Thoughts on Price Movements?

I've noticed over the past several months as the SP tries to edge up to and over 10c, a seller comes in and places an order in proportion to the top buyers side volume much lower than current trading price for that day.
Today for example, the price has pushed up to 10c and a new seller has put a sell order for Would this possibly suggest someone is trying to push down the price because of a short position or maybe as part of an accumulation strategy? or another reason, thoughts?

Cheers.
