Example prompts

- "Check BTC-USD on the 1-hour chart. If RSI is oversold near support, buy $2,000 worth on my crypto account."

Safety

- Virtual money only — no deposits, withdrawals, or broker connection.
- Server-side prices — fills use live market data fetched at execution time; the model can't invent a fill price.
- User-scoped tokens — stored as SHA-256 hashes, every call verified against the token owner's accounts, revocable in one click.
