  title: Backpack Flatten Open Orders on a Market
  summary: List open orders on a market, cancel them all, and confirm none remain.
  description: >-
    A risk-control flow for the Backpack Exchange. It lists the open orders for a
    single market, cancels every open order on that market, and then re-lists the
    open orders to confirm the book is clear for the account. Every step inlines
    its request — including the ED25519 signing headers required on authenticated
    calls — so the flow can be read and executed without opening the underlying
    OpenAPI description.
