Rolling Settlement (RS)- Rolling settlement: means that transactions related to sale and purchase of shares. The transaction has to be completed within a limited period of time – i.e. to reduce the scope for over-speculation and volatility in the market. According to it, a deal has to be necessarily materialised within the stipulated period which at present is T+2 (i.e., trading day + two working days). The transfer of shares is done through the Demat Account rather than physically.
