Intraday and BTST are not permitted in Rights Entitlements, these are settled on a Trade-To-Trade basis, so can only sell them once these have been credited to your Demat account.
Also the Pricol RE’s will be traded on the exchange only until 11th December, after these you will not be able to sell the RE’s and will have to apply for Rights Shares, if you fail to apply you will lose all the money paid to purchase the RE’s as this will be extinguished once Issue closes.
