hyperliquid-advanced

# Hyperliquid advanced actions Uses the same header as `hyperliquid-orders` (`info`, `exchange`, `ACCOUNT`, `round_px`, `round_sz`, `new_cloid`). Everything that signs is Execution Trader only, on a ticket. ## Dead-man's switch (`scheduleCancel`) Tells the exchange to cancel **all** of the account's open orders at a future time unless you push the time out or clear it. Useful when the desk runs a watch that could die while resting orders sit on the book. The user asks for it explicitly; the report states the time. ```python from hyperliquid.utils.signing import get_timestamp_ms res = exchange.schedule_cancel(get_timestamp_ms() + 10 * 60 * 1000) # 10 minutes out; must be >= 5 s in the future res = exchange.schedule_cancel(None) # clear it ``` TypeScript: `await exchange.scheduleCancel({ time: Date.now() + 600_000 })`; omit `time` to clear. Limits: at most 10 triggers per day per account (resets 00:00 UTC). It cancels stops too, so re-arm protection if it fires. ## TWAP Splits a size into slices at fixed intervals (30 seconds minimum) over `m` minutes: 5 minutes to 7 days per the docs, though the TypeScript SDK's schema caps `m` at 1440 (24 hours), so longer runs need the raw action. Minimum 100 USD total; each slice capped at 3% slippage; `t: true` randomises slice sizes by up to 20%. Not in the Python SDK's high-level `Exchange`; use TypeScript or the raw action. ```ts const twap = await exchange.twapOrder({ twap: { a, b: true, s: ...
