Total volume across the 24-hour window reached 185,477,000.2 and notional turnover (high × volume) approximated $178,809,572. Price action was bearish, with a sharp correction observed around 22:30 ET and a consolidation attempt in the final hours.

Structurally, key support levels were identified at 0.91 (tested multiple times) and 0.8953, where price bounced three times in the last 3 hours. A notable bearish engulfing pattern emerged on the 15-minute chart at 22:30 ET, marking the start of a significant downward leg. Resistance levels at 0.95–0.96 failed to hold despite multiple attempts to reclaim those levels in the afternoon. A morning doji around 0.9357–0.9384 suggested indecision but was quickly broken on the bearish side.

The 15-minute 20SMA crossed below the 50SMA around 22:45 ET, confirming the bearish momentum. On the daily chart, the 50DMA sat at ~0.938, while the 200DMA hovered near 0.928—both above current price. MACD showed a bearish crossover on the 15-minute chart at 22:30 ET, while the histogram expanded during the steep decline. RSI hit oversold territory below 25 at 03:45 ET but failed to generate a strong bounce.

Bollinger Bands showed a moderate contraction around 19:00 ET followed by a violent expansion as price fell below the lower band by ~2.2 standard deviations at 22:30 ET. This expansion confirmed heightened volatility. Volume spiked during the decline, aligning with price action. However, at the 0.8953 support level, volume weakened despite price bouncing slightly, indicating potential exhaustion in the short-term bearish trend.

Fibonacci retracements on the 15-minute swing from 0.9657 to 0.8510 showed key levels at 38.2% (~0.923) and 61.8% (~0.896). Price stalled at both levels with weak volume, suggesting they may act as temporary floors. On the daily chart, a 61.8% retracement from the recent high aligns near 0.894, which appears to be the next key psychological level.

Backtest Hypothesis
The backtesting strategy under consideration involves a 15-minute RSI-based mean-reversion approach. It enters longs when RSI falls below 25 and closes above 50 on the next candle, and shorts when RSI rises above 75 and closes below 50. Given the multiple oversold readings in this 24-hour period, particularly at 03:45 ET and 05:45 ET, the strategy would have triggered multiple long signals. However, the failure of those levels to hold—despite volume confirmation—suggests the need for additional filters such as trend alignment with moving averages or divergence checks. Integrating the 50SMA as a trend filter could improve signal quality in this volatile pair.
