Kindly refer this link on Zerodha website:
MIS (1x) allowed on all stocks except for those on this list (https://docs.google.com/spreadsheets/d/1-T6RlEE8Gn2fioep_Cmdx9ECRX_WpQbfJJfsU8PdOV8/edit#gid=0)
Why is this so? Please do not say having enough funds is the answer because this list of intraday trading disallowed stocks exists in and of itself. Any help would be deeply appreciated.
