Founded nearly 40 years ago, Interactive Brokers (IBKR) is known for its industry-leading commissions schedule, margin rates, and support for international trading.

By presenting one universal portal through which clients can trade on more than 100 market centers in 24 different countries, and deal in stocks, options, ETFs, futures, forex, bonds, and CFDs, Interactive Brokers has something to offer any seasoned trader who has at least $10,000 ($100,000 for margin accounts).

Commissions & Fees

With its core clientele being professional traders and institutions, providing the lowest commissions schedule available is critical for Interactive Brokers. In our rigorous assessment, they deliver without question.

First, it is important to note that Interactive Brokers does not accept payment for order flow, a key element in providing quality order execution. In our assessment of order execution for the 2017 Review, the broker came second behind Fidelity. For more, see our guide to order execution.

Overall, Interactive Brokers unquestionably reigns supreme in the category of commissions and fees.

Interactive Brokers also leads the industry with the lowest margin rates, which vary from 1.91% down to a staggering 1.41% for clients who hold more than $1 million with the brokerage.

Speaking of equity trades, rates start at $.005 per share with the fixed-rate structure ($1 minimum). Alternatively, the tiered-rate structure, which starts at $.0035 per share, can be used, but routing is factored in, which can add or reduce the cost, depending on whether the client is removing or adding liquidity. Some math will reveal that for small order sizes, i.e., several hundred shares, Interactive Brokers is a fantastic deal. Trade several thousand shares or more though, and Interactive Brokers quickly becomes pricey.

Options Per Contract Fee$0.70$0.60$0.50$0.50$0.50
Commissions & Fees 4.5 Stars 4 Stars 3.5 Stars 4.5 Stars 4.5 Stars

Options are $.70 per contract with no minimums, and active options traders will enjoy the fact that exercise and assignments are practically free. Like tiered equity trades, per contract fees tier down as total shares traded increases.

New and casual investors should be aware of the miscellaneous fees and minimums charged by Interactive Brokers. Put simply, spend at least $30 in commissions each month and you are in the clear; otherwise, charges for inactivity can reach up to $20 per month. While far lower than the minimum spend required at say Lightspeed, it is still something to keep in mind. A full breakdown can be found on the Commissions & Fees notes further down the page.

Overall, Interactive Brokers unquestionably reigns supreme in the category of commissions and fees.

Platforms & Tools

The flagship platform Interactive Brokers offers is its Trader Workstation (TWS). The platform is set up to trade everything under the sun, including global assets, and is designed to be used by traders with ample market experience. The default experience is called Mosaic, while clients also have access to view what is called Classic TWS (the original version of the platform).

Interactive Brokers Mosaic

Because Interactive Brokers supports so many asset classes, it had to rethink its position and watch list management. What they came up with, which takes some getting used to, is extremely efficient. Type in any stock symbol and you will see a summary of available securities. Watch lists can include anything from equities to individual options contracts, futures, forex, warrants, you name it. I preferred the Mosaic view, although I know many long-term clients prefer the Classic view.

Interactive Brokers Mosaic watch list

Watch lists can have up to 338 different columns, and to say they are fully customizable is truly an understatement. No broker offers an experience like TWS. Beyond learning how to effectively build watch lists, I found only one usability disadvantage that comes from supporting so many investment types, and that is pulling up quotes or trading securities. Even typing in AAPL for Apple yields a slew of possible matches, which can be overwhelming for non-professionals.

Turning to charting, technical traders will find nearly everything they need. One hundred and twenty four different studies are available to be added to any chart, and customizations cover every possible option. Note though, while 124 option indicators are impressive, TWS still trails the 270 and 370 offered by TradeStation and TD Ameritrade thinkorswim, respectively. Out of all the tools on TWS, I found the charts to have the most user-friendly interface.

Interactive Brokers TWS Mosaic charts

Considering the depth of functionality, I was surprised to find only eight tools for mark ups. While the basics are present – trendlines, notes, zooming, Fibonacci, etc. – important tools such as support and resistance lines, channels, and the like are missing. Pickiness aside, the charts on TWS have all the core functionality required to succeed: viewing historical trades, alerts, trading off charts, comparisons, and index overlays, to name several.

