Our Analysis

Fidelity (4.7/5) and TD Ameritrade (4.4/5, now merged into Schwab) are both top-tier US brokers, though TD Ameritrade no longer accepts new accounts. Fidelity leads in research, customer service, and zero-fee index funds. TD Ameritrade's legacy is ThinkorSwim — the most powerful free trading platform in the industry — which now lives under Schwab.

Fidelity's differentiator remains its research quality and zero-expense-ratio funds like FZROX and FZILX that no other broker matches. TD Ameritrade's ThinkorSwim, with custom scripting, advanced options analysis, and extensive paper trading, remains accessible through Charles Schwab.

If you're choosing a new broker today, the comparison is effectively Fidelity vs Schwab (which now owns ThinkorSwim). Choose Fidelity for research, customer service, and low-cost investing. Go to Schwab for ThinkorSwim's advanced trading tools and banking integration. Existing TD Ameritrade users are being migrated to Schwab automatically.
