Structure & Formations

Price action formed bearish continuation patterns, including key breakdowns below support levels at $0.132 and $0.133. A notable bearish engulfing pattern occurred around 2025-09-25 00:00–01:00 ET, as price moved from $0.1396 to $0.1378. A series of lower highs and lower lows reinforced the downtrend, with price testing the 61.8% Fibonacci retracement level of $0.136–0.137 before breaking below it.

Moving Averages

The 20-period and 50-period moving averages on the 15-minute chart remained above the current price, reinforcing bearish sentiment. The 50-period MA crossed below the 20-period MA during the NY close, signaling a potential shift in short-term momentum. Daily MAs (50, 100, and 200) also trended lower, confirming the bearish bias across timeframes.

MACD & RSI

MACD turned bearish, with the line falling below the signal line and remaining in negative territory, indicating ongoing selling pressure. The RSI dipped below 30 during the 2025-09-25 02:00–04:00 ET window, suggesting oversold conditions, but failed to trigger a meaningful rebound. This divergence indicates a lack of buyer participation, increasing the likelihood of further downside.

Bollinger Bands

Volatility expanded significantly during the overnight session, with the upper and lower bands widening. Price closed near the lower band, indicating a potential continuation of the bearish trend. The narrowing of bands in the early morning suggested a consolidation period before the recent breakdown.

Volume & Turnover

Trading volume spiked during the overnight and early morning hours, with a large block at 2025-09-25 00:00–01:00 ET (volume: 8,282,558.7). Notional turnover reached $43.2 million during the 24-hour period, with the majority occurring between 2025-09-25 00:00 and 04:45 ET. The divergence between price and volume suggests that the move lower is being driven by concentrated selling, not broad-based pressure.

Fibonacci Retracements

The 15-minute chart showed a key 61.8% retracement level at $0.136 being tested and then broken during the overnight session. The 38.2% level at $0.139 failed to hold during the NY open, suggesting bearish momentum. On the daily chart, the pair is trading near the 61.8% retracement of the prior upward swing, which could provide further downside if broken.

Backtest Hypothesis

The recent price action and technical indicators align with a potential backtest strategy that looks for a break below key Fibonacci levels followed by confirmation from RSI and MACD divergence. A short entry could be placed just below $0.132 with a stop above $0.135 and a target near $0.127–0.128. Given the bearish momentum and confirmation from volume and momentum indicators, this setup appears to offer favorable risk-reward for short-term bearish traders.
