I guess my point is that ‘buy by number of shares’ is not a feature we’ve ever had in the app. It has always been buy by amount of cash, sell by no of shares. Not ideal.
Giving the user an option to buy by no of shares or cash, and being able to sell by no of shares or cash, would be a new feature to the app. I think it is something you will see in the not too distant future though, along with more order types
