1.Service Details

For transactions outside of our supported exchanges, transactions between individuals, and transactions that cannot be retrieved by file or API, you will need to manually add your own transaction history.

This service will create a custom file on your behalf, which is one of the ways to manually add transaction history.

For more information on custom files, please see Custom File for any other trades.

 

2.Recommended for

Those who find it tedious to create their own custom files.

Example: You have a lot of experience with transactions where the file downloaded from the exchange does not contain the transaction details or where the API does not deliver the history.

5.To Be Prepared by the User

The file must contain information that will enable a third party to determine what kind of transaction it was when he/she checks the file (e.g., "transaction date and time," "transaction type," "currency name," "volume," etc.). If such information is not provided, we may ask the customer to confirm the details of the transaction.
