that change which broker is cheapest or most useful for a particular person.

Start With How You Will Use the Account

Investing usually means buying assets to hold for years toward goals such as retirement. Trading means shorter-term positions held for days, hours or minutes, with more frequent orders and generally more risk. The two uses reward different broker features.

A long-term investor making a monthly contribution to a few index funds needs low fund costs, fractional shares or low fund minimums, automatic investing, retirement account options and decent interest on cash. Options pricing, charting and order types barely matter.

An active trader needs the opposite: fast and reliable execution, advanced order types, real-time data, a capable desktop platform, low per-contract fees and reasonable margin rates. Fund selection and in-person branches barely matter.

Most people sit between these poles. Decide which of your activities will generate the most transactions. That activity’s cost structure should drive your choice.

Day Trading and the Pattern Day Trader Rule

Anyone who plans to day trade U.S. stocks needs to know FINRA’s pattern day trader rule. A customer who executes four or more day trades within five business days in a margin account, where those trades make up more than 6% of total trades in that period, is classified as a pattern day trader. A day trade means buying and selling, or selling short and buying back, the same security on the same day. A pattern day trader must keep at least $25,000 in equity in the margin account. Below that level, day trading is restricted until the balance is restored.

The rule applies to margin accounts across all U.S. broker-dealers, so switching brokers will not get around it. Some traders use a cash account instead. A cash account isn’t subject to the pattern day trader rule, but you can only trade with settled funds. Since U.S. stock trades moved to T+1 settlement in May 2024 (the trade settles one business day after execution), proceeds from a sale become usable for a new purchase sooner than under the old two-day cycle. Buying and then selling a stock with unsettled funds in a cash account can still trigger a good-faith violation.

Commissions and Fees Beyond the Headline

With $0 stock commissions now standard, the cost comparison between brokers lies elsewhere.

Options per-contract fees. These add up with volume. An example with assumed figures: a trader who opens and closes 20 option contracts a month makes 40 contract transactions. At $0.65 per contract that is $26 a month, or $312 a year. At $0.50 it is $20 a month, or $240 a year. At $0 the commission is zero. Assumptions: the fee applies on both opening and closing trades, and regulatory and exchange fees are excluded. A broker that waives the fee on closing trades, as tastytrade does, would halve the count. Fee schedules differ on whether closing trades are charged, so check this before multiplying.

Multi-leg strategies. A spread with four legs means four contracts per unit, so per-contract pricing applies to each leg. Brokers that cap fees per leg or per order change that math for large positions.

Regulatory pass-through fees. U.S. sell orders carry a small SEC fee under Section 31 of the Securities Exchange Act and a FINRA trading activity fee. Options trades carry an options regulatory fee. Brokers pass these through even on “$0 commission” trades. They are small per trade, but they are not zero.

Payment for order flow and execution quality. A broker paid for routing your order has a reason to send it where it earns the most. You may still get a fair price, and some studies find price improvement on PFOF-routed orders. But a fraction of a cent per share on execution can outweigh a commission for someone trading large share counts. U.S. brokers publish order routing reports under SEC Rule 606, which show where orders go and what payments the broker receives.

Margin rates. If you borrow to buy securities or to sell short, the margin rate is a recurring cost that can exceed every other fee combined. Rates vary widely between brokers and usually tier down as the loan balance grows.

Cash interest. Uninvested cash is often swept into a bank deposit program or money market fund. Some brokers pay low sweep rates by default; others pay competitive rates or make a money market fund the default. On a meaningful cash balance, this gap can be larger than your annual trading costs.

Account-level fees. Look for transfer-out fees (moving an account to another broker through ACATS often carries a charge), wire fees, paper statement fees, fund transaction fees on outside mutual funds, and short-term redemption fees. None of these show in a commission column.

Available Assets and Account Types

Check that the broker offers every asset you expect to hold, not just the ones you hold today. Most online brokers offer stocks, ETFs and options. Fewer offer futures, international stocks, bonds or a broad mutual fund supermarket. Crypto availability varies widely; five of the seven brokers on this list offer it.

Account types matter just as much. Most brokers offer individual and joint taxable accounts plus traditional and Roth IRAs. Look for the less common types too, if you need them: custodial accounts for minors, trust accounts, SEP or SIMPLE IRAs for self-employed people, and health savings accounts. Moving an account later is possible but takes time and may carry fees. Choosing a broker that covers your likely needs saves a transfer.

Watch for assets that are listed but restricted. Some brokers offer crypto only in certain states. Some offer forex but not to residents of particular states. Some offer fractional shares for stocks but not ETFs, or only for selected tickers.

Platform and User Experience

A clean, well-built app helps beginners avoid order entry mistakes and makes it easier to stick to a routine. Advanced platforms pack in more charting, order types and scanning, with a steeper learning curve.

