odd. dan, weren't the silver and copper margin increased already, just about a month ago? didn't have much effect then ... maybe that's the reason for further increases ...

TJ,
While I seem to vaguely remember reading something to do with copper margins, I'm reasonably sure that the silver margins have remained unchanged for the year and a half that I've been trading the PM's.
It was about a year ago when the crooks at the COMEX raised the gold futures margins to their present levels which, imo, aided and abetted the near $70 break in the PoG that helped get the screwed commercials unscrewed.
Did you know that the COMEX is the only US Exchange that is still operating under the abbreviated trading schedule that was instituted immediately after the 9-11 tragedy?
