Ethereum/Yen (ETHJPY) opened on 2025-10-11 at 583,959 yen and closed at 581,182 yen on 2025-10-12. The 24-hour high was 615,575 yen, while the low was 562,738 yen. Total traded volume over the period was 5,107.45 ETH, with notional turnover amounting to approximately 3,000,000,000 yen.

The pair formed a bullish breakout pattern over the last 24 hours, with price moving decisively above a strong resistance level that previously capped the rally. Key support levels include 570,000 yen and 562,738 yen, which held during the early morning pullback. A bullish engulfing candle at 22:30 ET marked a turning point, followed by a sustained rally that pushed price to a multi-day high.

Moving averages on the 15-minute chart showed a clear bullish crossover: the 20SMA crossed above the 50SMA between 10:30 and 11:00 ET. The 50/100/200-day SMAs on the daily chart also turned upward, supporting the breakout as part of a larger bullish trend. Bollinger Bands widened significantly during the final hours of the session, indicating heightened volatility and a breakout that extended beyond the upper band.

MACD & RSI

MACD turned strongly bullish during the final 3 hours of the session, with a sharp upward crossover and expanding histogram. RSI hit overbought territory (above 70) at the peak of the rally, raising the probability of a near-term pullback. However, the sustained momentum and volume suggest strong buying interest, which could push price higher before a correction occurs.

Volume & Turnover

Volume spiked sharply in the last 4 hours of the session, especially between 15:00 and 16:00 ET, where it surged to over 400 ETH traded in a single 15-minute candle. Notional turnover also increased significantly during this period, confirming the strength of the move. No material divergence between price and volume was observed, reinforcing the credibility of the breakout.

Fibonacci Retracements

The 61.8% Fibonacci retracement level of the recent downswing was around 584,161 yen, which was breached with strong volume. The 100% extension is at approximately 617,984 yen, which could act as a near-term resistance target. On the 15-minute chart, the 61.8% retracement of the final leg up was at 593,378 yen, which is a potential short-term ceiling.

Looking ahead, Ethereum/Yen could continue its bullish trajectory if buyers defend the 575,000-yen level on a pullback. However, traders should remain cautious as overbought RSI and widening Bollinger Bands suggest a potential consolidation or correction in the near term. The next 24 hours will be critical for confirming the strength of this breakout and the sustainability of the rally.

Backtest Hypothesis

The described backtesting strategy aims to exploit breakouts from Fibonacci retracements and key moving average crossovers in high-volatility environments. On the 15-minute chart, a long entry could be triggered when the price closes above the 61.8% Fibonacci level and the 20SMA crosses above the 50SMA, with a stop loss placed below the most recent swing low. The strategy would also include a trailing stop at the 38.2% level on the 15-minute chart as a dynamic exit. The recent move aligns closely with this setup, as the price broke above the 61.8% retracement and the 20SMA crossed above the 50SMA. If this pattern holds, the strategy may offer a high-probability trade entry with a defined risk-reward profile.
