For Coinbase Prime, the files that need to be imported are:
- "orders_Default Portfolio" file
- "transactions_Default Portfolio" file
Please import each file via Custom Exchange Import with the following settings:
"orders_Default Portfolio" file
Import this file twice because the fee is in USD so the trade can be USD purchases or USD sales. (reason for this explained here: Entering Fees)
BUY-side (selling USD)
SELL-side (purchasing USD)
"transactions_Default Portfolio" file
Please save each setting by clicking on the "save" button after putting the file format and parameters exactly as shown in the screenshots. Later, you can just load the saved setting when importing other Coinbase Prime files in the future.
