Trying to find but i can't seem to find where they raised margins in other things 3 times in 5 days and as many times in the last few months. They are losing control and can't deliver so they need some longs to puke out their holdings to cause a waterfall effect so they will be able to cover. They hit the price as Osama is killed and the talking heads say the world is a safer place and voila, silver price is hit.

Price makes commentary.

Quite simple.
