• Portal/BNB traded in a narrow range before a sharp breakout in late ET, signaling growing institutional interest.
• Price rose from 2.08e-05 to 2.26e-05, with strong volume accumulation seen in the last 4 hours of ET.

The 24-hour period for Portal/BNB (PORTALBNB) on October 31, 2025, began at 2.13e-05, reached a high of 2.26e-05, and closed at 2.22e-05. The low of the session was 2.08e-05. Volume was largely muted in early ET but surged in the final hours, with notable accumulation between 05:15 ET and 06:30 ET. Total volume amounted to 169,285.5, while turnover (volume × price) reflects strong notional participation of approximately $3.86.

Structure and key levels show that the price found strong support at 2.08e-05 during the late ET hours and built a bullish formation as it moved higher. A bearish engulfing pattern was seen briefly at 17:45 ET but was quickly negated by the upward thrust. The 2.13e-05 level acted as a psychological floor, and resistance formed at 2.18e-05 and 2.22e-05. A breakout above 2.23e-05 could signal renewed bullish momentum and target the next resistance at 2.26e-05.

Moving averages on the 15-minute chart show a sharp crossover of the 20 and 50-period lines in the early hours of the morning, aligning with the breakout. This suggests a shift in momentum toward the bulls. On a daily basis, the 50-period moving average has been acting as a dynamic support, and as long as it holds, the bias remains cautiously optimistic.

MACD turned positive in the final 4 hours of the session, confirming the strength of the move higher. RSI, while still within healthy territory, is approaching 55, suggesting the price is not yet overbought but is consolidating after a sharp move. Bollinger Bands reflect a moderate contraction in volatility during the early hours, followed by a widening as price pushed higher—this often signals increased activity ahead.

Backtest Hypothesis
Given the bullish engulfing and breakout seen in the 15-minute chart, and the subsequent MACD confirmation, a possible backtesting strategy could focus on long entries at the close of the breakout candle, with a stop-loss just below the 2.08e-05 support. A target would be the 2.18e-05 to 2.23e-05 range, with a risk/reward profile of roughly 1:1.2. This strategy could be tested using historical data to determine how often such patterns lead to successful short-term moves in the PORTALBNB pair.
