RE:Options Expiration Day On THe LMETurned out they closed it just under the equivalent of $14,100 USD per tonne. All calls above $14,100 expired worthless and this was likely the "sweet" spot to minimize payout on oustanding put, as well.
Now the real buyers of nickel are no doubt on to these games and will time their buys according to the manipulators schedule. The sale ended today and the LME indicates another 2,000 tonnes went out the door today, for a remaining nickel inventory of 269,898 tonnes.
Or you can just wait until Kitco get updated an look at their graph.
