Structure & Formations

The price action displayed a bullish reversal from 05:00–07:45 ET, with a strong breakout above the 0.7513–0.7525 resistance zone. A large bullish engulfing pattern formed between 07:15 and 07:30 ET, suggesting short-term buyers had control. Key support levels include 0.7400 and 0.7350, both of which have historically contained downward moves, with 0.7400 showing strong rejections. A 61.8% Fibonacci retracement of the 0.7319–0.7539 move aligns with the 0.7455 level, which held on multiple occasions.

Moving Averages and Momentum

On the 15-minute chart, the 20-period and 50-period SMAs were closely aligned in the $0.7400–$0.7440 range, with the 20-SMA crossing above the 50-SMA after 06:00 ET, signaling a potential uptrend. The 50-period SMA on the daily chart is at $0.7385, suggesting a bullish crossover may be forming. RSI climbed above 55 to 61, indicating increasing momentum, while MACD crossed above zero at 06:30 ET and remained in positive territory, supporting the bullish bias.

Bollinger Bands and Volatility

Bollinger Bands widened as the price moved above the upper band between 06:15 and 07:45 ET, signaling strong buying pressure. The volatility expansion suggests a continuation of the current trend is likely. Price is currently trading near the upper band again, which may act as a dynamic resistance level.

Volume and Turnover

Trading volume surged after 07:15 ET, with over 312,595.64 units traded in the 07:30–07:45 ET candle, confirming the bullish breakout. Notional turnover increased in tandem, with no signs of divergence between price and volume, reinforcing the strength of the move. The 07:15 ET candle showed a sharp reversal and high volume, indicating accumulation or strong institutional interest.

Fibonacci Retracements

Applying Fibonacci to the 0.7319–0.7539 swing, key retracement levels include 38.2% at $0.7431 and 61.8% at $0.7495. The price bounced off the 61.8% level at 07:30–07:45 ET, suggesting it could be a potential consolidation zone. On the daily chart, the 61.8% retracement from a larger move may provide near-term resistance at $0.7550–$0.7570.

Backtest Hypothesis

A potential backtest strategy could be built around the breakout of key Fibonacci retracement levels, particularly the 61.8% support and resistance zones. Given the current context, a long position entering on a confirmed close above the 0.7525–0.7539 range with a stop below 0.7500 may be viable. The MACD and RSI divergence can be used as early signals to validate the breakout, while the Bollinger Bands provide a dynamic context for entry and exit levels.
