I have a question too but dont want to unnecessarily create a thread for it.
We often hear that sub brokers trade the shares in demat account without the consent of the client. Is this practice also done by 3 in 1 trading accounts like icici, idbi,pnb?
Also when a person is doing intra day trading with margin then is it possible that the broker may sell off his other securities in case of a loss or is it so that at the most the person can lose the money he had put in for margin. Say Rs. 100....margin 5....so Rs.500...so at the most he can lose just Rs. 100 or even Rs. 500?
