No, we aren’t opening trading accounts for minors or below 18 age, because of the regulatory provisions don’t allow stockbrokers to open trading accounts for minors.
As a guardian, you could open a Demat account in the name of a minor and guardian can transfer the securities from his account to his kid’s account as Gift/Donation or transfer between family members. However, such an account will be operated by the natural guardian until the minor becomes a major at the age of 18.
