What Happened to TD Ameritrade? The Schwab Migration Explained

By Sam Davila on 2026-07-10 - 2 min read

TD Ameritrade no longer exists as a standalone broker. Charles Schwab acquired it in 2020, and by 2024 essentially all TD Ameritrade accounts had been migrated onto Schwab's platform. If you are searching for TD Ameritrade logins, APIs, or app connections in 2026, everything now points to Schwab. Here is what changed and what it means for your accounts and connected apps.

The timeline in brief

  • 2020: Schwab completes its purchase of TD Ameritrade, creating the largest retail brokerage in the US.
  • 2023: account migrations begin in waves; login credentials, positions, and history move to Schwab.
  • 2024: migration completes; TD Ameritrade's platforms are retired, with one big exception below.

thinkorswim survived

The best-known piece of TD Ameritrade, the thinkorswim trading platform, was kept and is now Schwab's flagship active-trader platform on desktop, web, and mobile. If thinkorswim was why you used TDA, you did not lose it; you access it through a Schwab account now.

What happened to connected apps and the API

TD Ameritrade also had one of the most widely used retail broker APIs, powering a generation of portfolio trackers and trading tools. That API was retired with the migration, replaced by Schwab's own API program with OAuth authorization. Practical consequences:

  • Old TDA app connections stopped working at migration; apps had to rebuild against Schwab's API.
  • Any tool still advertising TD Ameritrade support without mentioning Schwab has not been updated, which is itself a signal about that tool's maintenance.
  • Reconnecting is done the modern way: OAuth approval on Schwab's site, revocable from Schwab's security settings.

What to do if you had a TDA account

Your account is a Schwab account now; log in through Schwab, confirm your positions and cost basis carried over, re-establish any app connections you relied on, and check that your two-factor settings survived the move. Multi-account traders reconnecting their stack can link the migrated Schwab account to Sentient Logic to bring it back into a combined, AI-analyzed portfolio view alongside their other brokers.
