stock circulation during ban

I was learning about ban on stock. And I read that when a stock is under ban you can’t open new position but you can square up your position. My doubt is that if no one can open new position how can someone can buy my future if I sell them for square of my position.

One can have sell position other may have buy, so both will place their bid and offer.

if I am selling means some other have buy it means he is opening his new position which is not allowed on stock under ban.

can you explain in deep please.

He is short and is buying back, closing his position. Seems you are new to markets, I would suggest you to read varsity here before trading in fno.
