Why is each Poloniex export limited to 1 year?
Why is each Poloniex export limited to 1 year?

Troubleshooting
Transactions are missing after upload
Transactions are missing after upload
Check that all six report types were exported and uploaded. If records from specific years are missing, confirm each file covers the correct date range and re-upload the missing files together with the rest in one KoinX session.
Older transaction data is not appearing in KoinX
Older transaction data is not appearing in KoinX
Ensure each CSV file covers the full date range of your history. Since each export is limited to 1 year, you need one file per year per report type. Export the missing year and re-upload all files together.
CSV file won't upload to KoinX
CSV file won't upload to KoinX
Re-download a fresh copy of the file directly from Poloniex without opening it. Opening the file in Excel or Google Sheets reformats date and number columns, breaking the file structure KoinX expects.
Futures PNL trades are missing from KoinX
Futures PNL trades are missing from KoinX
Confirm the Futures PNL History CSV was exported and uploaded. This file is separate from Spot Orders and must be downloaded independently from Activity -> Futures -> PNL History.
Borrowing or repayment records are missing
Borrowing or repayment records are missing
Confirm both the Borrowing and Repayments CSVs were exported from Activity -> Spot Orders -> Borrowing and Repayment respectively, and uploaded alongside the other five files.
KoinX is showing duplicate Poloniex transactions
