Cancel all open orders for a specific market and/or asset.
Cancellation requests require L2 authentication headers: KUEST_ADDRESS, KUEST_SIGNATURE, KUEST_TIMESTAMP, KUEST_API_KEY, and KUEST_PASSPHRASE.
At least one of market or assetId is required. The response always returns HTTP 200 OK. Successful cancellations append the ULIDs to cancelled. If any order cannot be cancelled, it appears in notCanceled with a short reason string.
