No. BTST facility can only be used if you have a demat account also with VNS.
If I submit the Client Master of my demat account with another DP, can I trade BTST or can I sell a Delivery?
No, you cannot. For these you’ll need to have a demat account with us. Usually opening a demat account is recommended if you wish to trade in cash segment with us.
If you already have a demat account with some other DP, even that can be linked to your trading account with us. However there are limitations with an outside DP demat account. Hence it is preferable to have a demat account with us for a smoother experience.
