Client shall be allowed to revoc scrips only if:
Scrips are available under demat holdings and are authorised from CDSL
No order is pending for the scrip in the order book.
Not a single quantity is executed on the scrip on that day.
Eg. Suppose, client has authorised below scrips on CDSL
Now, here clients are allowed to revoke the authorisation for Infosys and SBIN scrip only.
If a client cancels the pending order for Reliance and TCS, he/she shall be allowed to revoke authorisation for TCS scrip only as no quantity was traded for TCS on the day. For Reliance, revocation shall not be allowed as 4 quantities were traded.
