Sui/Tether (SUIUSDT) opened at $3.5577 on 2025-09-17 at 12:00 ET and closed at $3.7894 one day later. The 24-hour session saw a high of $3.8308 and a low of $3.5466, reflecting significant intraday movement. Total traded volume reached 17.76 million SUI, with notional turnover amounting to $65.9 million.

Price formed a strong bullish trend over the first 12 hours, with the 15-minute chart showing a breakout from a descending triangle pattern formed between $3.55 and $3.60. A key breakout above $3.65 in the early evening hours confirmed a shift in sentiment. The formation was reinforced by a bullish engulfing pattern and a long lower shadow near the session low. A strong 15-minute close above $3.78 also signaled a possible reversal in short-term bearish pressure.

Momentum indicators showed mixed signals. The 20-period and 50-period moving averages on the 15-minute chart crossed in a bullish manner (golden cross) during the evening hours, confirming the upward trend. RSI reached overbought levels (above 70) during two spikes late in the session but failed to maintain above that threshold, suggesting possible profit-taking. MACD lines showed positive divergence with price in late-night trading, indicating that the bullish momentum could be losing steam.

Bollinger Bands widened significantly after 19:00 ET, reflecting increased volatility. Price spent most of the session above the 20-period moving average and within the upper third of the bands, suggesting a continuation of the bullish phase. Fibonacci retracements applied to the key 3.5466–3.8308 swing showed 61.8% at $3.762, which held briefly before a final push above $3.80. A breakdown below $3.75 would signal a potential pullback toward $3.72 or $3.68 for support.

The backtesting strategy relies on the convergence of multiple indicators: a bullish 20/50 MA crossover, RSI above 50, and a long lower shadow in the candle. During the 19:00–20:30 ET period, these conditions were met with high probability, suggesting a potential entry point. The strategy would look to exit once RSI reached overbought territory (70+), or if a bearish divergence appeared in the MACD. Given the current price above key resistance at $3.80 and $3.82, and with strong volume confirmation, the strategy would maintain a bullish bias for the next 24 hours, with a stop-loss consideration below $3.75.
