Although Stock Portfolio Organizer has very powerful data import functionality, you may still find yourself entering data manually. When entering data manually, mistakes are easy to make and surprisingly many portfolio management software packages available will not allow you to make certain changes once a trade is entered, has been partially sold or sold completely. This can make fixing errors extremely time consuming as you will have to delete and enter trades again. This is not the case with Stock Portfolio Organizer as it has been designed to give you maximum flexibility when editing existing trades. Not only can you edit the quantity, transaction date & time etc of a trade after it has been sold but you can also undo a share split or even edit the original quantity of a trade before a split. Stock Portfolio Organizer will automatically adjust the current quantity to what it should be with the split applied. Great huh?
