Describe the problem:
I just want to clarify for the manual market price edit, what date should I use? Using the transaction date might seem wise, but would be different from the current market price. The only resolution I could think of is just using the cost basis of the sent tokens.
Which exchange/wallet is this regarding?
Almost all of the API based wallets
How did you import data into this wallet?
API
What have you tried to fix this so far?
Changing the market price to the cost basis
