can't delete stock
In the app and on the website, if a stock is no longer available (ie. stock has been taken off the market or changed symbol and the old symbol does not exist), there is no way to remove it from any list (custom list of my portfolio).
As the stock symbol has been removed from the exchange (ASX or TSX), in yahoo finance, you can no longer click (ie. https://au.finance.yahoo.com/quote/) to view details about that stock, thus, you cannot remove the star (that is used to add/delete from a list).
How can I remove a stock from a list of the stock doesn't exist anymore?
