[amibroker] Adjusting for dividends

["Barry Scarborough" <razzbarry@xxxxxxxxxxxx>]

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
