What is BTST (Buy Today, Sell Tomorrow)?

BTST stands for Buy Today, Sell Tomorrow. It lets you sell shares the very next trading day even though they have not yet reached your demat account.

This is possible because India uses a T+1 settlement cycle. When you buy shares on Day 1 (T), they are credited to your demat on the next trading day (T+1). BTST allows you to sell those shares on T+1 while they are still moving through the clearing process.
