As ETRF increased in size at bid .0005, UBSS came in at ASK showing 999,999   .0006    So NITE, UBSS, VFIN are at .0006 blocking.    I wish I had a lot of cash right now to keep hitting the ASK at .0006 .. say 30 million shares.  If they would keep piling it up at .0006 I would keep hitting it.  Gosh that would be a fun day.
