Stock became illiquid delivery-to-delivery after I bought it for BTST

Yesterday, I bought RCOM with the intention of intraday trading or BTST. There was no warming while buying it. Today when I tried to sell it, kite says that stock is illiquid and delivery-to-delivery only. :o

Where can I read about upcoming changes in stock so I stay away from such stocks?

While trying to buy itself Nudge will show.

It’s showing today, but if I remember correctly, there was no nudge yesterday at the time of buying.
