TD Ameritrade

TD Ameritrade was one of the largest and most respected online brokerages in the United States before its acquisition by Charles Schwab, completed in 2024. Known for its industry-leading thinkorswim platform, TD Ameritrade offered commission-free stock and ETF trades, robust options trading capabilities, extensive research and education, and a wide range of investment products. Existing TD Ameritrade accounts have been migrated to Schwab, but the legacy of TD Ameritrade lives on through the thinkorswim platform, which Schwab has adopted as its advanced trading interface. TD Ameritrade was particularly beloved by active traders and options traders for its powerful charting, real-time streaming data, and paper trading capabilities. While new accounts are now opened through Schwab, the TD Ameritrade brand remains relevant for traders researching the platform's heritage and understanding what capabilities transferred to Schwab.
