Core time-in-force choices

A GTC limit order rests until it fills or is cancelled. ALO is post-only: an ALO order that would immediately match is canceled instead. IOC executes what it can immediately and cancels the remainder.

A market order expresses urgency, not a guaranteed price. Its realized slippage depends on depth and volatility. The maker/taker fee is only one component of that choice.

Chase orders reprice in the browser

A Chase order is an ALO limit order that automatically reprices toward the best bid or ask until it fills or stops. It remains post-only and normally rests one tick inside a multi-tick spread, or at the best bid or ask when the spread is one tick.

The automation runs in the browser tab that created it, and the official interface currently allows up to five active Chase orders. Closing the tab or losing connectivity changes the operational risk, so monitor the order rather than treating it as server-side certainty.

Stops and take-profits

Stop-market and take-market orders trigger into market-style execution; stop-limit and take-limit add price control but can remain unfilled. Triggering does not guarantee the final fill price.

Mark price behavior matters because robust pricing is used for risk and trigger logic. Verify trigger basis in the current interface and use reduce-only when the instruction is meant only to close.

TWAP and scale orders

A scale order distributes multiple limits across a price range. TWAP suborder intervals depend on order size and duration, with a minimum of 30 seconds. Each suborder has a 3% maximum-slippage constraint. Missed slices can make later suborders larger, capped at three times the normal slice size.

The current interface can randomize each TWAP slice by up to ±20% and delay activation until a trigger price. The interface can also terminate at a maximum or minimum mark price. TWAP is visible onchain, can finish incomplete and is not an anonymity tool.

Choose from urgency and failure mode

Ask which failure is worse: no fill, partial fill or adverse price. The chosen failure mode should drive time in force. A low maker fee is irrelevant if missing the trade violates the strategy; immediate execution is costly if the book cannot absorb the size.

Frequently asked questions

Is a Hyperliquid Chase order server-side?

No. The official interface says Chase repricing runs in the browser tab that created it. Closing the tab or losing connectivity can interrupt the automation.

Does a stop-market trigger guarantee the final fill price?

No. A stop-market instruction prioritizes execution after the trigger, but volatility and book depth can move the realized price. A stop-limit controls price more tightly but can remain unfilled.

What happens if a post-only ALO order would cross the book?

The ALO order is canceled instead of matching as a taker order.
