All I know is, if it is questionable whether they are playing by the rules or not, it doesn't hurt to report to FINRA. They'll then watch it, and question them on it, which grabs them by their tidy-whities. OTOW had lots of the ask never changes, and other things, WAS average volume of 2 million a day. I'm only seeing volume of 50,000 this morning. MMs are playing nice with them now.
