Can I be assigned before expiry?
Indian equity/index options are *European-style* — exercisable only *at* expiry — so early assignment generally isn’t a concern here (unlike American-style options elsewhere). The main settlement risk in India is *physical* settlement of ITM stock options at expiry, which is why closing them beforehand (unless you want delivery) is the key discipline.
