Gold XAU oscillating range: 4070 (lower support) ~ 4220 (upper resistance) Strong support zone: 3950–4000, I believe the downside below this level is limited. Market logic: After the sharp drop in September, the market in October has entered a consolidation phase with sideways movement and low-level shakeouts, similar to the structure in July. Previously mentioned: If the 4220 resistance cannot be broken, the market will continue to pull back to test the 4070–4100 range. Trading strategy: In the short term, prioritize treating it as a range-bound oscillation: 4070–4220 back-and-forth trading, avoid premature one-sided bets. Today, prioritize going long around 4112–4080. After the oscillation ends, I lean towards a rebound. Wait for a valid breakout of the range before switching to a trend-based strategy.
