AMO order doubt?

[fno_Q]

What happens to AMO orders if it is not executed before 9:30?

Think is for MIS orders only get cancelled at 3.20pm by admin , if it was CNC will be carried till 3.30pm. Also If there is gap up in preopen , your amo sell order will get executed at 9.08 am itself at higher gapup open price , viveversa for amo buy orders
