You have requested that a transaction occur. However, the transaction has not yet been processed by our bank, so you still have time to cancel the transaction.
Your transaction that you initiated has begun, but your bank has not confirmed that the funds have been fully transferred. While your balances may reflect the processing transaction, the funds may not be available to use in the account where they are being sent. Transactions that are marked as processing cannot be cancelled.
The transaction has completed, and funds are now fully available for use in the account where they were sent.
