Price Action and 24-Hour Summary

At 12:00 ET – 1 on 2025-09-24, Bitcoin Cash/Yen (BCHJPY) opened at 83,746 and surged to an intraday high of 83,775. However, by 12:00 ET on 2025-09-25, the pair had fallen sharply to 81,400, closing near the session’s low. The 24-hour total volume was 94.83 BTC, with a notional turnover of approximately ¥7,735,987. The price action indicates bearish control and potential exhaustion after a steep decline.

Structure & Formations

The price formed a strong bearish engulfing pattern as it broke below the 83,185 level, followed by a long lower shadow near the close. A doji appeared briefly at 82965–82965, suggesting indecision. Key support levels emerged at 81,394–81,400 and 82,167–82,224. Resistance is found at 82,720 and 83,185. The intraday low at 81,395 could serve as a short-term floor for a potential bounce.

Moving Averages and Momentum

On the 15-minute chart, the 20- and 50-period moving averages trended lower, reinforcing the bearish bias. On the daily chart, price remains below the 50, 100, and 200-period MAs, indicating long-term bearish sentiment. The RSI dipped below 30 during the last 6 hours, signaling oversold conditions, while the MACD crossed below the signal line, suggesting momentum is fading to the downside.

Bollinger Bands and Volatility

Volatility expanded significantly during the 24-hour period, with the Bollinger Bands widening as the price moved from near the upper band to the lower band. The sharp drop into the lower band signals a high-risk area for a bounce or continuation, depending on volume and order flow. A reversal would require a close above the middle band at ~81,897.

Volume and Turnover

Volume spiked during the initial drop from 83,775 to 83,185, with a 3.944 BTC volume candle. However, as the price continued lower, volume remained weak, indicating a lack of conviction in the bearish move. Turnover declined during the last 4 hours of the session despite price falling into the 81,400–81,550 range. This divergence may hint at a potential near-term bottoming process.

Fibonacci Retracements

Applying Fibonacci retracements to the most recent swing high (83,775) and low (81,394), key levels to watch for potential bounces include the 23.6% level (~82,764), the 38.2% (~82,311), and the 50% (~82,585) retracement levels. A close above 82,224 could trigger a retest of 82,720 as a potential near-term resistance.

Backtest Hypothesis

A potential backtesting strategy for this market involves entering a short position when price closes below a key support level (e.g., 82,167) confirmed by a bearish engulfing pattern and a MACD crossover below the signal line. A stop-loss could be placed just above the 20-period moving average, with a target at the next Fibonacci level or key psychological level (e.g., 81,400–81,200). This setup could be tested on historical 15-minute data to evaluate win rate, risk-reward ratios, and drawdowns over similar volatility periods.
