leinad,
with every sale is a buy.
if you look at trading pattern for oppies and shares, NO BUYERS on screen but heaps of sellers. sellers get itchy (remember ppl prob holding since minimum june this year for results etc),
but then BANG, some oppies and shares get snapped up and its in the green. the next day in the red. force more sellers on, then bang in the green again.
tells me a lot
