The selling patterns seem to reflect the fact that a seller or sellers want to get off a position without driving the price down. They are patient and basically sell into any buying that appears at their price. If it were shorting, I would expect them to at some point, try to knock the price down to cover. the buyers are getiing all they want in the .53 - .55 range. They seem to want to move the price higher but the sellers are more than willing to accommodate their bids.
