If what you are saying is true (hum...), you just got screwed by a group pump and dump scheme.
GNET is just an ECN, not an MM, obviously the big frontrunner uses it to dump shares, some buyers could also use it to buy shares. The buyers and the big seller could be the same person, but most likely not. If you are hoping the action of GNET can give you any hint, you are not likely to find anything meaningful on the buy side.
