python DataReader for getting past stock data.
I heard that
Adj Close data could be different each other if data range is different between datas. This is because (as I know of)
Close data is adjusted based on the LAST DATE of period.
APPL1_data : 2010-01-01 ~ 2016-01-01 adj close data
APPL2_data : 2014-01-01 ~ 2016-01-01 adj close data
But as I compare these datas by myself, both have same
Adj close datas even though ex-dividend, stock split have happend during this period.
Did I miss something?
