I think the 1.4M at 7c was real and it all got sopped up faily quickly by buyers a while back.
I think I just witnessed a broker lurk. A sell order hit for 323M upon whcih many sellers undercut and went out at 6.9c. The 323M was then revised to 323,444. Certainly not a level playing field. Sellers unfaily spooked a bit by it. Why do we have to suffer these low life? How about some fair trading rules?
