Midterm elections (starting November 3rd) - not presidential election; Friday's non-farm payrolls (affecting December rate hike expectations); this wave is just a correction after a sharp drop, not a trend reversal. Long positions should not be held. Wait for the bullish trend to continue. Final judgment: • Short-term resistance: $3980-$3990 • Mid-term watershed: $4200-$4220 - a firm hold above this level confirms the end of the decline. Short-term trading: A slight rebound is possible during the daytime session after Friday's sharp drop. If it fails to break through $3980-$3990, further declines are expected. Medium-to-long-term: Currently in the allocation range; buy in batches as prices fall. The higher the cost-effectiveness, the more risk-rewarding the strategy. Avoid panic selling at low prices. Short-term: Long positions can be taken based on the $3925 support level, with a stop-loss at the previous low of $3880.
