What does AB do when it gets data from Yahoo? I periodically load historical data to make sure my database has been updated to include splits and dividends.
I am trying to update a spreadsheet to use the updated data that includes the dividends. I wrote an AFL program to dump the open on the trade date. I saw that the field values were quite different than the value when I actually traded it. My question is when getting historical data from Yahoo, what does AB or AQ do when it sees an adjusted close? Does AB change all fields, the OHLC, by a proportion of delta or does it just change the close value? Thanks, Barry
