Brokerage Firm Backdrop

thinkorswim is a powerful desktop program owned and maintained by Charles Schwab. Although thinkorswim isn’t the only trading resource Charles Schwab offers, it is the one platform active traders use most frequently.

Similarly, Interactive Brokers offers multiple trading resources, one of the most salient being its desktop software Trader Workstation. TWS and thinkorswim have a lot of tools in common; but there are important differences between them.

What Can Be Traded on the Two Platforms

On thinkorswim, traders can buy and sell stocks, ETFs, closed-end funds, futures, and forex. Although Charles Schwab offers bonds and mutual funds, they can’t be traded on the desktop system.

On Trader Workstation, the same investment vehicles that thinkorswim can handle can be traded. Moreover, Interactive Brokers has enabled its desktop software to trade warrants, contracts for difference, structured products, bonds, and global securities.

Software Overview

Both platforms are launched from the desktop. At the login screen, each program offers a demo mode in case you want to practice the software without risking real money. Because both are very complex, we definitely recommend choosing this option (frequently).

Once inside, neither platform is user-friendly. This isn’t all that surprising given the professional nature of these programs. TWS offers two layouts by default: Mosaic and Classic. We recommend trying each one.

thinkorswim has only one layout, although it can be adjusted by going to the Setup menu in the upper-right screen (noted with a gear icon), and then selecting Look and feel inside the menu. There are light and dark layout choices, and font sizes can be changed. Modifications can be saved to a template as well.


Other Software

Charles Schwab has a thinkorswim mobile app. As you might expect, this mobile platform has very advanced charting, a sophisticated order ticket, and other professional-level trading tools. The broker’s website itself provides a very good trading experience and includes a trade bar.

Interactive Brokers also has a very advanced mobile app. It incorporates two trading tickets, advanced graphs, and more. Like the thinkorswim app, it too has a simulated trading mode.

IB customers can use a client portal, whose trade ticket is enabled for whole-dollar investing. WebTrader is an HTML-based system that has low-level charting but an excellent trade ticket.

Security Research

Both TWS and thinkorswim deliver live streaming of financial news. In TWS’s case, it’s Bloomberg (oddly limited to just 15 minutes per day). On thinkorswim, Charles Schwab offers CNBC and its own video network, aptly titled Charles Schwab Network.

IBKR vs thinkorswim

For additional news, both platforms have widgets for news articles and upcoming economic events. thinkorswim’s economic calendar is color-coded, which makes it easier to use when sorting through splits, conference calls, earnings announcements, dividends, and other events.

Security screeners are available on the two desktop platforms and on the brokers’ websites. During our inquiry, we found Charles Schwab’s web-based stock screener the easiest to use. However, it is only able to search the U.S. marketplace. For foreign securities, you’ll need to use Trader Workstation’s stock screener. TWS also has a bond screener, something that thinkorswim lacks.


For stock research, Interactive Brokers offers free reports from Zacks Investment Research. They are available on Trader Workstation and include trade recommendations and price targets. On the client portal, we found trade recommendations from TipRanks and many analysts, such as:

  • Goldman Sachs
  • Morgan Stanley
  • Argus
  • Raymond James
  • Mizuho Securities

Although stock reports can’t be accessed on thinkorswim, Charles Schwab’s website does have them. We found pdf briefs from:

  • CFRA
  • New Constructs
  • Research Team
  • Ford Equity Research
  • Market Edge
  • Vickers
  • Credit Suisse

Pre-Market and After-Hours Trading

If you can’t trade during the regular session because you have a day job, no problem. You can trade early in the morning and late into the evening with either Interactive Brokers or Charles Schwab.

IB’s early-bird session starts at 4:00 am, EST. Its late-night period ends at 8:00 pm. Charles Schwab has the same after-hours session, but its morning session begins at 7:00 am. While this is a weakness, Charles Schwab does offer overnight trading in several ETFs, a fantastic service that Interactive Brokers doesn’t have.

Level II Quotes

Level II data is available both on Trader Workstation and on thinkorswim. The one difference is that Interactive Brokers charges for the data. At Charles Schwab, even professionals get Level II quotes for free.

Direct-Access Routing

Because Trader Workstation and thinkorswim are professional-level platforms, it should come as no surprise that direct-access routing is enabled by default. Charles Schwab, however, provides just two routes for equity orders (besides the auto default); they are Nasdaq and Arca.

On Trader Workstation, we found no less than twenty destinations, including an algorithmic trading option.

Maker-Taker Fees

With so many destinations, it shouldn’t be surprising that IB provides maker-taker fees (available only to IBKR Pro customers). Charles Schwab does not offer this commission service.

Trading on Margin

Another big difference between Interactive Brokers and its rival here is in the margin arena. On Trader Workstation, margin details for each entered ticker symbol are shown. That is not the case on thinkorswim.

Margin rates are also very different. Lite customers at IB pay 7,83%. Charles Schwab, on the other hand, is currently at 11,825% to 13,575%.

Other Services

Dividend Reinvestment Program: Charles Schwab and Interactive Brokers convert dividends into additional shares free of charge. However, at Interactive Brokers, it’s only possible to enroll an entire account.

IRAs: Charles Schwab has more retirement accounts than Interactive Brokers.
