Broker Commission Rate

 Interactive BrokersMerrill EdgeTD AmeritradeE*TRADE
Standard Stock Flat$4.95$6.95$6.95$6.95
Options Per Contract$0.70$0.75$0.75$0.75
Options Base Level$0.00$6.95$6.95$6.95

Interactive Brokers offer low commissions through its structure for stock and ETFs. The brokerage commission structure favors high-volume traders who frequently trade, offering 0.5 cents per share. There is a minimum trade commission of $1 with the maximum being 1% of the total trade value. Exchange and regulatory fees are included, and there is also the offer of tiered pricing, so rates can be even lower.

The tiered pricing is for investors who trade over 300,000 shares a month, and they can pay 0.2 cents or even less per share, although that depends on trade volume. Traders on this plan will find that regulatory and exchange fees are extra, but very high-volume traders may find rates go even lower.

Trading options are also offered at a low price. Each contract has a 70-cent charge, and there is no base, with a minimum of $1 per order. Larger volumes will also attract discounts.

Margin rates are also low at Interactive Brokers. The maximum rate is 1.5% on top of the benchmark rate and investors will be charged a blended rate by the broker based on how large the margin loan happens to be. On its website the broker has a calculator, so traders can quickly work out the math based on their balance.

Interactive Brokers charges inactivity fees, so traders who have accounts that have balances under $100,000 have to meet a minimum in trade commissions of $10 a month. Failing to meet that minimum will incur a monthly fee for the difference. For accounts that have $2,000 or less as their equity balance, there are minimum trade commissions of $20. However, for clients who are 25 or under, there is a minimum monthly trade commission of $3.

Customer service

As mentioned previously, customer service can be weak, and although it is available by phone, chat and email, and customer care is accessible in several languages, response times can be slow.

Anything to do with security issues, such as security tokens or resets, has to be dealt with by phone. Phone access is available 24 hours a day during market days, though that moves to foreign venues overnight and that can make contact more difficult. Using the chat function can lead to long waiting times, especially during outages, though they are infrequent. Trades that are placed by phone during an outage will generally have fees waived. The chat room operators are very knowledgeable about the platform software and will help new and inexperienced users through any difficulties they have in using them effectively.

Interactive Brokers provides a comprehensive knowledge base for customers and its web-based account management interface can handle common tasks such as fund transfers, tax reporting, and account changes.



Platform features and tools

Trader Workstation (TWS) is the main platform offered by Interactive Brokers and has been developed so that anything can be traded through the markets, and that includes global assets. Unsurprisingly it has been designed for use by traders who have considerable market experience as – compared to other platforms that are easier to use – it takes some time and effort to master. TWS is probably not ideal for investors who are new to trading, but once they have found their feet in the trading world, they might want to consider it for future work.  One interesting feature of the TWS offering is that users can consider their appetite for operational risk and select which version of TWS they use. ‘TWS Latest’ is the version that is updated most frequently and includes all the latest features.  ‘TWS’ is updated less frequently, so whilst not featuring all the latest tools will be more stable.

The default dashboard within TWS is called Mosaic which is a grouping of windows and monitors that provide your: analytics, trades, quotes, research, news, AI support and trade portfolio information in one place. It supports an enormous range of asset classes and has geared it so that when any stock symbol is typed in a summary of available securities is displayed. Watch lists range through individual options contracts, forex, futures, warrants, and equities so a close eye can be kept on all the markets. There are a vast number of different watch list columns and monitors that can be fully customized, though sometimes there can be a lot of matches when trying to find certain companies and these could become confusing, especially for inexperienced users.

With 121 optional charting indicators and studies available to be added to any chart, there is plenty of scope for traders to customize them to cover all possible options, and though the number of studies is lower than those for some other brokers it should be sufficient for most traders. Nine tools for markups can be accessed and though these include notes, zooming and trendlines it does not have tools such as channels, resistance lines, and support.

However, TWS does have functions that include viewing historical trades, trading off charts, alerts, index overlays, and comparisons. There are many other tools and features available, such as Layouts Library, FYI, Trader Journal, and IBot, the latter using a basis of artificial intelligence (AI) to service customer requests quickly.

