I'll leave the pro trading analysis to jcw,
But it looks like all this volume was just cross trades simultaneously performed on both exchanges, and similar in number of shares too, odd really.
Maybe someone is trying to give the appearance of a selloff?
Well, if so, and they are trying to scoop up a few more shares from weak hands, I think the volume since then is telling them, listen, whoever is left is probably not gonna sell anywhere near this level. So, give it up. Either blow the share price to 5 cents, or start moving it up.
Its like us retail shareholders are in a poker game where we are the really short stack, and the big stacks are going all in, and we call with our small stack, because well, we just wanna see the final hand and take our piece of the pot and move on to the next hand.
Cheers,
