Volume of shares for sale under 64c hasn't changed since open (~7-8 million) so the sells are being placed above 64c and out of play to put pressure on those sitting on the fence.
Looks like people are happy to sell & buy at this level which is a good medium. LOL.
Who knows what is real in the stack and what is not. As said already by others I think it is best to only take notice of those placed within 0.5-1.5c of current price and ignore the rest. Most other buys/sells outside this range are either props or hopefuls and get moved as the SP moves. The real buying & selling that really effects the SP gets done at market.
So far looks like the pressure on the sell side is working but I would not want to be out of SDL for even a minute over the next 3 months.
