How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Fidelity charges $0 for online OTC trades and takes no payment for order flow, which makes it the default pick for most people.
- Interactive Brokers suits active traders who need routing, order types and low per-share pricing.
- Schwab and E*TRADE charge $6.95 per online OTC trade even though listed stocks are free.
- The tier a stock trades on matters more than the broker: OTCQX and OTCQB companies report; much of Pink does not.

Fidelity is the pick most OTC traders should start with, for one simple reason: it charges nothing. Its $0 online commission covers most OTC securities, and its refusal to take payment for order flow means your order is routed for execution quality rather than for a rebate. StockBrokers.com's 2026 testing rated it the best broker for penny stocks on exactly those grounds.
The research matters as much as the price. OTC trading goes wrong in the diligence, not the order ticket, and Fidelity's screening, filings access and quote detail give you a fighting chance of spotting a shell before you own it. Expect some friction on the riskiest names; Fidelity restricts certain tickers and reviews others, which most readers should read as a feature.
What we like- $0 online commission extends to most OTC securities with a standard ticker, no payment for order flow, so execution is not sold to market makers, deep research, screening and risk controls for small companies, fractional shares from $1 across thousands of securities
Watch out for- Fidelity applies conservative controls and blocks or reviews some risky OTC tickers, foreign ordinary shares that are not DTC eligible carry a $50 transaction fee, Active Trader Pro is powerful but dated next to newer platforms

Interactive Brokers is the professional's route into OTC. IBKR Lite gives casual accounts $0 commissions, while IBKR Pro charges per share, typically fractions of a cent with a $1 minimum per order, which suits large share counts in low-priced stocks better than a flat $6.95. Routing is direct and order types are deep, including the limit and conditional orders thin markets demand.
It also opens the foreign side of OTC: ordinary shares of overseas companies trading under tickers ending in F, which most app brokers do not carry. The trade-off is complexity. Trader Workstation is a serious tool with a serious learning curve, and market data is sold in packages. Active traders accept that; everyone else is happier at Fidelity.
What we like- IBKR Lite offers $0 commissions and IBKR Pro offers per-share pricing that falls with volume, direct market access and professional order routing across many venues, access to foreign OTC shares and global markets few rivals match, among the lowest margin rates in the industry
Watch out for- The platform is complex and data packages cost extra, per-share pricing on tiny-priced stocks needs care (minimums apply per order), customer support is thinner than at Fidelity or Schwab

Schwab is the research-led alternative. thinkorswim gives penny stock traders professional charting, screening and watchlist tools, and Schwab's own research library helps separate real microcap companies from promoted shells. For a considered, occasional OTC purchase, the platform earns its keep.
Know the fee before you trade. Schwab's January 2026 pricing guide lists $6.95 per online OTC trade, unlike its $0 listed-stock commission, and foreign ordinary shares add $50 per transaction. On a small position those charges are a real percentage of the trade, which is why frequent OTC traders usually end up at Fidelity or Interactive Brokers instead.
What we like- Thinkorswim is one of the strongest charting and analysis platforms available to retail traders, extensive research and screening for small-cap diligence, strong customer support and a full-service brokerage behind the account, fractional shares extended to most US stocks in 2026
Watch out for- OTC trades cost $6.95 each online even though listed stocks are $0, foreign OTC trades add a $50 fee on top, some OTC access needs account setup before the first trade

E*TRADE, owned by Morgan Stanley, is the middle path: easier to read than the pro platforms, better researched than the app brokers. Its OTC pricing mirrors Schwab at $6.95 per online trade, with one useful difference: customers making 30 or more trades a quarter pay $4.95, so genuinely active penny stock traders get a partial break.
For the reader who trades OTC occasionally inside a wider portfolio, E*TRADE's balance of research, screening and a calm interface works well. Just do the same maths as at Schwab: on a $200 position, two $6.95 tickets are 7 percent gone before the stock moves, which is one more reason position size and patience matter in this market.
What we like- Clean, beginner-readable platform with solid research from Morgan Stanley, OTC commission drops to $4.95 with 30 or more trades per quarter, good screening and third-party research for small companies, paper trading to practice without real money
Watch out for- $6.95 per OTC trade at the standard tier, platform features trail thinkorswim and Trader Workstation for active traders, some OTC names require setup or are restricted
Starting price$0 per trade

Webull suits the phone-first trader who dabbles. Commissions are $0 and the app is quick, but its OTC shelf is the catch: coverage is partial and changes, so the obscure Pink name you researched may simply not be tradable there. Check availability before funding an account for a specific stock.
The diligence gap is the deeper issue. Webull's research tools are built for listed stocks, and OTC trading lives or dies on filings, tier status and promotion checks that the app does little to surface. Used for the more established OTC names with limit orders set, it is serviceable. Used as a discovery tool for penny stocks, it points the wrong way.
What we like- $0 commissions and a fast, modern mobile app, extended hours trading on listed stocks, clear charts and watchlists for an app broker, no account minimum
Watch out for- OTC coverage is limited and varies by security, research depth is shallow for microcap diligence, margin rates are higher than at Interactive Brokers

