I think someone has the right idea; bid just ahead
Post# of 22456
It looks like he's trying to run a block w/113000 @ .125 on the bid and 21000 on the ask @ .1695 (VDNM ahead of him w/5k on ask @ .1695)
It would seem like one could sustain more pressure upwards and achieve better buys in the process. If shorting they'd have to raise the bid to cover.
....ears open to those more versed
