With the introduction of DDPI, only new accounts or non-POA accounts with Arihant Capital will not accept POA as a form of authorization of trades. Instead of POA, you can now use DDPI. However, if your POA is already registered with Arihant Capital (before 31st August 2022), you can continue to use POA as a mode of authorization. Existing PoAs are valid until you revoke them with a POA form and register for DDPI.