SoFi Active Investing
Best for: Simple $0 OTC access for beginners

Starting price$0 per trade
Free planNo
SoFi is the simplest door on this list. Its Active Investing account charges $0, has no minimum, and its OTC policy is more permissive than most app brokers, so a beginner who wants one account for banking and occasional OTC purchases can do it without opening a full brokerage relationship.
Keep the beginner framing honest, though. Simple is not the same as suitable. SoFi gives you little help checking whether an OTC company files reports, who is promoting it, or how thin its market is. If you use it, import your diligence from outside: the SEC's investor bulletins and OTC Markets' own tier pages tell you more than any app summary.
What we like- $0 trades with a permissive OTC policy for an app broker, simple account that sits alongside SoFi banking and other products, no account minimum and fractional shares, educational content aimed at newer investors
Watch out for- Research and screening are light for microcap work, fewer order types and no serious charting platform, limited margin options

TradeZero is the specialist: a broker built around active trading in low-priced stocks, known for short sale locates, hotkey-driven platforms and direct market access. For the small group of experienced traders who trade OTC momentum intraday, it offers tools the generalist brokers do not.
It is listed last on purpose. Shorting penny stocks and day trading promoted names is where retail losses concentrate, and a platform that makes it fast does not make it safer. TradeZero's pricing varies by platform tier and route, so check the current schedule on its site. If you cannot explain how you will manage a halted, gapping penny stock, this broker, and arguably this market, is not for you.
What we like- Built for active penny stock traders with locate access for short selling, hotkeys and direct routing aimed at fast execution, offers zero-commission routes on its paid platform tiers, long-standing specialist in low-priced stocks
Watch out for- Aimed at day traders, which is the highest-risk way to trade this market, platform and data fees apply on the serious tiers, small broker without the research library of the majors
How we chose
Platforms were included only if a US retail customer can open an account and trade OTC securities today. They were judged on OTC commission, breadth of OTC access by market tier, execution model (including payment for order flow), order types suited to thin markets, and the research tools available for checking whether an OTC company actually reports. Brokers that block OTC trading entirely, and offshore brokers outside US regulation, were excluded by design.
What to know before you trade OTC stocks
The market tier is the first fact to check. OTC Markets groups stocks into tiers: OTCQX and OTCQB companies meet reporting and disclosure standards, while Pink market names range from ordinary foreign companies to shells with no current information at all. A platform that shows you the tier and the company's filing status is doing the minimum. Trade names you can verify.
Then respect the mechanics. Spreads in OTC stocks can be 10 percent or more, so a market order can fill far from the last price; use limit orders. Volume can vanish, which means entering is easy and leaving is not. Below $5 with a tiny market value, a stock is a penny stock under SEC rules, and your broker must give you the official penny stock risk disclosure before your first trade. Read it; it describes this market accurately.
Last, the fraud pattern has a shape. A stock nobody mentioned last month is suddenly everywhere, promoted by accounts that never disclose who pays them, with promises of a takeover or a breakthrough. That is the pump. The dump is what happens to the people who bought it. No platform on this page can protect you from a promotion. Only refusing it can.
Frequently asked questions
What is an OTC trading platform?
It is a brokerage account that lets you buy and sell over-the-counter securities: stocks that trade through dealer networks rather than on the NYSE or Nasdaq. Most large US brokers offer it, but commissions, tier access and restrictions differ, which is why Fidelity's $0 OTC trades and Schwab's $6.95 fee matter.
Why do some brokers charge for OTC trades when stocks are free?
OTC orders are harder and costlier to route and clear than exchange orders, and several brokers keep a per-trade fee for them. Fidelity and IBKR Lite charge $0 for most OTC trades; Schwab and ETRADE charge $6.95, with ETRADE dropping to $4.95 for very active accounts. Foreign ordinary shares often add a separate fee everywhere.
Are penny stocks a good way to make money?
For most people, no. Penny stocks are thinly traded, lightly reported and the most fraud-prone corner of the US market, and the SEC warns that investors lose money in them at high rates. Some OTC companies are legitimate small businesses, but finding them takes filing-level research, and position sizes should assume the money can be lost entirely.
What is the difference between OTCQX, OTCQB and Pink?
They are disclosure tiers run by OTC Markets. OTCQX companies meet the highest financial and reporting standards of the three. OTCQB companies report and pass a minimum bid test. Pink is the broadest and riskiest tier, including companies that disclose little or nothing current. The tier tells you how much verified information exists before you risk money.
Can I short sell OTC stocks?
Sometimes, at brokers that can locate shares, such as TradeZero and Interactive Brokers. It is expensive and dangerous: borrows are scarce, fees are high, and a thin stock can jump against you faster than you can exit. Beginners should not short OTC stocks at all.
