Dear sir,
Is it possible to operate 2 - 3 at once. For example if I am buying shares for my friends and family members then I would like to login in one account and place orders using there client id’s… as you place orders for the people who call and trade…

To place orders on behalf of other clients, you require a dealer terminal. At Zerodha, we do provide dealer terminals but for personal use only. To be eligible for the terminal, you require being registered as an authorized person with us and you also require to have an NISM Series VIII certification.
