How fast is the square-off on opening?

How fast is the square-off on opening?

I had bought a put priced 17.50 a day before expiry, now before market opens I have decided I want to get out my position on opening. Now i had booked an order to square off at 9:11, will the position square off at 9:15:00 ?

Coz at 9:15:00 price was 8.30,
and at 9:15:02 price was 4.30,
and at 9:15:04 price was 3.15

By 9:16:00 price was 1.50
