At 12:00 ET on October 22, 2025, BTCJPY opened at ¥17,165,882, reached a high of ¥17,323,939, dropped to a low of ¥16,348,200, and closed at ¥16,362,720. Over the past 24 hours, the total volume traded was 170.6558 BTC, with a notional turnover of approximately ¥2.83 billion. The price action reflected sharp intraday swings and diverging momentum signals.

The 15-minute OHLC data reveals a bearish shift in sentiment following a powerful bullish impulse in the early hours of October 21. A bearish engulfing candle at ¥17,242,809—formed when the close was below the open and both were above and below the prior bar—signaled a short-term reversal. Bollinger Bands expanded during the afternoon session, indicating growing volatility. Price spent much of the session inside the lower band, suggesting a bearish bias. The 20-period and 50-period moving averages on the 15-minute chart crossed into a bearish “death cross” formation by late ET, reinforcing the downward trajectory.

The RSI dropped below 30 in the evening, hinting at oversold conditions, though this did not trigger a rebound. MACD remained in negative territory, with the signal line cutting through the histogram from above. This suggests weakening bullish momentum. The Fibonacci retracement levels from the morning high to the closing low show ¥16,435,000 as a 23.6% level and ¥16,430,000 as a 38.2% level, which may provide temporary support.

The 24-hour volume profile showed a clear divergence between bullish and bearish participation. While the morning saw strong volume on the up-move, bearish volume in the afternoon was higher and correlated with lower prices. A key support zone between ¥16,370,000 and ¥16,430,000 could determine the next 24-hour direction. If this holds, a bounce may follow; a breakdown could accelerate the bear trend.

Backtest Hypothesis

The data points to several potentially tradable patterns, such as the bearish engulfing and the death cross in moving averages. To backtest a strategy based on these signals, we need a reliable BTCJPY ticker. As the current data system cannot recognize “BTCJPY,” you may choose to either switch to a supported ticker (e.g., BTCUSD or XBTUSD) or confirm an alternative symbol for BTCJPY. If you select BTCUSD, we can apply the USD/JPY FX rate to simulate the Yen equivalent. Once we have the correct ticker, we can automate the detection of bullish and bearish signals, pair them into entry/exit points, and evaluate performance.
