As per the exchange regulations, only registered clients of a Stock Broking platform see the live data of prices from the Stock Exchanges. To make the exchange data feed real time, you will have to be a registered active client of Dhan investment platform.
When you are registered on Dhan, you are not a client till your account is created by verification of KYC, signing of the Account Opening Form and then registering you as a client with the Stock Exchanges. Until the time your account is not fully registered with exchanges successfully, till that time the stock prices you see on the Dhan app or website will be delayed. On completion of the same, all information will be shown in real-time.
