Some Kraken futures limit orders can still execute after a successful cancellation if the cancel arrives during the Maker Protection hold window. Kraken expanded the system on Oct. 8 , bringing that order-handling rule to more contracts.

Kraken completed Phase 2 after announcing 61 additional perpetual contracts. Maker Protection applies to selected futures markets; Kraken’s documentation describes an initial 20-millisecond hold.

Maker Protection holds orders that can take liquidity before they reach the matching engine, giving traders with resting orders time to react. A limit order without a post-only instruction is held on a covered market even if it would otherwise have rested on the book.

A cancel inside that window changes what the order may leave behind. Kraken converts the held placement to immediate-or-cancel, meaning it can trade when released but cannot leave an unfilled remainder on the book. The original hold expiry stays the same.

For example, a trader submits a non-post-only limit order and cancels before the hold expires. The cancel request bypasses the delay and converts the held placement to immediate-or-cancel. At the original release time it can still fill; any unfilled amount is discarded.

Kraken reports those instructions separately. The cancel receives success with order status “cancelled,” while the order later reports its own fills or failure to execute. For a converted limit that cannot trade, the REST v3 response is iocWouldNotExecute .

Kraken’s instruments feed identifies each market’s configured hold through makerProtectionMillis . Its documentation says an absent or zero value means no configured delay.

The distinction is contract-specific, so traders cannot infer coverage from the coin name alone. Kraken says its ten most liquid linear perpetual markets are excluded and spot trading is unaffected. Standalone post-only placements bypass the hold. Cancel requests also bypass it; a held limit placement still waits for its original release time.
