Historical price warnings appear when CryptoTrader.Tax is unable to fetch the historical price of a specific coin.
Why does this happen?
Historical price warnings are not common, but they may appear if:
You are trading an obscure, low-volume coin that is not widely available
The cryptocurrency was transacted before being listed on exchanges or other platforms
You manually entered an incorrect ticker symbol for your coin (ex. BCT instead of BTC)
Your coin went through a "rebrand", and it needs to be re-mapped in the system. For example ETHOS being renamed to BQX. (please contact our support team if your coin needs to be re-mapped)
How can I fix this warning?
You should reach out to the CryptoTrader.Tax live-chat support team if you need assistance retrieving the historical price of your coin. Just use the widget in the bottom right corner to chat with a support representative.
Alternatively, you can manually enter a historical price for your coin if you know what the price of the coin was at the time you were trading it.
To manually edit the historical price of a coin, navigate to the Historical Price Warning tab in Step 3 and click into the Price Warning detail modal.
Within the Price Warning modal, you can manually enter the value of 1 unit of your coin at the particular Timestamp you were trading it.
CryptoTrader.Tax will use the value you manually enter when calculating your gains and losses.
