Bitcoin/Yen (BTCJPY) opened at ¥16,955,381 and traded as high as ¥17,092,591 before closing at ¥16,643,873 at 12:00 ET. The 24-hour low was ¥16,327,174, with total volume of 152.69 BTC and a notional turnover of ¥2,728,087,345. Price action displayed a significant breakdown following an initial bullish attempt.

Structure & Formations

Price formed a bearish engulfing pattern as it reversed from a key resistance level near ¥17,090,000. Earlier in the session, a bullish breakout occurred but failed to hold, indicating a loss of buying momentum. A descending triangle structure was also evident as price consolidated lower, with support levels forming around ¥16,600,000 and ¥16,500,000.

Moving Averages

On the 15-minute chart, the 20-period and 50-period moving averages crossed below the price, signaling bearish momentum. The 50-period MA on the daily chart also crossed below the 200-period MA, reinforcing the short-term bearish bias in a broader timeframe.

MACD & RSI

The MACD crossed into negative territory during the breakdown, confirming the bearish reversal. The RSI, which had reached overbought levels during the initial rally, dropped sharply below 50, indicating a strong shift in sentiment. These indicators suggest that further downward movement is likely unless a large bullish reversal forms.

Bollinger Bands

Volatility expanded significantly as price moved from the upper to the lower Bollinger Band. The breakdown occurred after a brief consolidation period inside a narrowing band, which often precedes strong directional moves. The current price sits near the lower band, suggesting further downside risk if the trend continues.

Volume & Turnover

Volume spiked during the breakdown, confirming the bearish reversal. Notional turnover also increased sharply during the decline, aligning with the price move. However, during the failed bullish breakout earlier, volume was relatively low, indicating weak conviction in that move.

Fibonacci Retracements

Applying Fibonacci retracements to the recent swing high (¥17,092,591) and swing low (¥16,327,174), price has retraced 61.8% at ¥16,600,000. A close below this level could trigger a 100% retracement at ¥16,327,174, or potentially test the ¥16,000,000 level. Key support levels at ¥16,500,000 and ¥16,400,000 align with the 50% and 38.2% retracement levels.

Backtest Hypothesis

Given the failure of the bullish breakout and the confirmation of the bearish engulfing pattern, a backtesting strategy could be constructed using these candlestick signals. If we adjust the symbol query for BTC/JPY and detect bearish engulfing patterns on the 15-minute chart, we can use those events as potential short entry signals. The key is to isolate these events using the raw OHLC data and test their performance under the same conditions observed today. With high volume and a strong RSI divergence, this approach could yield meaningful insights into the market’s behavior under similar setups.
