Looks like someone trying to keep the 013 -016 spread active. Bid whacking away at all bids above the 013.. Keeping a constant sell on 016. Will not go until we have news, increased volume.
It's hard to say. Usually M&M's will work together to lower price after a recent run in order to cover their naked shorts. But, one can never know what's happening for sure behind closed doors. M&M's trade behind closed doors with security that comes close to that of important diplomats according to an ex M&M I knew before his death. Information is highly guarded due to the insane amount of money that changes hands on a daily basis.
Think about this, I have seen interviews with almost all of the markets most important players over the years. But I have never seen an interview with an active M&M or yet to see the inside of their fortress.
