Buying shares on upper circuit

How to buy shares which keep hitting upper circuit everyday before u know it?

Hmm… there is no guaranteed way. The best bet is to place an order as AMO or place it yourself when market opens for pre-open at 9am. This way you will maybe be ahead of others in the queue to buy, so if someone sells you will hopefully get it.

But if no one is selling, no way to get the shares.
