You are saying that Demat account can be with anyone. But see below, the reply I have received from your customer support when I asked Prostocks beneficiary account details to link my newly opened Prostocks trading account with my already existing Demat account I am having with the DP other than Prostocks.
*Dear Sir,
Please note that you are having only trading account with Prostocks. Easiest service is available for Demat account only, not for trading account.
We cannot allow you to trade in cash segment using other DP account. You will have to open Demat account with us then only we can allow it and there is no account opening charges for Demat account. We are jus t taking Rs.1000/- as deposit which is refundable. So, you can open your Demat account with us and can transfer your all share holding to Prostocks demat account
In case you have any query. Please contact to our support team
