Structure and candlestick patterns show that key support levels are forming near 7.2e-07–7.3e-07, with 7.5e-07 acting as a key intermediate resistance and 7.7e-07 as a recent high. A bullish breakout candle was observed on the 15-minute chart at 2025-09-20 07:15 ET, followed by a bearish retracement at 08:45 ET. No definitive reversal patterns (e.g., engulfing, doji) were identified, but the pullback suggests a potential for retesting the breakout level. The 20- and 50-period moving averages on the 15-minute chart converged near 7.35e-07–7.4e-07, offering a dynamic support area.

Momentum indicators showed a divergence between RSI and MACD. RSI dipped below 30 in the final hour, signaling oversold conditions, while MACD remained near a zero cross, suggesting neutral momentum. The pair traded within a narrow Bollinger Band range for most of the session, with the breakout and pullback causing a modest expansion. Price closed near the middle band, indicating no strong bias toward either direction.

Volume and turnover spiked dramatically during the breakout at 07:15 ET and again at 08:45 ET, confirming the strength of the movement and the pullback. However, volume declined sharply in the final hours, suggesting exhaustion or consolidation. Notional turnover was in line with volume, offering no clear signs of divergence. Fibonacci retracement levels from the breakout high (7.7e-07) to the low (7.3e-07) indicate potential support at 7.47e-07 (38.2%) and 7.39e-07 (61.8%), which may serve as near-term pivots.

Backtest Hypothesis
The backtesting strategy involves entering long positions on bullish breakouts of the 15-minute Bollinger Band upper band, with a stop-loss placed below the 20-period moving average and a take-profit target set at the 61.8% Fibonacci retracement level of the breakout swing. Given the recent breakout and pullback, this approach may offer a defined risk-reward profile if the pair holds above 7.3e-07 and shows renewed momentum. The strategy could be tested using the breakout at 07:15 ET as the entry trigger and evaluating the subsequent pullback at 08:45 ET as a potential exit point.
