Commissions & Fees

Rank: 1st (of 16)

Interactive Brokers offers two primary pricing plans: IBKR Pro (professionals) and IBKR Lite (casual investors). Because Interactive Brokers’ core clientele are professional traders and institutional investors (e.g., hedge funds), it is crucial to provide the lowest commissions schedule available. In our rigorous assessment, there is no question Interactive Brokers delivers.

IBKR Pro Stock trades: Standard fixed pricing US stock trades run $.005 per share with a minimum of $1.00 and a maximum of 0.5% of trade value. For small order sizes, i.e., several hundred shares, Interactive Brokers is a fantastic deal. However, trade several thousand shares or more, and Interactive Brokers quickly becomes pricey. For example, IBKR Pro is not a good choice for trading penny stocks.

IBKR Pro Options trades: Contract price less greater than $.10 = $.65 per contract with a $1.00 minimum and no maximum. Contract price less than $.10 but greater than $.05 = $.50 per contract with a $1.00 minimum and no maximum. Contract price less than $.05 = $.25 per contract with a $1.00 minimum and no maximum.

IBKR Pro Other benefits: Interactive Brokers does not accept payment for order flow, a key element in providing quality order execution. Also, Interactive Brokers leads the industry with the lowest margin rates, which vary from 1.55% down to a staggering 0.75% for clients who hold more than $1 million with the brokerage.

IBKR Pro Misc Fees: New and casual investors should be aware of the miscellaneous fees and minimums charged by Interactive Brokers. Put simply, maintain a $100,000 balance or spend at least $30 in commissions each month, and you will be in the clear; otherwise, charges for inactivity can reach up to $20 per month. For everyday investors, we recommend IBKR Lite or exploring our list of the best brokers for free trading.

IBKR Lite: With IBKR Lite, there are no inactivity fees or data fees. All US stock and ETF trades are $0, while options trades follow the same IBKR Pro pricing. The main caveat to IBKR Lite is the lower quality order executions. Like other $0 brokers, under IBKR Lite, Interactive Brokers makes money off its order flow. Overall, IBKR Pro is designed for professionals, while IBKR Lite is designed for casual investors.

Platforms & Tools

Rank: 3rd (of 16)

The flagship platform Interactive Brokers offers is desktop-based Trader Workstation (TWS), which supports trading everything under the sun, including global assets. While TWS is not designed for new investors, it easily ranks among the best trading platforms in the industry.

Professional tools galore: Trading tools within TWS designed for seasoned traders are widespread: Algo trading, Options Strategy Lab, Volatility Lab, Risk Navigator, Market Scanner, Strategy Builder, and Portfolio Builder, to name a few. Watch lists can include anything from equities to individual options contracts, futures, forex, warrants – you name it. A staggering 494 data points are available for column customization.

IBot: IBot, also available in TWS mobile, uses a foundation of artificial intelligence to quickly service customer requests via chat (or voice in the iPhone app). Portfolio information, orders, quotes, and more are all supported. Think, "What's the last price of GOOG?" or, "Chart AAPL vs. MSFT" or, "Buy 100 shares of FB." Only TD Ameritrade can go toe-to-toe with IBot.

TWS drawbacks: Tasks such as pulling up a stock to trade are tricky due to the vast array of securities available to trade. For example, typing in "AAPL" for Apple yields a slew of possible matches, which can be overwhelming for non-professionals. Also, automated technical analysis tools (e.g., Recognia) are available only as a paid subscription add-on.

Client Portal: For less experienced traders, Interactive Brokers offers the Portal platform through its website. In summary, Portal includes all the core features necessary to trade and manage a basic portfolio. Portal is the primary trading experience for IBKR Lite customers, which means it is far less robust, but also far easier to use. In my testing, I found it to be good, but not great. It's new as of late 2019, so it is safe to assume that improvements will be observed over time.



Rank: 6th (of 16)

Conducting research using the Trader Workstation (TWS) platform is no easy task. That said, for traders that commit and learn the platform, TWS includes advanced research tools seasoned traders desire, such as scanning and back-testing.

Good stuff: Research highlights include numerous screeners, extensive back-testing functionality, and portfolio analysis tools, which are all excellent. For traders looking to conduct specific research, Interactive Brokers offers dozens of third-party provider feeds a la carte, including Morningstar, which are available for a monthly fee. Any provider package purchased integrates straight into TWS.

Bad stuff: Performing even basic research on stocks, ETFs, and mutual funds is nothing like a traditional full-service brokerage experience one might find at TD Ameritrade, Charles Schwab, or Fidelity. You have to learn how to navigate TWS to find the information you want; there are no streamlined views. Bottom line, while TWS checks off quite a few boxes for research, the user experience is poor.

Fundamentals Explorer: In late 2019, Interactive Brokers rolled out Fundamentals Explorer as a new tool within Client Portal, built for everyday investors to perform traditional fundamental research on stocks. It's light years ahead of anything Interactive Brokers had prior (the data is also incorporated into the mobile app under quotes). Fundamentals Explorer will eventually make its way into TWS, and the foundation has been laid for adding ETFs alongside Mutual Funds research. Overall, customers should expect to see improvements throughout 2020.

PortfolioAnalyst: Stepping away from traditional research, PortfolioAnalyst provides traders hedge fund-level reporting on their portfolio's performance and makeup. Interactive Brokers also offers a free version for non-clients where you can link all your individual accounts and run reporting. It isn't as insightful and easy to use as, say, Personal Capital. Still, it's a compelling tool for traders with assets spread across numerous institutions.

Mobile Trading

Mobile trading with Interactive Brokers is well supported across all devices. From lightning-quick streaming data to full-featured order entry and portfolio management, Interactive Brokers includes everything professionals require to go trade on the go.

Charting: Charting is robust, including 70 optional indicators and easy customizations; however, panning isn't as smooth as newer HTML5 charting applications. Additionally, some features one would expect are not included, such as stock and/or index comparisons.

Considerations: One notable drawback to the app is that stock alerts cannot be delivered via push notification. Instead, alerts are delivered via email, which is baffling considering how sophisticated Interactive Brokers technology is otherwise.


Offering of Investments

Rank: 1st (of 16)

Interactive Brokers provides the most diverse offering in the industry and leads by a wide margin in multiple areas, including international trading. Globally, customers can trade across more than 135 international markets in 33 countries.

Cash management: Any portfolio cash sitting idle beyond $10,000 will earn interest. The rate varies depending on the account balance; the higher your account balance, the more interest it accrues. For clients with high cash balances, cash management with Interactive Brokers is a great perk.

Forex: Retail forex trading is not offered in the United States unless you are designated as an "Eligible Contract Participant" by Interactive Brokers. More specifically, this means being an individual or organization with assets of over $10 million.

Final Thoughts

With industry-leading commission rates for professional traders, more than 60 optional order types, trading in more than 135 international markets, and a robust trade platform suitable for any professional, Interactive Brokers is an excellent choice for investors who fit into its target mold.
