That's 2days in a row of that 911 trade ... it may be signal amongst the MMs, but I don't know what it means. I used to think it meant news coming, but that hasn't happened.
And trading certainly has an appetite for .0006s. Picked up some on the Ask, then twice I placed orders for .0006s as Bid support, and both times they were filled fast.
The way it's trading today, it appears as if it's "coiled" and primed for [good meaningful] news -- and any substantial buying pressure will move this North a few ticks (since the BMIC & VNDM "wall" seems to not be playing today) ... just my impression.