Order types are a practical test. A market order fills at the best available price, which can differ from the last quote in a fast market. A limit order fills only at your price or better. A stop order turns into a market order once the stop price is reached, so the fill price can be worse than the trigger price in a gap. A stop-limit order turns into a limit order at the trigger, which protects the price but may not fill at all. Active traders should confirm that the platform supports the order types they rely on, including conditional and bracket orders, on mobile as well as desktop.

If you want to practice before risking money, check whether the broker offers paper trading. A standalone stock market simulator also lets you rehearse order entry and position sizing without opening any account.

Research and Educational Content

Research covers market data, analyst ratings, screeners, charting, company financials and third-party reports. A screener filters thousands of securities down to those that meet your criteria, such as valuation, dividend yield, sector or technical signals. If you pick individual stocks, a good screener saves more time than almost any other tool. If you buy index funds, you need fund research: expense ratios, holdings and tracking.

Educational content ranges from articles and videos to webinars and in-person events. Its value depends on your stage. Beginners benefit from structured courses and plain explanations of account types and order mechanics. More experienced traders benefit from options-specific and strategy content. Charting basics, including indicators such as the Relative Strength Index, are covered free in many places, so a broker’s education is most useful when it is tied to its own platform and order workflow.

Minimums, Fractional Shares and Small Balances

Most brokers on this list let you open an account with no deposit; eToro requires $50. A zero minimum means you can start with any amount. Fractional shares make that practical: with $50 you can buy part of a high-priced stock or ETF instead of waiting until you can afford a full share.

For small accounts, diversification usually matters more than stock selection. A single broad-market ETF bought in fractional amounts gives exposure to hundreds or thousands of companies. Regular contributions, even small ones, do more for a growing account than trying to time purchases.

Check whether automatic investing works with fractional shares. Some brokers let you schedule recurring dollar-amount purchases of ETFs or stocks. Others limit recurring purchases to mutual funds or to a curated list.

Safety: What Protects Your Account

U.S. brokers that hold customer securities are registered with the SEC and are FINRA members. You can look up a broker and its registered representatives on FINRA’s BrokerCheck.

Most are also members of the Securities Investor Protection Corporation (SIPC). SIPC protects customers if a member broker fails and customer assets are missing, up to $500,000 per customer per capacity, including up to $250,000 for cash. SIPC does not protect against market losses. If your stock falls 40%, SIPC pays nothing. Many large brokers carry additional “excess SIPC” insurance through private insurers.

Cash swept into a bank deposit program may be covered by FDIC insurance at the program banks instead of SIPC, up to FDIC limits per bank. Money market funds are securities, not bank deposits, so they carry no FDIC coverage. Crypto held at a broker is generally covered by neither SIPC nor the FDIC, and it is often held by a separate affiliated company, as at Fidelity.

Platform security also matters. Use two-factor authentication, and check whether the broker offers trusted contact designations and alerts for logins and withdrawals.

Online Broker vs. Full-Service Broker

An online broker is built for self-directed investors. You choose the investments, place the orders and manage the account yourself, using the broker’s platform, research and tools. A full-service broker assigns you an advisor who handles more of that work. It typically offers financial planning, retirement and estate planning, insurance and tax coordination alongside investment management.

The cost models differ. Online brokers compete on low or zero commissions, low minimums and free access to research. Full-service firms usually charge an advisory fee as a percentage of assets under management, or commissions on products, in exchange for personal advice. They often require large minimums for advisory accounts.

The line between the two has blurred. Large online brokers such as Fidelity, Schwab and Vanguard now offer advisors, financial planning and robo-advisors alongside self-directed accounts. Full-service firms run low-cost online platforms, as Merrill does with Merrill Edge. You can often hold a self-directed account and a managed account at the same firm.

How a Brokerage Account Works

A brokerage account holds investments the way a bank account holds cash. Money moves in and out in a similar way, but the purpose is buying and holding securities.

1. Apply. You provide your legal name, address, date of birth, Social Security number, employment information and financial details. Brokers are required to verify customer identity. They also ask about income, net worth and investing experience to determine suitability, especially before approving options or margin trading.
2. Choose the account type and features. Decide between a taxable account and an IRA, and between a cash account and a margin account. Options trading usually requires a separate application with approval levels. Higher levels allow more complex strategies.
3. Fund it. Most people link a bank account and transfer money electronically. You can also move an existing brokerage account in kind through ACATS, which transfers your holdings without selling them.
4. Invest. Your available cash appears as buying power. You place orders on the platform, and purchased securities appear as holdings.
5. Settle and withdraw. U.S. stock trades settle one business day after execution (T+1). After a sale settles, you can reinvest the proceeds or withdraw them to your bank. Some brokers hold initial deposits for a period before they can be withdrawn, such as Vanguard’s 60-day hold on initial cash and check deposits.

Taxable accounts generate tax reporting: brokers issue Form 1099 for dividends, interest and realized gains. IRAs defer or eliminate tax on growth, depending on the type, but restrict withdrawals before retirement age.
