Structure & Formations

The 15-minute chart displayed a classic bullish engulfing pattern following a sharp decline from 20.55 to 20.42 between 17:30–18:45 ET. This was followed by a consolidation phase with key support forming at 20.48–20.49 and resistance at 20.51–20.53. A notable bearish divergence appeared on the RSI during the late afternoon, hinting at potential short-term fatigue in the upward move. A key 61.8% Fibonacci retracement level at 20.51 was tested twice but failed to break convincingly.

Moving Averages

The 20-period and 50-period moving averages on the 15-minute chart were closely aligned, indicating a lack of clear trend. The 50-period MA (20.5) acted as a pivot point. On the daily chart, the 50-period MA (20.49) and 200-period MA (20.52) were in a near-crossover configuration, suggesting a possible short-term shift in bias toward a potential downtrend.

MACD & RSI

The MACD histogram showed a sharp positive divergence during the afternoon rally but faded into a negative trend by the end of the session. RSI reached overbought territory (75) around 17:45 ET, indicating potential exhaustion. It later declined to neutral territory by the 12:00 ET close. This suggests that the upward momentum was strong but not sustained, and buyers may need stronger conviction to push past 20.55.

Bollinger Bands

Bollinger Bands showed a moderate expansion during the midday volatility, reaching a 0.03 range width (20.53 to 20.50). Price action spent a significant portion of the session within the middle band, suggesting indecision. A contraction phase occurred in the late evening, indicating potential accumulation ahead of the next move.

Volume & Turnover

Volume spiked sharply during the 17:30–18:45 ET window, reaching 84,960 units, suggesting large orders or algorithmic activity. Turnover also surged during this time, indicating a high degree of conviction in the price movement. A divergence appeared in the evening hours, where volume declined while price continued to consolidate, signaling potential fading interest from active traders.

Fibonacci Retracements

Fibonacci levels were applied to the 20.42–20.55 swing. The 61.8% level at 20.51 and 38.2% at 20.49 acted as critical psychological levels. Price tested 20.51 twice but failed to break through, indicating strong resistance. A breakdown below 20.48 would target the next Fibonacci level at 20.46, reinforcing the bearish bias.

Backtest Hypothesis

A potential backtesting strategy could involve using the 20-period EMA as a dynamic support/resistance trigger in combination with RSI overbought/oversold conditions. For example, a long entry could be initiated when price pulls back to the EMA and RSI turns from oversold to neutral, while a short position may be triggered when RSI exceeds overbought levels and price breaks below the EMA. The 17:30–18:45 ET rally aligns with this pattern, showing a strong EMA retest and overbought RSI, which could have signaled a potential reversal.
