Ethereum/Yen (ETHJPY) opened at 625,051 on 2025-09-24 at 12:00 ET and peaked at 625,828 before plunging to a 24-hour low of 586,657. The pair closed at 597,350 on 2025-09-25 at 12:00 ET, marking a bearish 5.3% move.

Structure & Key Levels

Price formed a strong bearish engulfing pattern during the early morning hours in New York and Tokyo, confirming a breakdown from the 600,000 support level. A 61.8% Fibonacci retracement of the 625,828 high to the 586,657 low is near 599,000, now acting as a potential short-term support. The 500,000 psychological level remains a key long-term downside target.

Moving Averages and Momentum

On the 15-minute chart, the 20-period and 50-period moving averages are in bearish alignment, with price trading well below both. The daily chart shows the 50-period SMA at ~603,000 and the 200-period at ~620,000, both acting as overhead resistance. MACD is bearish with a negative histogram, and RSI has dropped to oversold levels (~28), suggesting potential for a rebound, though momentum remains decisively to the downside.

Bollinger Bands and Volatility

Bollinger Bands widened significantly through the late night and early morning trading hours, with ETHJPY frequently testing the lower band. This expansion reflects heightened volatility and the potential for further price extremes in the near term. The price closing near the lower band reinforces bearish momentum and suggests that volatility may persist in the next 24-hour window.

Volume and Turnover Dynamics

Volume surged dramatically as the breakdown from 600,000 occurred, with the final three 15-minute candles showing average volumes exceeding 100 ETH per candle. Notional turnover followed in lockstep, confirming the bearish move. No major divergences were observed between price and volume during the decline, indicating continued conviction in the downtrend.

Fibonacci Retracements and Trend Context

Applying Fibonacci retracements to the key swing high at 625,828 and the recent low at 586,657, the 38.2% level is near 607,000 and the 50% level near 606,200. Price may retest these levels before resuming the bearish trend. On a daily basis, a breakdown below 586,657 could trigger a 61.8% retracement to ~556,000, though near-term support is expected around 599,000.

Backtest Hypothesis

A potential backtesting strategy involves entering short positions when price closes below the 20-period moving average on the 15-minute chart, confirmed by a bearish engulfing pattern and a MACD crossover below the signal line. The stop-loss could be placed just above the 600,000 level, with a take-profit target aligned to the 50% Fibonacci retracement at 606,200. This strategy relies on the integrity of the bearish breakdown and could be tested on similar ETHJPY movements in recent cycles.
