I've only found really old posts regarding methods to get the opening price for multiple symbols and could use some guidance on the cleanest/efficient method possible.

In my case, I would like to get the opening price at one minute after market open each day (9:31) for equities from a course & fine universe filter. 

I've thought about using a scheduled event set for 9:31 to save each opening price. Am I headed in the right direction?
