You do realize, right, that for every share bought there must be a share sold, and vice versa?
Well, "we don't know" would have been a better answer. I'll have to explore and seek my answer somewhere else.
Thanks for your responses
We do know, the daily bought and sold number of shares is the same.
You're obviously going down the route of the misleading 'more buyers than sellers makes the market move up'. I'd save yourself the fools errand and understand the basic concepts of how trading occurs first.
Why are people skirting around giving me a straight answer?
Nobody is skirting anything. The answer to your question is that bought volume and sold volume are necessarily the same. Thus, the reported volume figure is both shares bought and shares sold.
Obviously, you seem to be looking for something else. Maybe it's a case of terminology confusion. Are you after up volume vs. down volume?
