Structure & Formations

Price action revealed a bearish trend throughout the session, with a key resistance level forming around 4.54e-06 and a strong support near 4.25e-06. A long lower wick on the 15-minute chart at 00:45 ET suggests rejection at higher levels. A bearish engulfing pattern appeared during the early hours of 2025-09-19, confirming a continuation of the downward trend. A doji candle at 06:15 ET signaled indecision amid the bearish sentiment.

Moving Averages

The 20-period and 50-period moving averages on the 15-minute chart remained bearishly aligned, with the price trading consistently below both. On the daily chart, the 50-period MA sits at 4.42e-06, while the 200-period MA is near 4.38e-06, suggesting the market is below both significant trend indicators, reinforcing the bearish bias.

MACD & RSI

The MACD line crossed below the signal line early in the session and remained in negative territory, indicating a sustained bearish momentum. RSI dipped into oversold territory, reaching as low as 30, which may suggest a temporary bounce is possible. However, without a corresponding surge in volume, this bounce could remain limited.

Bollinger Bands

Volatility remained elevated, with the price oscillating near the lower Bollinger Band, indicating a bearish bias. The recent widening of the bands suggests increasing uncertainty in the market. A consolidation phase may be necessary before a breakout, but given the trend, a breakdown seems more likely.

Volume & Turnover

Volume spiked significantly during the early hours (00:45–01:30 ET), but the price failed to hold above 4.52e-06, highlighting a divergence. Later, volume declined despite price action suggesting continued selling pressure, pointing to a potential exhaustion in the short term. Turnover also reflected the same pattern, with spikes aligning with key support and resistance levels.

Fibonacci Retracements

Applying Fibonacci levels to the recent 15-minute swing from 4.54e-06 to 4.25e-06 identified key retracement levels at 4.46e-06 (38.2%) and 4.41e-06 (61.8%). Price tested both levels, with 4.41e-06 holding briefly before another decline. A retest of 4.41e-06 could see renewed selling pressure, potentially leading to a test of 4.25e-06 again.

Backtest Hypothesis

Given the bearish momentum, a potential backtest strategy could involve entering a short position after a bearish engulfing pattern and confirming with a close below a key Fibonacci retracement level. Stop-loss placement above the 4.46e-06 resistance level and a take-profit target at 4.25e-06 could be used. The low RSI and volume divergence suggest caution in entering new long positions, with a short-term bias favoring bearish setups. However, market conditions could shift rapidly with increased volatility and a breakout above 4.54e-06 would negate this approach.
