The price trend was predominantly bullish, especially from 18:00–21:00 ET, when a sharp upward move saw SUIUSDT rise from $3.65 to over $3.80. This was followed by a continuation phase from 21:00–24:00 ET, where the pair surged to $3.97, breaking through multiple psychological and Fibonacci retracement levels. The 20-period and 50-period moving averages were crossed decisively in favor of the bulls, with the 50-period line acting as a dynamic support during the pullbacks.

Structure & Formations

A strong bullish reversal pattern emerged around $3.56–$3.60, with a bullish engulfing pattern confirming the breakout. Key support levels were identified at $3.554, $3.604, and $3.6619, while resistance was observed at $3.768, $3.8213, and $3.8986. The most recent consolidation before the breakout showed a tight range between $3.85–$3.88, with a decisive break above $3.89 signaling renewed bullish intent.

A notable bearish divergence in RSI did not materialize during the consolidation phase, indicating strong conviction from buyers. A doji formed at $3.8936, signaling indecision, but this was quickly resolved with a strong bullish candle confirming the breakout. Fibonacci retracement levels at 61.8% of the prior downswing were pierced on the way up, with the 100% level now acting as a new psychological target.

MACD & RSI

MACD crossed above the zero line early on 2025-09-17 and remained in positive territory throughout the 24-hour period. The histogram expanded during the 21:00–24:00 ET surge, indicating increasing momentum. RSI spiked into overbought territory above 70 from around 04:00 ET, peaking at 78.5 at 14:00 ET, but did not show signs of bearish divergence. This suggests strong continuation potential rather than exhaustion at this stage.

Bollinger Bands

Volatility expanded after 18:00 ET as the price broke out of a tight Bollinger Band contraction. The price closed the 24-hour period near the upper band, suggesting a continuation of the bullish trend. The band width widened from ~0.013 at 00:00 ET to ~0.032 at 12:00 ET, indicating growing uncertainty and aggressive position-taking.

The price hovered just below the upper band for the last 8 hours, with a strong close to the upper end of the range. This positions SUIUSDT well for a potential test of the $4.00 psychological level if volatility remains elevated.

Volume & Turnover

Volume spiked during the 18:00–21:00 ET period, reaching 3.65 million units, confirming the breakout move. Notional turnover also surged during this time, peaking at $13.8 million in one 15-minute interval. The volume profile showed a clear imbalance in favor of buyers during the consolidation phase, with bearish volume waning as the price pushed higher.

Price and turnover aligned well during the breakout, with no bearish divergence observed. This confirms strong institutional or large-cap investor involvement in the move. The most active time was 09:00–12:00 ET, where a $3.85–$3.97 push was confirmed by high-volume activity.

Backtest Hypothesis

Given the strong bullish momentum and key level breakouts observed, a potential backtest strategy could involve a breakout system that enters long upon a confirmed close above the upper Bollinger Band with RSI above 60 and volume above the 14-period moving average. Exit signals could be based on a close below the 50-period EMA or a bearish divergence in MACD. This strategy would aim to capture the continuation of the current bullish trend, leveraging the confluence of technical indicators and strong volume confirmation.
