Yes to the first question. If a stock is trading at $10.00 on 12/1/2000 and the ex-date for a $1.00 quartely cash dividend is 12/2/2000, I would expect the stock to open at $9.00 on 12/2/2000, all else being equal. I believe to correctly test a trading system, the price history for 12/1/2000 should be adjusted from $10.00 to $9.00. Additionally, all prices prior to 12/1/2000 should be adjusted down by the same factor. Am I wrong? Further, why would you adjust prices for special cash dividends but not ordinary quarterly cash dividends - seems inconsistent both logically and economically.
