If you sell your shares today, you will get the full amount from the sale, immediately for trading. This is called an EPI or Early Pay In. However, you can withdraw it only on the next trading day.
Note:
If you do a BTST trade (Buy Today Sell Tomorrow) or T2T stocks, you’ll get the entire amount only on the next trading day.
Stocks sold for delivery today can be bought back on the same day.
