The Demat Debit and Pledge Instruction (DDPI) is a document that gives the stockbroker limited authorization to process transactions smoothly without requiring repeated authorizations.
If your DDPI is mapped to your account, you can sell your holdings without a prompt asking you to authorize the transaction.
DDPI serves as a secure, regulated, and efficient way to allow brokers limited access for essential functions while safeguarding investors' assets and maintaining regulatory compliance.
