To have intraday intervals in Bar Replay, you need to have Database settings configured for Base Time interval lower than daily.

As written in the manual: http://www.amibroker.com/guide/h_charting.html

"Changing bar interval (periodicity)

Please note that intraday intervals are disabled if your database is in end-of-day mode. Intraday modes are available only for databases that have "Base time interval" in File->Database Settings set to anything less than end-of-day. If you for example set "Base time interval" in File->Database Settings to 5-minute, all chart periodicities from 5-minutes up will be enabled."
