WOW! How dare you accuse me of assuming?
What I have done is look at the price action and trading volume and inferred that it is likely that someone is putting in "all or nothing" orders for 200,000 or more shares at a time . If you have a broker with access to powerful software he should confirm what I have deduced with my free charts and graphs.
I see the bid/ask at $0.069/$0.07, sometimes for hours , then all of a sudden 300,000 gets bought at $0.07.
To me that suggests the market maker is picking up small sells at $0.069 then turning them over at $0.07 when he has enough to fill a large AON order.
The fact that small orders are frequently at a lower price, but large orders are at a higher price should be all the convincing you need. As for my high school Economics book, I sold that for half price years ago , but any similar book should work. Check the appendix under supply/demand.
If you're still not convinced, check the on balance volume.
P.S.
I would have replied yesterday, but....you know.
