When I import my KuCoin CSVs, Account History Cross Margin is rejected with message:
This file is not needed, upload other files from your Billing History
But this file contains my margin loan and later liquidation of my collateral (Borrowing History file is empty)
Workaround
I need to modify the Account History Cross Margin file before importing it:
  • Delete all transaction rows except for ones with type
    Borrowings
    and
    Liquidation Custody
    and
    Liquidation Rollback
  • Rename

  • After importing, merge all the transactions related to the same liquidation (e.g. all withdrawals with the rollback deposit) together Ref. How to merge/split transactions manually | Koinly Help Center
