Structure & Formations

Price tested a key support level near 3.71e-6 on two separate occasions, most recently during the 10:15–10:30 AM ET window. A bullish reversal pattern formed at this level, particularly during the 10:15–10:30 AM and 10:45–11:00 AM ET sessions, as buyers pushed price back above 3.73e-6. On the bearish side, a 3.75e-6 level emerged as a short-term resistance after repeated attempts to breach it over the last 8 hours failed, with a notable rejection seen in the 9:15–9:30 AM ET window.

A small-bodied bearish candle (doji-like) formed around 3.77e-6 during the 22:45–23:00 PM ET timeframe, suggesting indecision among traders. A potential three-wave bearish pattern emerged between 3.78e-6 and 3.75e-6 from 4:45–5:00 PM to 6:30–6:45 PM ET, indicating a possible consolidation phase.

Moving Averages & Momentum

On the 15-minute chart, the 20-period moving average (EMA) was slightly above the 50-period line, but both remained in a neutral-to-bearish slope. The 50-period EMA crossed below the 100-period SMA earlier in the session, signaling a short-term bearish bias. On the daily chart, the 50-period SMA was trading below the 200-period SMA, reinforcing a longer-term bearish trend.

The MACD remained in negative territory for most of the 24 hours, with a very weak bullish crossover appearing in the early hours of 2025-09-26, but this was quickly invalidated. RSI moved into the 45–50 range by the close, suggesting a potential balance between buying and selling pressure. However, it showed signs of weakening momentum without entering overbought or oversold levels.

Bollinger Bands & Volatility

Volatility remained moderate, with price staying within the Bollinger Bands for most of the period. A minor contraction in the bands occurred between 4:45–5:00 PM ET, indicating a potential low-volatility phase, followed by an expansion during the 9:15–9:30 AM ET session. Price spent much of the session near the lower band, with a few minor rejections at the mid-band. A strong rejection at the upper band occurred during the 15:15–15:30 PM ET window, suggesting a potential ceiling above current levels.

Volume & Turnover

Volume surged during the 17:45–18:00 PM ET and 18:30–18:45 PM ET timeframes, coinciding with sharp price declines to the 3.73e-6 and 3.76e-6 levels, respectively. However, these price movements were not accompanied by a proportional increase in notional turnover, suggesting limited conviction from large participants.

A sharp increase in turnover occurred during the 23:45–24:00 PM ET window, as price tested the 3.71e-6 support level and rebounded. This was followed by a relatively quiet morning session, where price consolidated between 3.75e-6 and 3.77e-6, with volume remaining subdued. Divergence between volume and price movements during the 10:00–10:15 AM ET window suggests potential exhaustion in the bearish trend.

Fibonacci Retracements

Applying Fibonacci retracements to the recent 3.78e-6 to 3.68e-6 swing, the 3.75e-6 level corresponds to the 61.8% retracement, while the 3.77e-6 level aligns with the 50% retracement. A 38.2% retracement at 3.73e-6 has also seen repeated testing over the last 12 hours. These levels appear to be acting as both dynamic supports and resistances, with the 61.8% level showing strong buying pressure on two separate occasions.

On the daily chart, the 50% retracement of the larger 3.8e-6 to 3.68e-6 move aligns with the current price action, reinforcing its importance as a potential inflection point in the near term.

Backtest Hypothesis

Given the observed behavior around the 3.71e-6 support and the recurring bearish patterns at 3.75e-6, a potential backtesting strategy could involve a long entry at a 3.73e-6 stop-loss with a target at 3.77e-6. This approach would seek to capitalize on the bearish exhaustion and bullish reversal cues seen in the recent price action. A 3.71e-6 stop-loss would limit risk while allowing for a favorable risk/reward ratio. Testing this strategy over similar 15-minute windows in the last 30 days would help assess its viability under varying volatility conditions.
