Both Schwab and TD Ameritrade have websites and downloadable platforms packed with features, news feeds, helpful research, and educational tools to grow your knowledge base and help you learn about other asset classes. Both were ranked in our top 5; TD Ameritrade's slightly higher costs structure generated fewer points than Schwab's.


On November 25, 2019, Charles Schwab announced a buyout of TD Ameritrade’s online brokerage. The transaction itself is expected to close in the second half of 2020, and in the meantime, the two firms will operate autonomously. Schwab expects the merger of its platforms and services to take place within three years of the close of the deal.

Choosing between these two comes down to personal preference, and perhaps the geographic availability of one of their offices. Very active derivatives traders may prefer TD Ameritrade's thinkorswim platform, while fundamental-minded stock and ETF traders will appreciate Charles Schwab's proprietary equity ratings and research.

TD Ameritrade lets you open an account for free. Schwab lets you open an account without funding it also, but there's a catch: clients must also open a free, no minimum High Yield Investor Checking account linked to the Schwab One brokerage account. Without the link, there is a $100 minimum with a $100/month direct deposit or $1,000 minimum for the Schwab One brokerage account.

Trade Experience

Schwab has several platforms that you can launch after logging on to their flagship website, or you can download the StreetSmart Edge platform to your desktop, or run it from the cloud. StreetSmart Edge is Schwab’s advanced platform which features streaming real-time data and news along with a customizable charting toolkit. All of the platforms have the All In One Trade Ticket available, which lets you build an order using the asset class you choose in a flexible and intuitive way. Quotes update in real time. Schwab monitors its execution quality statistics, and the reports provided to clients after every trade include how much price improvement was achieved.

TD Ameritrade customers can choose from several platforms, from their standard "green site" on the web to their platform for frequent options traders, called thinkorswim. The downloadable thinkorswim platform is extremely customizable, allowing the client to define color schemes, layouts, and trading defaults. Over the last year or so, the standard website has added numerous customization options, including the Dock tool, which is a customizable dashboard. Trade tickets are ubiquitous on all platforms, so you can enter an order no matter where you are. TD Ameritrade’s order routing algorithms seek out price improvement, which can offset the cost of placing a trade. You’ll find streaming real-time data on all platforms.

Schwab eliminated its base commissions for stock and ETF transactions as well as its per-leg fee for options trades. Commissions are also eliminated for OTCBB (penny stock) transactions, which is a differentiator. Options trades are now $0.65 per contract, which is a large price cut for smaller multi-leg trades. Their margin rates are average, though lower than TD Ameritrade and E*TRADE. 

Previously the most expensive of the major online brokers, TD Ameritrade eliminated base trading commissions on equities, ETFs, and options for U.S.-based customers. Though they have cut trading commissions, their margin interest rates remain on the high end of the scale.
