I don't think it was a retail sell. I watch L2 pretty often a big ask shows up and VERT tries to walk it down took out a couple of big ask the last few days they panicked and went higher.
After hitting .11 VERT came again and the ask showed and they pretty much flushed it.
How it is legal for them to do this is beyond me sooner or later they will be forced to cover we just got more eyes on this now.
