Dogecoin/Yen (DOGEJPY) opened at ¥29.69 on October 19, 2025, and closed at ¥30.07 as of 12:00 ET on October 20. The pair reached a high of ¥30.59 and a low of ¥28.97 during the 24-hour window, reflecting a 6.4% rally. Total volume was 6,033,726 DOGE, and notional turnover hit ¥186,163,000, with the highest 15-minute turnover recorded at ¥25,049,000 during the final candle of the period.

Over the past 24 hours, DOGEJPY has shown a strong bullish bias, with price finding support around ¥29.50 and building a series of higher highs and higher lows. A critical breakout above ¥30.00 in the early hours of October 20 marked a turning point, with the 20-period EMA crossing above the 50-period EMA to confirm the shift in sentiment. The 50-period moving average currently sits at ¥29.92, and the 200-period MA at ¥29.64, suggesting a clear short- to medium-term bullish trend. The pair has spent much of the session above both key moving averages, reinforcing the upward bias.

On the momentum side, the RSI has moved into overbought territory at 67, indicating strong buying pressure but also a risk of a near-term pullback. The MACD histogram has expanded positively, with a bullish crossover forming around 02:00 ET. This aligns with the price breakout and suggests that momentum remains on the long side. However, the RSI and MACD have not shown strong confirmation of exhaustion, so caution is warranted if overbought levels persist for extended periods.

Bollinger Bands have widened to 3.2%, indicating rising volatility, which has been driven by the late-night rally and a dip into the lower band during the overnight session. Price has spent the final hour of the 24-hour window trading near the upper band, suggesting potential for continuation if buyers remain active. Fibonacci retracement levels suggest that ¥30.25 (61.8% of the most recent bearish swing) and ¥29.90 (38.2%) are critical watchpoints for immediate support and resistance. These levels may offer clues about the strength of the ongoing move.

Backtest Hypothesis

Given the observed patterns, including the bullish breakout above ¥30.00, the doji-star-like candle at 02:30 ET, and the strong alignment of momentum indicators, a potential backtest strategy could focus on entries following confirmed breakouts above key moving averages or Fibonacci levels. Specifically, using the 20-period EMA as a dynamic support line, the strategy could look to enter long positions when price closes above the 50-period EMA and the MACD confirms with a positive crossover. Stop-loss placement could be set at the recent swing low near ¥29.64 or at the lower Bollinger Band. Target levels could be set using the 61.8% and 78.6% Fibonacci extensions of the most recent bearish swing, with trailing stops applied as the trend continues.

This hypothesis aligns with the technical indicators and recent price action, offering a testable framework for assessing the effectiveness of trend-following strategies in the DOGEJPY pair. If historical data for DOGE/USDT is used as a proxy, this strategy could be implemented with minimal adjustments to account for fiat denomination differences.
