Why no one bought this option?


I am talking about USDINR 22 Mar 68.75 CE . Today USDINR March 19 ended at 69.00, making this option well in the money by 25 paise, yet no one purchased this option and this expired at 0.0025. Why?


I think it has something to do with STT. Can someone please explain?


Ok. So I realized that it expired at 12:30 PM at 0.0025
