The pair displayed a bearish bias throughout the session, with a strong pullback from key resistance near 3.95 and 3.96 levels.

Structure & Key Levels

Price action revealed a critical bearish engulfing pattern near 3.962, followed by a gradual consolidation phase between 3.92 and 3.89. Support zones emerged at 3.88, 3.866, and 3.851, while resistance held at 3.92 and 3.93. A doji appeared near 3.905 at 04:45 ET, suggesting indecision among buyers and sellers. The 15-minute chart displayed a descending triangle formation, with the lower boundary tightening toward 3.88–3.875.

Short-Term Trend & Moving Averages

The 20-period and 50-period moving averages on the 15-minute chart crossed below key swing highs, confirming a bearish bias. Price closed below both indicators near the end of the session, suggesting a possible continuation of the downtrend in the near term. On a daily scale, the 50-period and 200-period moving averages also crossed bearishly, with the latter acting as a key resistance level in the $3.90–3.92 range.

MACD, RSI, and Momentum

The MACD histogram showed a consistent decline throughout the 24-hour period, with bearish momentum building after the 19:30 ET time frame. The RSI dipped below 30 in the latter half of the session, indicating oversold conditions and the potential for a short-term rebound. However, price failed to break above the 3.90–3.92 level, suggesting that the bearish trend may not yet be exhausted.

Bollinger Bands and Volatility

Bollinger Bands displayed a notable expansion, particularly between 17:30 and 22:30 ET, when price traded near the upper band before retracting. The last few candles saw a contraction in volatility as price drifted closer to the lower band, signaling a potential reversal or a continuation of the bearish trend. Price closed near the lower band, reinforcing the bearish setup.

Fibonacci Retracements and Key Levels

Applying Fibonacci retracements to the 15-minute swing from 3.964 (high) to 3.851 (low), the key levels of interest include 3.922 (38.2%), 3.903 (50%), and 3.884 (61.8%). Price found temporary support at 3.884 before breaking it, suggesting further downside potential toward 3.851. On the daily chart, the 3.90–3.92 area represents a critical psychological and Fibonacci level (61.8% of the prior bearish move), which has so far failed to hold.

Volume and Notional Turnover

Volume remained robust throughout the session, with notable spikes occurring during the bearish breakdown from 3.95 to 3.90. The largest single 15-minute turnover spike occurred at 22:30 ET with a $2.8M notional trade, coinciding with a breakdown of the 3.93 support. However, volume did not confirm a strong rebound attempt after 04:30 ET, suggesting waning bullish interest. A divergence between price and volume was observed in the final hour of the session, with price falling despite a moderate increase in volume, indicating potential bearish exhaustion or a temporary consolidation phase.

Backtest Hypothesis

Given the bearish engulfing pattern and the confirmed breakdown below key Fibonacci levels, a backtest strategy could be designed around a short entry at 3.90–3.905 with a stop-loss above 3.922 and a target at 3.865–3.851. This setup leverages the confirmed bearish momentum, oversold RSI levels, and strong volume confirmation during the breakdown. The strategy could be tested using a 15-minute candlestick time frame, focusing on entries after key support levels fail and divergence between price and volume becomes evident. If price remains within the Bollinger Band contraction at the session's end, a short-term reversal may occur, providing a low-risk re-entry for short-term traders seeking to capitalize on the bearish bias.
