The Federal Reserve's interest rate meeting will be held soon. If the result of the meeting is a decision to raise interest rates, then the non-ferrous metal commodities suppressed by the strong dollar will be exhausted. If the result of the meeting is to decide not to raise interest rates, then short-term non-ferrous metal futures will also rebound, so no matter what the outcome of the interest rate discussion, it will be conducive to the bottoming out of non-ferrous metal futures.