There is no question TWS is built for professional trading as there are, for example, a staggering 63 different order types available for clients to use, by far the most in the industry.

Alongside charts, TWS is also home to a variety of other tools not covered in this review. Algo trading, Options Strategy Lab, Volatility Lab, Risk Navigator, Market Scanner, Strategy Builder, and Portfolio Builder, to name a few, are all available within TWS. There is no question TWS is built for professional trading as there are, for example, a staggering 63 different order types available for clients to use, by far the most in the industry.

Interactive Brokers TWS Volatility Lab

After assessing TWS across 58 individual variables, the platform easily ranked among the best in the industry. Certain tools, such as charting, lack depth compared to those the top-ranked platforms use; however, overall, TWS delivers.

Lastly, for clients traveling without access to their desktops, or for clients looking to simply monitor their portfolio, place trades, and view watch lists, IB WebTrader is a good solution. After loading WebTrader, I found a detailed summary of my portfolio balances and margin requirements alongside a full spectrum order ticket.  When I say full spectrum, I mean trading for all asset classes is supported. The only limitations are algo orders and other advanced order types.

Interactive Brokers Web Trader

Pulling quotes will provide only a basic high-level summary, an extremely rudimentary chart I recommend be avoided altogether, and an option chain. Basic stock screening is also present alongside a high-level international market summary tab, Market Pulse. Customizations are essentially non-existent throughout, although streaming real-time quotes are found throughout, which is essential.

Interactive Brokers Market Pulse

Bottom line, the focus of WebTrader is to monitor portfolios and manage orders; it is not designed to be used as a standalone. It accomplishes these functions well.


Being a professional trader-focused brokerage, Interactive Brokers is not known for its research offering. Bundled with the platform clients will find what they need to conduct mostly thorough research for stocks, decent research for ETFs, and little to no research for Mutual Funds.

That said, Interactive Brokers does offer a variety of third-party provider feeds a la carte, including Morningstar, which are available for a monthly fee.

Mobile Trading

Mobile trading with Interactive Brokers is mostly an enjoyable experience. All devices are supported including iPhone, iPad, Apple Watch, Android smartphone, and Android tablets.

When testing the iPhone app, I found the app had everything I needed to trade effectively.

The drawbacks with the experience center around usability. For example, the charts have 68 different optional studies, which is great, but the charts are not flexible. If you set the settings to view a daily chart of the past six months, that’s the only view you will get until you adjust the settings; there is no panning. Also, two-factor login with Touch ID is supported, but you have-to use a secondary IB Key app instead of simply Touch ID logging into the actual app as you load it.

Other drawbacks include a lack of stock and/or index comparisons in charting, no customizable home screen, no streaming live TV or videos on demand, no Level II quotes, and only being able to set basic stock alerts without push notifications support. You also cannot perform ACH account transfers within the app.

Cons aside, I found the app had a handful of nice features not often found across the industry, including custom screening /scanning and after-hours charting.

As stated previously, mobile trading with Interactive Brokers is well supported across all devices and has the core functionality required by traders to go about their business and trade effectively.

Other Notes

One notable weak spot in Interactive Brokers’ offering is its customer service. During testing for our 2017 Review, we found support to be consistently poor regardless of the channel being used: phone, email, live chat. The broker placed 15th out of 16 brokers we tested.

While Interactive Brokers does not cover advisor services and institutional asset management, the company is unique in that it offers what it calls the Investor’s Marketplace. The tagline of the service is to “Find the right service provider for your trading needs.” For example, I presented myself as “an individual investor seeking an advisor” and a list of several hundred advisors popped up. Hedge funds, research and technology providers, administrative service providers, and the like are all included.

Final Thoughts

With industry-leading commission rates, more than 50 different order types, staggering low margin rates, support for every investment imaginable, trading in more than 100 international markets, and a robust trade platform suitable for any professional, Interactive Brokers is a great choice for investors who fit into its target mold.


For our 2017 Stock Broker Review we assessed, rated, and ranked sixteen different online brokers over a period of six months. In total, we conducted 349 customer service tests, collected 5,277 data points, and produced over 40,000 words of research. How we test.
