I hope you can help. I am new to CiviCRM and writing a custom Summary Field.

I have written the new field and the trigger, but I am confused about how this will count all of the values for before today. Is there a place in the extension I need to include another query? Is there other magic I am missing?

Thanks, Penny

When you go to Administer menu » Customize Data and Screens » Summary Fields, the last option is When should these changes be applied?. Your summary fields will be primed at the time selected. If you want to look at the code, the function is sumfields_gen_data.
