Question : Intraday Quotes

The attached mdb contains intraday quotes for the S&P 500 on a minute basis. My goal is to build a new tabel which contains for each date the %-performance between two fixed times e.g. between the Open price at 9:30:00 AM and the close at 10:00:00 AM.

E.g. the Open at  04/08/1997 9:30:00 AM was 762.22 and the Close at 04/18/1997 10:00:00 AM was 760,03. Then the new table should contain -0.29%(=760.03/762.22-1) as value for the field %-performance for the 04/18/1997.

Any suggestions how I can do that with SQL?
