Best for

  • Ideal for long-term systematic investors and active traders with existing Schwab or legacy TD Ameritrade accounts.
  • Supports equity momentum and factor-based rotation strategies, covered call programs, and ETF rebalancing automation.
  • Access to Schwab's broad fixed-income inventory enables bond ladder automation and yield-curve strategies.
  • The scale and regulatory standing of Schwab makes this connector suitable for larger automated portfolios that require institutional-grade reliability.

Important

Schwab uses OAuth 2.0 with a 30-minute access token and a 7-day refresh token — the connector must handle automatic token refresh to maintain uninterrupted automated trading.
TD Ameritrade credentials do NOT work with the Schwab API; legacy thinkorswim API users must re-register on the Schwab Developer Portal.
Paper trading is available via the Schwab Developer sandbox (separate app registration required).
US equities and options: NYSE/NASDAQ session 09:30–16:00 ET.
Streaming quotes use Server-Sent Events (SSE); REST polling is heavily rate-limited on Schwab's production API.
