The way we have planned this is that holdings will move out of ILFS and show up in Zerodha the same time. So your trading remains unaffected. If your holdings are pledged for F&O, it can continue to remain pledged. When you unpledge, it will come back to the Zerodha account.
And of course, if we are not able to smoothly transition by the due date, we will extend it. We can’t say 1 year and all, no one will bother to take the effort now.
