Develop three months of daily,Ir price history from an Internet source (Yahoo, perhaps). Set up an excel worksheet. Put \"date\" in the A1 cell, the higher priced stock {\"Lowes\" for example) in the El cell and the lower priced stock (perhaps "Home Depot\") in the C1 cell. (Elf course, use stocks that you pick.) Cut and paste the dates in the first column and the respective stocks adjusted closing prices in their respective columns. Delete rows that represent stock splits (i.e., where two consecutive mws have the same date}
