I was using AI to test SPY. At first I did it manually with a spreadsheet and downloaded monthly data from Yahoo. The monthly data for my starting point on 9/3/2002 had yahoo monthly data of close 81.79 adjusted close 70.36.

When I used AI the data pulled for 9/3/2002 was 75.60. Why the difference.

Is AI set up to pull adjusted close or close.

I really expected either 70.36 or 81.79 and was suprised to see the 75.60?

PS I went and check yahoo again and got the same thimg for monthly data but when I check daily data the 75.60 showed up as the adjusted close for 9/3/2002. But I was asking for monthly data the the program pulled daily data. Why would they be different?
