Transactions on a stock of your portfolio are entered by "expanding" the specific stock in the tree view of the Portfolio Manager's left pane. Select "Trades", then the type of transaction you wish to record: "Buy", "Sell", etc. The list of previously recorded transaction will appear in the right pane. To add a new one simply fill out the fields in the "New" (Buy, Sell, etc.) row. A previously entered transaction can be edited in place by double-clicking on its field or selecting it and typing.
