Describe the problem:
Kraken and Bittrex demands according to your API reference also imports from CSV. Namely old transfers (to get the right total balance) from Bittrex and fiat related imports for Kraken (namely Ledger.csv).
Which exchange/wallet is this regarding?
It applies at least to:
How did you import data into this wallet?
Mainly with API and the delta that was missing (according to your “stated limitation”) also with the CSV.
What have you tried to fix this so far?
I can’t manually match them up. Its seem the system dont get it. Overlapping imports should be matched with a certain heuristic to be the exact same thing: Overlapping data is wrongfully double. And hence double tax. I can’t deleted just one part and not consider the other part.
A fix would be to match up date/time (some csv have timezone shift), amount (some csv truncate, API rounds certain digits), currency pair, fees,… with a heuristic because they will be 99.99% identical and obvious to the human eye.
