I would say it's something much bigger than flippers. I had a big order in @ 3 & they wouldn't fill. The MM's were stingy w/ the 4's, they wanted to close @ 5. I only see that action when some news is coming. Especially taking into account the low OS it appeared the lower entry points were locked up. SIRG traded like something big was coming next week. Could I be wrong? Yes, but from past experience I'd say something good is happening w/ SIRG.
