I'm not sure why there are 1's being sold when 2's

I'm not sure why there are 1's being sold when 2's keep getting bought. It doesn't make much sense, maybe I'm missing something. It's just that this thing bounces between 2's and 3's more often than 1's and 2's. Glad I made a small profit last run, but I still have a million free shares that I would like to see move up a bit.
