The history shouldn't be changing, but the current value for A/D will change by the day. It's somewhat volume weighted, and low volume causes different movement than high volume.

There's a formula partway down this page that shows how A/D is computed. The number it spits out isn't shares, it can grow faster or slower than actual shares traded.

I know I used to think of it being measured in shares. I think I've also made a mistake before looking at it in periods other than one day. Pretty sure I read somewhere it loses some reliability when measuring trading session that aren't 1 day each (but don't quote me on this)
