TD Ameritrade vs Interactive Brokers. Both are top-tier US-regulated brokers, but with different strengths. TD Ameritrade (thinkorswim, now Schwab) is loved for its visual, beginner-friendly-yet-powerful platform and options tools. Interactive Brokers offers lower costs, genuine global market access and real forex trading, favoured by professionals and international traders. For US stocks/options on a great platform, thinkorswim wins; for forex or worldwide markets, Interactive Brokers is the stronger choice.
