Structure & Formations

Price action showed a strong bullish surge from 16,345,255 to a 24-hour high of 16,538,192, followed by a consolidation and pullback. A bearish engulfing pattern emerged near the 16,450,000 level, which may act as a near-term resistance. Key support levels are forming around 16,350,000 and 16,300,000, while resistance is concentrated at 16,450,000 and 16,500,000. A doji at the 16,443,762 level suggests indecision in late trading.

Moving Averages and Momentum

The 15-minute chart shows BTCJPY trading just above the 20-period and 50-period moving averages, but momentum appears to be weakening. The 50-period MA is at 16,397, and the 20-period is at 16,420, suggesting a potential pullback to the 16,350,000–16,400,000 range is likely. On the daily chart, the price is above the 50, 100, and 200-day MAs, signaling a longer-term bullish trend, but with potential near-term correction.

MACD showed a narrowing histogram and crossed the zero line in mid-session, indicating fading bullish momentum. The RSI reached overbought territory (above 70) during the early surge but has since fallen below 60, suggesting some profit-taking.

Volatility and Bollinger Bands

Volatility spiked sharply from 16:00 to 19:00 ET, with the upper Bollinger Band expanding significantly. Price traded above the upper band during this period before retreating into the middle band during the final hours. The narrowing of the bands after 20:00 ET suggests a potential consolidation period, with a possible breakout to the upside or a pullback to the lower band near 16,350,000.

Fibonacci Retracements

Key retracement levels from the 16,345,142 to 16,538,192 swing include 16,456,819 (38.2%) and 16,413,586 (61.8%). BTCJPY has pulled back to the 61.8% level, which may now act as support. On the daily chart, the 38.2% retracement from a larger bearish move is at 16,390,000, which coincided with price consolidation in the last 6 hours.

Volume and Turnover Divergences

Volume was highest during the 17:30–19:30 ET period, with notable spikes at 17:30 and 18:30 ET, supporting the price surge. However, volume dropped sharply after 20:00 ET, despite continued price gains. This divergence suggests weakening conviction in the bullish move. Turnover was highest at 17:30 and 18:30 ET but declined significantly after 21:00 ET.

Backtest Hypothesis

A potential backtesting strategy could focus on detecting the bearish engulfing pattern near 16,450,000 and using it as a sell signal with a stop just above the 16,500,000 level. A target could be set at the 16,350,000 support level, with trailing stops placed near the 16,400,000 level. This approach could be tested over multiple 15-minute candles during high-volume periods and refined to include RSI divergence or Bollinger Band contractions as entry filters.
