This?
"Just so everyone knows thats my .031 for 100k for over an hour now. When the bid was dumped on and hit .031 I was the big on the bid and none of my share were filled."
Happens all the time. Yes, it does not seem fair, but it doesn't have to be nefarious!
If someone had a AON buy order for 100k in before you, it wouldn't show, and if someone put in a 100k sell, they would match and your bid would be ignored.
Remember, what appear to be MM actions are almost always actually the actions of traders routing orders through the MM's... there isn't some evil dude wearing a MM shirt sniping trades. Maybe an evil trader, but not a MM!
