Disagree, MM'ers do WTF they want, they hold and trade shares....how do you explain what happened here last week? Here are time and sales, I got my 77k at .0114 but when price dipped to 80's I did not get filled at my .0102 bid...Fidelity told me the MM may have filled my 114 order without taking it to the exchange? The time and sales also explains how why MM'ers can find and run your stop orders... or those fluke .0001 opens we see sometimes
