BTST related auction and penalty

#1

In BTST, are there chances of auction and penalty for trading in A group shares ?

#2

Yes, possibility of short delivery exists even for Group A shares, but it is highly likely that your broker will buy it in the auction and deliver it to if there is a short delivery.
There won’t be a penalty here but the price at which it is bought in the auction will be higher than the prevailing market price.
