  • Please note that the purchase and sale values displayed on CoinTracking already include all fees.

    • In case of a sell, the fee needs to be entered as additional amount on the sell side. (Withdrawal)

    • In case of a buy, the fee needs to be subtracted from the buy side. (Deposit)

  • The fee field is more an informational value for our system, so we can calculate the data for our Fee page.

  • We recommend that you regularly generate backups of your CoinTracking account via Account/Trades Backup.

    • https://cointracking.info/backup_trades.php

  • If you want to backup your account data and store it locally please go to the "Enter Coins" page and choose Export - CSV. For a recovery you can use the CSV Importer.

Weird Intricacies

• Exchange API imports seemingly won't re-import transactions even if you rename the Exchange/Group fields in the data, or delete/use a new API key.
  • The only way to get them to re-import seems to be to entirely delete the data for that exchange, then import it again.
  • Suggest making a backup of trades in CoinTracking first, as well as exporting a CSV of all of your trade data (to manually copy comments/etc over again afterwards)
