Just an observation - I've been staring at the Level 2 for weeks - Cantor has been showing a 100 lot but buying literally hundreds of thousands of shares for at least a week or so. There could be 50-75k on the offer at 1.39 and it gets taken all at once with Cantor showing a 100 lot on the bid at 1.39 in its place.
Again, could be utterly meaningless, someone(s) covering a bunch or someone(s) accumulating a bunch...but figured I'd mention for those who care...either way the potential energy being stored, once kinetic, will be interesting to watch.
