thinkorswim is Charles Schwab's advanced trading platform, offering professional-grade charting, options analysis, backtesting, and paper trading. Originally built by TD Ameritrade, it has become the go-to platform for active traders and options specialists who need institutional-quality tools at retail pricing.
thinkorswim is widely regarded as the best options trading platform for retail investors. Schwab's acquisition of TD Ameritrade strengthened its position with banking integration, but created transition uncertainty. It competes with IBKR on professional tools and with Robinhood and Webull on attracting new traders.
