Just trying to sell a few Rolls Royce but it only allows Buy only
If those Rolls-Royce shares are held inside a Pie, that would explain why you’re only seeing the Buy option.
When shares are bought directly in a Pie or imported into one, the Sell button does not appear on the instrument page. To sell them, you can either use the Pie’s Withdraw option or Export the investment from the Pie via the three dots in the top-right corner.
