So, The zero column is the index, What I did here is I selected all the indexes in df having dividends and stock splits
The 1,2 columns show the stock open and close price data, 5 and 6 column shows the dividends and stock splits data of the company
So, using 1,2,5, and 6 columns I want to calculate the adjusted closing price, which should be exactly or very similar to 3 column "adj close" price.
Basically, What I want to figure out is
"adj close" = Some_Mathematical_Formula_Using("open", "close", "dividends", "stock splits")
If the formula answer matches with the given "adj close" column data then I'll be using the same formula for calculating "adj open"
Please use the below data to use the formula and above data to get total dividends and stock splits data
