In a Rolling Settlement trades executed during the day are settled based on the net obligations for the day. In NSE and BSE, the trades pertaining to the rolling settlement are settled on a T+2 day basis where T stands for the trade day. Hence trades executed on a Monday are typically settled on the following Wednesday (considering 2 working days from the trade day). The funds and securities pay-in and pay-out are carried out on T+2 day.
