A long upper shadow on the 21:15 candle indicated rejection at 20.89. A doji formed at 22:30 ET, suggesting indecision before a retest and breakdown of 20.76.

Moving Averages and Momentum

Short-term 20- and 50-period moving averages on the 5-minute chart shifted from bullish to bearish bias during the late ET selloff, confirming the breakdown. RSI surged into overbought territory above 70 during the 21:00–22:00 window before diving below 30 by 02:00 ET, signaling exhaustion and a shift in momentum.

Volatility and Volume

Volatility as measured by Bollinger Bands expanded sharply during the 21:00–22:00 ET window, coinciding with the peak and subsequent breakdown. Volume was relatively light before the surge in the 21:15–21:30 candle, where 8,865 units traded. A divergence between volume and price was visible in the 06:30–07:30 ET window, where higher volume failed to support a bullish breakout.

Fibonacci and Key Levels

A 61.8% Fibonacci retracement of the 20.73–20.89 move aligned with the 20.81–20.82 level, which acted as a short-term resistance. Price broke below 20.76 during the 22:15–22:30 ET window, forming a key support at 20.73–20.74, where it consolidated overnight.

The market appears to have transitioned to a short-term bearish bias following the breakdown of key support at 20.76. Investors should monitor the 20.73–20.74 level for a potential rebound or further decline. A sharp rally without strong volume support could signal a false bounce.
