Market Summary and Initial Observations

Bitcoin Cash/Yen (BCHJPY) opened at 77071.0 on 2025-11-07 at 12:00 ET and closed at 75098.0 by 12:00 ET on 2025-11-08.

Structure & Formations

The chart structure shows a key resistance cluster between 77500.0 and 80651.0, where the pair briefly stalled before reversing. A notable bearish engulfing pattern formed around 18:15 ET as the price closed below the prior candle’s body, reinforcing bearish momentum. Later, during the night, price drifted lower with no significant reversal patterns, suggesting bearish sentiment.

Volatility and Bollinger Bands

Volatility expanded in the early hours with the Bollinger Bands widening to over 1,000 Yen between 18:00 and 19:00 ET, coinciding with the high-volume breakout attempt to 80651.0. However, as the bearish move took hold, the bands began to contract by 04:00 ET, indicating waning momentum and a potential continuation of the downtrend.

Momentum and RSI

Relative Strength Index (RSI) readings pushed into overbought territory (above 70) briefly near 80651.0, signaling a potential top. However, the failure to hold above that level led to a rapid RSI decline below 50, then into oversold territory (below 30) by 06:00 ET. This suggests strong bearish momentum and potential exhaustion for any short-term buyers.

Backtest Hypothesis

Given the RSI readings and observed price behavior, a backtesting strategy could be implemented using the standard 14-period RSI with oversold at 30 and overbought at 70. This would generate buy signals when RSI dips below 30 and sell signals when it exceeds 70. The strategy would be tested on historical BCHJPY data from 2022-01-01 to the present, aiming to evaluate the profitability of such a system in capturing short-term momentum swings.
