I'm experimenting with a standard deviation exploration but I'm
getting discrepencies in the resulting answer. Take Alcoa for
example. I get a 5 day Sd of 67 in Amibroker but a SD of 65 in
Excel. I tried this over 5 & 10 day periods for other stocks and
got conflicting answers as well. Is it because AB is a "moving"
standard deviation?
