Coin Trade Ledger is a custom-built calculation engine that calculates cryptocurrency tax profits and losses with incredible detail and accuracy. Coin Trade Ledger allows you to upload your data to generate profit & loss tax reports. This will allow you to see exactly where your position for each trading account, each instrument, and your entire portfolio. Upload data via file upload (csv), Excel, or API (we connect directly with the exchange for you). Reports include support for trades, deposits, and withdrawals. Unfortunately, no. We won't allow you to import the same data set twice. If we suspect that a record may be duplicated, we will notify you and you have the option to either keep it or delete it. Our price archive includes minute-to-minute trade data on currencies and assets. This means that when we do a price search, it is the most accurate price.
