MRP AGRO IPO Query

This was listed in BSE on 18th Feb.
My query is : In this Open = High = Low = Close is been shown all throughout the day till current date.

Which seems like there are no buyers or sellers in this, just the price movement is occuring based on demand supply gap.

But, in the volume section it can be seen 3k Volume or likewise is there.?

So, can any one tell why and how did it happen ? Or my understanding is wrong in this?
