Your risk limits

Every order — from chat, from the ticket, from a close button — passes through one policy check before it reaches Hyperliquid. There is a single call site for it in the codebase, so there is no path that skips it.

The limits are yours. taker does not impose a house risk policy; it enforces the one on your account.

The defaults

A new account starts here:

Limit	Default	What it stops
Max per order	$5,000	One oversized order, fat-fingered or misparsed
Max open notional	$25,000	Total exposure across all positions
Max leverage	10×	Leverage beyond your intent
Daily loss limit	$1,000	A bad day becoming a worse one
Daily notional traded	$50,000	Runaway churn
Max slippage	50 bps	Filling far from the price you saw

These are a starting point, not a recommendation

$1,000 of daily loss is a real amount of money. If that is more than you want exposed on a bad day, lower it before your first trade — tightening a limit is instant and needs no signature.

Changing them

Limits live in Settings. Two rules govern changes:

• Tightening is instant. Lowering a limit, or turning on reduce-only mode, applies immediately with no extra step. Someone reaching for the brakes should never be asked to sign first.
• Loosening requires a fresh wallet signature. Raising a limit is a privileged action, so it needs proof you are present and it is really you. This is what stops a stolen session from quietly raising your ceilings and then draining the account through “legitimate” trades.

Reduce-only mode

A switch that permits closing but refuses opening. Useful when you want to wind down without the temptation — or the risk — of adding. It is also what taker falls back to automatically if it cannot confirm your jurisdiction, so a degraded state never traps you in a position.

What happens when an order breaches a limit

It is refused before it reaches the venue, with a message naming which limit it hit and what would fit instead. Nothing partial executes.

The chat also sees your limits when constructing an order, so it will usually propose something that fits rather than something that gets rejected — but the engine is the authority, not the model. A model that ignored your limits would simply produce a proposal that fails.

Daily counters

The daily loss and notional limits reset at 00:00 UTC, not local midnight or a rolling 24 hours. The counters are atomic, so two browser tabs confirming at the same moment cannot both slip through a limit that only one of them fits.
