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.
