Buying or selling at open price

I want to buy/sell futures at exact opening price but most of the time when trading opens at 9.15,the price would have moved far away from open price within 1 second. how to buy axactly at open price… will AMO help or any other solution.

NaMasTe TraDeR,

No matter what order type you use, amo, preopen etc, It is just not possible to buy exactly at the open price for highly liquid scrips.
