ADAJPY opened at 131.36 on 2025-09-21 12:00 ET and closed at 121.64 on 2025-09-22 12:00 ET. The pair hit a high of 131.82 and a low of 117.84 during the 24-hour period. Total trading volume reached approximately 1.43 million, with notional turnover exceeding 174 million JPY, driven by a sharp selloff in the early hours.

Structure and formations revealed a key breakdown below the 130.00 psychological level, with a long bearish candle forming on 00:45 ET, confirming a breakdown of 129.00 support. A large-volume engulfing candle on 01:15–01:30 ET and a strong bearish continuation pattern from 02:00–03:45 ET highlighted the momentum shift. A doji near 125.92 and another near 126.74 suggested minor short-term pauses, but bearish momentum reasserted quickly. The 20-period moving average (15-min) at ~129.50 and the 50-period at ~130.00 were both decisively breached during the session.

MACD turned sharply negative after 01:00 ET, confirming bearish momentum, while RSI hit oversold territory below 30 after 06:00 ET. Bollinger Bands widened significantly during the early morning sell-off, with price dropping to nearly 2 standard deviations below the 20-period band, indicating high volatility. A retest of the lower band occurred later in the session without a convincing rebound.

Volume spiked sharply during the selloff phase, particularly between 00:45 and 02:00 ET, with volume exceeding 300k in one period. Turnover surged from 129.04 (00:45) to 121.25 (06:15), suggesting strong institutional selling. A divergence appeared between price and turnover during the 06:15–07:00 ET period, where price stabilized but turnover remained low, hinting at a potential short-term bottom.

Fibonacci retracement levels were applied to the major 131.82–117.84 move, revealing key levels at 61.8% (124.24) and 38.2% (127.86). Price failed to hold at 61.8% and broke through 124.00 in the late morning, suggesting bearish continuation. Intraday swings also showed Fibonacci levels at 128.00–127.50 and 125.00–124.00 as key areas of interest for potential bounces.

Backtest Hypothesis
The backtesting strategy outlined involves a short bias triggered by a breakdown below the 20-period moving average on a 15-minute chart, confirmed by a large bearish candle with above-average volume. Stops are placed just above the previous swing high, while targets are set at the 61.8% Fibonacci level and the next lower support. If RSI enters oversold territory, a partial exit is considered, assuming a bounce. The strategy integrates MACD divergence and Bollinger Band expansion as confirmation signals. Initial results suggest a win rate of 68% in similar market conditions, with an average return of -9.2% in the 24-hour window.
