Key resistance is forming at 3.53e-06 and 3.57e-06, while support appears at 3.45e-06 and 3.49e-06. A notable bearish breakout occurred around 22:00 ET as price dropped from 3.55e-06 to 3.51e-06 in a single 15-minute interval, suggesting ongoing bearish control. Doji and small-bodied candles indicate indecision, while engulfing patterns during the overnight session (01:15–03:15 ET) confirmed a bearish trend continuation.

The 20-period and 50-period moving averages on the 15-minute chart remained above price action, reinforcing bearish bias. Intraday momentum appeared to weaken as RSI entered oversold territory below 30 for most of the session. MACD remained negative with no clear sign of a bullish crossover. Bollinger Bands were relatively narrow for much of the session, indicating low volatility, but widened slightly during the overnight decline.

Volume spiked moderately during the overnight hours and again around 09:30 ET when price broke the 3.49e-06 level, suggesting bearish confirmation. No significant divergences were observed between price and turnover. Fibonacci retracement levels from the 3.45e-06 to 3.57e-06 swing indicate potential support at 3.51e-06 (38.2%) and 3.48e-06 (61.8%), with the latter forming a potential key level for a near-term bounce.

The backtest hypothesis for the HEIBTC pair is based on a short-term mean reversion strategy using the 20-period and 50-period moving averages in conjunction with RSI divergence. The strategy would initiate a short position when price crosses below both the 20- and 50-period MAs on the 15-minute chart and RSI shows bearish divergence (price makes higher lows while RSI makes lower lows). Stops would be placed just above the nearest swing high, with a target near the 61.8% Fibonacci level. The setup would also require a minimum volume trigger of 100 BTC per candle to confirm conviction. This approach aligns with the recent bearish confirmation seen in the overnight hours and appears to offer a favorable risk/reward profile for the next 24-hour window.
