The certified One Wallet software checks each and every transaction if the stock of the corresponding account is enough to serve the exit of the coins. If ‘over stock’ is sold or paid then it indicates that the transaction history is either incorrect or incomplete.
For tax purposes a complete and correct transaction history is necessary for the calculation of acquisition costs and times, it is suggested to supplement the missing history or correct the errors before making the report.
In this case, transactions that are affected will be shown in the missing history area. Also, you can see which asset and how much of it is missing to serve the transaction.
To find the solution to the problem, please check the completeness and correctness of the transaction history and add missing trades to the corresponding account.
