October platinum started out the new trading week in close proximity to last Friday's high for the move but some traders feel that prices may be reluctant to climb up into new high ground. Labor unrest in South Africa continues to provide solid support for the market, as the strike has now spread to another key platinum producer in the region. With futures open interest and ETP participation expanding at a large rate, other traders feel that there is rising potential for a sizable pullback in October platinum if the current "risk on" vibe in global markets loses momentum.
