The answers to your questions in respective order are as follows-
1. Currently only one broker can be connected with one Tickertape account at a time, therefor importing holdings from another broker is not possible at current stage. We are considering this as a feature request and have added this into our feature requests list.
2. As of now only stocks (except BSE only) and smallcases can be imported into Tickertape portfolio, we are working towards adding more options such Mutual funds, BSE only stocks in our future releases.
3. If you mean "Notification Alerts" by this, it's not available currently but it definitely seems like an interesting add-on for us, we have added this into our features requests list where it can be considered for future releases.

Yes! Its a feature that we definitely want to develop in the near future. We'll surely keep you posted in case of any updates.
