  title: Kraken Cancel and Replace a Spot Order
  summary: Inspect an order, cancel it, then place a replacement order.
  description: >-
    A reprice flow for the Kraken Spot REST API for cases where an in-place
    amendment is not appropriate. It queries the existing order, cancels it, and
    on a confirmed cancellation submits a fresh order with new terms. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
