The price action formed a defined bullish swing from 1.392 to 1.426, followed by a pullback and consolidation near 1.419. A notable bullish engulfing pattern occurred between 17:30–17:45 ET as the pair broke above key resistance, suggesting a short-term shift in sentiment.

Moving Averages and MACD / RSI

On the 15-minute chart, the 20-period SMA rose from 1.398 to 1.413 over the 24-hour period, crossing above the 50-period SMA in a bullish crossover. The 50-period SMA on the daily chart showed a mild upward bias but remained below the 200-period SMA, indicating a longer-term sideways to moderately bullish trend. The MACD turned positive around 17:30 ET as the rally began, peaking at 0.002 before the pullback. RSI climbed above 60 during the rally but has since corrected back toward 55, suggesting momentum is still in favor of the bulls, though with signs of exhaustion.

Bollinger Bands and Volatility

Bollinger Bands showed contraction in the overnight hours between 00:00–06:00 ET, followed by a sharp expansion as the pair moved from 1.403 to 1.426. Price remained within the upper band for most of the afternoon, suggesting increased volatility and momentum. The bands tightened again as price approached 1.419, hinting at a potential consolidation phase before the next directional move. The recent volatility surge could indicate increased participation and potential for a breakout.

Volume and Turnover

Volume spiked significantly during the 17:30–20:00 ET period, particularly around the high of 1.426, with the 17:45 ET candle posting the highest volume of 382,119.56. Turnover correlated closely with the volume, peaking as the price reached new highs. However, in the following hours, volume declined, indicating that the initial bullish move may have been driven by large orders or short-term traders. A divergence between price and volume emerged during the pullback from 1.426 to 1.419, suggesting caution for further upward moves unless volume supports the next rally.

Fibonacci Retracements

On the 15-minute chart, the 1.392–1.426 swing produced a 38.2% retracement at 1.417 and a 61.8% retracement at 1.410. These levels aligned with key support clusters and acted as price anchors during the consolidation phase. On the daily chart, the 1.392–1.426 move retraced back to 1.410–1.415 as of 2025-09-27. The 1.419 close is close to the 23.6% Fib of the daily swing, suggesting that the pair may test this level again for further consolidation.

Backtest Hypothesis

A potential backtest strategy for this pair could focus on a breakout-based system where entry is triggered when price closes above the upper Bollinger Band following a period of contraction, with volume confirming the move. Stop-loss would be placed just below the 61.8% Fib level at 1.410, with a take-profit target at the 1.426 high or the 38.2% Fib at 1.417. The MACD and RSI would serve as filters, with long entries only taken if MACD turns positive and RSI crosses above 50. This approach leverages volatility, volume, and Fibonacci levels to capture short-term bullish momentum.
