Optimism/Tether (OPUSDT) opened at 0.6993 at 12:00 ET–1 and closed at 0.6681 by 12:00 ET, with a high of 0.7002 and a low of 0.6564. The pair has seen a total trading volume of 9,116,014.64 and a notional turnover of approximately $6,061,179. The 24-hour candlestick pattern shows a large bearish body with no significant bullish rejection, indicating a lack of immediate buying interest.

The structure of the 15-minute chart reveals a strong bearish trend over the past 24 hours. Key support levels have formed at 0.675, 0.668, and 0.660, with a recent rejection attempt at 0.670. Resistance levels include 0.680, 0.685, and 0.690. Notable patterns include a bearish engulfing pattern at the top of the 0.699–0.696 range and a series of bearish harami candles below 0.680. These formations suggest continued downward pressure unless buyers step in above 0.675.

The 20-period and 50-period moving averages on the 15-minute chart are both in bearish alignment, with the 20-period line crossing below the 50-period line, confirming a short-term bearish bias. On the daily chart, the 50-period and 200-period moving averages have diverged, with price printing new 24-hour lows but failing to break above the 50-period line, which remains at 0.692–0.693. This divergence suggests a weakening trend and may signal a potential short-term bounce if buyers emerge near 0.668–0.670.

The MACD is in bearish territory, with the histogram turning lower and the signal line crossing below the MACD line. This reinforces the idea of diminishing bullish momentum. The RSI is currently at 35, indicating oversold conditions, but has failed to make higher lows during previous bounces, suggesting the bearish trend is intact. Bollinger Bands are widening as volatility increases, with price finding support near the lower band at 0.666–0.668. A break below the lower band could trigger a further pullback toward 0.655–0.660.

Fibonacci retracements on the 15-minute chart show the 0.675 level acting as 38.2% support, with the 61.8% level at 0.668 coinciding with current price action. On the daily chart, the 38.2% retracement is at 0.670, and the 61.8% retracement at 0.662. If buyers fail to push price above 0.675–0.678, the next support area could be found near 0.655–0.660. A breakdown below 0.665 would confirm a deeper correction and increase the risk of a 7–8% decline in the next 24 hours.

Looking ahead, the market appears to be testing critical support at 0.668–0.670. A successful bounce from this level may trigger a short-term recovery to 0.675–0.680. However, the absence of strong bullish confirmation and the bearish momentum suggest the near-term outlook remains bearish. Traders should watch for volume divergence and a potential breakdown below 0.665 as key triggers for a deeper decline.

Backtest Hypothesis: A backtesting strategy that enters short positions on a confirmed breakdown below the 0.668–0.670 support zone, with a stop-loss at 0.675 and a target at 0.655, appears aligned with the current technical structure. This approach could capture the continuation of the bearish trend, especially if the RSI remains below 40 and the MACD continues to trend lower. Given the high volume during the breakdown and the absence of bullish reversal signals, this strategy may offer a favorable risk-reward ratio over the next 48 hours.
