TooComplexException is not a skill issue.
It's a ceiling.
The useThinkScript community has 21k+ developers working around a language with no API surface, recursion limits, and studies that break when the desktop updates. EventTrader starts every free account with a documented REST API, SDK and MCP server.
A real retail API, day one
Documented REST API with key auth on free signup — docs at /api-docs, SDK at /sdk, plus an MCP server (pip install cymetica-eventtrader-mcp).
Webhook auto-execution
Point any alert at your personal webhook endpoint and it executes on the exchange account you connect — your keys, encrypted, used for your authorized trading only, never withdrawals. Delivery is retried and confirmed: the venue's acknowledgement of your order, not a promised fill.

Clone working strategy bots from the marketplace and run them server-side — or drive your own through the API.

- No programmatic API — thinkScript cannot be driven from outside the platform
- TooComplexException and recursion limits cap what studies can express
- thinkorswim now runs under Charles Schwab, which took over TD Ameritrade and is folding the platform into its own offering, so the platform's direction is Schwab's to set, not the scripting community's
The full Schwab-migration story — including the TDA API sunset — is on /thinkorswim.
What you'd actually be trading here
EventTrader is a prediction exchange: perpetual prediction markets on crypto, stocks and macro moves with no expiry, live central-limit order books, event markets on real-world outcomes, and a marketplace of trading bots you can clone instead of coding. Position risk is capped at what you put in — no liquidation engine, no margin calls. Server-side alerts and free webhook auto-execution come with every account.
- Free means free. No card required. Nothing auto-converts into a paid plan.
- We are not a drop-in replacement for your old stack. EventTrader is a prediction exchange with a real public API — the automation is familiar, the markets are ours.
- No predictions sold. Markets are markets; we make no performance claims.
- Leave in one click. Withdraw on-chain any time, with a tx hash you can verify.
