You can open your portfolio directly in the app. To do this, click on 'Future' - 'Tomorrow Fund' - 'Invest' in the menu bar and you will be guided step-by-step through the process.
Opening the depot is possible for existing customers and new customers alike. Re-identification may be necessary. The next step is to query your knowledge and experience with securities.
Finally, your data will be checked and forwarded to lemon.markets to open a depot. The opening will be confirmed after about one or two working days and you can now order your first investment.

Please note: Your Tomorrow checking account is used to offset your deposit. So you first need a checking account in order to open and use the depot.