Mobile trading

In general, the mobile trading app from Interactive Brokers is easy and fast to use, and mobile devices are supported. That includes Android smartphones and tablets and iOS with iPads and iPhones as well as Apple Watch. Data streams very quickly and there are full-featured portfolio management and order entry.

Usability can be problematic because although there are charts with 68 optional studies, they are not flexible. Charting is also affected by not having many stock comparisons for those to index, and a customizable home screen is not available through the app. There are some other features lacking, including the absence of videos on demand and the ability to stream live TV.

Traders will find watch list syncing and stock alerts with basic fields as well as a touch ID, and the broker’s mobile app also has after-hours charting and custom screening and scanning, making it overall a tool that has a core functionality that traders need to be able to trade effectively.


Robo trading

The Application Programming Interface (API) that Interactive Brokers provides allows investors to trade all the products that are supported by the broker’s TWS platform. These include stocks, futures, options, bonds, and forex.

API has been specifically designed for professional traders who want an algorithmic trading solution that is extremely effective. There are many advantages to using API for traders who wish to design and implement a programmed trading strategy. They include:

  • Multiple programming languages support that include Java, C++, Visual Basic for ActiveX and DDE for Excel. The broker considers this to be more reliable and robust in comparison to languages written in a simplistic, non-standard environment.
  • No dedicated server is needed so there is no FIX system with a high overhead required. There is access to the order entry and order management features of TWS using API.
  • For traders with less experience, there are sample applications to help them start the process, so they can develop their own applications and hone them to as near perfection as possible by initially using Excel before migrating to a different language.

Traders who have experience of programming with Java, for example, will find a steep learning curve and a longer time to production; however, it can be used it on all platforms, including Mac, Windows and UNIX/LINUX. Most users experience a very robust, reliable and high-performance system.



Research and learning

Interactive Brokers provides a range of research and education options through various third-party providers, the broker not having its own in-house research team. Investors can access the research functions via the Information System menu point (IBIS), and free research that includes the top newspapers and stock reports from the likes of Thomson Reuters. Research and analysis are continuously supported by time-saving tools (such as the Merger Arbitrage modeller) that lead the user towards being able to execute a trade based off their hopefully improved understanding.

Daily video commentaries made by the broker and third parties, can be accessed free of charge, as can technical analysis tools and fundamental data. The Daily Lineup function gives a summary of the latest important market news as well as the latest recommendations from analysts. Also included are earnings and an economic calendar that help prepare traders for a fast start to their working day.



There are numerous opportunities to delve into the educational information provided by Interactive Brokers to dig deeper into all aspects of market trading. Online courses, webinars, and educational videos are available through the Traders University, and there is a useful glossary that can be used to look up unfamiliar expressions, words and acronyms. Courses can be chosen depending on the level of professionalism a trader has reached, and there is a very useful course that shows how to use the broker’s trader application.

Interactive Brokers ProsInteractive Brokers Cons
Well regulatedAccount opening slow
Competitive fee structureLimited funding and withdrawal options
Very Good platform
Weak customer service
Wide range of charting optionsFixed Fees
Extensive market range
Effective mobile trading


There is little doubt that Interactive Brokers is aimed at experienced, professional traders. The platform is in fact often used by institutional grade portfolio managers and start-up hedge fund managers who are incubating new funds.  Whilst those just getting started will find it a steep learning curve they might want to persevere if they are serious about their trading future.

One aspect that stands out is the low cost of trading and depending on the volume of trades the costs can be further reduced.  Advanced level traders, with a more considered approach to risk-return benefit from the lower trading costs not creating as much of a drag on performance as with other brokers. The product portfolio is extensive, and this gives traders opportunities to make money on practically every type of market available.

Another positive aspect is the TWS trading platform that is highly sophisticated, quite complex to learn initially but provides almost unlimited functionalities. Unfortunately, the web-trading platform is limited in its functions and is not very convenient to use.

There are plenty of research and education tools to access, and the mobile trading platform is generally okay to use. Though customer care is weaker than it should be, and account opening can be slow, the broker has decades of experience, is well regulated and is certainly worth considering as an appropriate and effective trading platform.
