My Koinly account is linked to my Coinbase, Coinbase pro, and Kraken. I used API for Coinbase Pro and Kraken.
In order to use the HIFO method in US tax filing, I understand I have to have the following:
(1) the date and time each unit was acquired
(2) your basis and the fair market value of each unit at the time it was acquired
(3) the date and time each unit was sold, exchanged, or otherwise disposed of
(4) the fair market value of each unit when sold, exchanged, or disposed of, and the amount of money or the value of property received for each unit.
Based on the information Koinly receives from my linked exchange accounts, does my current Koinly account have all the necessary transaction information to meet those four requirements?
