Not at all. You have to inform your CRM that you are going to short xyz stock for delivery. Shorting is different than buying. You can buy any stock with available margin. You can shortsell also but on intraday basis. Shorting for medium or long term has to be arranged. Because you are selling something which you do not own, so you have to borrow the stock from either your broker or any friend and make delivery. Naturally if you are borrowing something you have to pay interest on that. The broker or friend will ask you for how may days or weeks or months you want to remain short and accordingly they will charge you the interest. After the agreed period you will have to buy back the stock and return it to lender.
