just saw this headline ...on the wires ...
-NYMEX to change margins for silver, copper futures contracts-
-Washington (Platts)--18Apr2006-
-The New York Mercantile Exchange on Tuesday announced margin changes for
its silver and copper futures contracts, beginning at the close of business on Wednesday.-
-Margins for the silver futures contract will increase to $3,750 from $3,250 for clearing and non-clearing members
and to $5,063 from $4,388 for customers-
ok ... maybe this is a good enough reason for the silver market to pause its parabolic climb
