BNB/Yen (BNBJPY) opened at 141,121 on 2025-09-26 at 12:00 ET and closed at 145,535 by 12:00 ET on 2025-09-27, with a daily high of 147,706 and low of 141,121. Total volume was 337.81 BTC, and notional turnover reached 48,814,794 JPY. A sharp rally unfolded in the 04:00–06:00 ET window, pushing price above key resistance levels and establishing a bullish bias.

The 20-period and 50-period SMAs on the 15-minute chart both trended higher, with price above both, reinforcing the upward momentum. A bullish engulfing pattern emerged at 05:45 ET, confirming a reversal from a prior bearish phase. Support around 143,000 and 141,000 held, while 147,000 and 150,000 appear as near-term resistance. A doji at 02:45 ET signaled indecision, followed by a strong bullish candle that invalidated bearish bias.

MACD crossed above the zero line with a strong positive histogram, indicating growing momentum. RSI hit 74 by 08:00 ET, signaling overbought conditions and the potential for a retracement. Bollinger Bands expanded sharply during the 04:00–06:00 ET rally, reflecting increased volatility and consolidation. Price remained above the upper band for over two hours, suggesting strong conviction in the rally.

Volume and turnover were closely aligned, with volume peaking at 35.5 BTC during the 05:15–05:30 ET surge. Turnover spiked to 5.1M JPY during that period, validating the bullish breakout. A mild divergence between price and volume occurred after 09:00 ET, as price continued higher while volume subsided. This could indicate a potential exhaustion phase. Fibonacci retracement levels at 144,375 (38.2%) and 146,100 (61.8%) were tested and held, suggesting further bullish continuation but with caution for pullbacks from overbought levels.

A potential backtesting strategy for this market could involve a breakout-based approach triggered by the 15-minute bullish engulfing pattern forming above the 20-period SMA. A long entry could be placed at the close of the engulfing candle, with a stop loss below the engulfing’s low. A take-profit target could be set at the 61.8% Fibonacci level of the prior bearish swing (around 146,100). A trailing stop could be added as the 15-minute RSI crosses 50 on the way up. This strategy would aim to capture the continuation of the bullish momentum while managing risk via defined stop levels. Given the recent momentum and volume confirmation, this could yield a favorable risk-reward ratio of 1:2 or better for a 24-hour to 48-hour trade window.
