1st of all u have to get these from ur data provider for proper tick calculation
1) your data provider must provide tick-by-tick data.
2) you need to save the data in a tick database in AmiBroker, which means that in menu File > Database Settings you need to set the base time inerval to Tick.
but no data provider in India provides such data
