OR, perhaps rather than being a capper the wall at $0.255 is simply a new resistance level. There was a good 5-10 mins where (on CommSec) the total number of shares to sell on each line going up to $0.30 was in the mid six figure range (not million range). No major sell orders at that time. And no one ploughed through $0.255 even though it looked so easy.
Fact is there were no big buyers supporting the SP today. And $0.255 is a new resistance level as the SP follows the wedge trajectory towards $0.23.
