I have answered this many times on the thread before
@REY619. I guess we'll write this on our website soon too.
- Yes, you can link a third party demat account. However, by doing so you will be allowed to trade in the intraday equity segment only. You cannot do delivery trades through a linked demat account (Other than IL&FS - ISSL).
- If you want to invest (Take delivery), then you must open a demat account with IL&FS (ISSL).
- Very soon, we will have our own demat license too.
Hope this clarifies.
