When I try to import my trades export from One Trading, I get an error:
Unknown file
Unable to import this file automatically. Proceed to the file mapping page to continue the import process.
Workaround
I need to modify the file before importing it to Koinly and add two empty columns:
  • Add column "Price Currency" (no need to add any values in the rows)
  • Add column "Amount Currency" (no need to add any values in the rows)
