Total volume reached 55,436.5, and notional turnover hit 27,413,469.2 Yen in the 24-hour window. The pair navigated a volatile 15-minute session with a strong intraday high at 485.9 and a pullback toward key support levels in the 479.6–480.2 range.

Over the last 24 hours, SUIJPY tested multiple key levels and displayed a range-bound structure between 475.0 and 485.9. The 483.3 level, a prior high, acted as a temporary resistance, while the 479.7–480.2 zone emerged as a strong support cluster. A 15-minute bearish engulfing pattern formed around 2025-09-27 09:00 ET, hinting at a potential short-term reversal, though this was later invalidated by a rebound. A small doji at 2025-09-27 05:45 ET suggested indecision in a key consolidation phase.

The 20-period EMA on the 15-minute chart sat around 481.5, while the 50-period EMA hovered near 482.0—suggesting mixed short-term momentum. MACD showed a bearish crossover earlier in the session but faded as price found support. RSI topped near 75 at 484.8, a classic overbought level, but failed to follow through with a strong rally. Bollinger Bands had a mild contraction from 06:00 to 09:00 ET before expanding again, with price closing near the upper band at 481.59, indicating some bullish pressure.

The 15-minute volume profile showed significant spikes at 484.81–485.72 and 480.2–481.44, but volume failed to confirm a sustained breakout above 483.3. Notional turnover was also uneven, with a divergence visible in the late morning as price moved higher without a corresponding volume spike. This suggests a potential lack of conviction among buyers and could lead to a near-term pullback if key levels fail to hold.

Fibonacci retracements applied to the 475.0–485.9 swing showed 61.8% at 483.0 and 38.2% at 480.8, which aligned closely with observed price action. These levels acted as dynamic supports and resistances, particularly the 480.8 level, where a strong bounce occurred mid-morning. The 483.3 level, which overlaps with the 61.8% retracement, could be a critical point for the next 24 hours, depending on whether buyers re-engage or sellers take control.

Backtest Hypothesis
A potential backtest strategy could involve using the 50-period EMA and a 20-period EMA crossover as a trigger for entries, combined with a stop-loss placed just below the 479.7 support level. Given the observed RSI overbought readings and the bearish engulfing pattern, a sell signal could be generated when price breaks below the 480.8 Fibonacci level and the 20 EMA crosses under the 50 EMA. A take-profit could be placed at 478.5–478.6, aligning with previous consolidation. This approach would aim to capitalize on the bearish momentum observed in the late morning and early afternoon, while controlling risk with a defined stop.
