Structure and Trend Analysis

Price action displayed a key breakdown below 134,000, confirming short-term bearish bias.

A bearish engulfing pattern formed at the 0700 ET time frame, followed by a long-legged doji near 134,500, signaling indecision. The 20-period moving average dipped below 135,000, aligning with the 61.8% Fibonacci retracement of the 135,633–133,177 leg.

Momentum and Oscillator Signals

The 20-period MACD turned sharply negative, with bearish divergence in line with price declines. RSI dropped into the oversold range, raising the possibility of a short-term bounce. However, given the broader downtrend, a rebound may only offer a temporary relief.

Volatility and Bollinger Band Behavior

Bollinger Bands expanded significantly during the 1500–1600 ET window, indicating rising volatility. Prices closed near the lower band, reinforcing bearish momentum. A period of consolidation or a reversal candle near 134,000 could hint at a potential reversal.

While a rebound into the 134,500–135,000 range appears possible, traders should remain cautious about a continuation of the selloff, especially with volume still trending higher. A breakout above 134,500 could reinvigorate bullish sentiment, but bears are in control for now.
