What is BTST in trading?

Buy Today, Sell Tomorrow or BTST in trading is a trading facility wherein traders can sell the shares before delivery (or before the shares are credited in the demat account).

In the normal trading process, shares are credited in T+2 days with T being the day of order execution. You cannot sell shares before delivery in normal trading. However, with BTST, you can sell shares the same day or with T+2 days. This helps traders to benefit from short-term price surge in the stocks.
