If you want to delete an empty and unused portfolio, you can do so in your online account (desktop) by opening the portfolio, then go to 'Options' and select 'Delete portfolio' (see video below).
Please note: If you have an empty portfolio that has been funded and traded, you can not delete this portfolio. We are soon to release a feature where clients can 'Hide' empty portfolios that have been funded and traded.
Please keep an eye out on our Community page for more updates on this.
