TD Ameritrade vs Interactive Brokers: Ease of Use and Trading Offerings

Both TD Ameritrade and Interactive Brokers provide you with a wide range of investment products to choose from via their online platforms. The IB trading platform is known as Trader Workstation, whereas TD Ameritrade’s is called thinkorswim.

At TD Ameritrade, you can invest in the following:

And on the Interactive Brokers app, you can choose from the following trading options:

  • Mutual Funds
  • CFDs
  • Fixed Income
  • Indices
  • Metals
  • Currencies
  • SSFs
  • Structured Products
  • Warrants
  • ETFs
  • FOPs
  • Futures
  • Options
  • Stocks

Now let’s take a look at some of the most popular trading types in further detail:

Day trading

Both firms give you the option of taking shorter positions. However, Interactive Brokers offers several key features that TD Ameritrade doesn’t, such as a check margin tool that displays the margin requirements for shorting certain security.

On the flip side, the TD Ameritrade day trading fees are non-existent for Level II quotes. So whether you’re a pro or beginner, you will get this for free.

IB’s Trader Workstation platform seems to offer a much more comprehensive day trading platform, though. For instance, while both TD Ameritrade and Interactive Brokers provide direct-access routing, the latter has many more venues available.

Forex trading

While Interactive Brokers edges it in the thinkorswim vs Interactive Brokers battle regarding day trading, TD Ameritrade levels the field on the Forex trading front. Of course, it is quite rare to have two top brokerages that provide Forex trading, so this alone should be applauded.

However, TD Ameritrade is the clear winner. While Interactive Brokers provides 23 currency pairs, you will have access to more than 70 on the thinkorswim platform.

Furthermore, TD Ameritrade does not charge commission on Forex trading, whereas IB does. IB takes a percentage on every trade value, with a $1-$2 minimum commission in place.

Not only is the lack of any TD Ameritrade Forex commission attractive, but the platform is easier to use too. The interface is intuitive, and there are greater display possibilities for each dealing box.

Margin trading

Margin accounts are available at both brokerages. However, the fees differ considerably. While IB will charge a maximum of 1.59% on any balance, the TD Ameritrade margin rates are a lot higher. The maximum is 9.5%.

There is also a great feature on Interactive Brokers that enables you to view margin details, such as maintenance and initial requirements, for every entered ticker symbol. This is a nice touch, and it’s not something you will find on thinkorswim.

Ease of use

Now, let’s compare TD Ameritrade vs Interactive Brokers in terms of usability. TD Ameritrade has long been championed for its user-friendly platform, making it easy for beginners to get started. You can check out our TD Ameritrade review for more information.

Opening an account with TD Ameritrade is certainly easy, and you can do so via their desktop site or mobile application. There are a lot of different account types for you to choose from. However, to make it even easier, TD Ameritrade provides a “common types” section, which can help you narrow down your search.

Notably, IBKR has made a special effort to improve its onboarding journey over the years, and now it’s a lot more straightforward than it used to be. You can open an account without funding it immediately. Choosing from the various account types can be a bit more complex, though.

In terms of the trading platforms themselves, you will find a steeper learning curve with the Trader Workstation than you will with thinkorswim. Also, customizing your trading experience may take you a little bit longer at IBKR.

  • Tiered Pricing – The brokerage commission is dependent upon volume, as well as clearing, regulatory, and exchange fees.

There is also a free account option, but this is not available for all Interactive Brokers account types. In addition, it’s only for stock traders based in the US. When this is coupled with the $0 minimum deposit, finding the best-performing stocks becomes a much cheaper venture.
