If you want to use a spreadsheet formula instead of another study, try this:

Assuming you have a chart bar timestamped with 09:30:00, you can use this formula, e.g. in cell U3:
=IF(MROUND(FRACTIME(A3),1/86400)=TIMEVALUE("09:30:00"),B3,U4)

This rounds the Time of the DateTime to 1 second, then compares it to the timevalue of 09:30:00.
If they are equal, it persists the Open price until the next 09:30:00.
