$XAG 1. 83.93 Support Effectiveness: If this level is broken with increased volume, it will open up further downside space; if multiple attempts to test it fail to break, a stage bottom may be forming.

2. Volume Changes: Insufficient volume during a rebound is likely a trap for more gains; if volume shrinks during a decline, it indicates exhaustion of selling pressure, increasing the probability of a rebound.

3. Fundamental Linkage: Silver prices are highly correlated with the US dollar index, US Treasury yields, and geopolitical factors, requiring simultaneous attention to macroeconomic changes.
