If a user has sold any of the holdings, the respective quantity will be displayed under the Trades-->Holdings page.
E.g. Client A has 100 quantities of Reliance in his Demat holding on the current day. He performs a sell trade for 40 quantities.
Now, once the user navigates to Trade-->Holdings, his holdings will display the updated total quantity for Reliance as 60 (Sold quantity - 40)
Also, for better understanding, the user can access the History section, to check all transactions performed on the Holdings for that day.
