The TD Ameritrade API died in May 2024.
Schwab never gave it back. We start you with one.
If you built bots, alerts, or studies on thinkorswim, you know the story: the TDA API was sunset on 10 May 2024, the Schwab Trader API that replaced it is gated to fintech partners, and thinkScript still has no programmatic surface at all. EventTrader gives you what retail automation actually needs — API keys on signup, real documentation, an SDK, and webhook execution — free with an account.
A real retail API, day one
Documented REST API with key auth (X-API-Key) or JWT — no partner agreement, no application queue. Full docs at /api-docs, SDK at /sdk, and an MCP server (pip install cymetica-eventtrader-mcp) so your AI tooling can trade and query markets directly.
Alerts that survive platform updates
Server-side alerts evaluated on our infrastructure — price moves, indicator conditions, association heat, multi-condition AND/OR logic. They don't expire, they don't get wiped by a desktop release, and there's no "TooComplexException" ceiling.
Auto-execution via webhooks
Point any alert — ours or an external system's — at your personal webhook endpoint and it executes here with server-side SL/TP. Delivery is retried and confirmed, not fire-and-forget. The job that now requires a third-party bridge and a monthly fee elsewhere is included free.
What happened to your automation — and what's on the other side
| Capability | thinkorswim / Schwab today | EventTrader |
|---|---|---|
| Retail API access | TDA API sunset 10 May 2024; Schwab Trader API gated to fintech partners, no retail timeline | API key issued on free signup |
| Scripting surface | thinkScript: no programmatic API, recursion limits, studies break on platform updates | REST + SDK + MCP server; strategy bots you can clone without writing code |
| Paper-testing your bot | Schwab API sandbox is synthetic-data-only | Live public market data, free read access |
| Alert persistence | Studies and workflows lost or broken in the Schwab migration | Server-side, non-expiring, survives every release |
| Asset scope | Schwab API (partner tier) excludes futures, forex, crypto | Crypto-native: deposits on 8 chains, prediction markets on crypto, stocks and macro events |
Claims about the TDA/Schwab API status reflect public reporting and Schwab's own developer documentation as of August 2026. If Schwab ships a retail API tomorrow, wonderful — you'll still have two.
