According to this...:-

...COMEX finishes trading at 2.30pm, so presumably price used to settle the options contracts is the price at that time?
By a strange coincidence the price at this time was $1162 (as predicted by Puzz) and, immediately after 2.30pm, the gold price took off like a "NASA space launch".
If this is not blatant manipulation then I'll eat my hat.
