Dai/Yen (DAIJPY) opened at 151.97 on 2025-10-10 12:00 ET, reached a high of 179.86, dipped to a low of 151.17, and closed at 152.53 at 2025-10-11 12:00 ET. Total volume across the 24-hour period was approximately 1,396,303.57 units, with a notional turnover of roughly $214,489,757 (assuming 152.53 average rate).

The price action displayed a volatile bearish breakout early in the session, dropping from ~152.2 to ~151.17, only to rally sharply afterward with a large bullish engulfing pattern at 19:30 ET. This suggested a temporary reassertion of bullish sentiment after oversold conditions. The price then consolidated around 152.2–152.8, indicating possible short-term equilibrium. Key support levels at 151.51 and 152.03 held firm, while resistance was observed at 175.18 and 153.49.

On the 15-minute chart, the 20-period and 50-period moving averages crossed multiple times, signaling a churning market. RSI dipped below 30 twice, indicating oversold conditions, though the price did not reverse decisively each time. This suggested divergence between momentum and price, with bearish exhaustion possible but not yet confirmed. MACD showed a weak bullish crossover post-19:30 ET but failed to maintain bullish momentum, with the histogram shrinking quickly.

Bollinger Bands expanded during the sharp sell-off, with price touching the lower band at 151.17, while the upper band expanded to 179.86, illustrating high volatility. The bands then contracted toward 152.2–152.8, signaling a possible reversal into a consolidation phase. Volume increased during the breakdown and breakout phases but declined afterward, suggesting a shift in institutional participation to retail activity.

Backtest Hypothesis
The backtesting strategy described focuses on capturing momentum-based reversals using a combination of RSI divergence and Bollinger Band breakouts. In this case, the sharp dip below 152.03 followed by a bullish engulfing pattern and RSI crossing above 30 at 19:30 ET would have been a potential entry trigger. If executed with a stop-loss just below 151.51 and a target near 153.1, the trade would have captured most of the consolidation phase’s upside. However, the divergence in MACD and weak volume post-breakout suggest that the strategy may need a filter for volume confirmation to avoid false signals.
