You got a lot to learn about Market Makers, no offense or anything, but the "Market Makers" are not going out and buying shares and holding the price down and bid wacking... The market makers are controlled by who ever is using them... IE I could get on NITE or HDSN my self and lower the ask to 1.25 or what ever, and stack a bunch of shares on it. Or I could get on bid, and up tick it, etc. When you see that happening thats not he "market makers" doing it, it's what ever stock trader that is using that market maker doing it.
So please, don't blame the market makers, blame the traders who are using them, as they are the ones controlling how this, and every other stock trades. The market makers are simply "there".
