In Amateur Invest you can have multiple portfolios in use, and in this window you can manage portfolios (create and delete). Please note, that portfolios and bank accounts are managed together, so that when you create and change portfolio, you'll also create and change bank accounts.
In the list the possible portfolios are shown: The "Calc" column is not in use yet, Name (3 characters), and the date for the first and last buy/sell in the portfolio.
Enter a 3 character code to create portfolio. You'll then be asked if you wish to copy the current portfolio. Choose "yes" to copy data from the current portfolio or "no" to create an empty portfolio.
Enter a 3 character code to delete portfolio.
