Structure & Formations

Price action on the 15-minute chart displayed a consistent bearish tilt with multiple confirmed breakdowns below key levels. A significant bearish engulfing pattern appeared on the 09:45–10:00 ET candle, confirming the downtrend. A key support area was retested at 0.000317 (09:30–10:45 ET), showing minimal rejection and suggesting that bearish sentiment is firmly in place. A potential resistance zone at 0.0003224–0.000322 was tested four times, with bearish rejection evident on each attempt.

Moving Averages and Momentum

On the 15-minute chart, price remained below both the 20 and 50-period moving averages for the majority of the session, reinforcing bearish bias. On the daily chart, the 50/100/200 SMA lines are not explicitly defined in the given data, but based on the 15-minute pattern, price appears to have diverged from its 50-day mean, aligning with short-term bearish momentum.

The RSI showed a steady descent from ~60 early in the session to ~25 by the close, suggesting bearish exhaustion may not yet be at an oversold threshold. MACD lines remained below zero for most of the session, with negative divergence in the histogram reflecting declining bullish momentum.

Bollinger Bands and Volatility

Volatility expanded significantly during the 03:45–04:45 ET window, as evidenced by a widened Bollinger Band range. Price moved from near the upper band (0.0003261) to the lower band (0.0003189) within a few candles. This expansion was followed by a brief consolidation phase between 04:45–06:00 ET, during which price traded within the bands but remained below the 20-period SMA.

Volume and Turnover Analysis

Volume spiked to 2377.9 at 04:15 ET, coinciding with a sharp drop to 0.0003189. Additional spikes occurred at 05:15 ET and 15:00–15:30 ET, with the largest turnover concentrated in the 15:00–16:00 ET window. Despite these spikes, price failed to retest higher levels above 0.0003202, suggesting potential exhaustion or a lack of follow-through from sellers. A bearish volume divergence was observed between 09:45–10:45 ET, where price continued lower while volume remained subdued.

Fibonacci Retracements and Key Levels

Applying Fibonacci retracements to the 15-minute move from 0.0003309 to 0.000317, key levels were seen at 38.2% (0.0003242), 61.8% (0.0003207), and 78.6% (0.0003185). Price tested the 61.8% level (0.0003207) around 04:30 ET and 10:30 ET with bearish rejection. The 78.6% level at 0.0003185 acted as a temporary floor twice, most recently on 11:30 ET, with price failing to hold above it.

Backtest Hypothesis

Given the bearish momentum confirmed by RSI divergence, MACD weakness, and volume rejection at key resistance levels, a backtest strategy could be designed to short SEIBNB upon a confirmed close below 0.0003185. Stops could be placed above the 0.0003224 resistance level, with initial take-profit targets at 0.000316 and 0.000314. The strategy would aim to capture continued bearish momentum while managing risk through tight stop levels. If the RSI approaches 20 without a reversal signal, the trade could be extended. However, a breach of 0.0003224 would invalidate the bearish thesis and signal a potential reversal.
